I found one source that sells a Kit of 100iu's for $450. If it takes 2 days for it to get to me, does it have to be shipped with dried ice? The guy said GenSci doesnt have to refrid. until you use it, is this true? I have read some people say they can get the same Kit of Jintropin for only $250, and a lot say $300. Do you get it from china, mexico or somewhere else? Im nut sure if mexico sells it but I would think that would be the only place selling it for that cheap. Right now Im using Lillys Humatrope and I have to bulk order it to get a decent deal and it still cost $8.50 per IU, so if Jintropin is as good I would save a ton of money!
