Steven V.
have ordered from them twice. Second order was delivered to the wrong address, not their fault. I messaged them to let them know, in case it was returned. They emailed me back at 8pm, giving me advice on what my next steps should be with the carrier. Package eventually found its way to me. Everything I have ordered has been top quality.

Hi Ryan, thank you for your feedback. We appreciate you choosing Onyx Biolabs for your research needs. Please keep in mind that our products are strictly for laboratory research purposes, and outcomes can vary significantly based on the specific research protocols being followed. We stand behind the quality of our compounds with third-party COAs to verify purity. We look forward to your update as your research progresses.

Hi there, we take the integrity of our research compounds and our reviews very seriously. Upon reviewing our inventory and sales records, we have noted a significant discrepancy: Onyx Biolabs does not sell or manufacture a 20mg vial of Tesamorelin. Because you are describing a product that does not exist in our catalog, we are unable to verify this as a legitimate purchase. We have invited you to provide an Order Number for verification, but as we do not stock the item you described, we will be continuing our dispute with Trustpilot to have this fraudulent content removed.
