I ran S4 and Ostarine stacked (both from sarmssearch) for 8 weeks. The goal was recomp mostly. I started out at 170 around 9% bodyfat and ended at around 166-167 at 5.7% bodyfat (3 point caliper tested). The end of that 8 week run is what is now my avi pic. I could go on and on about how great it was, but a picture is worth a thousand words!!
