Product is always super pure I’ve ordered from Onyx three times and have never had any problems. All their products have given me fantastic results and I will continue to use them.

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.
Onyxresearch (onyxresearch.shop) has 227 customer reviews on Five Star Index, with an average rating of 4.2 out of 5.
