PricePlow is an organization of patriots, so after all we love ‘Merica Labz for doing every part with an unapologetically American aptitude.
This implies going massive, taking issues to the boundaries, and testing the boundaries of complement conference within the best custom of American innovation.
At present we’re going to speak about Fortress Bravo, named after the most important thermonuclear bomb ever detonated. Now that’s the way you set the tone.
Fortress Bravo is designed that will help you explode into the fitness center and incinerate each single set that’s in your lifting schedule.
True to type, ‘Merica Labz went massive on the stimulants – right here we now have a formidable 450 milligrams of caffeine, so watch out with this one! After the discharge of F-BOMB, a lot of Merica Labz’ followers in all probability gained’t have a difficulty with it, however many might want to go together with lower than a scoop — which might nonetheless convey loads of citrulline since Merica went massive there as effectively (7 grams).
In fact, thermonuclear conflict isn’t nearly brute power – a variety of scientific evaluation and mental precision goes into it as effectively. For that we now have elements like alpha-GPC and huperzine A, which can assist get your thoughts and your physique razor sharp to deal with the psychological challenges of a tricky exercise.
Let’s get into it, however first join PricePlow’s Merica Labz information alerts and examine our coupon-powered offers:
In a single 1 scoop (20.8 gram) serving of Fortress Bravo from ‘Merica Labz, you get the next:
L-Citrulline – 7000 mg
Merica’s not nearly massive vitality – they went massive with pumps too!
Citrulline is actually an all-star pre-workout ingredient. Apart from caffeine, it’s essentially the most generally used ingredient within the class – and it’s undoubtedly the commonest nitric oxide (NO) booster.[1]
Citrulline is a conditionally important amino acid. This implies your physique can produce some by itself, however not essentially sufficient to cowl all of your metabolic necessities. This is the reason we virtually all the time see extra profit from supplemental citrulline.
Conditional amino acid necessities are likely to go up due to train – so athletes specifically ought to take into account supplementation, particularly in order for you some vasodilation to drive extra blood, extra vitamins, and extra beneficial properties.
Citrulline to NO conversion pathway
Citrulline really doesn’t get transformed immediately into NO. First it will get transformed into arginine – after which the arginine will get transformed into NO. So the total conversion pathway seems like Citrulline → Arginine → NO.
Most individuals will have a look at this and surprise why we don’t simply take arginine as a substitute – and the reply is that citrulline’s bioavailability is way increased than arginine’s when taken orally.[2,3]
Thus, citrulline supplementation is a greater technique than arginine supplementation for growing arginine blood ranges – and therefore, NO blood ranges.
Advantages of NO upregulation
What’s the purpose of accelerating NO ranges?
Upregulated NO causes vasodilation, a course of by which the sleek muscle tissue lining the within of your arteries relaxes.

The Arginine Citrulline Cycle with a breakout displaying the arginine-to-nitric oxide response. Picture courtesy Wikimedia with added biochemistry sources.[4,5]
This permits your arteries to develop in diameter, and the larger arterial capability naturally results in reductions in blood stress and coronary heart fee, because you’re utilizing a much bigger area for a similar quantity of blood. It additionally signifies that circulation is extra environment friendly, permitting for higher supply of vitamins to cells and sooner removing of metabolic waste.[6-8]
Due to this, elevated cardiovascular effectivity normally interprets into improved athletic efficiency. As an illustration, lactic acid causes muscle fatigue because it builds up, and will be eliminated extra shortly than normal throughout vasodilation. Thus, vasodilation normally comes with an endurance-boosting impact.
For a similar causes – improved nutrient supply and waste removing – restoration after train may also be higher.
However don’t take our phrase for it! Let’s check out what the analysis has to say about the advantages of citrulline supplementation:
- Elevated energy output and oxygen uptake[9]
- Higher athletic endurance – 50% extra![10]
- Much less muscle soreness post-workout[10]
- Elevated progress hormone (GH) manufacturing and secretion[11]
- Diminished protein breakdown[12]
- Higher muscle beneficial properties[13,14]
Ornithine – antitoxin, antistress
So citrulline is a good NO booster – and let’s be trustworthy, most of us have heard that earlier than.
What’s much less generally mentioned is that citrulline dietary supplements may also enhance your physique’s manufacturing of ornithine,[15] which is an amino acid that’s concerned in ammonia cleansing.[16]
Ammonia’s one other metabolic waste – it causes psychological and bodily fatigue because it accumulates in numerous tissues. In different phrases, elevated ornithine manufacturing by way of citrulline supplementation is one more approach that citrulline can enhance endurance
Moreover, the removing of waste is a vital think about restoration.
Ornithine is nice for extra than simply efficiency and restoration, although – it will possibly additionally enhance sleep high quality, which is clearly necessary for not solely efficiency and restoration, but additionally for general well being and wellness.

