Research peptides for the United Kingdom
myPEPT is a European supplier of research peptides that ships to the United Kingdom. The catalogue covers the compounds most searched for by UK laboratories and researchers: retatrutide in 5, 10 and 20 mg vials and in the pre-filled Reta Pen, BPC-157 and TB-500, the copper peptide GHK-Cu, tirzepatide in pen form, kisspeptin-10, PT-141 and the bacteriostatic water needed to reconstitute lyophilised material. Every batch is tested by an independent third-party laboratory and its certificate of analysis is published on the lab results page, so a researcher in London, Manchester or Edinburgh can check a lot number before and after ordering. Parcels to the UK ship from the EU with tracked delivery. Because the UK is outside the EU customs union, import formalities apply; see the shipping page for how these are handled. Customers in the UK can pay by card, PayPal, Klarna or SEPA transfer. All products are sold strictly for laboratory research use only and are not for human consumption.

Every product page states the format, the purity standard that applies and the lot number scheme used on the certificate of analysis.
How orders ship to the UK
Orders are dispatched from our European fulfilment location and every parcel to the UK is tracked. You receive a tracking link once the parcel is handed to the carrier and can follow it through to delivery. Lyophilised peptides are stable in transit, and bacteriostatic water and the storage case can travel in the same parcel, so most laboratories place one combined order.
The UK is outside the EU customs union, so parcels pass through import formalities on arrival. How customs and any related charges are handled is set out on the [shipping page](/en/shipping); please read it before ordering rather than relying on general assumptions. Enter the full UK address including the postcode at checkout. If a question about the address comes up, our support team contacts you before the parcel leaves.
Lab results and certificates of analysis
Each batch is analysed by an independent third-party laboratory. The certificate of analysis (COA) reports identity by mass spectrometry, purity by HPLC, the lot number and the test date. Certificates are published on the [lab results page](/en/lab-results), and the lot number on the certificate matches the lot number printed on the vial or pen you receive.
For retatrutide, BPC-157, TB-500, GHK-Cu and PT-141 the standard is at least 99% purity. For compounds without a stated threshold the measured value is shown on the certificate. Keep the certificate with your laboratory records alongside the lot number, so that every result in your lab can be traced to a tested batch.
Payment methods for the UK

- Card
- PayPal

Research use only: what it means for buyers in the UK
Every product sold by myPEPT is labelled and sold strictly for laboratory research use only. The compounds are not medicines, have not been evaluated for use in people and are not for human consumption. Product pages describe what each compound is and what it is studied for in preclinical research; they do not contain instructions for use in people and make no medical claims.
myPEPT does not give legal advice and makes no statement about the status of any compound in the United Kingdom. Buyers confirm at checkout that they are purchasing for research purposes and are responsible for complying with the rules that apply to them, including import rules. If you have a question about documentation or a specific batch, support can help; questions about how a compound might be used in people are outside what we can answer.
Supplies and the reconstitution calculator
Lyophilised peptides arrive as a dry powder and are reconstituted in the laboratory with [bacteriostatic water](/en/products/bac-water). The [peptide reconstitution calculator](/en/peptide-calculator) converts a vial mass and a diluent volume into a concentration in mg/ml so that stock solutions can be labelled correctly. It is a laboratory arithmetic tool and does not give any amount for a research subject. Pre-filled pens such as the Reta Pen and Tirzepatide Pen arrive ready for laboratory work without reconstitution.
