Founded by a scientist, 
peptides you can trust

Peptide Systems Founder CEO

Johnathon Anderson, PhD
Founder

Frustrated by the lack of high quality peptides available on the  market, we decided it was time for a change.

We extensively test each product in 3rd party, USA registered labs that have ISO 17025:2017 certification. 

So you have a source for research peptides that you can trust.

Premium Research Peptides

At Peptide Systems, we specialize in the synthesis and supply of ultra-pure peptides, proteins, and amino acid derivatives exclusively for non-human scientific research. Our mission is to deliver research-grade compounds that meet the highest industry standards for purity, potency, and safety, with transparency and trust at every step.

Precision Manufacturing

All peptides are synthesized in our state-of-the-art facility using a combination of solution-phase and solid-phase peptide synthesis (SPPS) technologies. This enables high-throughput production of complex peptides while maintaining exact sequence fidelity. Every batch is synthesized using automated peptide synthesizers for unmatched reproducibility and consistency.

Certified by Advanced Analytics

Each production run undergoes rigorous testing using:

High-Performance Liquid Chromatography (HPLC), to isolate and quantify peptide content and detect impurities. Mass Spectrometry (MS), to confirm molecular weight and structural identity via mass-to-charge ratio analysis. These analytical techniques ensure that every vial we ship is scientifically verified for identity, purity, and consistency, exceeding 99% purity standards. Furthermore, our peptides are independently tested and certified to be:

a. Sterile

b. Free of endotoxins (LPS)

c. Free of residual solvents and other contaminants

 

This makes them suitable for the most demanding preclinical and academic studies.
