What’s going on fellas need some help. On my 4th week of a test p,tren a, tbol cycle. Everything has been going great. Lost 2% bf and packed on some nice lean quality muscle. This week though I have had horrible lower back pumps. Like completely debilitating to the point where I can do any deads at all. Was doing them this morning I usually warm up with 225 and I couldn’t even pull that 5 times without almost falling down. It’s that crippling. Been taking 3 grams taurine and it’s doing nothing. Wondering if anyone has any ideas to help. And before anyone asks I’m drinking plenty of water usually a gallon and a half a day. This is a first for me. I’ve never had lower back pumps before. Have had shin pumps and taurine usually helped so I’m out of ideas. Thanks in advance
