Are these products for human use? +
No. Everything sold by Puritas Lab is supplied for laboratory and research use only. It is not for human or veterinary consumption and is not intended to diagnose, treat, cure, or prevent any disease. By purchasing, you confirm you are a qualified researcher acquiring these materials for legitimate research purposes.
Where are your peptides made? +
All compounds are synthesized and tested in Florida, USA, and ship from our own Florida facility. We do not resell imported bulk powder — domestic synthesis is the basis of our quality control.
How do I verify purity and identity? +
Every batch is verified by RP-HPLC (purity) and mass spectrometry (identity) before release, and a Certificate of Analysis is included with every order. The lot number on the certificate matches the vial you receive. See Quality & Testing for how to read a COA.
How fast is shipping, and where from? +
Orders placed before 14:00 ET on a business day ship the same day from our U.S. warehouse via USPS Priority. Transit is domestic only — no customs delays. See Shipping & Returns for details.
How should vials be stored and handled? +
Lyophilized peptides should be stored at −20°C and protected from light. Sealed vials remain stable under these conditions. Compound-specific handling notes appear on each product entry. This is laboratory handling guidance, not usage instruction.
What payment methods do you accept? +
Standard card payment is processed securely at checkout. If a payment method is unavailable in your region, contact support for alternatives.
What is your return and guarantee policy? +
If a product doesn’t match its Certificate of Analysis, we’ll make it right. Full terms are on the Shipping & Returns page.
Do you offer bulk or institutional orders? +
Yes. For larger volumes, recurring orders, or institutional purchasing, reach out via Contact and include the compound and quantity.
