Aethel Peptides supplies laboratories, universities and independent researchers with high-purity peptides backed by transparent, batch-level testing.
Aethel was founded on a simple observation: in the research-peptide market, quality claims are easy to make and hard to verify. Too many suppliers publish a purity number with nothing behind it.
We built Aethel the other way around. Every batch we sell is sent to an independent laboratory before release, every vial carries its lot number, and every lab report is public. If you cannot verify it, we do not sell it.
Original third-party lab reports for every batch, never edited, always linked to the lot on your vial.
Vetted synthesis partners, controlled lyophilization and full batch records support reproducible results from order to order.
We serve the research community only. We do not provide usage guidance, and we do not sell to anyone who intends human or animal use.
Every vial follows the same documented path from synthesis to your bench.
Peptides are synthesized by qualified partners using solid-phase peptide synthesis and supplied with manufacturing documentation.
Each incoming batch receives an Aethel lot number and is quarantined until testing is complete.
A sealed sample goes to an independent analytical laboratory for HPLC purity and mass-spectrometry identity analysis.
Only lots that meet our specification are labelled, published with their COA and released for sale.
Orders ship in insulated packaging with cold packs.
Our team answers every message within one business day.
