About TXLABS
TXLABS supplies pharmaceutical-grade peptides and reference materials to laboratories, universities, and independent researchers. We exist for one reason: to remove the guesswork from sourcing research compounds. Every reference in our catalog is selected for identity, purity, and lot-to-lot consistency — then documented so you can trust what's in the vial.
We operate as a precision-first supplier. That means controlled synthesis lines, analytical QC on every batch, inert lyophilization, and cold-aware logistics. No anonymous reselling, no mystery powder. Just traceable material backed by data.
The numbers
- 102 reference compounds across 8 research domains (9 in stock)
- ≥98% HPLC purity standard (most lots exceed 99%)
- 24–72h typical dispatch after payment confirmation
- Global tracked shipping with re-ship guarantee
Quality & testing
Each production lot is characterized before release. Our standard analytical package covers identity, purity, and quantity so you know exactly what you're working with.
What we test
- Reverse-phase HPLC — purity by area %, against a ≥98% release threshold.
- Mass spectrometry (LC-MS) — molecular-weight confirmation of identity.
- Net peptide content — actual peptide mass vs. salts/water, so dosing in research is accurate.
- Endotoxin & appearance — visual and bioburden checks on reconstitution-ready material.
Certificates of Analysis
A Certificate of Analysis (CoA) is available for every catalog number. Request one before purchase to evaluate a specific lot, or with your order for your records. Email the catalog number to orders@txlabs.bio.

FAQ
Are these products for human use? +
No. All TXLABS products are sold strictly as research reference materials for laboratory use only. They are not drugs, supplements, or cosmetics, and are not intended for human or veterinary consumption, diagnosis, or treatment.
How do I read a catalog number? +
Each specification has a unique Cat. No. (e.g. RT10). It encodes the compound and size. Quote it in any CoA or support request for the fastest response.
Can I get a Certificate of Analysis before I buy? +
Yes. Email the catalog number to orders@txlabs.bio and we'll send the current lot's CoA.
How should I store the peptides? +
Lyophilized powder is stable for months at -20°C, desiccated and away from light. After reconstitution, refrigerate at 2–8°C and use within the validated window for your protocol.
What is your minimum order? +
There is no strict minimum, though orders over $300 ship free. Bulk and repeat-order pricing is available — contact us.
Do you offer bulk or wholesale pricing? +
Yes. For lab-scale or distributor volumes, email orders@txlabs.bio with the catalog numbers and quantities for a quote.
What happens after I place an order? +
You'll get an order reference on-screen and a secure invoice by email within 12 hours with payment and shipping instructions. We dispatch 24–72h after payment confirmation.
