Contact Us

We are a UK based supplier of research use compounds and we are glad to answer questions about strengths, formats, storage and dispatch before you order rather than after.

What We Can Help With
- Order and delivery questions. Dispatch times, tracking, and anything that has gone wrong in transit.
- Product information. Strengths, formats, storage requirements and current stock.

- Billing questions. Anything relating to payment or your order confirmation.
- Wholesale and bulk enquiries. Tell us volumes and we will come back with availability.
What We Cannot Help With
We cannot give medical advice, recommend amounts for human use, or discuss any use of our products outside laboratory research. Every product we sell is supplied for research use only and is not for human consumption. Retatrutide in particular holds no marketing authorisation from the MHRA, so no one here or anywhere else in the UK can lawfully advise you on taking it. If you want weight management treatment, speak to a qualified clinician about licensed options, which our comparison guide explains.
Response Times
Messages sent on a working day are usually answered the same day and always within one working day. Messages sent over a weekend are answered on Monday. If your order has already shipped and you simply want to know where it is, the tracking link in your dispatch email updates faster than we can reply.
Before You Contact Us
Many questions are already answered on our FAQ page, and delivery progress can be checked on the track order page. For pricing across every strength see the price guide, and for the legal position read the buyer guide. Checking those first usually gets you an answer faster than waiting for us to reply.
