The reasons for using a test booster are simple. Increased athletic performance, muscle gain, fat loss, libido, a veritable laundry list of desirable masculine traits. Now if only it were so simple to find one that works…

I’m sure I’m not alone in seeming to have tried virtually every ingredient or product claimed to boost testosterone, from A to Z. I’ve lost count of those that did nothing, but some really do work!

And from those, I’ve narrowed it to the top 3…the pick of the litter. I’ve reviewed them below and more than that, I got myself tested and ranked them by 30 day before and after testosterone level BLOODWORK.

Core Nutritionals Core ALPHA

Core Test

Core Nutritionals has produced the best standalone testosterone booster on the market. Core ALPHA takes the products that gave me the best bloodwork and results, D-Aspartic Acid and Erase, includes a full dose of them and adds a few ingredients to take that unbeatable combination to the next level. The result? 48% testosterone increase in 30 days!!!

Ingredients/Mechanism of Action:

From my D-Aspartic Acid and PES Erase review:

D-Aspartic Acid (DAA) is an amino acid that has been building some serious momentum in the supplement industry. It increases luteinizing hormone, which directly signals the testes to produce more testosterone. The numbers backing that science are there…it has independent lab studies on humans (not rats or some other lab animal) and user reports from those like myself showing significantly elevated testosterone levels.

When your testosterone levels are raised, which DAA WILL clearly do, estrogen levels also rise in the body as a result. High estrogen will seriously hamper many of the benefits of elevated testosterone such as improved body composition and athletic performance. DAA in particular is known for producing large estrogen increases…and that’s where Erase comes in. Erase is designed to stop your body from producing excess estrogen, while not impacting the testosterone increases from the D-Aspartic Acid.

Here is where Core ALPHA gets clever, with the introduction of Coleus forskohlii (extracted for 20% Forskolin). What Forskolin does is increase cAMP, a messenger of the endocrine system. Why is this important? The chief limiting factors in testosterone production are luteinizing hormone (LH) and available cholesterol. Firstly, increasing cAMP levels stimulates a protein called StAR, which improves the transfer of cholesterol, thereby making the testosterone production process more efficient. Secondly, it up-regulates luteinizing hormone, effectively making the stimulation of luteinizing hormone by DAA all that much more potent. And as a welcome bonus, those increased cAMP levels increase lipolysis (fat burning), providing increased energy and the potential for fat loss, especially if being used in a caloric deficit diet.

Core ALPHA includes another aromatase inhibitor, Brassaiopsis Glomerulata, on top of Erase to further support estrogen balance. Mucuna Pruriens (L-DOPA), is also added to counter potential increases in prolactin, which like estrogen, can affect some when using DAA. 

Core ALPHA also includes the all-around powerhouse vitamin D. Healthy vitamin D levels have been correlated with virtually every conceivable health marker you can think of. It is also one of the most commonly deficient nutrients, even amongst those who have it included in their multivitamins, which rarely include enough of it. As you can imagine, correcting this deficiency has numerous advantages, as evidenced by studies showing vitamin D supplementation to increase testosterone levels (as well as increase fat loss). Lastly, the product has zinc, yet another commonly deficient vitamin and one that can have a dramatic impact on testosterone levels as well.

D-Aspartic Acid (DAA) and PES Erase

D-Aspartic Acid and PES Erase

OK, yeah, I’m technically cheating by using 2 products together (even though each product has just one ingredient). But the synergy is unbeatable and together they still cost less or the same as any top standalone testosterone booster. And with a 43% testosterone increase in 30 days…the results speak for themselves.

Ingredients/Mechanism of Action:

D-Aspartic Acid (DAA) is an amino acid that has been building some serious momentum in the supplement industry. It increases luteinizing hormone, which directly signals the testes to produce more testosterone. The numbers backing that science are there…it has independent lab studies on humans (not rats or some other lab animal) and user reports from those like myself showing significantly elevated testosterone levels. You feel it too, my workout and sport performance increases were on enough of a higher level for people to ask what I was taking. Oh yeah, and it costs a paltry $13 for a month’s supply, that bang for the buck simply can’t be beat. However…

When your testosterone levels are raised, which DAA WILL clearly do, estrogen levels also rise in the body as a result. High estrogen will seriously hamper many of the benefits of elevated testosterone such as improved body composition and athletic performance. DAA in particular is known for producing large estrogen increases…and that’s where PES Erase comes in. PES Erase is designed to stop your body from producing excess estrogen, while not impacting the testosterone increases from the D-Aspartic Acid.

Driven Sports Activate Xtreme

Activate Xtreme

Driven Sports formulas always look well thought out on paper. Activate Xtreme (AX) is no exception, it boasts a number of proven testosterone boosting ingredients. More than that, the formula goes the extra mile and includes an anti-estrogen to boot. And it showed in the bloodwork, with a more than respectable 30-day 34% testosterone increase and an estrogen level still within normal range.

Ingredients/Mechanism of Action:

Two of AX’s ingredients, Mucuna Pruriens and Bryonia Laciniosa, work to increase luteinizing hormone (LH), which signals the testes to produce more testosterone. The LH increase is not as large as the one you experience with D-Aspartic Acid, but it still does the job of significantly increasing testosterone levels. They also provide other benefits, such as inhibiting prolactin and regulating the rate-limiting protein stAR, potentially further increasing testosterone levels. Divanil is a nettle extract that decreases the binder SHBG, which allows more of that created testosterone to be freed to circulate through the body. Cholecalciferol, or vitamin D3, is a common nutrient deficiency, that, when corrected, can provide a large increase in testosterone levels in addition to other health benefits. Maca root is included because it is a potent adaptogen, which means it helps ensure optimal function of biological processes such as testosterone production, fighting off stressors such as cortisol.

Lastly, PZole, a proprietary extract, is included as potent anti-estrogen to counter the increase in estrogen that occurs when testosterone levels are raised.
