I think the pain associated with t400 is HIGHLY overrated....I'm doing 1cc of tren and 1/2.cc of t400 6 days a week and have no pain at all.....Sex drive is through the roof and gains are coming along good and Hell i'm just in week 3....WARNING...DO NOT shoot 1cc of t400 in your ass at one time, as that will hurt......Pretty simple to figure out if you ask me...
