I don't know where some of you guys get your info.... but you shouldn't wear a belt. Do some research! and I'm not talking about asking the guys in the gym....
how much time did you have off from your last cycle? what was you PCT?
The pop should be kicking in around now - give it a few more days. The pain from the injection can vary from person to person - and even shot to shot.
Sorry I don't know the labs but sounds like an underground lab - even...
