Would like to help you, but Im confused by your wording. Test enanthate is made in the US(and elsewhere) for humans by at least two different companies(name brand and generics) I believe 5ml is the largest vial size of US made enanthate(unless I guess a compounding pharmacy makes it?).
It is not illegal if you have a medical need for it, and it is not illegal to posses if you have a script for it.
post more info, elaborate on your question and maybe someone can help you. Are you just trying to figure out if its fake?
