Ostarine is one of the first SARMS to hit the bodybuilding industry and it’s still being used today. This SARM can increase bone density, improve lean body mass, and aid in body recomposition… just like resistance training would. This SARM makes a good edition to almost any stack. Ostarine has one of the lowest risks for side effects, running it for less than three weeks users shouldn’t expect any serious side effects at all. Ran for three or four weeks the recovery should still be rather quick and a lot of users don’t report anything noticeable in terms of side effects for this length of run.
