QUESTION??? When you go to the WEB SITE of the firm that is printed on your vials to check if it's authentic and it pops up "Product authenticity:NOT AUTHENTIC" what do you do? Especially since it's from a supposed,credible source. Case in point I have some vials of TEST-PROP (6) that have popped up "NOT AUTHENTIC". Here's the confusing part I have (4) Vials from the same firm and same source delivered at the same time and they popped up AUTHENTIC and on top of that the source is verified by the firm as a legit supplier. Any serious suggestions.
