Since a lot of people think most GH is the same and american pharms are ripoffs so it has to be them! Jintropin is 191 amino acids, which I think is the most important thing. I have heard a lot of people say it sucks and so does all European growth. Even if you had to take 2ius of Jintropin to = 1iu of saizen you still save a ton of money. Is there any truth to Lillys Humatrope being better at leaning you out, most people hear the name and think its the best. Right now Im taking lilly and when I run out in 3weeks, Im going to jump on the Jintropin. Lilly is the only one I have ever taken(6ius spilt in 2 injections), has any one on here taken any american and foriegn to compare them, if so list what you took.
