Learn About How We Ensure Quality
From the initial stages of peptide synthesis to packaging and delivery, Scientipeptides implements the most stringent quality control standards to ensure that all peptides arrive in their purest and most stable form. Comprehensive in-process and release testing conducted within our GLP-aligned analytical laboratory confirms the sequential fidelity of every synthesized peptide with exacting precision. Employing state-of-the-art reversed-phase High-Performance Liquid Chromatography (RP-HPLC) for purity profiling and Electrospray Ionization Mass Spectrometry (ESI-MS) for molecular mass verification, we provide robust, scientifically validated confirmation of peptide identity, compositional accuracy, and chromatographic purity, ensuring full compliance with the most demanding research-grade specifications.

FAQs
What are Scientipeptides used for?
All Scientipeptides products are sold for research use only. They are not intended for human consumption, therapeutic, or diagnostic use. Our peptides are designed exclusively for controlled laboratory research, educational studies, or analytical testing. Every product label and supporting document clearly reflects this compliance standard.
Who is eligible to purchase peptides?
Scientipeptides products are available to qualified researchers, laboratories, and educational institutions. Purchasers must confirm the products will be used for research purposes only.
How should peptides be handled and stored?
Lyophilized peptides should be stored at -20°C and protected from light and moisture. Once reconstituted, peptides should be used promptly and stored according to the documentation included with each product.
Why do peptide vials appear nearly empty?
Lyophilized (freeze-dried) peptides often appear as a thin film or small pellet at the bottom of the vial. The milligram amount stated on the label is verified by HPLC and mass spectrometry regardless of visual volume.
