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.

Verified purchaseI have been using your company for nearly two years and have consistently been impressed with the services you've provided. Throughout that time, I have frequently recommended your company to others because of the positive experiences I've had. However, I wanted to share some feedback regarding my last two orders. Your customer service, shipping, and website navigation continue to be top-tier. As a loyal customer, I felt it was important to bring this to your attention. I truly value your company and hope this feedback helps maintain the high standards that initially earned my trust and continued business.
