Why Peptify

What we do — anchored to verifiable facts. No marketing fluff, no claims we can't back up.

1. Independent HPLC per batch

Every batch is tested by Janoshik Analytical via HPLC. The signed certificate of analysis with the purity reading is downloadable from each product page — no request form, no NDA, no sales call. Browse the full COA library.

2. UK incorporation

PEPTIFY LIMITED is registered at Companies House under #17021295, incorporated 9 February 2026. Registered office: 37 Lombard Street, London EC3V 9BQ. Public and verifiable.

3. Honest stock

When a peptide is between batches we mark it out of stock on the product page. Join a queue with a single email and we send one notification when it's back from QC — no follow-up sequence.

4. Instant, card-free payment

Open Banking — an instant, FCA-regulated bank transfer approved in your own banking app, works with every UK bank — or cryptocurrency (BTC, ETH, USDC). No card details ever shared.

5. Same-day London dispatch

Orders placed before 1pm UK time ship the same business day from London via Royal Mail Tracked 24. Tracking number is in your inbox within hours of payment clearing.

6. Damage replacement, free

We don't accept returns on opened or unopened vials. But delivery risk is ours: a parcel that doesn't arrive is reshipped free within one working day of your claim under the Peptify Delivery Promise, and damaged parcels are replaced free — no restocking fee, no return forms.

7. Plain-English research framing

Every product page carries the for research use only disclaimer. No therapeutic claims, no dosing protocols, no banned language. Compliant with UK MHRA and ASA guidance.
