D-Aspartic Acid by Infinite Labs Nutrient Profile

D-Aspartic Acid (3 g) operates to help regulate testosterone synthesis, and according to researchers, this ingredient has shown a remarkable ability to promote fertility, and even better, enhance testosterone.

Testosterone enhancement from this ingredient can take as little as 12 days, especially in infertile men. On a negative note, the effects of D aspartic acid on testosterone appear to be extremely short lived, as levels can return to where they were before supplementation in as little as four weeks.

Just to illustrate how powerful this ingredient is in terms of testosterone enhancement, this study involving 43 male subjects, who were supplemented with 3 g of D aspartic acid daily, with meals over the course of 12 days, noticed impressive increases in testosterone and luteinizing hormone synthesis.

An altogether different study involving 60 infertile men who were supplemented with 2.66 g of D aspartic acid daily saw average increases of up to 60% in their testosterone levels.


D aspartic acid as an ingredient has repeatedly demonstrated formidable testosterone enhancing properties, as well as possessing pro-fertility and aphrodisiac effects.

In my opinion, relying solely on D aspartic acid as an ingredient to increase testosterone certainly has its limits because without accompanying ingredients such as fenugreek, and zinc, for testosterone enhancement to be sustained, long-term use is required otherwise levels will fall back down to where they were prior to supplementation.

This essentially means more cost in the long run.

D-Aspartic Acid by Infinite Labs Overall Rating

This is definitely a high quality supplement, but the only downside is it solely relies on one ingredient. Although it is adequately doors as per studies, it requires long-term use for effects to remain.

Without accompanying testosterone enhancing ingredients like zinc and fenugreek, D-Aspartic Acid by Infinite Labs is certainly limited in its scope.
