Frequently Asked Questions

Everything you need to know about ordering research peptides from PEPTIDE CENTRAL UK LTD.

Ordering & Shipping

This store serves the United Kingdom only. Orders are dispatched from our UK warehouse and delivered by Royal Mail, fully tracked, to any UK address: England, Scotland, Wales and Northern Ireland.

Standard delivery is Royal Mail Tracked 48 (2-3 business days) and express is Royal Mail Tracked 24 (1-2 business days), both fully tracked. In-stock orders placed before 2pm (UK time) are dispatched from our UK warehouse the same business day. Any item shown as pre-order dispatches once that batch lands. The date is stated on the product page.

Yes, free standard shipping on orders over £100, and free express shipping on orders over £200. Below those thresholds: Royal Mail Tracked 48 £6.99 (2-3 business days) or Tracked 24 £9.99 (1-2 business days). Signature on Delivery is a £0.77 add-on and is never waived.

You choose at checkout. Add Signature on Delivery (+£0.77) and your parcel is sent Royal Mail Tracked & Signed: it will not be left in a safe place, and if nobody can sign it is held at your local delivery office. Otherwise you accept safe drop, which authorises Royal Mail to leave the parcel in a safe place or with a neighbour; once scanned as delivered it is your responsibility and we cannot replace a parcel that goes missing afterwards.

We accept credit/debit card (Visa, Mastercard and Amex via Stripe), UK bank transfer and crypto. Card payments are charged at the listed price with no fee or surcharge; bank transfer receives a 4% discount and crypto a 8% discount, each itemised on the order summary before you confirm. Every price is in pounds sterling and no VAT is added at checkout, so the total you see on the final checkout step is exactly what appears on your statement.

Yes. Every order ships with fully tracked delivery. You will receive a tracking number via email once your order has been dispatched.

All sales are final. Returns are not accepted and change-of-mind refunds are not offered, due to the nature of research chemicals. If your order arrives damaged, faulty, or incorrect, contact us within 7 days via our contact page with photos and we will arrange a free replacement (or a refund if a replacement is unavailable). This does not affect your statutory rights. Full details on our Returns & Refunds page.

All orders are shipped in discreet, plain sealed envelopes with no branding visible on the outside. This ensures privacy and protects the integrity of the product during transit.

Yes, we offer pricing for research institutions and laboratories requiring larger quantities. Request a quote via our Bulk Orders page.

Quality & Testing

Purity is product- and batch-specific. For a single-compound product, the product page shows the available HPLC result for the listed batch. A blend does not have one meaningful combined purity percentage; where a blend report is available, it quantifies the individual actives by mass instead. Check the product page and COA Library for the current result and report status.

Published Certificates of Analysis are linked by batch in our COA Library when a report is on file. A batch still awaiting a public document is marked On request. Report contents vary by product and test method: a single-compound report may show HPLC purity and identity data, while a blend report may quantify its individual actives by mass.

High-Performance Liquid Chromatography (HPLC) is the standard analytical technique for determining peptide purity. It separates sample components under high pressure through a chromatography column. The resulting chromatogram shows the percentage of each component: the target peptide peak versus any impurities. A 99%+ result means at least 99% of the detected material is the target compound.

Published certificates identify the issuing third-party laboratory, the tested batch and the methods reported. The current library includes reports issued by Janoshik Analytical, published as received so the result can be checked. Report availability is shown separately for each batch.

Sourcing and manufacturing documentation is reviewed product by product rather than represented by one catalogue-wide certification. Batch-specific analytical evidence and available supporting information are shown on the relevant product and COA pages.

GMP (Good Manufacturing Practice) certification means a facility meets internationally recognised standards for the production, testing, and quality control of pharmaceutical and research-grade compounds. GMP facilities have documented procedures, equipment validation, staff training requirements, and audit trails.

Products & Research

They are supplied solely for lawful non-clinical in-vitro laboratory research. They are not licensed by the MHRA for medicinal use and must not be used in or on a human or animal.

Each listing describes the full catalogue identity, SKU, supplied quantity, physical form, stock and available batch documentation. Analytical results describe the sample tested and do not establish safety, efficacy or suitability for human or veterinary use.

No. We do not provide dosing, routes of administration, treatment, cosmetic-use or in-vivo protocols. Laboratory preparation, storage and handling must follow a validated institutional SOP, the applicable material documentation and a suitable risk assessment.

The catalogue may include bacteriostatic water as a separately identified laboratory reagent. Its presence in the catalogue is not a recommendation for preparing or administering any other item.

There is no minimum order. Free shipping applies on orders over £100. For bulk laboratory procurement, visit the Bulk Orders page.
