Why VialPepLab Exists
The research peptide market is full of suppliers who cut corners — vague labeling, no batch traceability, "research only" disclaimers slapped on opaque products. We started VialPepLab to change that.
Every vial we ship carries a batch-specific Certificate of Analysis. Every COA is generated by independent third-party labs using HPLC and LC-MS. Every batch tested below 99% never leaves the warehouse.
What We Stand For
Verified, Not Claimed
Every batch ships with an independently-generated COA. HPLC chromatogram, LC-MS spectrum, batch number, synthesis date — viewable before you order in our COA Library.
≥99% Or It Doesn't Ship
Our purity floor is 99% by reverse-phase HPLC. Below that, the batch is rejected — not blended down, not relabeled, not held in inventory. Rejected.
Lab Use Only — Stated Plainly
We sell to qualified researchers for laboratory work. We do not market for human or veterinary applications. Our copy reflects that — no dosing guides, no protocols, no claims.
How We Source & Test
Synthesis
Solid-phase peptide synthesis (SPPS) via Fmoc chemistry. Manufacturing partners audited annually for GMP compliance.
Purification
Reverse-phase HPLC purification. Fractions collected, validated, and pooled to reach minimum 99% purity.
Independent Verification
Third-party lab re-tests batch by HPLC and LC-MS. Batches that fail independent verification are destroyed.
Cold-Chain Distribution
Lyophilized and sealed in glass vials. Held at -20 °C in US and Canada warehouses until shipping.
Who Uses VialPepLab
Our customers include academic research labs at universities across the US and Canada, independent investigators in regenerative medicine and longevity research, contract research organizations needing reliable reference compounds, and dermatology and cosmetics R&D teams.
What We're Not
We are not a pharmacy. We are not a compounding lab. We do not sell drugs. We do not advise on human or animal use. If you're looking for that, this isn't the right vendor.
