FAQ
Frequently Asked Questions
Everything you need to know about our research peptides.
What purity are your peptides, and how is it verified?
Every BioSupply UK peptide is guaranteed ≥99% pure. Each batch is independently tested using HPLC and mass spectrometry, and a Certificate of Analysis (CoA) confirming purity and identity is included free with every order.
What is a Certificate of Analysis (CoA)?
A CoA is an official third-party lab document verifying your peptide's quality — purity percentage, molecular weight and identity confirmation. You can view the CoA for each batch on the product's lab report page.
How fast do you dispatch and deliver?
Orders placed before 3PM (Mon–Fri) are dispatched the same working day via tracked delivery. UK orders typically arrive within 1–2 working days in discreet, unbranded packaging.
How should I store the peptides?
Before reconstitution, keep vials sealed and refrigerated. After reconstitution with bacteriostatic water, store at 2–8°C, do not freeze, and use within 30–45 days for most peptides.
