Review of Sheer Strength NO2 Nitric Oxide Supplement

Nitric oxide supplements are all the rage among bodybuilding aficionados. This Sheer Strength Labs NO2 review will explore its ingredient profile, the company's quality control certification, price range and more.

Rating: 4.5 (out of 5)

Welcome to this review of the Sheer Strength NO2 nitric oxide supplement booster product. This company says they are “the premiere brand of sports supplements.” Is it true?

Well, in part that is what this review is all about. Nitric oxide supplements are very popular in the  marketplace among bodybuilders and power lifting enthusiasts.

It has become widely heralded as not only a pre-workout supplement product but a muscle building supplement as well, giving weight trainers a double benefit.

If a bodybuilding supplement can, as its makers says, “build muscle fast, boost performance and build muscle [while] increas{ing] workoutendurance that is “guaranteed,” that is a lot to live up to. If it can, it’s then the supplement of choice. Plus, it would be then easy to see why nitric oxide products are so popular among weight training aficionados.

Product Quality

As you may know, I start all my reviews talking about the product’s quality control. Supplement fraud used to be so utterly rampant but the US government has been curtailing it and have made significant strides to help consumers.

One of the most prominent things they’ve done is to pass into law GMP (good manufacturing practices) in 2009. The irony, though, is while it’s now literally illegal to not have GMP-certification, the FDA doesn’t enforce it.

They leave the industry to police itself. They do so through one of six organizations that conduct the yearly GMP audit, which auditing process is quite rigorous. The auditing comprises everything from employee training to cleanliness of facility to the certification of banned substances to manufacturing process all the way to bottling.

Currently, Sheer Strength Labs is not a GMP-certified operation. Does that mean that they don’t have quality products? No, not necessarily, but in the highly competitive world of sports nutritional supplements, they need to get this.

Sheer Strength NO2 Features & Benefits

Let’s now talk about the product in more detail. Nitric Oxide, or nitrogen oxide, helps the arteries to relax and even work more efficiently and this in turn helps to improve blood flow throughout the body. Nitric oxide is a very popular muscle building supplement.

It should not be confused with nitrous oxide an anaesthetic and greenhouse gas (the Wikipedia entry memale bodybuilderntions this too and rightly so). It is a signalling molecule that has a vital role physiological and pathological processes.

For bodybuilders and weight trainers in general, this nutrient helps to facilitate blood flow to your muscles. It even works for women as well, of course.

One of the key ingredients it has is L-Arginine, which amplifies nitric oxide production in your body for the expediting of muscle growth. The primary benefits are:

  • Faster muscle growth
  • A tangibly enhanced muscle pump
  • A healthier heart

Those three elements are its “core competencies.” Thus, this supplement is designed to amplify all three — especially an enhanced pump, which is why it’s a pre-workout supplement, and the facilitation of muscle synthesis. Moreover, the benefits of this product basically help you grow stronger with more energy in your workouts.

(Some testimonials on the product declare that it enhances blood flow to the male sexual organs as well, enhancing sexual prowess.) Natural testosterone boosters are also nothing new in terms of product offerings from Sheer Strengths Labs.

It’s the ingredient profile that Sheer Strength Labs says makes this a powerhouse bodybuilding supplement. The ingredients that comprise 3,000mg is a proprietary blend are:

  • L-Arginine HCL — its inclusion helps to heal wounds by increasing blood flow, helps the kidneys to remove waste from the body and to maintain immune and hormone function (hormone function is especially important to bodybuilders in this dietary supplement context)
  • L-Arginine (Alpha Keto Glutarate)
  • Citruline Malate
  • Beet root

Those are the core ingredients. Some other filler ingredients are:

  • Croscarmellose sodium (an emulsifier)
  • Magnesium stearate (a filler)
  • Microcrystalline cellulose (a binder)
  • Stearic acid (a binder)

How should the product be used? Sheer Strength labs recommends taking four capsules before your workout and on non-workout days, take four in the morning.

Sheer Strength NO2 Side Effects

This product is safe for usage by bodybuilding and fitness enthusiasts. However, Sheer Strength Labs has on the label the recommendation to talk to a licensed health care professional if you have a litany of health issues like prostate enlargement, heart arrhythmia, heart disease, liver problems, diabetes, seizure disorder like epilepsy, and more.

They recommend also that the product not be used by pregnant or lactating women or those under the age of 18. Lastly, a small minority say it can cause stomach upset and a headache.


This product has a price range of $28.97 to $44.66 USD (United States Dollar) on Amazon. Free shipping is also available for orders over $35 USD so that may be of interest to you as well.


