Hard to say. There is some evidence that it is minimally suppressive and some that says it isn't at all
Exactly it suppressed the shit out of me but others it doesnt.
2 weeks I dont know if you would see much but for most people its not going to suppress you much.
Again just giving my feedback as I never had such suppress on just sarms and have always run from the same sources and when I added proviron my test was stupidly low.
Bloods were run at the end of my cardarine, sten, osta, LGD, RAD140 and proviron cycle. Doses of Osta were 25mg/day, lgd 10mg/day, rad140 20mg/day, proviron 50mg/day. I have run the same stack before and have not been suppressed anywhere near as much so the proviron really shut me down. Now it could have just been exacerbated by the sarms but I am not sure if I would run it again with sarms.
