Process

How it works.

Where the peptides come from, which lab tests them, what the Certificate of Analysis actually confirms, and how orders ship without announcing themselves. No claims — only the process.

Sourcing

Peptides are synthesized by a solid-phase peptide synthesis (SPPS) manufacturing partner whose facility is identified and whose lots are traceable by batch number.

Every batch is then tested independently once it arrives in our custody — see below.

Third-party testing

Every batch is tested by an independent third-party laboratory. The specific lot in the vial you receive is tested end-to-end, and the raw lab report is published — printed in the box and linked from the QR code on the label.

The tests performed on every batch:

  • HPLC — High-Performance Liquid Chromatography. Confirms purity as a percentage.
  • MS — Mass Spectrometry. Confirms the peptide is what the label says it is.
  • Kinetic LAL — Limulus Amebocyte Lysate. Measures bacterial endotoxin contamination.
  • Karl Fischer — Water content of the lyophilized powder.

If a batch fails any of the four tests, it does not ship.

Tests performed: HPLC purity · endotoxin (kinetic LAL) · MS identity · water content. The exact values for the specific batch you receive are printed on the COA that ships with the vial.

Reading a Certificate of Analysis

A Certificate of Analysis (COA) is the lab report itself, not a summary of it. The COA that ships with your order will look like this at a glance:

Batch

Endotoxin

Water content

The COA arrives in the box as a printed sheet with a QR code linking back to the raw PDF on our storage. The PDF is signed by the lab and dated. It is not something you have to trust — it is something you can verify by taking the batch number to the lab directly if you want to.

Shipping & discretion

Peptides ship in insulated packaging with cold-pack refrigerant. Delivery is via standard carrier, within a small business-day window.

Every parcel is shipped in a plain outer box:

  • No brand name printed on the exterior
  • No product category listed on the label
  • Neutral return address; the recipient's name is the only identifier on the label
  • No marketing inserts or referral cards inside

What arrives at your door does not tell your mailroom, your neighbor, or a delivery photo what you ordered.

Data & privacy

We collect the minimum information needed to ship an order. We do not:

  • Load third-party marketing pixels or ad-network trackers on this site
  • Sell, rent, or share your email or shipping address with any marketing partner
  • Retain payment records longer than legally required
  • Aggregate purchase history for behavioral targeting

Order confirmations are sent by email. Nothing else is. If you want a receipt, request one.

Products on this site are sold for research and educational purposes only. They are not intended for human or veterinary consumption unless prescribed by a licensed provider.

Some peptides are regulated as prescription substances in some jurisdictions and unregulated in others. Some appear on the FDA's compounding restrictions list. It is the buyer's responsibility to verify what is legal to receive in their jurisdiction before ordering.

Nothing on this site is medical advice. Statements have not been evaluated by the FDA. If you plan to use a peptide in a research context that touches human application, work under the supervision of a licensed clinician.
