T-bol is the only oral ever to give me that problem. I'm sure it was actually kidney pains tho. I could hardly even move to do anything. I drank 100% cranberry juice and stopped taking the T-bol and the pain was gone in 2 days.
Tbol also causes my back pumps but as said only at high mgs , var is more pump than the same back pump for me .
Lots of water and taurine helps me .

I get bad back pumps on any steroid, but only on squat day. But the worst are the calf pumps. I walk 2 bocks and my calves burn so bad it feels like they're gonna explode.
