I ordered a supplement called 50B. Must be delivered refrigerated. Four days later it arrived in my mailbox where it stayed for another day. I didn’t get a delivery note! Maybe that’s the reason for the problem I got. After I took the first three pills my stomach showed an allergic reaction. I stopped taking them and recovered quickly. I asked the customer service for a refund of the 84$, but this was denied. The don’t accept opened containers. How shall you find out if the supplement works without opening the container??? An on top: they don’t take refrigerated containers back. Other companies are doing much better! My recommendation: DO NOT BUY at Supplement First! Terrible customer service!

Zero customer service . USPS lost my package . They will not respond to voicemails or emails . I got completely ripped off . Do yourself a favor and shop somewhere else !

Product was Counterfeit; I've purchased the product over the counter several time, and the taste was completely different than the product I received from Supplement First. When I complained to them and asked for a refund, they ignored my email.

The FDA banned OTC N-acetylcyctine. SupplementFirst still sold it; I figured they were selling down their existing stock. The capsules lacked the pungent smell and taste of N-acetylcystine. The powder tasted acidic--remarkably like vitamin C. I sent in a return for 4 unopened bottles. They credited me with 3.