You shouldn’t want extra pump, however in case you do, take a look at ‘Merica Labz new stim-free pre-workout, F’n Pump’d. Merica additionally has Stars ‘n Pipes.
A 2014 examine discovered that L-ornithine supplementation considerably improved sleep high quality in wholesome employees, not less than partly as a result of it improved their ratio of DHEA to cortisol.[16]
The dose
This 7,000 mg dose is superior, going above and past the normal 3-6 grams we see. It’s greater than twice the clinically-verified 3 gram dose, and fairly close to the ten,000 mg mark, which is the place beneficial properties on extra citrulline supplementation start to decrease.[17] Since citrulline’s results are dose-dependent,[18] extra is mostly higher.
In case you are patriotic sufficient, you may all the time stack it with F’n Pump’d to get much more. That stack could possibly be reserved for the monster arm days the place you’re OK getting so pumped you gained’t be capable of transfer a lot.
Beta Alanine – 3,200 mg
Subsequent we now have one other pre-workout famous person, beta alanine.
It’s generally accepted that beta alanine belongs to a class of dietary supplements named ergogenic aids. The etymology of this phrase actually means “work creating,” and refers back to the potential of those dietary supplements to enhance athletic efficiency by growing one’s capability for bodily work.
Like citrulline, beta alanine has been round eternally, and might be round for a very long time to return. It’s low-cost, protected, and efficient.
Beta alanine + histidine = carnosine

We’re thinking about part (B) right here, the place beta alanine alone exhibits nice outcomes in comparison with placebo.[19]
The explanation we like beta alanine is that when mixed with the amino acid L-histidine, it types a dipeptide molecule named carnosine. Carnosine is necessary as a result of it’s one of many mechanisms your physique makes use of to eliminate lactic acid.[20]
Recall from the earlier part that lactic acid accumulation causes muscular fatigue – so once more, eliminating it sooner by way of carnosine upregulation can enhance athletic endurance.
So why not complement with carnosine as a substitute?
As soon as once more, similar to arginine (within the case of citrulline), carnosine itself shouldn’t be very bioavailable when taken orally. Beta alanine, then again, is – and since histidine is actually considerable in widespread meals, your physique’s entry to beta-alanine is nearly all the time the bottleneck on its manufacturing of carnosine.[21,22]
Which means supplementing with beta alanine is essentially the most dependable method to enhance carnosine manufacturing.
Endurance enhance: meta-analyses
Two massive meta-analyses on beta alanine supplementation,[19,23] reviewing over 40 totally different research discovered that it’s greatest at enhancing train efficiency when train is carried out at a selected depth: particularly, an depth that may be sustained for anyplace between 30 seconds to 10 minutes. There are quite a few athletic functions for the ingredient, too.[19-27]
The dose
3,200 mg is the usual dose, mostly used and studied by far. You might be good to go together with this one.
PeakO2 (Cordyceps (Cordyceps militaris), Reishi (Ganoderma lucidum), King Trumpet (Pleurotus eryngii), Shiitake (Lentinula edodes), Lion’s Mane (Hericium erinaceus), and Turkey Tail (Trametes versicolor)) – 2,000 mg
PeakO2 is a proprietary mix of adaptogenic mushrooms. These mushrooms have many advantages, together with anti-inflammatory, anti-oxidant, anti-aging, anti-fatigue, and even sexual efficiency advantages.[28,29]

