DHEA is an endogenous steroid. It is the most abundant steroid in human beings. It acts on the androgen receptor directly and through its metabolites (androstenediol and androstenedione). These metabolities can undergo further conversion to produce the androgen testosterone and the estrogens estrone and estradiol. It is produced synthetically and used as a supplement because studies show that it can decrease cholesterol and other serum lipids. DHEA is used by muscle builders and athletes because it is believed to increase strength, lean body mass and testosterone levels, however, some researchers don’t agree with these claims.

Moomiyo is a herb found in Russian mountains which has been used by Russian athletes, soldiers and cosmonauts since a long time. Recently, it is gaining attention as a supplement for athletes and bodybuilders because research shows that it boosts immune system and enhances the metabolism of minerals needed for physical performance. Moomiyo is believed to increase muscle strength and shorten the recovery time after exercise. It does not contain any hormones but it is believed by Russian athletes that it helps in hormone disorders and also alleviates inflammation and joint pain. Moomiyo is commonly available in capsule form.

Tribulus Terrestris refers to an herb used in India and China as traditional medicines for centuries. Tribulus Terrestris contains active compounds known as steroidal saponins, and these are basically found in the leaf. The tribulus consists of furostanol and spirostanol glycosides. People use Tribulus Terrestris for erectile dysfunction as well as low libido. This has gained popularity owing to sports performance improvement. This is available in Russia and Bulgaria as it enhances the testosterone hormone levels, estrogen and DHEA. Tribulus Terrestris supplements taken for four weeks showed no effect on the hormones of the male sex. Preliminary studies heightened the sexual behavior in animals and yet the studies have not confirmed its effect on human beings. However, Tribulus is popular as an aid for sports performance as it shows no effect in exercise performance or body composition. Tribulus do not show any significant change in fat or body weight and this difference can be felt by experiencing strength in the leg press. Conversely, nursing or pregnant women should avoid taking Tribulus.

Vitamin E is the name for a group of tocopherols and tocotrienols that are soluble in fat and display antioxidant properties. The most important vitamin out of this group is alpha tocopherol, which professes the highest bioavailability, and therefore, was the most studied Vitamin E. Found in such foods as nuts, seeds, milk, wheat germ and most vegetable oils, this Vitamin is said to be perhaps the most important antioxidant in human nourishment, although this trait is not deemed the imperative reason why Vitamin E is required to be in every diet. Most clinical studies which were supposed to crown Vitamin E as the prevention from prostate cancer or cardiovascular wonder supplement have been either inconclusive or were discontinued due to poor results. Vitamin E deficiency results in neurological and neuromuscular problems, but also in failure to absorb fat.
