MK-2866 Ostarine Liquid Solution — 25mg/mL

MK-2866 (Ostarine, Enobosarm) is an investigational selective androgen receptor modulator with an established research history spanning multiple Phase I and Phase II clinical trials investigating its effects on skeletal muscle and bone mineral density. As a research compound, MK-2866 functions as a selective androgen receptor agonist — binding to androgen receptors with high affinity and activating downstream anabolic signalling in muscle and bone tissue. Its non-steroidal structure and receptor selectivity profile distinguish it from classical androgens and make it a well-characterised tool compound in pharmacology and endocrinology research.

Format and specifications

This product is supplied as a liquid solution at a concentration of 25mg/mL. Available volumes: 30mL, 60mL, 90mL, 120mL, and 150mL. Solvent: pharmaceutical-grade polyethylene glycol 400 (PEG-400). Purity: ≥99% by HPLC. Concentration accuracy within ±5% of stated value. The 25mg/mL concentration offers higher compound density per volume compared to the 20mg/mL formulation, suitable for research applications requiring reduced solvent volume in assay preparation.

Purity and quality assurance

Every batch is independently tested by an accredited third-party analytical laboratory prior to release. Our protocol includes HPLC purity analysis confirming ≥99% purity and mass spectrometry identity confirmation verifying compound identity against reference standards. Buy Ostarine Australia conducts retesting independent of supplier documentation — all COA data reflects our own commissioned laboratory results.

Certificate of Analysis

The Certificate of Analysis for the current batch is available on our Lab Testing page. COAs are indexed by batch number and include purity result, analytical method, and laboratory accreditation details. Your order confirmation will include the corresponding batch reference. Documentation requests can be directed to support.

Storage

Store at room temperature (15–25°C) away from direct light and humidity. Do not freeze. Keep container sealed between uses. Shelf life is approximately 24 months under appropriate conditions. If crystallisation occurs at lower ambient temperatures, gentle warming will restore solution clarity without affecting compound integrity.