That’s all nice, however the profit we’re most thinking about for the needs of Fortress Bravo is the one which impressed the title “Peak O2” – elevated oxygen utilization. This could translate into improved VO2max, endurance, and energy output. Let’s have a look at the three research carried out particularly on PeakO2:
-
2015 examine: Peak O2 can enhance cardio efficiency
The primary examine on Peak O2 got here from researchers on the College of North Carolina in 2015.[30] On this randomized, double-blind, placebo-controlled examine – the gold customary of scientific analysis – topics received both 1.3 grams of Peak O2 or 1.3 grams of a maltodextrin placebo 3 instances per day.
By the top of the three-week examine interval, the Peak O2 group had considerably increased peak energy, VO2max, and time exhaustion. The placebo group noticed no important modifications in any of those parameters.[30]
-
2016/2017 examine: Peak O2 results at 2 grams
In 2016, that very same workforce of researchers returned with extra members and extra knowledge, displaying that Peak O2 was after three weeks.[31] On this examine, they once more gave 4 grams per day or placebo.
After one week of supplementation, there weren’t statistically important results. Nevertheless, after three weeks, VO2max considerably improved within the PeakO2 customers, in addition to time to exhaustion.[31]
Nevertheless, that was 4 grams per day – greater than we now have right here. Can 2 grams be efficient as effectively?
-
2018: Quicker results at larger doses, however efficient at 2 grams over time
The primary two research used 4 grams, nonetheless, which is so much. So in 2018, one other workforce of researchers revealed a follow-up examine testing lower-dosed PeakO2 (2 grams per day, what we now have right here) over 28 days towards a better dose of 12 grams per day in 7 days. They discovered that the lower-dose group took an extended period of time to attain advantages, however nonetheless achieved statistical significance in 4 weeks concerning:[32]
- Elevated time to fatigue
- Elevated VO2peak
- Decrease blood lactate ranges.
This is the examine we’re in search of – a 2 gram dose that doesn’t overwhelm you with mushrooms – and after 4 weeks, it does have results.
Different advantages
The person elements on this mix have been extensively studied. Here’s a partial listing of their research-backed advantages:
- Cordyceps: improves train tolerance,[31] boosts immunity[33]
- Reishi: 5 alpha-reductase inhibitor[34] and anti-estrogen[35]
- King trumpet: testosterone booster,[36] incorporates testosterone imitators[37]
- Shiitake: immune boosting[38]
- Lion’s mane: antioxidant, anti-lipidemic, neuroprotective, nerve regeneration[39-41]
- Turkey tail: anti-oncogenic, immune boosting[42,43]
L-tyrosine – 2,000 mg
Pre-workout customers sometimes have two massive issues in widespread: they exercise laborious, they usually food plan laborious. L-Tyrosine may help with each. This amino acid is nice for neurotransmitter manufacturing, thyroid hormone manufacturing, and alertness throughout sleep deprivation.
Neurotransmitter manufacturing
Tyrosine is the precursor to dopamine, adrenaline, and noradrenaline.[44-46] These catecholamine neurotransmitters are essential for focus, motivation, and vitality.

