I'm on week 3, I frontloaded also, along with deca and EQ. I am also on clen, t-3 and arimidex, have not gained a single pound, or any strength yet.
I was under the impression that frontloading would have made this kikc in already, so I probably wont frontload anymore, but if the gear kicks in this or next week, I'll be happy.
As for the pain, I mix 1cc of t400 with 1-1.5cc of deca and EQ. No more pain than sustanon.
hope that helps
