I like e and c because of less frequent pinning, but the rapid return from prop with ed or eod pins is fun too.
Well, I just did my first pin yesterday... I'm on Cyp. I've heard from a lot of people (forum and real life) that C doesn't give as much PIP as E. Heard Test P is the best...but hurts like a bitch when injecting by itself. Any truth?
I've never heard about or experienced a difference in PIP between Test C and Test E, and any difference that someone has experienced is likely due to something other than the ester itself.
Test P is a shorter-acting ester, and can have more PIP because of this. However, Test P that is brewed properly from quality raw materials should not have PIP that is very noticeable, and should be relatively smooth.
