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.

The 48 hour turn around has been great since my last order but overall the best company I’ve ordered from - want the affiliate program to launch so all these people I refer I can get a lil something from

Absolutely have seen fantastic results
By hayden S.
Updated and corrected review!! I placed my first order, skeptical of which company to make my first purchase with. Onyx did not disappoint. Fast shipping, product itself was effective and pure, everything went smooth so I placed my second order. I did run into a small issue with one compound, and at first my follow-up emails went unanswered, which was frustrating in the moment. But it turned out to be a misunderstanding with how my messages were being routed, not anyone ignoring me. Once it got sorted, Kenzie was genuinely attentive, understanding, and stayed on it until everything was fully resolved. Peptide journeys can be stressful in finding the right company to trust. Onyx stood behind their product and are there for their customers when needed. What matters to me is how a company handles things when something goes wrong, and for that reason, I will continue to do business with Onyx. High recommend. This is a genuine review from a real customer.

Response from Onyxresearch· Jul 24, 2026
Thank you for taking the time to write this, and I'm sorry it's the reason you did. Going unanswered after four follow-ups isn't the standard we hold ourselves to, and there's no version of that I'm going to defend. You reached out with a straightforward issue and we left you without a response — that's on us, and I apologize. I'd like the chance to actually resolve what you originally wrote in about. Please email me directly at [email protected] with "Trustpilot — Kenzie" in the subject line and I'll pick it up personally rather than routing it back through the general queue. If you still have your original ticket or order number, include it and I'll pull the history so you don't have to explain it a third time. We're also reviewing how your messages fell through so the next customer doesn't have the same experience. I appreciate you flagging it, even though I wish you hadn't had a reason to.

A responsive customer service team and had good results for my first order. Unfortunately only complaint is that it advertises as shipped same/next day but took longer. Also sadly missed out on a promotion due to an error on the website and got in touch w service. During this issue the promotion ended and they were not able to honour anything so had to pay full price. Looking forward to next promotion.
