Yes, yes I could. I ran six weeks of mega-TRN with ZOL thrown in for the last 3 weeks.
It's been 5 days now, and the back pumps have gotten better, there not crippling anymore, but defintely still there.
I know back pumps aren't very common with TRN, I have done a TRN solo cycle and never got any either, but this time I did, must have been the ZOL thrown in there.
