OTR-AC (MK-2866 ESTER) SARM – 20MG/ML – 60ML BOTTLE

OTR-AC is a selective androgen receptor modulator (SARM) that is also commonly referred to as Ostarine-O-Acetate. This compound is an esterified version of the popular SARM, Ostarine, or MK-2866. While Ostarine and OTR-AC elicit similar benefits, the latter is considered to be the stronger of the two compounds following the esterification process.

Due to its ability to bind to androgen receptors, the SARM has been shown to mimic the action of testosterone. SARMs are becoming more popular and widely available for research purposes as evidence shows the compounds do not elicit negative androgenic side effects, like those observed with testosterone treatment.
