About 6 months ago I got some Sustenon 450, from a chemist friend, I am no newbie to high mg gear but this shit was the worst I ever touched. 1cc made me almost completely crippled, (felt like I had been kicked by 10 horses in the same spot) it lasted for about 10 days, on top of that I was sick as a dog, no training, eating, or anything. I was bed ridden for about 4 days hot sweats cold sweats, nausia, and incredible back and joint pain. I thought it was me so I gave a friend a cc of it and the same exact thing, then I gave it to another friend (LOL) and again the same thing. I tried diluting it with 1cc of 50mg/ml EQ and it wasn't that much different. Basically I chalked it up as a loss. and actually gave it to a porn star friend of mine who desn't even train just uses test I guess to stay horney, but he loves it and says it packs a mean punch...more power to him I never want to see that shit again!
There's a horror story for you, did I mention the site was swollen to the point where I couldn't even bend my legs hot and red as a firetruck, I almost went to the hospital cuz I though I developed and abcess.
