Quality you can verify, not just trust. Every Aeterna peptide moves through a controlled, documented process and is released only when it meets our standard — above 99% purity, confirmed by independent testing.

1. Raw Material Verification

Every input is checked for identity and quality before synthesis begins. Nothing enters production until it has been verified against our specifications.

2. Controlled In-House Synthesis

Compounds are produced under documented internal quality procedures designed for batch-to-batch consistency. Controlling synthesis in-house lets us hold every step to the same standard rather than relying on unverified third parties.

3. HPLC Purification

Each batch undergoes multiple high-performance liquid chromatography (HPLC) purification passes to isolate the target compound and remove impurities, driving purity above our 99% threshold.

4. Independent ISO 17025 Testing

Every batch is sent to an ISO 17025-accredited third-party laboratory for independent identity and purity analysis. We do not rely solely on in-house results — accredited verification is the standard for materials researchers can trust.

5. Certificate of Analysis

A batch is released only when it passes. Each one ships with a Certificate of Analysis documenting its identity and purity, available to download so nothing about our quality is taken on faith.

6. Sealed, Lyophilized Vials

Verified compounds are lyophilized and sealed in sterile vials, packaged to protect their integrity through storage and transit.
