I absolutely love Onyx Biolabs. Every product has been great and their prices are excellent. I’ve not had a bad experience at all. Pricing is reasonable, everything arrives within days and I’ve never had any issues with any product I’ve ordered from them. 5 stars across the board!
By Teri C.
Have ordered from onyx several times, they have amazing quality great customer service and I recommend to everyone. I accidentally left my unit number off my address and contacted them to catch it before it was packed and they got back to me right away and fixed it. I also love that every batch has QR codes to lab results for 3rd party testing

Onyx is absolutely THE #1 company in the pep business!! They have GREAT pricing, FULL disclosure on all products, FAST shipping, EVERY possible thing that you could want to order and FANTASTIC customer service!! I can text them day or night with questions or concerns about products, shipping, inventory, testing, or anything else ( and I do and I have multiple times) and they ALWAYS get back to me quickly with answers and info and even have joked around and also had discussions at length and they have NEVER ONCE failed to respond, reply, resolve the issue, leave me hanging, or have me unhappy with what I was told. I have been ordering from them for about 2 months and ALL my blood work has shown improvements in every aspect while my BMI has gone down and muscle mass has remained the same or increased. I couldn't ask for a better company to deal with and I wont deal with anyone else. I have friends and seen and read horror stories from so many suppliers and I know I will NEVER have any of those issues. If youre even thinking about giving peps a shot, ONYX is THE ONLY place I recommend and fully support!! Thanks ONYX!! KEEP DOING WHAT YOU DO!!!
