Thats odd, I have batch 007, and I'm on my fourth shot as of yesterday(500mg/wk) and yes there is some slight sorness after the injection, but nothing too bad. Just like the sorness you get after shooting sust, my strength is up, and I'm getting that customary bloating in my lower back, so its good. Bro just try it and see for yourself. In my opinion, its pretty good stuff. I always run the barrel of the pin under hot water for about 30-45 seconds before the injection, then you can take a hot rag and hold it over the injection site, that seems to help most people with the pain, again to me its not bad at all.
Just out of curiosity, how do you know that the infection that you got in your testicle was due to the gear?
