Testosterone Booster GNC : We look at their 5 best sellers

Best selling test boosters on the GNC website

LAST UPDATED: January 2019.

Author: Ben has been trialing and testing supplements for over a decade, this has lead to a lot of hours analyzing and researching nutrients.

After a few years he wanted to provide a free resource to offer his findings for anyone who would be interested in understanding what they are using.

Otherwise, Ben plays rugby, is a Army Reserve soldier, likes cycling, skiing and hitting the gym. He graduated from university in 2005 with a bachelors degree.

Biggest Sellers

When looking for a testosterone booster or anything you like, convenience for many is king. And websites such as that developed by GNC are here to make life easier for us.

Personally, I now very rarely buy anything from a shop, not even cars.

I prefer buying online, in fact I have just bought a very cheap and rare Mazda Xedos…exactly, you’d never heard of it either.

However, I like online shopping because I prefer not to be hassled.

I would much rather be able to look through the details in the comfort of my own home with no one closely monitoring me or trying to close me on a deal.

I don’t like the ‘advice’ that comes from shop assistants, either.

I ask myself why I would bother heading over to a local supplement store to read through tons of ingredients on loads of bottles?

Not when I can do the research for products at my desk and slowly analyse comparative products and ingredients with a fine toothed comb.

This way I can make an informed decision in good time and under no pressure. I can also do a quick price comparison to find the best retailers.

With this in mind, one of the first stops for anyone in the market for supplements is Amazon, Walgreen, Walmart or even GNC.

TL:DR – Video Review of the Best Selling Testosterone Boosters on GNC


GNC are a global entity with their span far and wide, this is great if you do actually want to hit a bricks and mortar store.

But with it should come some sense of value and trust.

Online retailers and especially those with a bricks and mortar presence offer a wide and expansive range of supplements for every need, niche and aspiration.

GNC being no different.

When looking for products on retailer websites you can often search or filter by the best selling products.

In some cases, it is tempting to go down the popular route, and why wouldn’t you?

Lot’s of people buy Toyota Camry’s, for good reason, too. They’re reliable, safe and economical.

With that in mind, why wouldn’t we head down the same route for supplements?

Well, you can, however, people tend to buy based on the look of a product rather than what’s actually in it.

Or they will buy purely based on brand names.


Over the early 2000’s, Mercedes really hit a low point for reliability and quality, but people bought the trusted brand all the same when there were much better offerings available.

If someone is new to a product or niche it can be overwhelming and confusing.

Naturally, once you recognise a brand name you are instantly drawn towards it, regardless of what it contains and you could end up buying a dud.

But there’s so many more products out there, so what do you do?

However, the problem with these sort of online ‘marketplace’ type sites like Amazon is that nearly any one can start selling products on there with little screening or quality control to the unsuspecting public.

Plus, there’s often lots of spam to filter through.

However, a company as well respected as GNC not only sell other brands’ products, but even produce and sell their own.

So, I wanted to find out just how good or not the best selling testosterone booster products available to buy from GNC really are.

Check out these best selling testosterone boosters available to buy from GNC

Nugenix Free Testosterone Booster

This test booster should contain a number of proven ingredients to stimulate an increase of natural testosterone.

However, there’s a few problems with this.

There’s a low overall daily dose, and it also partly consists of a proprietary blend.


  • Contains the ingredients found in a ZMA
  • Fenugreek also present as found in the best T-boosters


  • The ZMA aspect is very under dosed
  • Proprietary blend
  • Contains Tribulus
  • No idea of product origin

Nugenix Ultimate Testosterone Booster 

Looking very similar to the Free test booster offered by Nugenix you may have thought the performance would be similar too,

However, you would be wrong, this offers a better ingredient profile that can help towards reaching your lifting or just general health goals. It isn’t without fault, though.


  • Contains DAA at the correct required dose to be effective
  • A further three ingredients can help increase test levels
  • Effective doses


  • Three ingredients offer no proven benefit
  • Expensive
  • Still omits other needed ingredients

Nugenix MAXX Testosterone Booster


Nugenix are really cleaning up in the popularity stakes on the GNC website it seems.

This includes some great test boosting ingredients, but it would seem, for MAX benefit we would require to supplement all of the three Nugenix T boosters to really have maximum impact on our test levels.

Although it proclaims to be a MAX supplement, it does lack other proven ingredients found in some better test boosters, it even lacks the DAA found inits sister product which seems like a missed opportunity.

While this is good, it is also a missed opportunity due to the doses of each ingredient.


  • Contains five effective and proven ingredients
  • Estrogen regulator included


  • Prohibitively expensive
  • Tribulus is present
  • Less than 50% of the ingredient profile is proven to be effective

Cellucor P6 Ultimate Testosterone Booster

This is a premium looking and costing supplement. At over $150 this is up there with some of the most expensive T-boosters.

For that price we want more than just nice looking packaging.

This does contain a lot of ingredients which offers a lot of confidence and a reason behind the high price tag.

However, this also consists of a proprietary blend so even though there’s a lot of ingredients listed, the amounts included could be minimal.


  • Two test stimulating ingredients
  • Two estrogen regulator ingredients
  • An anti-inflammatory ingredient
  • Five pills and over 3000mg daily dose


  • Proprietary blend
  • Omits lots of other proven test boosting ingredients
  • High price

Novex Biotech Growth Factor 9

This supplement would have you believe that it will increase human growth hormone production.

The packaging looks great and it is reassuringly expensive to buy, so what could possibly go wrong?

Well, a lot it could seem…there’s plenty of issues with this and it is not going to give you big muscles.


  • May help increase blood flow
  • Includes an anti-inflammatory
  • Could help with liver health


  • Proprietary blend
  • Low overall daily dose
  • Nothing to increase growth hormone
  • Under dosed for certain ingredients to be effective
  • Expensive for what it is
