Our Story

Built because
bad product
is inexcusable.

We launched Mr. Peptide because the research peptide market was — and largely still is — full of vendors who treat purity as a suggestion. We disagreed.

The Problem

Why we exist.

Research peptides are a legitimate and growing field of scientific inquiry. BPC-157 has hundreds of peer-reviewed studies. TB-500 has been studied in tissue repair since the 1970s. CJC-1295 and Ipamorelin are among the most researched growth hormone secretagogues in clinical literature. The science is real.

The vendors, however, have not always matched that standard. For years, researchers — from independent labs to universities to biohacking communities — have ordered compounds only to receive product that doesn't match its label. Underdosed. Contaminated. Mislabeled entirely. The absence of accountability was endemic to the market.

We built Mr. Peptide to fix that — at least for the customers who find us. Not with promises. With data.

"Every batch we ship has been independently tested. Not by us — by Chromate, a third-party analytical laboratory. The report number is on the COA. You can verify it yourself. That's the standard we hold ourselves to."

How We Operate

The Mr. Peptide standard.

01
Independent testing only.
We do not test our own compounds. Every batch goes to Chromate, an independent analytical laboratory, for HILIC-HPLC analysis with UV detection. The results are theirs, not ours. That independence is the point.
02
Every report is public.
Each COA includes a report number and a unique access code. Anyone — customer, researcher, skeptic — can enter that code at chromate.org/verify and see the original report. No PDFs we could have doctored. Direct from the lab.
03
One lab. Every batch.
We do not rotate labs to find the most favorable results. We use Chromate for every compound, every batch. Consistency in testing methodology means results you can actually compare over time.
04
The research is real.
Every product page on this site links to primary literature — actual PubMed-indexed studies on each compound. We want you to understand what you're working with. Informed researchers make better scientists.
05
We state what we don't know.
Research peptides are not FDA-approved drugs. Many are in early-phase research. We do not exaggerate clinical efficacy. What the studies say, we say. What they don't say, we don't invent.
06
For qualified researchers only.
Mr. Peptide compounds are sold exclusively for laboratory and scientific research purposes. Purchase constitutes confirmation that you are a qualified researcher. This is not a gray area we operate around — it is the boundary we operate within.

"I got into this market as a customer. I stayed because of what I found."

I come from a business background — over seven years in supply chain, sourcing, and distribution. I know how to evaluate vendors. I know what quality control looks like when it's real, and what it looks like when it's theater. When I started researching the peptide vendor landscape, I found a lot of theater.

Vendors citing purity claims with no testing behind them. COAs that were obviously templated. Companies with no verifiable address, no real contact, and customer service that vanished after the payment cleared. The market was serving researchers the way fast food serves nutritionists — technically food, technically a response to hunger.

I wasn't satisfied with that. Mr. Peptide is my answer to it. A catalog built deliberately. Every compound sourced with documentation. Every batch tested by a lab that isn't me, using a method that leaves no room for ambiguity, and published in a format that anyone can verify independently.

We're not the biggest vendor. We're probably not the cheapest. But if you care about what's actually in the vial — and if you're a serious researcher, you should — then this is where you belong.

Third-Party Testing

Why Chromate?

Chromate operates an independent analytical laboratory specializing in peptide purity analysis using HILIC-HPLC with UV detection — the same methodology published in peer-reviewed pharmaceutical research.

Critically: their reports are not issued to us. They are issued to us and simultaneously made publicly verifiable via a unique access code. You don't need to trust us. You can verify the result directly.
