Our Standards
You Shouldn't Have to Take Our Word for It
Every compound we sell is sent to an independent lab before it goes on the shelf. They run HPLC and LC-MS tests to confirm identity and purity. We publish the results as a Certificate of Analysis, one per batch, downloadable on every product page. If a vendor won't show you test results, ask yourself why.
Independent Testing
An outside lab verifies every batch for identity, purity, and composition. We don't test our own homework.
Batch-Specific COAs
Every product page has a downloadable COA tied to the actual batch you're buying. Not a generic document, the real data.
GMP Manufacturing
Our peptides are synthesized in FDA-registered facilities that follow Good Manufacturing Practice standards.
Multi-Point QC
Quality checks at synthesis, testing, packaging, and fulfillment. Four chances to catch a problem before it reaches you.

Three Steps. No Guesswork.
Pick Your Compound
Browse by research area or search the full catalog. Every product page shows the molecular formula, purity data, and published research — plus a downloadable COA. You'll know exactly what you're getting before you click "Add to Cart."
We Pull, Inspect, and Pack
Your order is matched to current inventory and its batch COA. We inspect the vial, verify the lot number, and pack it in temperature-conscious packaging. Nothing ships without passing final QC.
It Shows Up. You Get to Work.
Discreet packaging, fast delivery, and a digital COA you can access anytime. If something's wrong, our support team is real people who answer real questions.

What People Actually Say About Us
The purity documentation alone sets OSYRIS Health apart. Their COAs are clear, batch-specific, and easy to verify.
Dr. Michael Chen
Clinical Researcher
I've worked with half a dozen peptide suppliers. OSYRIS is the first one where the packaging, testing, and communication all feel aligned.
Sarah Jennings, DPT
Physical Therapist
Fast shipping, impeccable packaging, and documentation that makes internal review painless. That combination matters.

About OSYRIS
We Started This Because the Bar Was Too Low
Most peptide vendors look like they were built in a weekend. Generic templates, vague claims, and COAs you have to email customer service to get. We thought the market deserved something better — a brand that treats research compounds with the same seriousness as the people who buy them.
OSYRIS isn't about shortcuts. We vet our suppliers, test every batch independently, and publish the results right on the product page. It takes longer. It costs more. But the people who find us tend to stay — and that's the point.

Things People Ask Us
What are research peptides?
Peptides are short chains of amino acids — smaller than proteins, but built from the same building blocks. Research peptides are synthesized in labs for use in scientific experiments. They're tools for studying biological pathways, not products for human consumption.
Why does OSYRIS publish COAs for every batch?
Because you should be able to verify what you're buying. A Certificate of Analysis from an independent lab confirms the compound's identity and purity. We think every vendor should do this. Most don't.
What testing methods do you use?
Our independent lab uses HPLC (High-Performance Liquid Chromatography) and LC-MS (Liquid Chromatography–Mass Spectrometry). HPLC measures purity. LC-MS confirms molecular identity. Together, they tell you exactly what is in the vial.
How fast do orders ship?
Most orders ship within 1-2 business days. Delivery typically takes 3-5 business days depending on your location. We use discreet packaging with temperature-conscious materials.
Do your peptides come as powder or liquid?
Most ship as lyophilized (freeze-dried) powder in sealed glass vials. This form is more stable and has a longer shelf life than liquid. Some products like NAD+ ship in solution.
Can I see the COA before I buy?
Yes. Every product page has a downloadable COA linked directly to the current batch. You don't need to create an account or email us to see it.
