About Us

Thank you for visiting our website!

Peptex Laboratories was set up in 2014 to provide our customers access to the very latest in research peptides. We had grown tired of ordering from sketchy, unreliable sources, so we took it upon ourselves to research a suitable research establishment within Europe that could help us with our needs. This took some months, with many reluctant to help us but with persistence we managed to build a fantastic relationship with our current Research and Development centre.


We endeavour to primarily focus on two things with our business – provide the highest quality research peptides and chemicals to our customers and also provide the very best in customer service. Those who may have had to get in touch with an issue will know we go above and beyond, every time, to rectify any potential concerns.

While our business hours are Monday to Thursday 8am to 5pm, Friday 9am -12pm, UK GMT, we try to answer your emails outside of these hours but it can take longer during busy periods.

All of our peptides, unless otherwise stated are 98%+ in terms of purity (if this differs we will always note the purity level) We only supply the very best clinical grade research peptides and we also offer a selected line of GMP Receptor Grade Peptides for those working with larger surface areas that no longer fit in a Petri Dish.

We take pride in our ability to dispatch your order rapidly – within 24 hours or less (business days). Our products are manufactured in an GMP Compliant ISO9001 Certified Facility and our peptides are stored in a temperature controlled, continually monitored facility.


We aim to give you the very best products at the lowest rates. We may not be the cheapest around, but we remain competitive and feel that the quality of our products and the service levels we offer are unmatched. Some have said we are too cheap so our products must be inferior, but the opposite is true - we just don't want to take advantage of our customers in such a way where they are grossly overcharged.


Please take a moment to sign up and register with our site and in the footer, register for the newsletter, where we often send out discount codes and provide information on the latest peptides we have arriving with us.


We have a contact number - 07512395322 - but this can get spammed so can be off at times - your welcome to email us or, using the same number, WhatsApp us and we will be pleased to help.


We are UK based, we ship from the UK and we are pleased to confirm we ship worldwide. However we must add, it is your responsibility to ensure the products you purchase are legal for research in your country. Again we must stress that ALL products we sell are strictly for research use only.


If there are any specific peptides/SARMS/Nootropics/Research Powders you are interested in that may not be on the site, please email us at: sales@peptex-labs.com and we will do our best to help you but we must advise you that it is your responsibility to ensure any prododuct purchased is legal for research use in your respective country.
