Onyx BioLabs looks like a real, operating US seller. It lists a company name, a Charlotte, North Carolina address, a support email, a phone number and written shipping and refund terms. Nothing in the material behind this page documents it as a scam. It sells peptides only “for research use only”, so the useful answer is about what that label means for your order and how to protect it.
Affiliate disclosure: Plainly, the product link on this page is an affiliate link. If you buy through it, this site may earn a commission.
Who sells Onyx BioLabs peptides, and how do you reach them?
The seller's refund and privacy policies say the store is operated by Onyx Holding, LLC. The contact page lists a Charlotte, North Carolina address. The seller describes itself as a chemical supplier and says it is not a compounding pharmacy as defined under sections 503A or 503B of the Federal Food, Drug, and Cosmetic Act.
| Contact detail | What the seller lists |
|---|---|
| support@onyxbiolabs.com | |
| Phone | +1 (704) 665-5551 (the contact page marks it text only) |
| Support hours | Monday to Friday, 9:00 AM to 5:00 PM EST |
| Order tracking | Track Order page, using your Order ID and billing email |
| Claims response | The refund policy says it aims to answer claims within 1 to 2 business days |
Keep every order email. If a confirmation does not arrive, the seller says to check your spam or junk folder first.
What does “for research use only” mean for you?
The seller's pages say all products are for laboratory, in-vitro or analytical use. They say human and animal consumption is prohibited and that the statements on the site have not been evaluated by the FDA. The terms also say the products are not FDA authorized to diagnose, treat, cure or prevent any disease, and that they are not supplements.
Research-use-only products are not FDA-approved for human use. A compound can have an approved prescription form made by a drug company, and a research-grade vial from a chemical supplier is still not that approved product. To check a specific compound, search the FDA's drug databases or ask a pharmacist. Cleveland Clinic cardiologist Eileen Hsich describes the FDA as the agency that approves drugs and devices. That approval is what a research-use-only label does not carry.
The site asks you to tick two boxes before you enter. One says you are at least 21. The other says you are a qualified researcher and understand the products are for in-vitro use only. The seller also says its catalog is visible only to verified researchers, with free account verification.
Which compounds does Onyx BioLabs sell?
The seller keeps its catalog, pricing and full compound list behind a sign-in, so the compounds are not public on the page. The vial images and banners on the site show these names:
| Name as shown | Label detail | What to know |
|---|---|---|
| BPC-157 | 10MG | A 2025 review in the journal Arthroscopy calls it an experimental peptide. It says peptides like this are unregulated yet readily available online, with scarce clinical literature on tendon, muscle and cartilage injury. |
| GLOW | label reads 7OMG | Research-use-only vial; not FDA-approved for human use |
| KLOW | 30MG | Research-use-only vial; not FDA-approved for human use |
| Glutathion (as spelled) | label reads 150 | Research-use-only vial; not FDA-approved for human use |
| Tesamorelin | 10MG | Research-use-only vial; not FDA-approved for human use |
| SPC-157+TB | 5MG | Research-use-only vial; not FDA-approved for human use |
| HCG | named in a clearance banner | The seller says it is being discontinued |
For each of these, the vial you would receive from a chemical supplier is not an FDA-approved product. If you want background on one of them, our BPC-157 research overview covers it. For how to weigh early findings, see this guide to preliminary research findings.
Can you verify its purity and lab reports?
The seller says every batch is tested by a third-party lab, Kovera Labs, using HPLC and mass spectrometry. It says results show at least 99% purity and that the reports also test net content to avoid under-dosing. It points to a Lab Results page and certificates of analysis (COAs). The seller also says its entry in the site footer is “Verified by Metrix”.
These are the seller's statements. You can check them in a practical way:
- Ask support for the COA that matches the batch or lot number printed on your vial.
- Check that the COA names the lab, the compound, the date and the purity method.
- Ask whether the lab is independent of the seller, and how you can confirm a report with the lab directly.
The homepage also shows a 4.6 out of 5 rating, a “trusted by 30,000+ researchers” line and a set of buyer comments. The seller chose those. Treat them as the seller's marketing.
Where do the seller's own pages disagree?
- The homepage says “we guarantee” every vial meets strict analytical standards. The terms say Onyx BioLabs makes no warranty, representation or guarantee about the products.
- The homepage promotes a “qualified peptide catalog”. The About page describes analytical reagents, laboratory solvents and assay reference standards, without using the word peptides.
- The homepage talks about verified researchers and strict compliance. Entry on the age and research gate is by checkbox, and account verification is described as instant and free.
