* The "Common Practice" column is an editorial generalisation, not a substantiated factual claim about any specific named competitor. Every Peptify column claim, by contrast, is independently verifiable — see the Certificate of Analysis on each product page, the Companies House register (PEPTIFY LIMITED #17021295), and the UK Intellectual Property Office trade mark search.
Plain answers to what researchers actually ask before ordering.
UK open banking is a bank-to-bank payment method regulated by the FCA. At checkout you select your bank, approve the payment in your banking app, and the funds transfer directly to Peptify — no card details shared, no third-party processor. The 90-second video below walks through it.
Every Peptify batch is independently tested by Janoshik Analytical, a third-party laboratory. Each batch ships with a downloadable Certificate of Analysis on its product page — including the HPLC chromatogram and 99%+ purity reading for that exact batch number. We never self-certify. If a batch fails our 99% specification, it is rejected at intake and never sold.
Yes. Research peptides are legal to purchase in the UK for research and laboratory use. Peptify products are sold strictly for legitimate scientific research and are not intended for human consumption. You do not need to prove your researcher status to order — by checking out you confirm the products are for in-vitro research only.
Three things separate Peptify: the Certificate of Analysis is on the product page (not on request), every batch is tested by Janoshik Analytical (not self-certified), and UK orders ship Royal Mail Tracked from London (not 2–5 days). PEPTIFY LIMITED is registered at Companies House (#17021295) and we publish full HPLC purity data openly — you can verify any batch before you order.
All Peptify peptides are sold exclusively for in-vitro research and laboratory use. They are not approved for human consumption, cosmetic application, or veterinary use. By purchasing, you confirm that you are buying for legitimate scientific research purposes only.
UK orders ship via Royal Mail Tracked from London. Most parcels arrive within 1–2 business days.

Yes. Every UK order ships in plain-label outer packaging — no Peptify branding and no peptide names visible, only a return address. Peptides are sold lawfully under UK research-use exemptions, and a research-use declaration is included in every parcel.
We accept UK bank transfer through secure open banking (FCA-authorised providers) and major cryptocurrencies — Bitcoin, Ethereum, USDT, USDC. We never see or store your card details, and your personal data is handled in full compliance with UK GDPR. You can request deletion of your account data at any time by emailing info@peptifyuk.com.
