Im guessing it was a saline drip? hgh is good in Saline for about 3 days, after that i wouldn't risk injecting it.
next time order some bacteriostatic water.
Anyway, if it was saline then it wouldn't have damaged te growth, Sort of thing you should have looked into before you bought it really mate.
How long was your course? What brand of growth was it and how did you store it?
