I have used ostarine I find it fairly effective at increasing energy, building muscle, cutting fat and maintiang strength. It is also very nice for your joints. I would take it 6 to 7 weeks (and run an otc pct). Don't think it's actually as effective as test (even though it may be refered to as a test substitute) but a lot of people run it at low doses during pct to help keep gains. Suming up, Decent bulker probably best used as recomp effective at cutting allows you to maintain strength and mass while burning fat.
