What Tirzepatide Is
Tirzepatide is a single synthetic peptide that acts as an agonist at both the GIP receptor and the GLP-1 receptor. Its backbone is based on the native GIP sequence, modified so that it also activates the GLP-1 receptor. A C20 fatty diacid (eicosanedioic acid) is attached to the side chain of the lysine at position 20 through a γ-glutamic acid and two AEEA linker units. The fatty diacid binds serum albumin reversibly, which is why tirzepatide is described as long-acting in research models.
Published work characterises its comparative engagement of the GIP and GLP-1 receptors, the resulting differences in cyclic AMP accumulation and β-arrestin recruitment, and the pharmacokinetic profile conferred by fatty-acid acylation.

Choosing a Tirzepatide Vial Size
Every size is the same compound supplied to the same specification; the sizes differ only in how much material each vial holds. Larger vials carry a lower cost per mg, and the table above shows the current figure for each size. Smaller vials suit pilot work, or study designs that call for several separately opened vials rather than one large one.
Tirzepatide and Retatrutide
Retatrutide acts at the same two receptors as tirzepatide, GIP and GLP-1, and adds the glucagon receptor as a third target. Both are 39-amino-acid peptides that carry a C20 fatty diacid, so the two are often examined side by side in receptor comparison studies. Our retatrutide vs. tirzepatide vs. semaglutide comparison sets out the structural and receptor differences.

Frequently Asked Questions
What is tirzepatide?
Tirzepatide (LY3298176) is a synthetic 39-amino-acid peptide that acts as an agonist at the GIP and GLP-1 receptors. It carries a C20 fatty diacid that binds serum albumin reversibly.
What sizes of tirzepatide are available?
Tirzepatide is supplied in several lyophilized vial sizes. The table at the top of this page lists every size with its current price and cost per mg, and each size also has its own product page.
What purity is the tirzepatide supplied at?
It is supplied as a lyophilized powder at 99%+ purity, verified by independent HPLC and mass spectrometry testing.
How should tirzepatide be stored?
Store the lyophilized powder at −20 °C and protect it from light.
How is tirzepatide different from retatrutide?
Tirzepatide acts at the GIP and GLP-1 receptors. Retatrutide acts at both of those and at the glucagon receptor as well.
