OTR-AC, also referred to as Ostarine-O-Acetate, is a selective androgen receptor modulator (SARM) that is an esterified version of the popular compound, Ostarine. The benefits of OTR-AC and Ostarine are very similar, however, OTR-AC is considered to be the more effective compound following the esterification process.

SARMs have been shown to mimic the action of testosterone by effectively binding to androgen receptors. These compounds are becoming more popular and widely available for research purposes as evidence shows SARMs do not elicit negative androgenic side effects, such as increased prostate weight, that are typically associated with testosterone treatment.



How does Ostarine MK-2866 work?

Ostarine works by selectively binding to androgen receptors in the body, primarily in muscle and bone tissue. This selective binding triggers anabolic effects, leading to increased muscle mass, improved strength, and enhanced bone density.

Can I stack Ostarine MK-2866 with other SARMs?

Yes! Ostarine MK2866 is commonly stacked with other performance-enhancing compounds to potentially amplify its effects.

How should I dose Ostarine MK-2866?

Commonly recommended doses are between 2 capsules or 1ml for full dosage with cycles generally extending 12+ weeks.

Should I PCT?

Yes, we always recommend a PCT after each cycle. Here are two of our favorites below!
