About Peptide Labs

Peptide Labs supplies research-grade peptides to laboratories, universities and independent researchers across the United States. We started for a simple reason: sourcing peptides you can actually trust — with paperwork that holds up and a supplier who answers the phone — was harder than it should be. So we built the company we wished existed.

What we do

We source and stock reference peptides for in-vitro and laboratory research use only. Every catalog item is a defined compound with a published sequence, molecular formula and molecular weight, lyophilized and sealed for stability in transit. Our range spans metabolic research peptides, tissue-repair and recovery compounds, growth-hormone secretagogues, cosmetic and blend formulations, and the bacteriostatic water and supplies that go with them.

How we think about quality

Purity is not a marketing word here — it is a number on a document. Each batch is analyzed by reversed-phase HPLC for purity and by mass spectrometry to confirm identity, and a Certificate of Analysis is available for the lot you receive. We would rather omit a claim than overstate one: where a compound's public reference data is genuinely ambiguous, we say so on the product page instead of inventing a figure.

Shipping and support

Orders ship from within the USA, typically within one to two business days, in packaging chosen to protect the cold, dry state peptides need. When you have a question, a real person answers it — usually the same day. We are a small team by design, and we would rather earn repeat researchers than chase one-time buyers.

An important note on use

Everything we sell is intended for laboratory and research use only. Our products are not drugs, supplements or cosmetics, and nothing on this site is medical advice or a suggestion to use any compound in humans or animals. If that framing does not fit your work, we are not the right supplier — and we would rather tell you that up front.
