The peptide industry
had a problem.
We fixed it.
Most peptide suppliers operate in the shadows — no documentation, no independent testing, no accountability. PurelyAminos is the industry's answer: third-party verified, COA-backed, transparently sourced. Every vial. Every time.
Every Batch.
Unbiased. Documented.
what's in the vial.
Most peptide suppliers
operate in the dark.
Researchers deserve to know exactly what's in every vial. The peptide market is flooded with suppliers who can't — or won't — provide basic documentation. That's a research problem. We're the answer.
"The standard we hold ourselves to is the standard the industry should have held all along."
— PurelyAminos Quality CommitmentBuilt differently. Held to a higher standard.
Four pillars that separate PurelyAminos from every other peptide supplier in the market.
HPLC Purity — Every Batch
Reverse-phase HPLC with UV detection. Raw chromatogram data retained on file. Purity reported as % area — the scientific standard, not a marketing number.
Identity Verified by Mass Spec
Every lot confirmed by electrospray ionization mass spectrometry (ESI-MS). Observed molecular weight vs theoretical — documented on every COA.
COA With Every Order
Not on request. Not "available if asked." A full Certificate of Analysis ships with every single order — lot number, test date, purity, identity, storage.
US Lab Tested. Transparent.
All analytical testing performed at US-based laboratories. Full traceability from raw material to final product. No black-box supply chains.
Featured Research Peptides
Every product ships with a full Certificate of Analysis. HPLC-verified purity ≥98%. For in-vitro research use only.
All products for in-vitro laboratory research use only · Not for human or animal use
Every vial ships
with the proof.
A Certificate of Analysis isn't a bonus at PurelyAminos — it's a baseline requirement. Every lot ships with documented purity and identity data. No exceptions. No "available on request."
