99%+ Measured
99% Purity Peptides UK
Not a marketing number — the actual HPLC-measured value recorded on each batch COA.
99%+ purity is not a marketing number — it is a measured HPLC value recorded on each batch Certificate of Analysis. The remaining <1% is typically water, counter-ions and trace synthesis impurities.
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
- How is 99% purity calculated?
- Peak area of the target compound in HPLC, as a percentage of total peak area for the chromatogram.
- Why not 99.5% or 99.9%?
- Peptide synthesis purity above 99% is normal; figures vary batch-to-batch. We report the actual measured value, not a rounded marketing figure.
- Are stacks 99%+ pure?
- Each component compound in a stack is individually 99%+ HPLC, with separate COAs.
- What if my batch is below 99%?
- We do not release batches below our purity threshold. The COA shows the exact value for your batch.
- Is 99% pure enough for research?
- For most published research protocols, yes. Always check the protocol's purity requirement against your batch COA.
