What is Ostarine?

Ostarine is the SARM that is being developed for the prevention and treatment of muscle wasting. It is currently undergoing clinical trials and may eventually be the medical prescription for prevention of cachexia, atrophy, and sarcopenia and for Hormone or Testosterone Replacement Therapy.

As a research chemical, Ostarine belongs to a class of chemicals known as SARMs or selective androgen receptor modulators. SARMs create selective anabolic activity at certain androgen receptors and not others, hence their name. Compared to testosterone and other anabolic steroids and prohormones, the advantage of SARMs such as (Ostarine) MK­2688 is that they do not have androgenic activity in non­-skeletal­-muscle tissues. Ostarine is effective in not only maintaining lean body mass (LBM) but actually increasing it. It is often described or named S1 on various internet sources, however this is actually incorrect as S1 was a SARM that was developed quite early and is no longer undergoing any further development.

Lean muscle gains (bulking)

Doses of 25mg for 6-8 weeks are the most common protocol for such goals.

Losing Bodyfat (cutting)

A 12.5-­15mg dosing protocol for 4­-6 weeks is good for cutting with Ostarine without undergoing anya side effects or suppression.

Injury Prevention

Doses of 12.5mg per day is recommend for such purposes and improvement in joint movement that can be seen after just 6-­8 days.
