Mmmmm nottttt really... Although when I've run ace solo I've always done ED pin, this time stacked with the enanthate I'm goin EOD... it's possible the fluctuations are less noticeable?? Total bro science but so far so good I think.
Probably ED pins though is worth it if you don't mind doing it, I used to love injecting (sick I know) so Ed pins were awesome... Now I just find it annoying so less is more atm
