About Catalyst Bio Labs
Science you can trust. Results you can verify.
A US-based research compound supplier built on a single idea: if you can't show your work, you shouldn't be selling research compounds.
Our Story
Built because this category needed it.
Catalyst Bio Labs was founded by researchers and operators who got tired of buying peptides that looked identical on the label and behaved differently in the vial. Compounds get repackaged from overseas suppliers. COAs get moved, edited, or invented. The researcher running the experiment is the one who pays for it.
We built a different kind of supplier. Every compound we sell is manufactured in our Texas facility under GMP-aligned practices, tested by Horizon Analytical — an independent US lab — and shipped with a lot-specific COA you can verify on the lab's own site.
If a batch doesn't pass, it doesn't ship. That's the whole pitch.
What We Stand For
Three things we won't compromise on.
Everything we do as a company comes back to one of these. If a decision conflicts with any of them, we don't make it.
Purity, first.
Every batch is HPLC-tested for purity. If it falls before our spec, it doesn't leave the facility. We'd rather lose a sale than ship a compromised compound.
Target purity — 99%+ minimum, 99.4% average
Transparency, always.
Every order ships with a lot-specific COA. Every COA is verifiable on Horizon Analytical's site. No edited PDFs, no "representative" documents, no marketing math.
COA of batches — published, verifiable
American-made, without compromise.
Manufactured, tested, and shipped from the United States. No overseas sourcing, no repackaging imported product, no "blended" supply chains.

Our Testing Partner
Tested by labs we don't own.
Every Catalyst batch is independently analyzed by Horizon Analytical, a US-based testing lab. They run HPLC purity, mass spectrometry, and LAL endotoxin testing — and they publish every result on their own site.
That means you don't have to take our word for anything. Pull up any lot we've ever shipped and verify it directly on Horizon's system.