It’s straightforward to see why we like tyrosine a lot – its derivatives convey the depth and focus! Picture courtesy Wikimedia
In addition they management your physique’s stress response, which is necessary for performing effectively throughout your exercises.
Adrenaline and noradrenaline can help in physique recomposition, as they suppress urge for food and velocity up the speed at which your physique burns fats.[47]
Nice for sleep deprivation
Imagine it or not, a variety of tyrosine analysis comes from militaries, who’re thinking about its potential to advertise wakefulness and application. Based on a examine carried out by the United States army, tyrosine is even higher than caffeine at doing this.[48,49]
Thyroid

Lengthy story quick from our evaluation — For one of the best results from tyrosine, select the common L-Tyrosine model!
Though you don’t normally hear the thyroid introduced up within the context of pre-workout components evaluation, it’s one thing that it is best to take into account. In spite of everything, the thyroid is actually your metabolic grasp gland. If you would like your athletic efficiency, cognition, and physique composition on level, you want correct thyroid operate.
Because it seems, the 2 massive behaviors we named earlier – figuring out and weight-reduction plan – can take a toll on thyroid operate,[50-52] because of their cortisol-raising impact.
When your thyroid is subjected to emphasize, it normally causes a drop within the manufacturing of triiodothyronine (T3) and thyroxine (T4), your thyroid hormones – and tyrosine is the precursor to those hormones.[53,54]
So in case you’re working laborious to construct muscle and acquire fats, supplemental tyrosine is likely to be a good suggestion.
Caffeine Anhydrous – 350 mg (of 450 whole)
Caffeine wants no introduction. Virtually all people studying (and writing) this text makes use of some sort of caffeinated beverage to assist them cope with the calls for of their busy schedule.

Patrick Mabe (@mr.patrick.mabe) of Core Nutritionals, Merica Labz, and Merica Vitality joins the PricePlow Podcast Episode #073 to debate his competitors within the Tactical Video games, fatherhood, and residing the Crush It Life-style at Core Nutritionals in North Carolina!
That’s as a result of caffeine inhibits adenosine, a nucleotide that builds up in mind tissue when you’re awake and ordinarily produces fatigue.[55-59]
Between this and the 200 mg caffeine citrate (50% caffeine by weight) in Fortress Bravo, there are 450 milligrams of caffeine per serving. Watch out with this! It’s a variety of caffeine. Should you aren’t positive whether or not you may deal with it, ask your physician!
Efficiency booster, particularly at these excessive doses
Caffeine is taken into account an ergogenic help that improves a number of dimensions of athletic efficiency, together with however not restricted to endurance, power, and energy output.[51] Analysis signifies that “efficiency advantages will be seen with reasonable quantities (~3 mg.kg-1 physique mass) of caffeine“[51] — which we undoubtedly have right here.
However in case you’re keen to go increased with Merica Labz, there’s even extra analysis when you’re over the 5mg/kg dose! That is usually 400+ milligrams of caffeine, relying in your weight. And quite a few research have proven elevated power, endurance, and general efficiency at increased doses![60-72]

