About Us
Our story
9to5 Peptides was built out of frustration. As researchers and science enthusiasts, we kept running into the same problem — vendors who were vague about purity, slow to ship, and impossible to contact when something went wrong.
So we built the alternative. A peptide supplier that publishes certificates of analysis, ships same-day, answers emails within 24 hours, and never makes inflated claims about its compounds.
The name says it all — we run a tight, professional operation. No mystery sourcing, no gimmicks. Just lab-verified compounds, clearly labeled, shipped fast.
Our mission
To make high-purity research peptides accessible, transparent, and easy to order — for every researcher, every time.
We believe the research community deserves a supplier that holds itself to the same standards it expects from the compounds it buys.
Why 9to5 Peptides?
Lab-grade purity
Every compound is third-party tested to ensure ≥98% purity. We publish certificates of analysis so you can verify before you buy.
Discreet, fast shipping
Orders processed same-day and shipped in plain, unmarked packaging. Tracking provided on every order.
Secure & trusted
SSL-encrypted checkout, multiple payment options, and a customer support team that responds within 24 hours.
Research-first sourcing
All products are for laboratory research use only. Compounds are sourced from verified manufacturers and never repacked.
Customer Reviews
“Purity on the COA matched exactly. Fast shipping and great packaging. Will be my go-to for all peptide research going forward.”

9to5 makes it easy. Clean site, clear product info, honest about research-only use. That honesty actually made me trust them more.
— Sam W.
Ordered the Wolverine blend and the BPC-157. Both came with COAs and the reconstitution guide was super helpful.
— Jordan K.
By far the most transparent peptide vendor I’ve used. They clearly label everything and don’t make any wild claims.
— Priya M.
The GLP-3R arrived in two days. Packaging was cold, discreet, and professional. Already reordered twice.
