Questions

Frequently asked questions

More answers in our full FAQ.

Are Port Peptides products for human use?

No. Every product is sold strictly for in-vitro laboratory research. Our peptides are not medicines, foods, supplements or cosmetics, and must not be used in humans or animals. We cannot give dosing, administration or preparation advice for human use.

How much does UK shipping cost?

UK shipping is a flat £3.80 and free on orders over £100. Orders are packed discreetly and dispatched from the UK.

How do I place an order?

What is the difference between pen, refill and vial?

They are three presentation formats of the same research material. Vials contain lyophilised powder; the pen format is a pre-filled presentation and refills are replacement cartridges for it. Prices differ by format.

How pure are your peptides?

Our research peptides are specified at ≥99% purity, verified by HPLC and mass spectrometry. Certificates of analysis are available on request for every batch.

How should research peptides be stored?

Store lyophilised peptides sealed at −20 °C, away from light and moisture. Short-term storage at 2–8 °C is acceptable. See our storage guide for full laboratory handling information.
