Store peptides at -20°C upon receipt. For long-term storage, keep at -80°C. Always protect from light and moisture.

We offer multiple shipping options including standard (5-7 business days), express (2-3 business days), and overnight shipping. All peptides are shipped with temperature monitoring to ensure product integrity.

Yes, we ship to most countries worldwide. International shipping typically takes 7-14 business days depending on destination and customs processing. Customers are responsible for any import duties or taxes.

Peptides are shipped as lyophilized powders in sealed vials with desiccant. They are packaged with temperature indicators and insulated materials to maintain stability during transit.

We use Solid Phase Peptide Synthesis (SPPS) with Fmoc/t-Bu chemistry, which offers high purity and yield. This method is compatible with complex modifications and scalable from milligram to kilogram quantities.

All peptides undergo rigorous quality control including HPLC analysis, mass spectrometry confirmation, and amino acid analysis when required. Each batch comes with a comprehensive Certificate of Analysis.

Yes, we specialize in challenging sequences including hydrophobic peptides, sequences with multiple cysteine residues, long peptides (up to 100+ amino acids), and peptides with post-translational modifications.
