First sarm cycle for a former football player. I played division II for 2 years as a starter and did good enough to get a chance to be scouted into the NFL but did not make it. got an invite to CFL but decided to go different route. I'm right now 195 pounds at 6 foot tall. I cannot decide between RAD140 and MK ostarine, which one is better if i want to gain some decent size?
