(2a, 3a-epiothio-17a-methyl-5a-androstan-17b-ol)

                 This exciting new compound originates from Japan and was originally used as an anti-estrogen agent in the treatment of breast cancer patients.  It also happens to be extremely anabolic with a low androgenic profile. 

                 This is the newest compound to hit the industry with low aromatization and no side effects.  It has a high oral bioavailability due to the 17a-methyl alkaloid and has a much higher myotrophic value then any other pro-hormone available at this time.
