It seems to me that it will probably hurt the first time you shoot it but after a while your body seems to get used to it and it does not hurt as much but i am talkin about the old Denkall T400 the new shit i tried did not hurt at all but did not seem to work very well either also just FYI the stuff is way underdosed it is actually only 330mg/mL I hope that is what you where talkin about
I haven't used the PL T400, but that Denkall stuff put me down for a few days. PL is good stuff, so you could always use their T400 and cut it with some of their deca or eq and see how that works or just use 2ml's of the Test 200.
