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

The 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 found that AIO peptides had alot to offer, their support was great as well as their quick delivery. I did have an issue when trying to pay via a credit card. They ended up running it as cash which created a large headache for me. The system did warn me, however I never had this happen before and I overlooked it.

While I didn't particularly care for the Pink color, it's a great way to store and protect my research compound vials from harm. I had some transparent ones but the transparency defeats the purpose of keeping the research compound in safe, cool and dark (away from light) storage. I'd love to see more color selection!

Verified purchaseI have been very happy with most of the research compounds I have received from AIO. Other than those things I have been happy with the research compounds and prices from AIO.
