no bro, absolutely not... it is definitely a dream combo.. TRT, sarms and proviron is my go to stack in between cycles.. its like never being off and the beauty, NO steroid side effects whatsoever... its just best to take 3-4 weeks off after 12 weeks of sarms so you do not desensitize but otherwise, that's all you have concern with...
Definitely no PCT needed if you are on TRT. I run sarms off and on through my TRT and they certainly add a lot of benefit even between blasts. They are very versatile, and this is just one of the many ways they can be utilized
