Hurts.... bad! Got 20 amps last week, shot 3cc's in my right glute Sunday and 3cc's in my left Wednesday and i'm still in pain today. Have used organon sust in the past as well as tornel supertest, t400 and lots of QV injectables, this by far has caused me the most pain of any, plus i've had the flu all week. On a postivie note, I've been a walking erection all week. Also, each amp does contain 1.5 mL as advertised, and the labeling and box looked professionally done, but i've been in too much pain all week to continuing putting those oils in my body.
