Onyx Research is a supplier of research-grade compounds.Our model is verification before sale. Every lot is independently tested for purity and identity, and we publish the certificate of analysis for that specific lot before it is listed for sale — so customers can check what they are buying against third-party results rather than a marketing claim. Average lot purity across our catalog is 99.4%. In-stock orders placed before the daily cutoff ship the same business day via FedEx 2-Day with tracking, in plain, unbranded, tamper-evident packaging. Wholesale accounts are available.Products are sold to customers 21+ for laboratory research only, and are not for human or animal consumption. Onyx Research is not a pharmacy or compounding facility.
