Yes, I've some vials of Jintropin. I'm currently using 2 i.u.'s a day, and I think I've enough for 3 or 4 months. I've only been using it for some days. They're leftovers from my drug experiments in 2010, and they're about to expire. I'm curious to see what it can do, and don't want them to go to waste. It's very expensive. I'll see if I tolerate the side effects. I always feel sick for some days when I start using, and a bit stiffness in hands and feet are common. My knees are stiff already. It should subside after a while.
