Custom Peptide Synthesis · Analytical-Grade Supply

About

A commercial peptide supplier, built on documentation.

We give commercial and research buyers a peptide supplier that ships the documentation, not just the powder.

The peptide market split, years ago, into two camps that serve commercial buyers poorly: pharmaceutical contract manufacturers built for ton-scale orders, and a long tail of resellers with little or no documentation. Cornerstone Peptide Co. was formed to occupy the ground in between — the quantities commercial and research buyers actually order, supplied with a full paper trail.

Our approach

We are the US commercial supply partner for an FDA-inspected peptide manufacturing facility. Orders are produced to specification, documented per lot, and shipped directly from the manufacturing partner with full documentation — the shortest chain between the synthesizer and your facility. We handle the customer relationship, technical support, account management and quality verification. The manufacturing partner’s identity is disclosed to qualified buyers under a confidentiality agreement.

Our operating principles

  1. i.

    We name our manufacturing partner only under mutual NDA. Identity is protected; qualifications are verifiable.

  2. ii.

    We do not synthesize molecules subject to active patent protection, and our catalog is silent by policy on FDA-approved drug substances and their analogs.

  3. iii.

    We supply active pharmaceutical ingredient and research material — bulk substance and lyophilized vials only. We do not supply finished or injectable dose forms; determination of intended use and regulatory compliance are the responsibility of the purchaser.

  4. iv.

    Every lot ships with a Certificate of Analysis, and any buyer may request independent third-party verification from Janoshik Analytical or Auxilium — at our expense for the first lot of any new substance.

  5. v.

    We respond to every qualified inquiry within one business day. Pricing, batch availability and our manufacturing partner's identity are disclosed to qualified buyers under confidentiality.
