Methyl-1-testosterone is the methylated version of the steroid 1-testosterone. It is a DHT derivative. It cannot convert to DHT or estrogen. M1T is 910-1600% as anabolic and 100-200% as androgenic as methlytest. There is a structural modification that allows the compound to survive the first pass through the liver. This is what makes it extremely orally bioavailable but also liver toxic There are were literally hundreds of different anabolic agents that were being actively studied and pursued by drug companies. M1T had a very favorable ratio of anabolic to androgenic effect, so there was much promise with this compound.
