I just ran a cycle of LGD, RAD140 and GW so since I stacked them I cant count for individual performance however my squat went from a 225 struggle to I just squatted 375 today . That is in 12 weeks so clearly sarms can make a HUGE difference . My cardio and endurance has improved greatly , especially the recovery time between sets - I put that down to the GW amazing stuff ! I did a thread on here about my 12 week cycle . I plan to run MK2866 and S4 with GW as my next cycle for cutting and strength.
