Ostarin MK2866

Ostarine is a selective androgen receptor modulator (SARM), taken orally, that binds to androgen receptors mainly in muscle and bone rather than acting on the whole body the way a steroid does. It is commonly used to help preserve lean tissue during a calorie deficit and to support a mild recomposition effect. It is generally regarded as one of the mildest SARMs, which is why it is often used as a first entry point into SARM protocols. This is a guide, not medical advice, so speak to a doctor before starting.

As a general guide and not medical advice, a common approach is one 10mg capsule daily for the first two weeks, then two 10mg capsules (20mg) daily for the remaining stretch of an 8 week run, taken at the same time each day with food. Some do not go higher than 25mg per day. Individual response varies, so start conservatively and speak with a doctor before beginning any compound.

Yes, Ostarine causes some testosterone suppression even though it is milder than most other SARMs, so a PCT is still recommended. A common protocol reported by users is nolvadex (tamoxifen) at 20mg daily for 4 weeks, starting around 2 days after the last capsule, with no taper needed. Baseline and follow-up bloodwork covering testosterone, oestradiol, LH, FSH and a lipid and liver panel is the sensible way to track how your own body responds.

Commonly reported side effects include mild testosterone suppression, possible joint discomfort, mild headache or nausea in the first week, and hair shedding in those already predisposed to it. Liver enzyme markers can also rise slightly, which is why many pair a cycle with a liver support product such as N2Guard. This is general feedback, not a clinical guarantee, so bloodwork is the best way to monitor your own markers.

Ostarine on its own is aimed at lean tissue retention and mild recomposition. Cardarine (GW-501516) is a PPAR-delta agonist rather than a SARM, and works through a separate pathway to support endurance and fat loss. Because it is not androgenic, adding cardarine at 10 to 20mg daily alongside Ostarine is a stack some beginners use, since it does not add extra androgenic side effects. Still, discuss any stack with a doctor before starting.
