A family business built on proof, not promises.
ezPeps supplies meticulously tested research peptides to laboratories and researchers across the United States. Every batch is independently verified, and every certificate is public.
Who we are
ezPeps is a small, family-run supplier of research peptides based in Clinton Township, Michigan. The company was founded in December 2024, and we launched to customers in 2025 after months of careful market analysis, supplier vetting, and testing partner selection. We wanted to be certain we could deliver on our standards before we sold a single vial.
We are owner-operated, with no outside investors setting our standards. When you contact us, you reach the people who actually run this business and know the catalog cold.
Our legal entity is EZ Peps, LLC. We operate solely at ezpeps.com.
Why we started
The research supply market has a persistent trust problem. Certificates that cannot be checked. Purity claims with nothing behind them. Prices that bear no relationship to what is actually in the vial.
We built ezPeps to be the straightforward alternative, with an uncompromising commitment to transparency and genuine value for the research community. Rigorous testing you can verify yourself, honest pricing, and fast, dependable fulfillment.
We get it right because our reputation is the entire business.
How we test
Every batch we sell is independently tested before it reaches our shelves. Not a representative sample. Not once a quarter. Every batch, every time.
We name our laboratories, because a certificate you cannot trace is not verification. It is decoration.
Our primary testing partner is ILS Laboratories, an ISO 17025 accredited facility. We have also worked with these independent laboratories across our catalog:
Most of our certificates link directly to the issuing laboratory’s own portal, where you can confirm the result independently of anything we tell you. Every vial carries a QR code linking to its batch certificate, and our full COA Library is public, covering current and past batches.
Sourcing and testing
Our materials are predominantly American sourced. Our testing is 100% American, performed by independent laboratories in the United States.
We hold exacting standards for every lot we bring in, and we confirm each one through independent analysis rather than taking a supplier’s word for it. The certificate is the proof, and we publish it.
