Osterine, also known as MK-2866, is a type of SARM that’s increasingly used by bodybuilders for muscle retention and fat loss. Although it was originally developed for muscle wasting diseases, its muscle-preserving effects have made it a popular choice in the sports nutrition community.

Unlike traditional anabolic steroids, Ostarine selectively targets androgen receptors without extreme androgenic side effects. This makes it as a safer alternative, especially for those looking for improved physique results without harsh post-cycle damage. Still, understanding the proper **ostarine dosage**, half-life, and potential **side effects** is essential for safe and effective use.

Recommended Dosage of Ostarine

The standard dosage for MK-2866 ranges from 10 to 30 mg daily, depending on the user’s goals and tolerance. For first-time users, a daily dose of 10–15mg is usually sufficient for seeing lean gains without heavy suppression. Experienced users may raise the dose slightly, but exceeding 30mg daily is not recommended due to the risk of test suppression.

Ostarine Half-Life Explained

Ostarine has a relatively long **half-life of approximately 24 hours**, meaning only one dose per day is usually enough to keep stable blood levels. This also makes it convenient for users who like once-a-day supplementation routines. If you're stacking with other SARMs or compounds, it’s still best to monitor your dosing windows to minimize interactions.

Ostarine Side Effects

Despite being non-steroidal, Ostarine is not without side effects. Reported side effects ostarine dosage include lowered natural testosterone levels, fatigue, and joint pain in some users. In rare cases, individuals may experience acne, or mood shifts, especially at excessive doses or longer cycles. These side effects often resolve post-cycle, but it’s wise to follow with a mild post cycle therapy protocol if needed.

Female users may also use Osterine at lower doses (5–10mg/day), though virilization risk is significantly lower than with traditional anabolics.

MK-2866 is often used for:

- Cutting phases
