Ostarine (MK-2866)

What is Ostarine (MK-2866)?

Ostarine, also called MK-2866 or Enobosarm, is a SARM. SARM stands for selective androgen receptor modulator, a lab compound.

Studies note it has a half-life of about 24 hours. Half-life means the time it takes for half a dose to leave the body.

It comes as a tablet, made in a lab for research use only.

What researchers study it for

• Muscle tissue. Researchers study how it binds to androgen receptors in muscle tissue.
• Bone tissue. Studies also look at androgen receptors found in bone tissue.
• Strength and recovery. Labs track strength and recovery measures in trial settings.
• Fat and muscle balance. Researchers study fat loss alongside muscle tissue changes.
• Hormone levels. Studies also track changes in natural hormone levels during test periods.

What you get

One bottle of 90 tablets. Each tablet holds 10 mg of ostarine.

How to store it

Keep the bottle in a cool, dry place, out of direct sunlight.
