OTR-AC (MK-2866 ESTER) SARM POWDER – 1000MG / 1 GRAM

OTR-AC is an advanced, esterified modification of the foundational SARM MK-2866 (Ostarine). Isolated as a raw crystalline powder with a certified chemical purity of $\ge$99% via rigorous LC-MS testing, it ensures exceptional molecular stability for controlled laboratory configurations. The addition of the ester group extends the compound's active half-life, allowing for a sustained, progressive binding affinity to selective androgen receptors within bone and skeletal muscle tissue. In structural research models, OTR-AC powder is highly investigated for its capacity to maximize prolonged protein synthesis, accelerate dense lean mass accretion, and facilitate bone mineral restoration without the plasma spikes typical of non-esterified compounds.