Identified since 1991, very excessive dose caffeine can severely enhance efficiency.[60] As you may see, it’s fairly variable amongst customers – future analysis would present that caffeine’s results rely in your genotype.
Curiously, a examine confirmed that even customers who habitually consumed 350 milligrams of caffeine per day nonetheless had important ergogenic advantages when going massive at 6 milligrams per kilogram of physique weight.[72]
There’s extra to the story although – genetics play a serious position as newer research are differentiating throughout totally different genotypes.[68,70]
Should you’re within the above few paragraphs, you may learn the 2018 evaluation titled “Are the Present Pointers on Caffeine Use in Sport Optimum for Everybody? Inter-individual Variation in Caffeine Ergogenicity, and a Transfer In direction of Personalised Sports activities Vitamin”.[73]
Caffeine and physique composition
Caffeine can be nice for physique composition: it drives a course of referred to as thermogenesis, by which your physique burns energy for warmth.[55,56]
It does this by inhibiting an enzyme referred to as phosphodiesterase, which is accountable for breaking down cyclic adenosine monophosphate.[55,56] Since cAMP is a messenger that tells your cells to burn energy, growing cAMP by way of phosphodiesterase inhibition is an effective way to velocity up your metabolism.[50]
This may help you shed pounds sooner, but additionally makes extra vitality obtainable for exercises, so it’s a part of caffeine’s ergogenic impact.
Alpha-GPC 50% (L-alpha glycerylphosphorylcholine) – 300 mg
Alpha-GPC is a specific type of choline, a B vitamin that performs some fascinating roles in your physique. Amongst these, it’s wanted for the development and upkeep of the phospholipid bilayer membranes that encompass the contents of all of your physique’s cells.[74]
It’s additionally wanted for the signaling between cells by which these membranes are concerned.[75]
Choline can be a precursor to the neurotransmitter acetylcholine, which we frequently name the studying neurotransmitter due to how necessary it’s for studying and reminiscence.[76] Growing acetylcholine by way of choline supplementation can enhance cognitive efficiency above baseline.[52,77]
Choline can be wanted to donate methyl teams for the aim of methionine metabolism. With out this course of, methionine can construct as much as unacceptably excessive ranges in your blood, which raises the danger of heart problems.[65
Alpha-GPC is highly bioavailable and crosses the blood-brain barrier.[78]
Pine Bark Extract (Pinus pinaster) (95% Proanthocyanidins) – 250 mg
Subsequent we now have one other nice NO-boosting ingredient – pine bark extract (PBE), which contributes to vasodilation.
Pine bark is stuffed with highly effective antioxidant phenols[79,80] that may shield endothelial nitric oxide synthase (eNOS), the enzyme that’s accountable for producing a lot of your physique’s NO, from being degraded by oxidative stress.
Pine bark’s results on cardiovascular operate, its antioxidant properties, and anti inflammatory results are so palpable that it’s been used for a whole lot of years as a folks treatment.[79,80]
Within the trendy period, scientific analysis has discovered that pine bark extracts can have important cardioprotective results.[79,80]
It could cut back systemic irritation so considerably {that a} drop in neurological illness danger from pine bark extract supplementation has been noticed.[80]
Caffeine citrate (yields 50% caffeine) – 200 mg (yields 100 mg of 450 mg whole)
Caffeine citrate provides you an identical advantages as anhydrous. It’s generally utilized in pre-workouts as a result of it appears to act sooner than caffeine anhydrous, giving a extra instant enhance in psychological and bodily vitality.
It’s even particularly been used to deal with respiration issues in infants.[81] There is likely to be respiratory advantages in adults too, however no analysis has been carried out on the topic.
In any case, at a minimal, that is giving us one other 100 mg caffeine, because it’s 50% caffeine by weight.
Be aware that the caffeine citrate brings the whole dose of caffeine in Fortress Bravo as much as 450 milligrams. It is a massive dose of caffeine! Should you’re undecided whether or not you may deal with this, ask your physician!
ElevATP (Historical Peat Extract and Apple Extract) (fruit) – 150 mg
Subsequent up we now have ElevATP, a promising ergogenic ingredient that helps your physique do extra.
ElevATP helps your physique’s ATP manufacturing.[82] Taking it will possibly enhance your physique’s extracellular ATP focus,[82,83] which may help efficiency as a result of ATP is your physique’s vitality forex.

ElevATP doesn’t comprise ATP, however as a substitute has many compounds that may help your physique’s manufacturing of ATP.[82]
In case your physique have been an engine, ATP could be the fuel – we don’t wish to run out of fuel!
In a single 2016 examine, ElevATP supplementation for eight weeks triggered important will increase within the examine members’ barbell lifts, in addition to vertical leap velocity and energy.[84]
Should you have a look at the unique examine on elevATP revealed in 2013, you’ll get have a look at the composition, which we’ve included to the proper. It incorporates many catechins, phenols, and acids that help ATP manufacturing.
As long as the ingredient has remained unchanged over the previous decade, the first constituent is 5-O-Caffeoylquinic acid, often known as neochlorogenic acid, a pure polyphenol that’s an isomer of chlorogenic acid.
Theobromine HCl – 100 mg
Theobromine is a methylxanthine alkaloid. This is similar class that features caffeine. It has stimulant, bronchodilatory – i.e. airway-opening – and vasodilatory results.[85]

