Common questions
Before you order.
Are these peptides for human consumption?
No. Every product on ThePeptideCode is sold strictly for laboratory and research use only. They are not intended for human or veterinary use, diagnosis, or treatment.
How do you verify purity?
Every batch is independently HPLC tested for purity (≥99%) and confirmed by mass spectrometry for identity. Certificates of Analysis are published per batch on PeptideVerify and linked from each product page.
How fast is UK delivery?
Orders placed before 2 PM Mon–Fri ship same day from our UK facility via Royal Mail. Standard (Tracked 48, 2–3 working days) is £3.99, Express (Tracked 24, next working day) is £6.99 — free standard shipping over £100.
How should peptides be stored?
Lyophilised peptides are shipped under inert gas and remain stable at room temperature for short transit. Long-term: store at −20°C. After reconstitution, keep refrigerated at 2–8°C and use within the window listed on our dosage and storage guide.
What payment methods do you accept?
