Eterna Labs engineers research-grade peptides with uncompromising rigor — every sequence synthesized, verified, and documented with the precision the science demands. Every vial we ship is the proof.
The frustration that started it
Eterna Labs was founded by a synthesis chemist who, while running a comparison study, ordered the same research peptide from four vendors and received four different molecules — one impure, one with unidentified peaks, one that arrived warm, and one that was correct but priced three times higher.
The conclusion was uncomfortable: research-grade peptides are too often sold without traceability — no batch records, no published chromatograms, no cold chain. Eterna Labs began as a single-bench operation with a simple premise: synthesize research peptides with full provenance, documented and defensible at every step.
The eterna mark is a commitment
Every vial that leaves our lab carries the eterna wave. It stands for a written commitment:
- HPLC purity ≥ 99% — verified and signed off by analysts.
- Mass-spec confirmation — molecular weight within tolerance of theoretical.
- Endotoxin tested — LAL-tested, results archived.
- Cold-chain shipping — insulated from synthesizer to door.
- Lot traceability — every vial has a unique ID, and every ID has a Certificate of Analysis.
- Multi-year archive — need a CoA from an old lot? We keep them.
If a single one of these checks fails, the lot doesn’t ship.
How we work
Synthesis, lyophilization, and fill are handled under controlled conditions, with independent cross-checks on quality control. Standard operating procedures are versioned and locked, and every chromatogram is reviewed before release. The chromatograms do the talking — browse current lot data on our Certificates of Analysis page and read more about our process on Quality Control & Standards.
