FAQ

Before you order

Which lot will I receive?

The lot shown in the buy box. It is printed on your vial label, and the same number opens its certificate in the lot register.

What is in the vial?

Tirzepatide as a dry, white powder sealed under a crimped cap. Nothing else is added.

When will my order arrive?

UK orders paid before 3 pm on a working day leave the same day by Royal Mail Tracked 24, free, and usually arrive the next working day. EU orders take 3 to 5 working days; the US and Canada 5 to 7.

Is Tirzepatide for human use?

No. Tirzepatide is sold as a research material for laboratory use only. It is not a medicine and is not for human or veterinary use. The library entry describes what published studies measured, not how to use it.

How do multi-buy discounts work?

Order 3 or more vials of the same product and size for 10% off each, or 5 or more for 15% off. The discount shows in the basket straight away.
