I'm 28 and consider myself an experienced user. I've ran quite a few different kinds of test P in the past so I know what I SHOULD be feeling. The injects are not painful at all and I would think that with 200mg/ml they should be a lot more severe than the stuff that is dosed lower. I dunno last cycle I ran was GP had good results with that at 600 mg a week so..I'm thinking maybe bad batch or something becuase everything else is good to go had three days in for weeks that I was off track because my bitch ex gf left me for some nerd and kicked me out of her house. So I guess im going to try upping the dose for a week and see if anything changes.
