Overview
MaxPro Peptides ranks last in our 2025 evaluation based on significant and widespread community concerns spanning every aspect of the vendor relationship. There are no credible third-party CoAs available for any product in their catalog. Multiple researchers have reported that compounds received from MaxPro performed as if inactive in their research assays.
Customer service does not respond to substantive complaints in any meaningful timeframe. We issue a strong caution against ordering from MaxPro Peptides for any research purpose. The risk to research integrity, compound safety, and time investment is simply too high given the available alternatives.

Cannot in good conscience give this more than one star. We received three compounds. All three were inactive in our assays. When I contacted support, I received no response after multiple attempts over three weeks. This vendor is either knowingly or negligently selling products that are not what they claim.

Ordered twice, giving them the benefit of the doubt after the first poor experience. Second order was worse. No CoA provided, no response to support requests, and the peptide we received appeared to be either severely degraded or mislabeled.

I was warned by colleagues and ignored the warnings. Don't make my mistake. Zero technical documentation, a support address that appears to be unmonitored, and results in our models that are inconsistent with any real peptide activity.

MaxPro Peptides is the worst vendor I have encountered in several years of evaluating this market. There is no aspect of their operation that meets even minimal standards. Do not order from them under any circumstances.
