Tirzepatide
60mg · £114.99
Tirzepatide is a dual agonist at the GIP and GLP-1 receptors. The pharmacology literature characterises it as an imbalanced and biased agonist rather than an equal one — Willard and colleagues reported in JCI Insight in 2020 that its activity is weighted towards the GIP receptor, with biased signalling at GLP-1.
It is supplied here as research material in 60mg and 120mg vials. Tirzepatide is a prescription-only medicine in the United Kingdom under other brand names, and nothing supplied by BSR is authorised or intended for use in people.
Mechanism in the literature
GIP and GLP-1 are the two incretin hormones, released from the gut in response to nutrient intake. Tirzepatide engages both receptors from a single molecule, and the reviewed literature treats that dual engagement — rather than either receptor alone — as the basis of its distinct profile.
The clinical literature on this compound is extensive and conducted under regulatory supervision. It describes an authorised medicine used in patients, not research material, and none of it should be read as guidance for anything supplied here.
Handling and reconstitution
Supplied lyophilised at 60mg and 120mg. Allow the vial to reach room temperature, add bacteriostatic water down the wall of the vial, and swirl gently until the cake has dissolved. These are large vials, so establish the working concentration before reconstituting.
Storage and stability
Lyophilised at -20°C, protected from light, two-year retest date on the certificate. Reconstituted solution refrigerated and used within a short window; repeated freeze-thaw cycles degrade the material.
Common questions
What purity is BSR's Tirzepatide?
The current batch tests at 99.64% by HPLC against a not-less-than-98% specification, with LC-MS identity confirmation. The certificate reports related impurities, residual solvents, heavy metals, endotoxins and microbial limits, and its batch code matches the vial.
Is Tirzepatide legal to buy in the UK?
Tirzepatide is a prescription-only medicine in the United Kingdom. Material supplied by BSR is for laboratory research use only, is not for human or animal consumption, and is not an authorised medicine.
What is the difference between the 60mg and 120mg vials?
Quantity only; both come from the same batch under the same certificate. At £114.99 and £209.99 the larger vial is cheaper per milligram, but it is reconstituted as a single unit, so the choice depends on how much solution can be used within its stable window.
