EPISTANE-One of a number of steroidal compounds researched in the 60s by Searle Laboratories, while it was never used clinically in the West, the unmethylated analog epitiostanol has been used to treat breast cancer and gynecomastia in Japan.
The two first “prohormone” products containing this compound, IBE’s Epistane and RPN’s Havoc, are still the two best-selling “epi” products on the market.
Epistane is a methylated version of the controlled substance Epitiostanol (2Â±,3Â±-Epithio-5Â±-androstan-17Â²-ol), created in the 1960’s and used as a treatment for breast cancer. Chemists added a methyl group to the compound to create the product known as Epistane. Epistane is a sulfur containing steroid which is known to have strong and long lasting anti-estrogenic activity as well as weak androgenic and mytropic activities.
Since it is anti-estrogenic, you can expect very dry gains from this compound. Epistane has low androgenic to anabolic activity, meaning it is much more anabolic then androgenic. Even though users will see dry gains on Epistane it does not mean that it would be any insufficient for a bulking cycle.
