Ostarine MK-2866, also known as enobosarm, is the most clinically studied selective androgen receptor modulator (SARM). Vi Corpus supplies it as VASCULAR, a research solution for Australian laboratories investigating muscle and bone biology.
Key research features of Ostarine MK-2866
- Extensive trial history. Enobosarm has been tested in human studies of cancer-related muscle wasting.
- Tissue-selective action. It targets androgen receptors in muscle and bone more than in other tissues.
- Nonsteroidal. It does not aromatise to oestrogen or convert to DHT.
- Common reference SARM. Many studies use it as a baseline when comparing newer SARMs.
- Third-party tested. Batch reports are available through our Lab Tests page.

Research applications
GTx Inc. developed enobosarm, and phase 2 trials reported gains in lean body mass in older adults and in people with cancer cachexia. Later studies explored stress urinary incontinence and breast cancer. As a result, Ostarine has more published human data than any other SARM. Labs often study it alongside RAD 140 or in our SARMs stacks.

Frequently asked questions
Is Ostarine the same as enobosarm?
Yes. Ostarine, MK-2866 and enobosarm are names for the same compound.
Is Ostarine approved for human use?
No. It has not been approved by the TGA or the FDA, so we sell it for laboratory research only.
How should the solution be stored?
Keep the bottle tightly sealed and away from heat and light. Room temperature storage in a dark cupboard is suitable for most labs, although a fridge extends shelf life.
