Peptide Overview

What are research peptides?

Research peptides are short chains of amino acids used in vitro (cell culture) and analytical (mass spec, HPLC) research to probe biological pathways. They are strictly not for human or veterinary use.

How do peptides work?

Peptides are short chains of amino acids that act like highly specific messengers in the body: they bind to particular receptors on cell surfaces, triggering processes such as hormone release, metabolism changes, or tissue repair. Because each peptide’s sequence determines exactly which receptor it fits, researchers can use them to study and control biological pathways with great precision.

What is the difference between research peptides and pharmaceutical-grade peptides?

Pharmaceutical peptides meet clinical GMP and regulatory dossiers; research peptides (RUO) are tested for purity but not manufactured under clinical GMP or NDA requirements.

Are your peptides for in vitro research only?

Yes. All products are labeled “For Research Use Only (RUO)” and are not approved for human or animal administration.

Do I need a prescription to purchase research peptides from Genixpep?

No prescription is required. Our peptides are sold solely for laboratory research.

Testing & Quality Assurance

How do you test peptide purity and quality?

We employ a variety of tests to ensure our peptides are pure and contaminant-free
1. High-Performance Liquid Chromatography (HPLC): Confirms purity and weight.
2. Inductively Coupled Plasma Mass Spectrometry (ICP-MS): Confirms that our peptides are free from heavy metals.
3. Endotoxin Assay: Ensures our peptides are free of endotoxins, also known as lipopolysaccharides (LPS).

What is a Certificate of Analysis (COA) and how can I access it?

A COA is a lab report detailing test results (purity, mass, contaminants, etc). You can download a peptide’s most recent COA directly from the product page or browse all COAs in our centralized COA Library.


What purity levels do your peptides meet?

All peptides meet a minimum of 99% purity (HPLC).
