Our manifesto
The research peptide industry
The research peptide industry
has a transparency problem.
We built Pepteez because researchers deserve a supply chain they can actually verify — not marketing copy and unverified purity claims.
Most suppliers
Trust us, it's 99% pure.
- No third-party testing
- No batch-level documentation
- Unknown synthesis origin
- No cold-chain handling
Pepteez
The new standard
Here's the COA. Verify it yourself.
- Independent HPLC + LC-MS testing, every batch
- Public certificate of analysis per vial
- Full US domestic supply chain
- Insulated, temperature-controlled shipping
Why Pepteez
Built for the lab,
Built for the lab,
not the shelf.
Six things every researcher should expect from their peptide supplier — and why we deliver on all of them.
Independent third-party testing
01HPLC for purity, LC-MS for identity — every batch, every time, published on the product page.
Batch-level certificates of analysis
02Every vial carries a unique batch ID linking to its public COA. Full traceability from label to lab.
99%+ minimum purity standard
03Lyophilized under controlled conditions. Proper cold-chain handling from synthesis to your bench.
Next-day shipping, fully tracked
04Orders before 2pm CT ship same day from our US facility. Insulated packaging and tracking included.
100% domestic supply chain
05Synthesized, tested, stored, and shipped entirely within the United States. No international transshipment.
38+ compounds in catalog
