Verified purchaseIve ordered from the grey market before directly and the big difference between tested and non tested is the caps and plungers. I trusted this site with there testing and i get sent not 1 but 3 untested vials. Lost faith in this company

Verified purchaseThe shipping was fast. The packaging was a little flimsy, as I thought that it would have a little more protection as it is glass.
