Frequently Asked Questions

What purity can I expect on delivery? Catalog items and custom projects alike ship at 99% HPLC purity or above. Each batch is checked by reversed-phase HPLC and cross-confirmed by mass spectrometry; the per-batch certificate of analysis in every shipment lists the measured purity, peptide content, and identity data.

What is the typical turnaround time? Stock catalog items ship within 24–48 hours of order confirmation. Custom synthesis typically takes 10–20 business days depending on sequence length, modification complexity, and scale; your feasibility review will include a firm timeline before you commit.

Do you support kilogram-scale production? Yes. Production scales from milligram research quantities through multi-gram pilot lots to kilogram commercial supply, using the same analytical release panel at every scale so data stays comparable across your program.

How do I confirm a product is genuine? Each label carries a batch-linked verification code. Entering that code in the COA lookup on this site returns the batch's certificate — purity, peptide content, sequence, and production dates — so authenticity is checkable in under a minute.
