The stuff is the bomb, but to get your moneys worth, you need to do it for at least 16 weeks, 4-6IUs per day, and you have to stack it with Testosterone, Insulin, t-3, and mabey even IGF-1 LR3. So, be prepared to spend a couple of grand, unless you have a sweet connection, then mabey around $1,200. I like Jinotopin...great product. All I can say is that you need to do some extensive research on insulin use before you use HGH. Only use Humalog slin, and make damn sure you take in 100 grams of simple carbs immediately after you do your insulin shot. If you don't, you can and will die. Growth Hormone splits your muscle cells, test. blows them up, insulin drives carbs and protien into the new cells. You will feel great on this stuff...like a 15 year old athlete in an adults body and muscle.
