Positive experiences
“It personally was my favorite cycle. The strength and size gains were better than RAD.”
“Day 1 s23- Could feel effects after one preworkout dose. This stuff is strong so I think I’m going to back down the dose more to be safe.”
“S23 is nuts... I got Leaner while gaining weight. definently some nutrient partitioning improved and fat metabolism”
“S-23 is by far my favorite sarm. If I had to choose between it and winny or anavar it takes the cake. It's as close to those 2 real AAS as it gets but even a little better in my opinion...I was 184 on the left and 198 on the right.”
“I’ve got good results stacking lgd and s23”
“180mg test 25mg s23 split am/pm. I got lean quick. Dry and vascular. It was like tren lite.”
Negative and mixed experiences
“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.”
“I'm almost convinced that they're underdosed or just garbage...I just started TRT 4months ago on 150mg/week and my body composition has changed from that alone”
“S23 gave me the worst sides out of all of them I got permanent acne on my back shoulders chest arms and stomach.”
“S23 is no joke...This compound is toxic and every time I peed I could smell the toxicity. Even with a low dose.”
