What people say about S-23 and performance
“It personally was my favorite cycle. The strength and size gains were better than RAD.”
“S-23 is very strong but the side effects suck ass for a ton of people, some can use it fine but for others (like me) it has like tren level sides and simply isn't worth it.”
“Really strong, be sure to have test base. Really acnee prone sarm. It felt like tren for me.”
“I get amazing results from rad140 and almost none from s23 which is supposed to be one of the strongest.”
