Purity-Verified
High Purity Peptides UK
Every batch HPLC-verified — the purity figure on your COA is a measured value, not a marketing claim.
High purity is non-negotiable for research reproducibility. Every peptide we supply is verified at 99%+ purity by HPLC, with the exact measured figure recorded on the batch Certificate of Analysis.
99%+ HPLC Purity
Every batch is verified by high-performance liquid chromatography. The measured purity figure is recorded on the batch COA — not a marketing claim.
COA With Every Order
A batch-specific Certificate of Analysis ships with every order. Sample COAs are accessible from the COA library before you order.
UK Dispatch
Orders confirmed before the daily cut-off ship the same working day from our UK facility, with tracked next-working-day UK delivery as standard.
Research-Only Supply
All compounds are supplied strictly for in-vitro laboratory research. Documentation, labelling and packaging reflect that restriction.

Why MY PEPTIDES for UK research supply
Sourcing research peptides in the UK is harder than it should be. The market is fragmented across overseas re-shippers, unbranded suppliers and middlemen — most of whom won't show you a Certificate of Analysis, won't confirm HPLC purity, and won't tell you where the compound was synthesised.
MY PEPTIDES is built around the opposite of that. We dispatch from a UK facility, every product ships with the batch-specific COA, and our purity figures are the actual lab-recorded values. Researchers, university groups and trade buyers can order with the same confidence — wholesale enquiries are handled through our trade desk.
Frequently asked questions
- What does 99%+ purity actually mean?
- It's the percentage of the analyte peak in HPLC analysis — the measured fraction of the sample that is the target peptide.
- What is in the remaining <1%?
- Typically residual solvent, water, counter-ions and minor synthesis-related impurities — all documented on the COA where applicable.
- Why does purity matter for research?
- Reproducibility. Variable purity introduces unmeasured variables into your experimental data.
- How is purity tested?
- By high-performance liquid chromatography on every batch, with mass spec confirmation of peptide identity.
- Are stacks 99%+ pure?
- Each component compound in a stack is individually 99%+ HPLC-verified, with separate COAs for each.