Neither point proves anything wrong. They tell you the written terms, not the sales copy, are what govern your order.
What does it cost, and what offers does the seller run?
Product prices are not public because the catalog is behind sign-in. As of October 7, 2026, the seller's banners list these offers; check the checkout for what applies today. You can look at the current catalog and checkout on the seller's Product Page.
| Offer | What the seller says |
|---|---|
| Prime Day flash sale | Buy 1 get 1 free with code PRIME, ending 10/7 at 11:59 PM EST; excludes OBL-1 SM, OBL-2 TRZ, OBL-3 RT and reconstitution solutions (10mL and 3mL) |
| First order | 25% off for joining the email list |
| HCG clearance | Extra 25% off while supplies last |
| Payment stack | Extra 5% off when paying by Zelle, Cash App or Link Money |
| Grant program | 20% off for academic faculty, clinical staff, defense and first responder research personnel, verified through VerifyPass |
The seller says it accepts credit and debit cards, ACH and bank transfer, Zelle and Cash App, and cryptocurrency. A discount for one payment method is the seller's choice. It is worth asking your own bank what protections apply to the method you pick.
What are the shipping and refund terms?
| Topic | What the policy says |
|---|---|
| Processing | 24 to 48 hours after payment confirmation; no weekend or holiday shipping; the seller notes delays during high volume |
| Standard shipping | $11.99, 3 to 5 business days; free on orders of $200 or more |
| Expedited shipping | $19.99, 1 to 2 business days |
| Shipping protection | Route insurance covers theft, carrier loss and breakage; if you untick it, the seller says it is not responsible for lost, stolen or damaged packages |
| Returns | All sales are final; no returns or exchanges |
| Damaged, wrong or missing items | Contact support within 48 hours of delivery with photos of the product, packaging, shipping box and packing slip, plus your order number |
| Lost packages | Counted as lost after 7 or more days with no tracking movement; replacement or refund only if the order was insured |
| Marked delivered | No refund or replacement without shipping insurance; with it, contact the seller within 48 hours |
| Refund timing | Card 5 to 10 business days; ACH 5 to 7; Zelle or Cash App 1 to 3; crypto refunded in the same coin at the USD value at the time of refund |
| Shipping fees | Not refundable unless the seller is fully at fault |
| Not covered | Change of mind, ordering the wrong product, misuse, contamination, improper storage, wrong address |
In practice, the 48-hour window is the rule that matters. Photograph the box before you open it and keep the packing slip. The shipping protection add-on is the only cover for lost or “delivered” packages. The terms also include a hold-harmless clause and say North Carolina law governs disputes.
Is it illegal to buy research peptides or to be caught with them?
This page can't tell you what is legal where you live, or what happens if you are found with a particular compound. The answer depends on the compound, your location and how it is used. The Arthroscopy review notes that clinicians should keep up with the safety, ethical and legal profiles and regulations for synthetic peptides. For a firm answer, ask a lawyer or your state's authorities.
The seller's position is plain: it sells only to people who confirm they are 21 or older and working in a laboratory, and it prohibits human or animal use. A purchase that does not fit those terms is outside what the seller says it sells for.
Which peptides are legal, do they fail drug tests, and what do public figures take?
This page covers the seller, not personal use, so it does not list legal compounds or name what any public figure uses. Drug-test results depend on the specific test and compound. Ask the organization running the test, or a pharmacist or clinician, before you rely on any assumption.
Is Onyx BioLabs the same as other “biolabs” companies?
No. Many unrelated companies use “bio” and “labs” in their names, including firms that make lab reagents, not research peptides. Before you order, match three things to this seller: the web address onyxbiolabs.com, the company name Onyx Holding, LLC, and the Charlotte, North Carolina listing.
What is the most legit peptide company?
No single seller can be named as the most legit. A fair comparison uses the same checks for every seller: a named company, a real address and working contact, batch-level lab reports you can match to your vial, clear refund terms and consistent wording across the site. To see how complaints about other research-peptide sellers tend to look, read our pages on Synthesis Peptides refunds and shipping and Loti Labs billing and refunds. For marketing claims in general, see this guide to ingredient evidence versus marketing.
Before you order
- Ask support for the COA for the lot number on your vial, and who ran the test.
- Ask for the full compound list and prices in writing, since the catalog is behind sign-in.
- Decide on the Route shipping protection before checkout; the refund terms depend on it.
- Photograph the package on arrival and report problems within 48 hours.
- Check which payment method gives you a way to dispute a charge, and ask your bank if unsure.
- Look up your compound in the FDA's drug databases; a research-use-only vial is not FDA-approved for human use.
