I feel that the instructions provided are somewhat limited when it comes to the preparation of each peptide. I would appreciate having more detailed and specific information, or perhaps personalized instructions for each one, as it can be a little confusing to know exactly how to prepare each vial correctly.

Hi Sonia, thank you for sharing your feedback. As a research chemical supplier, RIVN Research LLC sells all products strictly for in vitro laboratory and scientific research use, as stated at checkout and throughout our website. Due to legal and regulatory restrictions on research-only compounds, we're unable to provide reconstitution instructions, dosing, protocols, or usage guidance of any kind — this applies uniformly to every customer and every product, and isn't something we're able to make exceptions on. We understand this may not be the answer you were hoping for, but we want to be transparent about why: providing that guidance would put us outside the bounds of how these products are legally permitted to be sold and marketed. We're always happy to help with anything related to your order itself — specifications, Certificates of Analysis, shipping, or account questions. Please reach out to [email protected] if we can assist further.
