My friend got some premixed omnitrope vials by Sandoz. They were shipped from overseas in the EU, and anyone who uses hgh knows not to shake it up, and I'm sure that vial got shook to hell in transit, so wouldn't this stuff be done for? That is how all of the omnitrope comes, though, is premixed, so maybe they found a way to keep it stable in water even when in transit. Does anybody have any experience with this, or make a comment about the possible harm to the product when being shaken during transit?
