How every batch earns its COA

STEP 01

Synthesis & purification

Peptides are synthesized and purified under GMP-compliant clean-room conditions with in-process controls.

STEP 02

Third-party HPLC testing

Random samples from every production run go to independent laboratories for purity and identity verification.

STEP 03

Lyophilization & cold storage

Verified batches are freeze-dried, sealed under inert conditions and held in cold-chain storage until dispatch.

  • Batch-specific Certificate of Analysis accompanies every order.
  • Insulated cold-chain packaging protects potency in transit.
  • Sealed vials with tamper-evident crimp caps and batch labels.
