Good experience with Modified Aminos. Got exactly what I needed with a quick shipping turn around time. Easy to navigate website and checkout. There are even built in promo deals to save you some money. Will shop again.

Great experience with Modified Aminos. What sold me was the support — I emailed before buying and they took the time to walk me through exactly what I needed. I use these for pre-clinical research studies — The documentation and COAs are exactly what I need as a researcher — everything checks out.

I did lots of research to find a fair price with COA for 5-Amino-1MQ making sure that there wouldn't be any cross contamination issues.