Caffeine has three main metabolites, and considered one of them (paraxanthine) does the heavy lifting. The opposite two have very lengthy half-lives, which might hold the vitality coming! Picture courtesy Wikimedia
Similar to caffeine, theobromine inhibits phosphodiesterase, thus growing cyclic adenosine monophosphate (cAMP) ranges[86] and rushing up your metabolism.[87,88]
In comparison with caffeine, although, theobromine is significantly better at enjoyable clean muscle,[89] which is the mechanism behind vasodilation. Thus, theobromine can really lower blood stress, whereas caffeine will increase it.[90]
When given together with caffeine, theobromine can in truth cancel out caffeine’s blood stress elevating impact.[90] This potential of theobromine to provide the upside of caffeine with considerably much less draw back makes it a sensible ingredient for caffeine-containing pre-workouts, and we’re anticipating to see it present up much more sooner or later.
Theobromine additionally will increase nitric oxide manufacturing and signaling.[91]
Synephrine HCl – 30 mg
Synephrine prompts the beta-3 adrenergic receptors in your physique fats,[92] inflicting cyclic adenosine monophosphate (cAMP) upregulation that finally hastens the speed at which your cells burn energy.[93]

Synephrine is a fast beta agonist in comparison with some others which might be now not utilized in dietary supplements.
Though synephrine’s results resemble these of stimulants, the beta-3 adrenergic pathway has a relatively gentle impact on coronary heart fee and blood stress.[92]
In a single 2016 examine, topics who took synephrine burned much more fats throughout their exercise than topics who received a placebo – about 30% extra fats, to be extra exact.[94]
A 2015 examine discovered that taking synephrine and caffeine together can synergistically enhance fats burning.[95]
So right here we now have some extra ergogenic and fats burning help that brings among the thermo to the thermonuclear bomb that’s Fortress Bravo.
Huperzia serrata Extract (leaf and stem) (1% Huperzine A) – 20 mg
Huperzine A is one other complement that reinforces acetylcholine ranges. Nevertheless, not like alpha-GPC, which boosts acetylcholine by growing manufacturing, huperzine A does it by inhibiting acetylcholinesterase, the enzyme accountable for degrading acetylcholine.[96]
In different phrases, it makes the acetylcholine you could have last more, and pairs effectively with the alpha-GPC in Fortress Bravo.
Huperzine A is a strong acetylcholine booster – it doesn’t want to be stacked with alpha-GPC,[97] however seeing these two elements mixed is nice as a result of they’ll give synergistic results.
Huperzine A can be a potent antioxidant. It’s significantly good for safeguarding mitochondria in your mind from oxidative stress.[98]
Actually, you shouldn’t have to stack a lot with this, caffeine is just about topped out and the 7 grams of citrulline ought to be lots. However in case you have been to have an enormous arm day… going with F’n Pump’d is the one method to go! Until you go together with Stars ‘n Pipes, which is the different method to go.
Fortress Bravo is aptly named! You might be undoubtedly going to really feel this one. This text gave us an opportunity to go over our high-caffeine analysis — there are just too many analysis trials to disregard that present efficiency and endurance beneficial properties on this degree of caffeine. Generally, you gotta do what you gotta do.
And alongside that massive dose of caffeine, we even have a good dose of synephrine to prime it off. Actually, the synephrine dose is rather less than we’ve seen from ‘Merica Labz, and Merica’s not afraid to go even increased on caffeine (as proven in F-BOMB’s 473 milligrams of caffeine).
Some shoppers may miss the massive stim cocktails of pre exercises previous, however for many, we expect the brand new method will work higher – particularly in order for you clinically-demonstrated efficiency results of massive caffeine.
