OTR-AC, also called MK-2866 Ester, is MK-2866 (Ostarine) which has undergone esterification during chemical synthesis to maximise potency, biodistribution and half-life. The esterification of anabolic agents results in at least a 10-fold increase in half-life, which means that the active ingredient has the potential to remain bioactive ten times longer. This results in numerous benefits, such as decreased dosing frequency and more stable blood levels.
In coming years, it is possible that OTR-AC might replace many Ostarine products on the market, due to the differences explained above which appeal to many users.
