Ostarine (MK-2866) – Powder, 1g

Ostarine (MK-2866) – Powder, 1g

This premium, laboratory-grade research compound delivers ultra-pure raw Ostarine (MK-2866) powder at ≥98% purity, representing the highest standard for modern scientific investigations into selective androgen receptor modulation and anabolic signaling mechanisms in muscle and bone. The lyophilized crystalline powder form provides investigators with a single-compound reference standard ideal for analytical testing, in vitro cell culture modeling of AR-mediated pathways, and in vivo preclinical research applications where precise Ostarine isolation is critical for studying muscle wasting prevention, bone density enhancement, and tissue-selective androgenic effects. MK-2866 shows a marked preference for the androgen receptor in skeletal muscle and bone, while treading lightly on the prostate and sebaceous glands, demonstrating superior tissue selectivity compared to conventional androgens.

Technical Specifications & Chemical Profile

Research Applications & Storage Protocols

SARM-Mediated AR Agonism & Muscle/Bone Enhancement Profiling

MK-2866 (also known as Ostarine, Enobosarm, and GTx-024) functions as a selective androgen receptor modulator (SARM) and is the first-in-class SARM, representing a potent, non-steroidal tissue-selective androgen receptor agonist developed by GTx, Inc.. The compound is a nonsteroidal SARM that selectively targets androgen receptors in the body, predominantly in muscle and bone tissues, with a marked preference for the androgen receptor in skeletal muscle and bone, while treading lightly on the prostate and sebaceous glands, demonstrating superior tissue selectivity. MK-2866 has high affinity for the androgen receptor with a Ki of 11 nM, making it a potent AR agonist for research applications. In clinical trials, Ostarine has been demonstrated to increase lean body mass, improve physical function, and enhance muscle strength without significant androgenic side effects, confirming its therapeutic potential for muscle wasting conditions. The half-life of MK-2866 is approximately 24 hours, and most clinical studies have used once-a-day dosing protocols, supporting convenient dosing for research applications. Ostarine selectively targets androgen receptors in muscle and bone tissues, with its capacity for muscle enhancement, improved restoration, and overall performance optimization validated for efficacy. MK-2866 is used to combat muscle wasting and osteoporosis, demonstrating its therapeutic applications for age-related and disease-related muscle loss. Ostarine for sale selectively targets androgen receptors in muscle and bone tissues, demonstrating tissue-selective activation of androgenic signaling. This SARM mechanism positions Ostarine as a critical tool compound for investigating muscle wasting prevention research, osteoporosis treatment models, lean body mass preservation studies, bone mineral density enhancement pathways, sarcopenia reversal mechanisms, cancer cachexia treatment, intermittent hypoxia-related muscle loss, and tissue-selective androgen receptor signaling in preclinical models, offering potential therapeutic insights for metabolic and musculoskeletal disorders. Ostarine is banned in sport and is on the World Anti-Doping Agency Prohibited List, detectable in urine for several weeks, confirming its performance-enhancing properties.

Handling & Storage Guidelines

• Long-Term Storage: Store at -20°C (-4°F) for optimal stability (up to 3 years); stable at room temperature for short-term storage. Minimize open air exposure; store in a cool, dry place in airtight conditions away from direct sunlight to maximize shelf life; protect from light and moisture; double-sealed Mylar bag or PET single-wall jar provides moisture barrier and UV resistance

• Solubility: DMSO: 70 mg/mL; Ethanol: 70 mg/mL; ethanol: 25 mg/mL; DMSO & DMF: 15 mg/mL; solubility varies by solvent; prepare fresh solutions immediately before use; aqueous solutions have limited solubility

• Appearance: White to off-white powder; melting point 70-74°C; clear solutions in DMSO, ethanol, and DMF when properly dissolved
