Tirzepatide

Tirzepatide activates two incretin receptors from one molecule, and the ratio matters: its affinity is weighted toward GIP rather than being evenly split. That imbalance is the experimental interest, because GIP and GLP-1 signalling produce different effects on insulin secretion and adipose tissue, and separating their contributions requires comparison against single agonists.

Research context

• GIP and GLP-1 receptor binding ratio and biased signalling
• Insulin and glucagon secretion under glucose challenge
• Adipose tissue GIP receptor activity
• Comparative work against selective GLP-1 agonists

Allow the vial to reach room temperature before opening. Reconstitute with bacteriostatic water introduced slowly against the vial wall — do not inject directly onto the lyophilized cake and do not shake.

• Store lyophilized at −20 °C, protected from light.
• Store reconstituted solution at 2–8 °C and use within the study window.
• Avoid repeated freeze–thaw cycles.
• Handle under standard laboratory practice with appropriate PPE.

Orders are dispatched same-day when placed before 14:00 local time. Compounds ship lyophilized and are shelf-stable in transit; packaging is discreet and tamper-evident with tracking on every order.

A lot-specific Certificate of Analysis is issued for every batch and is available from the lab results library.
