Quality Assurance
Every batch.
Verified.
We don't ask you to trust our word. Every lot we sell is independently tested by an accredited third-party laboratory and backed by a certificate of analysis. Here's exactly how that process works.
Our Process
From synthesis to your door
Synthesis & Sourcing
Every peptide is synthesized using solid-phase peptide synthesis (SPPS) under GMP-aligned conditions. Raw materials are sourced from ISO-certified suppliers with full chain-of-custody documentation.
In-House QC Screen
Before any batch leaves the synthesis facility, an internal HPLC purity screen is run. Any lot below 98% purity is rejected at this stage — it never reaches our inventory.
Third-Party HPLC Analysis
Every accepted lot is sent to an independent, accredited analytical laboratory for high-performance liquid chromatography (HPLC) analysis. This confirms purity ≥99% and identifies any impurity peaks.
Mass Spectrometry Verification
LC-MS (liquid chromatography–mass spectrometry) confirms the molecular weight of the peptide matches the theoretical value within ±0.1 Da, verifying correct sequence and ruling out truncations or deletions.
Certificate of Analysis Issued
A full COA is generated for each lot number, documenting HPLC purity, MS confirmation, appearance, solubility, and storage conditions. COAs are available on request for every product we sell.
Lot Traceability & Storage
Each vial is labeled with its lot number, synthesis date, and expiry. Products are stored lyophilized at −20 °C until shipment, maintaining stability for the duration of the shelf life stated on the COA.
