I am using it Tren Ace currently and pin EOD. I am in my 4th week and I am beginning to see some results. I have not tried pinning ED but was wondering the same thing as you actually. Would pinning ED keep levels more stable and therefore maintain a more anabolic environment for growth? The half life and absorption rate of the Ace ester is long enough for EOD injections, which is nice bc less pinning means less potential for PIP, tren cough, etc. To answer this question best we would need to run a clinical trial otherwise its just anecdotal evidence and when the internet is your source for that you can pretty much hang up any notion of finding the truth.
