I used CEM Torem last year and tested at 700ish a few weeks after PCT. After another cycle I did Torem + Nolva and tested at over 1000ng/dl. Maybe the batch the OP got was bad or it was a bad bottle (I'm sure not every bottle gets teh same concentration. Maybe the mixer stop and the liquid settled and then started pouring again. I'm sure it can happen).
Also, if you you say you ran PCT and didn't lose any gains then you are basically a lying cunt or your gear was bunk. And you have no clue that gear causes water and glycogen retention that is released when gear is no longer administered.
BRB, running cycle, gaining 30lbs and keeping it all a few weeks PCT.
