Im not quite sure where you are getting your information from but MK-2866 (Ostarine) is pretty much the most widely used and popular sarm amongst them all... It is the most versatile and provides SEVERAL benefits... The way that it enhances a pct and allows one to continuously build strength through this tough period, alone makes it desirable, not to mention the lean muscle gains, the healing benefits, the minimal sides, etc... LGD is going to add more size and does also have some healing properties as well... They are both excellent and you can't go wrong either way...
