Clinically proven by the University of Memphis to raise testosterone and nitric oxide levels.

D-Pol was specifically formulated to help raise your natural free testosterone levels through a clinically proven combination of amino acids and vitamins. 3.12g of D-Aspartic Acid (DAA) works in conjunction with the powerhouses Vitamin D, NO3-T and B vitamins to provide a natural, gradual increase in free testosterone along with an increase luteinizing hormone(which helps to improve your reproductive system functionality). Additionally, D-Pol helps to increase nitric oxide production causing a prolonged spike in blood and oxygen delivery. D-Pol is also known to create an oxygen sparing environment by increasing aerobic efficiency and to increase ATP production generating a greater power output.

D-Pol powder nutrition panel

D- Aspartic Acid
D-Aspartic Acid (DAA) is an amino acid that plays a role in creating and releasing hormones within the body. DAA is especially popular for its testosterone building capabilities. Studies show that individuals taking DAA had higher circulating luteinizing hormone levels and higher levels of free testosterone after 12 days of use.

B Vitamins
B vitamins work great in conjunction with DAA to help to elevate circulating free testosterone.

...Specifically our NO3-T. Studies show that nitrate supplementation allows exercise to be tolerated for a greater period of time - which may translate into more repetitions being performed during a given set of exercise and/or a greater load to be used during each set of exercise.

Vitamin D
As a hormone regulating more than 1000 vitamin D-responsive human genes, vitamin D may influence athletic performance. Studies show that healthy men who supplemented with 3332 IU of vitamin D daily for one year, noted a significant increase in total, bioactive, and free testosterone levels. For optimal vitamin D absorption, taking vitamin D with the largest meal of the day seems most appropriate.


Take 1 serving of D-Pol first thing in the morning with breakfast on both exercise and non-exercise day. OR, take 1 serving of D-Pol pre-workout with a snack.

This is one of my favorite products. I’ve been taking this for a few years all the way back when it was custard cream. It has a great taste and effects for such an affordable price. I would recommend taking this product with your pre workout especially since it has extra nitrates and then on your off day first thing.
