Epistane (Epi) is a DHT derivative that is similar to epitiostanol - a Japanese anti-estrogen drug used to treat breast cancer. The difference is that epistane has an additional single methyl group, which helps it give a much stronger anabolic release. As a matter of fact, on paper it has a 1100:91 anabolic to androgenic rating. Thanks to its DHT structure, Epi will not aromatize into estrogen like other prohormones or steroids raw powder will.

What's more, epistane does not present progesterone issues, which happened with most pro-hormones that were sold over the counter during the "PH Boom" era. Therefore, epistane will not cause rebound gyno or other related side effects. Thus, it is best ran by those looking for dry gains and as a 'cutter' before a contest or photo sessions.

Epistane, exhibits a strong, long lasting anti-estrogen effect that is organ tissue specific. This means it works only where you want it to work. Broad range estrogen blockers and aromatase inhibitors can result in system shut down, aching joints, and decreased I'GF-I expression. Epistane binds specifically to the 17-estradiol receptor protein in the target tissues. Because of its long lasting and strong effects on specific tissue, Epistane can significantly reduce and reverse the effects of gynocomastia because not only does Epistane specifically block estrogen in breast tissue but it induces an estrogen-depleted condition which leads to apoptosis or the death of the breast tissue cells. Studies show that small doses of the parent compound, Epitiostanol, at just 10-20mg/week showed a complete disappearance of the mass and pain in 25% of the male patients in the clinical trail, while the other 75% of the patients showed at least a 50% reduction in the mass and complete loss of pain in just 4-8 weeks. Thats results in 100% of the male users with no side effects.

Epistane is more than an anti-estrogen, though, as it also binds to androgen receptors in skeletal muscle. As a PRO-Anabolic compound Epistane promotes increases in strength and lean body mass with an anabolic/androgenic value (Q ratio) of 12. With most powerful androgens there is a high risk of the natural suppression of the gonads. Epistane, unlike other PRO-Anabolic compounds that have recently been released, is relatively mild on the gonads and, due to the anti-estrogenic effects and the fact that Epistane keeps LH levels elevated, post cycle therapy becomes a breeze. All effects combined make Epistane a great compound to produce dry, lean gains in muscle mass with minimal side effects and suppression of the bodys natural androgen production, while lowering the effects of natural estrogen or combating estrogen from endogenous/exogenous sources. This makes it a powerful tool when combined with wet compounds in attempt to increase gains and decrease side effects. One can also not overlook the potential benefit of this compound taken alone, especially when recovering from periods of wet compounds.
