Ensuring absolute purity through rigorous HPLC and Mass Spectrometry analysis. When your research demands precision, we deliver the data to back it up.
Every batch of SheerPeptides undergoes multi-stage independent testing. We provide full transparency into our synthesis process, so you can focus on the science — not the supply.
Each COA covers purity by HPLC, molecular weight by mass spectrometry, endotoxin screening, heavy metal screening, and sterility. It ships with your order and lives permanently on your product page.
Our mission is to bridge the gap between complex peptide synthesis and actionable research. By utilizing state-of-the-art lyophilization and purification techniques, we provide the stability and consistency required for reproducible results.
Every COA is public. Every batch traceable. We publish the full panel — not just purity — because partial disclosure isn't transparency.
99%+ means 99%+ confirmed by HPLC — not estimated, not interpolated. The data is in the COA and you are welcome to scrutinise it.
All products are sold strictly for in-vitro research use. We enforce this without exception and make it unmistakably clear on every product and shipment.
From initial sequence design to final cold-chain dispatch, our process is governed by strict quality control protocols. We don't just meet industry standards — we redefine them for the modern laboratory.
Your research and procurement data are secured with enterprise-grade SSL encryption. We never store payment credentials and never share your research details with third parties.
Pharmaceutical-grade amino acids and reagents sourced from verified suppliers only. Every incoming lot is documented and tested before it enters our synthesis pipeline.
Peptides are synthesised using SPPS in a controlled cleanroom environment with strict environmental monitoring and in-process quality checks at every stage.
Crude product is purified by preparative HPLC to achieve >99% purity. Analytical HPLC and MS confirm identity and purity before any batch is released for external testing.
Each batch goes to our ISO 17025 accredited partner laboratory for full panel testing. We do not self-report. We wait for external results before any release.
Lyophilised peptides are sealed under inert gas, labelled with batch and COA reference, and dispatched within 24–48 hours with full cold-chain protection where required.
