Questions people actually ask.

You don’t have to take our word for it. Every batch has a COA on file (Pepdor-commissioned HPLC) and a public batch record, and buyers submit vials to independent third-party labs - verified reports are published unedited in the Test Ledger, pass or fail. Check any batch record before you order.

Tracked shipping, typically 7-15 days to the US and EU depending on destination. Delivery issues are reviewed case-by-case based on tracking status, destination, and documentation. An EU distribution point for faster domestic delivery is planned.

Each batch is verified by Pepdor-commissioned RP-HPLC for purity and identity, through an independent contract laboratory. LC-MS identity, endotoxin, and sterility are reported per batch only where tested - anything not run is marked “Not tested” on the batch record, never assumed. Independent third-party results submitted by buyers are published alongside.

HPLC purity is the share of the vial’s peptide content that is the target molecule, by the stated method. It applies only to the specific batch and method shown and does not by itself establish identity, endotoxin, or sterility - those are separate tests, reported only where run. Chromatograms are on each batch record.

BTC, ETH, USDC, and USDT. At checkout we show the exact amount, an address, and a QR code. Card processing is not currently available for this category.

Store as stated on the batch record and product page. Lyophilized material is comparatively stable; solution stability depends on solvent, concentration, and laboratory handling. We do not provide reconstitution, dosing, or handling protocols - storage figures describe the material, not directions for use.

Yes. Order a batch, send a sample to an independent lab of your choice, and submit the report. Verified reports are published unedited in the public Test Ledger next to the batch COA, pass or fail, and once published are never edited or removed.

Materials are sourced direct from qualified synthesis facilities with a short chain of custody - fewer parties between the facility and the batch record - and every batch is documented and published in the public Test Ledger. The verification and the records are the product.

No. Everything Pepdor sells is a reference material for laboratory and analytical research only - not for human or veterinary use. We do not provide dosing, administration, or protocol guidance. Buyers are responsible for complying with the laws that apply to them.
