I have nothing but positive feedback. Everything I ordered was a fair price. The lot numbers matched the COA. I emailed them when I had a question and received a response within minutes. My free two-day delivery has always been on time! I will continue to use them.

I ordered NAD+ 1000mg and Glutathione 1500mg from GoAlphaLabs because their website states that every product is tested and that the LOT number will match the Certificate of Analysis (COA) posted on their website. When I received my order, the LOT numbers on both products had no matching COAs available online. I called customer service and was assured that the products had been tested and that the COAs would be emailed to me Thursday night. Nothing was sent. I then contacted customer support by email, and Darlene assured me the COAs would be uploaded on Friday. Friday came and went with nothing posted. Since then, I have received the same promises multiple times, but as of July 14, 2026, I still have not received the promised COAs for the LOT numbers I purchased. Based on my experience, I cannot verify that these specific products were tested as advertised. If providing COAs tied to the LOT number is important to you, I recommend confirming they are available before purchasing.
