MK-2866 (Ostarine)

MK-2866, commonly known as Ostarine, is one of the most researched and widely used Selective Androgen Receptor Modulators (SARMs). Originally developed by GTx Inc., Ostarine was intended for the treatment of muscle wasting diseases, osteoporosis, and age-related muscle loss.

Today, MK-2866 is one of the most trusted SARMs in the research community due to its ability to support lean muscle growth, enhance strength, preserve muscle during calorie deficits, and improve bone density.

What is MK-2866 (Ostarine)?

MK-2866 is a non-steroidal oral SARM that selectively binds to androgen receptors in muscle and bone tissue. Unlike anabolic steroids, it does not convert to estrogen or DHT, reducing the risk of hormonal side effects.

Researchers value Ostarine because of its mild profile, making it one of the safest SARMs for studies in both bulking and cutting phases.

Potential Research Applications

• Treatment of muscle wasting diseases

• Support in osteoporosis studies

• Research into age-related muscle loss (sarcopenia)

• Rehabilitation and recovery trials

Possible Side Effects

Although Ostarine is regarded as a mild SARM, researchers have reported potential side effects:

• Mild testosterone suppression (dose-dependent)

• Temporary fatigue or nausea

• Slight changes in cholesterol levels

• Rare water retention

⚠️ Side effects are usually milder compared to steroids and often reversible after discontinuation.
