About Peplogy

Precision in every vial.
Proof on every lot.

Peplogy exists to give researchers peptides they can trust — and the data to prove it. The integrity of your results depends on the quality of your compounds, so we built our whole operation around testing, transparency and reliable supply.

Our story

Started by people who were tired of guessing.

[Founding story — who started Peplogy, when, and why. Keep it specific and true: the problem you saw with research peptide supply, and what you decided to do differently.]

We focus exclusively on the research market. That lets us run a specialized supply chain built around chemical stability, temperature-controlled logistics and full technical transparency — so researchers spend their time on experiments, not on second-guessing their materials.

Today we supply independent researchers, academic institutions and private laboratories across the United States, and every one of them is verified before their first order ships.

What we stand for

Our commitments

  1. Integrity, verified

    We don't just claim quality — we publish it. Every lot has a public Certificate of Analysis you can look up by lot number.

  2. Built for research

    We supply laboratories, universities and research businesses — and verify every account before the first order ships.

  3. Transparent by default

    Sequences, specifications, test methods and handling notes are on every product page. No black boxes.

How every vial is made

From synthesis to your lab

  1. Synthesized

    Produced by solid-phase peptide synthesis and purified by HPLC.

  2. Independently tested

    Identity (MS), purity (HPLC), endotoxin and net content — by [Independent lab].

  3. Released by lot

    Only lots that pass every check are released, each with its own COA.

  4. Shipped same day

    Cold-packed, tracked and dispatched from the U.S. — COA in the box.

About Peplogy: A US Research Peptide Supplier

Research-grade peptides by Peplogy: vials in a laboratory

Peplogy is a US-based supplier of research-grade peptides and research compounds, operating from Dallas, Texas. We supply laboratories and qualified researchers with 83 compounds in vial, capsule, nasal-spray and topical-serum formats, and every Peplogy product is sold for laboratory research use only.

Every lot is characterized by HPLC for purity and by mass spectrometry for identity before release, and endotoxins are screened against USP <85> limits. The Certificate of Analysis for each lot is published in the Peplogy COA library and travels with every order.
