Characterised,
not just claimed.
Every vial ships with a batch-specific certificate of analysis and HPLC purity data. No mystery labels — the numbers are on the page before you buy.
Third-party verified
Independent lab HPLC on every batch, not a spot check.
Tracked UK dispatch
Tracked delivery to UK addresses. Minimum order £15.
Open-banking checkout
Fena bank-to-bank payments — encrypted, no card data stored.
Documented handling
Storage and stability data supplied with every certificate.
Featured research peptides
Reference figures shown per vial. Full COA available on each product page and with every shipment.
The certificate is the product.
Anyone can print a label. What separates a supplier is whether the peptide inside matches it — by purity, by net content, and by identity. We publish the data and let it speak.
HPLC purity, per batch
Reverse-phase HPLC on the exact batch you receive — the trace and percentage are on the certificate, not a stock figure.
Net peptide content stated
Purity and net content are different numbers. We report both, so you know the actual peptide mass in the vial — not just the salt-inclusive weight.
Mass-spec identity
Molecular weight confirmed against the target sequence so identity is not left to a label.
Handling & reconstitution notes
Laboratory reference material for qualified researchers. General handling only — no use guidance.
Bacteriostatic vs. distilled water
Choosing a reconstitution diluent for research storage, and why it changes shelf stability.
