ok i got some test e and when i took a good look there where two different types of marking on the amps. this is the Iranian test so most of them have the white dots, however there are some that have a black dot. i did some research here on the forum and found out that the newer amps come with black dot. so i figure that was that, but yesterday i was looking at the amps, and the one with the white dot (supposedly they are batch # 77 and 78) they don't have a manufactured date or an exp. date like the black dots do. here is the kicker my first shot that i took was a black dot no pain no soreness the very next two shots were white dot and they were alitte painful and the soreness has stay for about three days. if you have any help with weather the white one are real or not??
