High-Purity Peptide Solutions
For Serious Researchers
Every batch synthesized to ≥99% purity, independently verified by third-party HPLC and mass-spec analysis. Shipped cold, documented, and ready for the bench.
Featured Peptides
Purity is not a claim.
It’s a document.
Every lot we release ships with its own certificate of analysis from an independent US laboratory — HPLC purity, mass spectrometry identity, and net peptide content. If a batch doesn’t meet spec, it never reaches the catalog.
Built for the bench, not the shelf
Precision you can verify.
From synthesis to your door: lyophilized under nitrogen, stored at −20°C, and dispatched in insulated cold-chain packaging within 24 hours. Full COA and handling documentation in every box.
Trusted by working labs
The batch-linked COAs are exactly what our documentation process needs. Purity has matched the certificate on every lot we've independently re-tested.
Ordered Monday afternoon, on the bench Wednesday morning — still cold. The consistency between lots is the reason we stopped shopping around.
Support actually understands the products. They walked us through reconstitution documentation for an audit within the hour.
Frequently Asked
Every production lot is sent to an independent US laboratory for HPLC purity analysis and mass spectrometry identity confirmation. The certificate of analysis for your exact batch is included in your order and downloadable from the product page.
No. All Cactus Peptides products are sold strictly for in-vitro laboratory research and are not for human or veterinary use, consumption, or any form of administration.
Orders placed before 2 PM EST ship the same business day in insulated cold-chain packaging with gel packs. Most US orders arrive within 1–3 business days with tracking.
Lyophilized peptides should be stored at −20°C away from light and moisture, where they remain stable for years. Once reconstituted, store at 2–8°C and use within the timeframe noted on the batch documentation.
Due to the temperature-sensitive nature of research compounds we cannot accept returns, but if a product arrives damaged or fails to match its COA, we will replace it or issue a full refund — no friction.
