I just ran into an issue with a burning pain when I injected! Taken HGH before and never felt this before! It is a 30 iu premixed Somatropin bottle. The guy said it has a specific acid in it that preserves the mixed solution! I have heard of IGF with Acetic Acid that causes that burn, but never heard of an acid in HGH that burns! Please advise!

I just bought one bottle and waiting to hear from people about this before I pick up more!
