Frequently Asked Questions

Everything you need to know about our research compounds and ordering process

What are peptides?

Peptides are short-chain amino acid polymers that function as signalling molecules in biological systems. As research compounds, they are used in laboratory settings to investigate cellular mechanisms, receptor interactions, and biochemical pathways. All compounds supplied by Peptide Pal are strictly for in-vitro research purposes only — not for human use.

Are your compounds third-party tested?

Yes. Every batch is independently tested by accredited analytical laboratories using HPLC and mass spectrometry, confirming purity of 99%+ before dispatch.

Are you a UK-based company?

Yes. Peptide Pal is a registered UK company, based in the United Kingdom. We supply research-grade compounds to qualified researchers, laboratories, and institutions across the UK and internationally.

What is your shipping and packaging policy?

All research orders are dispatched within 1-2 business days in tamper-evident, temperature-appropriate packaging. Each shipment includes product labelling stating 'For Research Purposes Only — Not for Human Use' along with the relevant batch documentation.

How should research peptides be stored?

Lyophilised (freeze-dried) peptides should be stored refrigerated at 2–8°C, away from light and moisture — or frozen for long-term storage. Once reconstituted for laboratory use, solutions should be kept refrigerated and used within the timeframe specified in the accompanying product documentation.
