I’ve heard a few different opinions on this from the guys at the gym. You either have
Peptide gains arent technically permanent but won’t wear away like steroids will. You will still get smaller muscles if you don’t eat enough, keep getting older, get sick, stop working out, etc. so there are a lot of reasons why you can get smaller after use but post cycle losses won’t be one of them
No such thing as permanent gains
Which opinion is right?
