OTR-AC

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.

• Maximise muscle growth
• Increased bone density
• Greater strength and performance
• Improved recovery
• Leaner and drier look

OTR-AC Elite comes in 10mg capsules, with up to 3 capsules daily being the recommended dose. If you are using for the first time, or planning to stack OTR-AC with another SARM, we’d suggest using the lowest dose for this cycle and progressing dose upwards only when progress has absolutely stalled and biofeedback suggests you can.

The longest that it is suggested to run an OTR-AC cycle is 12 weken, with 8 weeks being perfect to reap the rewards. It is important to give your body adequate time to recover and for hormone levels to return to normal before embarking on your next cycle. Longer cycles might require longer off time, depending how successful your PCT was.
