Chad
This company is awesome! Had one time the wrong peptide was sent to me, which was quickly exchanged, and one occurrence of research peptide getting degraded during transport, (it was during a week of>100 degrees F while it was transported) which was promptly replaced. Other than that the other 10+ orders have been accurate, pure, correct dosage, and quick to be shipped and received. Highly recommend this company due to the cheaper than average prices, and the excellent customer service.

We truly appreciate your continued trust in our research materials and look forward to supplying your next order!

JANE ELIZABETH H.
Onyx Biolabs is by far the most responsive and best managed and packaged of any research labs I have used. Their prices with discounts are competitive with any, but what distinguishes them is the ease of their packaging and supplies along with their unparalleled support. I frequently ask them questions through their email and they reply immediately with thorough explanations and clarifications. I could not be more impressed and they have become my only supplier and resource. They treated me like a VIP from the very beginning. Again, this level of domestic testing and expert responsiveness is unmatched. Do yourself a favor and just try them. You will never ever go anywhere else.
