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 ordering from AIO for several months now and have never had a bad experience! From a process point, they are extremely affordable compared to some others. Their customer service is also exceptional. The only time shipping was delayed was over the 4th of July weekend. And that was expected since it was a holiday! I always appreciate their quick responses to my questions and inquiries. I order a wide variety of research compounds from them from RC-01, BPC-157, TB-500, MT1, PT-141, AOD-9604, NAD, and more. I do wish they would get the SS-31 back in stock, but other than that, they provide me with lots of variety!! They always package the shipments very well, and fedex has never lost one of my orders! I am appreciative that I support a veteran owned company in my home state of Texas as well, and we'll continue to do so!
