OUR MISSION

Making quality peptides accessible — without the guesswork

We exist to give researchers a dependable source for reference-standard compounds — with the documentation, purity data, and traceability that serious lab work demands. No inflated claims. No mystery sourcing. Just characterized peptides, documented to the lot.

01

Transparent sourcing, stable supply

We work with vetted suppliers and maintain consistent stock levels so you aren't left waiting on back-orders or chasing down lot numbers after the fact.

02

99%+ purity as a floor, not a goal

Every batch is independently assayed. If it doesn't meet our minimum spec, it doesn't ship. The COA in your box reflects the actual vial you received.

03

A small team that actually responds

No call centers, no ticket queues. When you reach out about a lot report or a compound question, you're talking to the people who handle sourcing and QC.

— OUR STORY

We're not a big corporation.
We never wanted to be.

BiopepRx started when a small group of researchers got tired of inconsistent peptide quality and opaque sourcing. Too many suppliers made big promises with little documentation. Too many labs wasted time and budget on compounds that didn't meet spec.

We built a lean operation focused on one thing: reference-standard peptides with independent assay data on every lot. No warehouse churn, no mass-market scaling — just a compact team that sweats the details so your research doesn't have to.

HOW WE WORK

Four steps, zero guesswork.

From sourcing to your bench — here is exactly how every BiopepRx compound is handled.

01

Source & screen

Every compound is sourced from a small pool of audited suppliers. We run initial screening before committing to a batch.

02

Independent HPLC assay

We send every batch to a third-party laboratory for HPLC analysis. Results below 99% purity are rejected — not discounted.

03

Document & publish

A batch-specific Certificate of Analysis is generated. This is the report that ships with your order — not a generic template.

04

Cold-pack dispatch

Orders are cold-packed in plain packaging and dispatched within 2–3 business days, with tracking included.
