About 22EXO

22EXO didn't start in a lab. It started in a conversation between people who came from completely different worlds — regulated industries, analytical chemistry, e-commerce logistics, and clinical research. What brought us together was a shared frustration: the peptide research market was full of inconsistency. Purity claims without data to back them up. COAs that looked like they were generated in five minutes. Suppliers who disappeared after the first order.

Some of us spent years working in heavily regulated manufacturing environments, where every milligram is documented and every process is validated. Others came from the startup side — building and scaling direct-to-consumer brands where customer trust is everything. A couple of us came from the research community itself — running protocols that demanded compounds with verified purity and full documentation.

We pooled those backgrounds and asked a simple question: what would a peptide supplier look like if researchers built it for researchers? The answer was 22EXO. We started with the workhorse research peptides — BPC-157, TB-500, GHK-Cu — and built outward from there based on what researchers actually use.

Based in Jessup, Pennsylvania, we built our operation around one principle — every product ships with the documentation to prove it's what we say it is. HPLC verification, mass spectrometry confirmation, and a Certificate of Analysis that actually means something. Not because the industry requires it, but because we'd want it ourselves. (See our quality program for the full pipeline from synthesis to shipment.)

We're building 22EXO to become the most trusted name in peptide research. Our roadmap covers GH research compounds like CJC-1295 + Ipamorelin, longevity peptides like Epithalon and NAD+, and two dozen other research-grade compounds — each one earning its place through rigorous analytical verification. We're just getting started.