Sheer Strength is very confident in this product. They guarantee it. Plus, they say if you are not satisfied, return it — even an unused bottle — and they will give you your money back. Like most vendors, they defer to the retailer’s return policy. That’s one of the reasons why I recommend one-year guaranteeAmazon.

Amazon has a great return policy and guarantee all their purchases. They’ve also got great customer service having won for nine straight years the coveted ForeSee Experience Index for best customer service. They also have the best prices as many vendors are competing against each other to get your business. The result is you get lower prices.

Sheer Strength NO2 Customer Reviews

This product is classified as “Best Seller” status on Amazon. As of this writing, it has a ranking of 4.4 out of 5.00 with 663 reviews tabulated. Why do I include real customer reviews in this particular review? Because customer opinions are more valuable as they are completely devoid of personal or corporate interest. A company will shine the best light on its products as it possibly can, and this is understandable. But customer reviews are almost always pure and unbiased and based solely on their experience with a product. That said, here are a few testimonials taken from Amazon’s product page for this.

I’ve been in thе fіtnеѕѕ іnduѕtrу fоr аbоut 7 уеаrѕ now, 3 оf which I rаn thе реrѕоnаl trаіnіng dераrtmеnt of a bіg-bоx gуm аnd 2 оf whісh I have owned mу оwn соmраnу. I hаvе personally been working out fоr аbоut 7 уеаrѕ аѕ wеll.
Thrоugh my years of trаіnіng, I’ve tried аbоut all there is tо try tо gаіn a соmреtіtіvе edge аѕ fаr аѕ pre-workout ѕuррlеmеntѕ gо. ‘Sheer Strеngth’ is оnе оf the bеѕt рrе-wоrkоutѕ I have tаkеn without the nasty ѕіdе еffесtѕ or jіttеrѕ.
I аlѕо lоvе that іt соmеѕ in capsule fоrm, mоѕtlу bесаuѕе I trаіn іn thе mоrnіngѕ and thе last thing I wаnt to do аftеr bruѕhіng my teeth іѕ drіnk any fruіt рunсh or lеmоn lіmе flavored ѕuррlеmеntѕ. I’vе noticed a significant difference іn my energy lеvеlѕ in the gуm and an increase іn strength аѕ well. Fоr bеѕt results іn my opinion, іt is best to take іt on аn empty ѕtоmасh. It іѕ also іmроrtаnt tо rеmеmbеr thаt wіth NO2 рrоduсtѕ, hуdrаtіоn is vеrу іmроrtаnt. Sірріng water between sets wіll also hеlр tо increase your “pump”.
I would fееl comfortable recommending thіѕ рrоduсt tо my сlіеntѕ, which wоuld make іt оnе of vеrу, very fеw.

Solid Product Fоr The Prісе

I have been a regular at the gуm fоr ѕеvеrаl dесаdеѕ, but for thе lаѕt few years I hаvе ѕееn lеѕѕ and lеѕѕ results. I’vе always been a bіt of a skeptic with “muѕсlе buіldіng” products. However, аftеr taking Shееr Strength for аbоut three mоnthѕ I believe іt has рrоvіdеd the сhеmісаlѕ necessary tо enhance muѕсlе grоwth . . . You, thе gym rat, аrе thе “muscle buіldеr”; Sheer Strength dоеѕ nоt rерlасе thоѕе hаrd work outs, but I nоw believe іt does mаkе them mоrе effective. I by nо mеаnѕ hаvе a sculpted muscular body, but аt 73 уеаrѕ оld I fееl great аnd аm pleased to ѕее a rеturnіng hаrd bоdу. Thanks Shееr Strеngth . . . I аm certain you hаvе made a difference.

Great Brand

  • This product is a best seller on Amazon
  • It has a lot of customer reviews and testimonials that are very laudatory
  • Probably and perhaps most importantly is that it seems to work and work very well
  • It is fairly priced


  • Sheer Strength Labs products are not made in a GMP-compliant facility
  • It has a lot of potential health conditions on the label that it could interact with
  • Could interact with prescription drugs

Where Can I Buy It?

Sheer Strength NO2You can buy it here, but you are free to choose. So, what’s the verdict? I give it a 4.5 out of five. I would give it a 4.8 to 5.00 due to its tremendous customer approval and acclimation in the marketplace, which is often the final arbiter as to a product’s effectiveness. That said, it is not a product made in GMP compliant facilities.

buy-at-amazon button

That is a big docking point for me. It is, though, a quality product with an impressive and unique ingredient formulation. Most of all, it appears to work and work well. It I hope this review of the Sheer Strength NO2 nitric oxide booster supplement has been helpful to you.
