Our Story

Built by Researchers,
For Researchers.

Alpha Peptides was founded on one principle: every vial that leaves our facility must meet the standard a researcher would set for their own bench.

We don’t dropship, we don’t outsource testing, and we don’t ship anything that doesn’t clear our 99% purity floor. Stocked and shipped from the East Coast. Independently verified by accredited US labs. Trusted by laboratories, academic institutions, and independent researchers nationwide.

Process

How a Vial Reaches You.

1. 1

   Sourcing

   Bulk peptide is procured from cGMP-aligned manufacturing partners. Identity is confirmed by HPLC and mass spectrometry before a lot is accepted into inventory.

2. 2

   Verification

   Each lot passes the five-test panel: Qualitative ID, Percent Purity, Quantitative Assay, Heavy Metals, and Conformity. Lots below floor are rejected outright.

3. 3

   Fulfillment

   Vials are lyophilized, foil-sealed, and packed cold-chain. Orders are dispatched within 48 to 72 hours from the East Coast with tracking issued at hand-off.
