ONVYTAL supplies research peptides, GLP-1 support compounds and NAD+ today as a professional-only supplier. This page explains how batches are sourced, tested and handled before they ship, and the licensing work underway to add a physician-reviewed GLP-1 track.
Stock is allocated by lot rather than pooled inventory. When you reserve a size, you're reserving from a specific manufacturing batch — the documentation you receive corresponds to the exact vials shipped.
COAs are available on request and, where provided, include both an HPLC purity figure with a viewable chromatogram and a mass-spectrometry identity match. A headline purity percentage with no supporting chromatogram is not a verified claim — see our blog guide to reading a peptide COA for what to check on your batch's certificate.
GLP-1 items (marked with the ❄ badge) ship in insulated packaging with cooling elements and should be kept refrigerated at 2–8 °C, not frozen, both before and after reconstitution. Peptide vials are generally stable at −20 °C long-term when sealed, and at 2–8 °C once reconstituted, away from repeated freeze-thaw cycles. Storage requirements vary by product — see each product page's Handling tab.
Products are supplied to licensed practitioners, trained professionals and research professionals operating within their applicable regulations. They have not been evaluated by the FDA and are not intended to diagnose, treat, cure or prevent any disease. Nothing on this site constitutes medical advice or a dosing recommendation. Purchasers confirm they are qualified to handle these materials and accept responsibility for lawful storage, use and disposal in their own jurisdiction.
For the GLP-1 weight-loss program, we're onboarding a network of licensed U.S. physicians, a compounding pharmacy partner, and payment processing certified for this category — none of these partnerships are finalized yet, so no prescriptions are issued through this site today. We'll update this page as each piece goes live. See the program page for current status.
