There are 2 main reasons guys turn to natural testosterone boosters. Either they’re trying to halt the T loss that comes with age and reclaim their prime, or they’re trying to safely achieve the max hormone their system can produce to dominate in the gym.

If that second category is you, you might be tempted by a name like Supremacy 2.0.

Supremacy 2.0

It’s not just the name that draws you in either. Makers Neogenix not only claim it will boost energy, strength and libido, but also that users will put on 1lb of muscle a week! Now maybe we’ve been in the supplement game to long but we’re very cynical about that.

What do they think we were BOURNE yesterday?

One thing we’re supremely pleased about is that there’s no proprietary blends here, which is perfect. That means we can see all the ingredients and their dosages. Sounds like a no-brainer, doesn’t it, but you’d be suprised how many companies are still happy to keep customers out the loop.

How Does It Work?

At a Glance

  • Vitamin D3 to boost T levels
  • Vitamin B6 and Indole-3-Carbinol to limit estrogen
  • Zinc to support healthy T creation
  • Eurycoma Longfolia to stimulate libido
  • Momordia Charantia alledgedly to further help male hormone

Looks pretty strong at a glance but the detail’s where it really matters. We’ll look closer after the scores.

The Scores

Supremacy 2.0

Apart from the vitamin B6 which has a solid amount even some of the high points of Supremacy 2.0 aren’t as good as they look.

Vitamin D3 can really kick start your test but only at a minimum of double what you’re getting here and likewise the zinc could be safely quadrupled. Eurycoma Longfolia may help libido but not much else, Coleus Forskohli has shown some promise but is unreliable.

Momordia Charantia is not only inproven but could cause side effects.


You can pick Supremacy 2.0 up for just over $40. That’s not bad in the grand scale of T boosters but considering some of Supremacy 2.0’s issues, it’s probably $40 better saved and spent on a more impressive brand.


No proprietary blends is always the sign of a confident formula, but we wouldn’t give this one a perfect score on the strength of just that.

There are problems here. About the claims being made with some ingredients and the dosages of others. Any time you have an component that may cause side effects (even if uunlikely) it pays to be wary.


Generally Supremacy 2.0 gets strong reviews on retail sites where it’s sold, but there is enough negative feedback (no results) to plant the seed of doubt in your mind. What would clear this up straight away is the kid of detail and indepth personal user stories you get in a testimonal section on the official site, but there are none.


The Neogenix website is professional and slick enough looking, but there’s not a lot of company background info. It’s mainly just their general mission statement and material about the handful of products they currently sell. These include Body Forge Ultra, Velocity Ultra and Velocity 3.0. Judging from the feedback we’ve seen, there’s no reason to believe the company is suspect, it’s just your policy should always be the more disclosure the better.

How Do I Take It?

Users are told to take one capsule 3 times a day 15 minutes before meals. They should take Supremacy 2.0 for 12 weeks then have a 2 week rest.

This is not bad. 3 servings evenly spaced out will keep what active ingredients firing through most of the day. Personally we would throw another serving in there for luck, but 3 is a lot better than some boosters try to get away with.

Any Supremacy 2.0 Side Effects?

Though it’s unlikely in such a small dose the side effects of Momordia Charantia are potentially very serious and should be noted.

These include vaginal bleeding in women and liver toxicity, diarrhea and vomiting, chest pain in both genders.

Where Can I Get It?

Supemacy 2.0 is available from Bodybuilding.com for around $42. This gets you a month’s supply of 60 capsules.

Ingredients – In Detail


Vitamin D3

Called the sunshine vitamin because it is created when sunlight hits our skin, levels of vitamin D are directly linked to the amount of testosterone we produce. That’s why male hormone tends to spike during summer.

You can’t always rely on good weather so supplementing is useful. The problem is only doses of around 3000IUs has an effect and Supremacy 2.0 only offers 1500IUs.




Zinc is vital for the building blocks of testosterone like luteinizing hormone, human growth hormone and follicle stimulating hormone.

A high percentage of guys with low testosterone are also lacking in zinc so it’s worth keeping yourself topped up. Most people’s daily tolerance is 30mg, which makes just 7.5mg per serving a bit low.


Vitamin B6

Estrogen is at the other end of the hormonal balance to T ao when one is up the other is down. B6 is useful because it lowers the production of the female hormone and reduces the effect of what’s already in the system. Supremacy 2.o’s dose is a solid one.


Eurycoma Longifolia

Sometimes called Longjack this herb’s real strength is as a consistent libido booster. Certain studies have shown that it may return men suffering with clinically low testosterone back to within normal range, but this is disputed and sex drive improvement is the only solidly proven benefit.



When digested, usually in green leafy veg, this becomes the nutrient DIM. DIM is used in boosters because it has shown an ability to limit estrogen in some studies. Importantly though other research has shown it certain amountsit can actually raise the female hormone. We’re always wary of it for this reason.


Momordica Charantia

This sub-tropical vine has shown an ability to help T in limited studies but it needs more work and the potential for side effects, at least at this stage, is hardly worth it.


Coleus Forskohlii

Coleus Forskohlii shows some ability to boost T, but the increase is only slight and wasn’t consistent across the whole subject group. Not really dependable enough to be one of our top choices for a booster.


Anything Missing?

D-Aspartic Acid is a cornerstone of all the best boosters on the market so it’s a shame not to see it here. Magnesium is also great for raising your free T levels and that would’ve strengthened recipe. Boron is also useful as it both lowers estrogen and raises T.


Supremacy 2.0 looks more promising than it actually when you look at the details. There are a few positives, enough to make us think by Supremacy, ohhh let’s say 7.0, they might be challenging the best boosters. But right now its got a long way to go.
