Quality Assurance · Certificates of Analysis

Every batch — independently verified.

Regena Peptides ships every reference compound with a batch-specific Certificate of Analysis from an independent ISO-accredited laboratory. HPLC purity, mass spectrometry identity, water/acetate content and endotoxin testing are all documented before a vial leaves our facility.

What's in a Regena COA

HPLC purity ≥ 98%

High-Performance Liquid Chromatography quantifies the percentage of the target peptide in each batch. Research-grade material reads 98%+ with a clean main peak.

Mass spectrometry identity

MS confirms the molecular weight matches the target sequence exactly — proving the compound IS what the label says, not a misfold or substitution.

Endotoxin & sterility

LAL endotoxin testing ensures bacterial contamination is below detection thresholds — critical for any in-vitro research application.

Independent ISO-accredited lab

Every COA on file is signed by a third-party lab — never the manufacturer. Independent verification is the strongest quality signal in the industry.

How to read an HPLC chromatogram

  1. 01Main peak height & symmetry. One tall, sharp, symmetrical peak corresponds to the target peptide. Tailing or shoulders suggest impurity.
  2. 02Area-under-curve %. The integration table reports the main peak as a percentage of total area — that figure is the purity. Anything under 98% is substandard for research applications.
  3. 03Identity confirmation. A separate MS spectrum should accompany the chromatogram, confirming the molecular weight (m/z) matches the target sequence.
  4. 04Batch traceability. A valid COA carries the batch number, manufacture date, retest date and signature of the QC analyst.

Red flags when a COA isn't legitimate

  • No third-party lab name or accreditation number on the document
  • Generic chromatogram reused across multiple unrelated batches
  • Purity reported without an integration table or visible peaks
  • Missing batch number, manufacture date or analyst signature
  • Vendor refuses to provide a COA for the specific vial shipped

Downloadable batch COAs

Real Janoshik Analytical reports for recent Regena batches. Click any row to open the signed COA image; every verify key can be checked at www.janoshik.com/verify. COAs may show different supplier names or letterheads because Regena uses multiple tested and verified suppliers — if one partner is out of stock, we source from another approved supplier so you always receive a verified batch.

Testing in progress

These compounds are currently at Janoshik Analytical / VidaLabs for independent HPLC + MS analysis. Batch-specific COAs are provided on request with every order.
