It's probably not too different from test E right now but certainly better than test C, although I was never able to dose cypionate above like 80-something mg weekly due to intolerable side effects with that ester.
Sleep is good with prop and estrogen sides have strangely disappeared. I'm actually running labs soon because I want to try to understand what happened there, if I am aromatizing less or just adapted to high E or what. Some of the high E sides I'm used to, including oily skin and feeling more emotional, are gone. I did lose a bit of fat but probably not enough to make a big difference.
The exact opposite thing happens to some men on prop, like JeraJera, who has more aromatization and more E2 sides on short vs long esters. Unfortunately, all of this individual variation severely limits the value of anecdotes like mine - there's not much useful you can learn from my experience that will apply to anyone else.
Anyone with enough interest to read this thread should simply try prop themselves instead of reading about it. Actually, I think anyone who can stand daily injections should try it. There's a significant chance it will be better than the long esters, but there's only one way to find out if that will be true for you.
