What is Tirzepatide?

Tirzepatide is a 39-amino-acid synthetic peptide built on the native GIP backbone and engineered to also activate the GLP-1 receptor, with a fatty-diacid modification that binds albumin and extends its half-life to roughly five days. It is the active ingredient in approved medicines used for type 2 diabetes and chronic weight management.

This listing is Tirzepatide (10 vials × 30mg) from TFC Peptides (Tianjin, China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

By engaging both incretin receptors, tirzepatide is studied for enhancing glucose-dependent insulin secretion, suppressing glucagon release and slowing gastric emptying, with GIP-receptor activity proposed to add effects on adipose-tissue lipid handling beyond what GLP-1 agonism alone produces.

Research status

Tirzepatide has completed large clinical trials supporting its approval for type 2 diabetes and obesity, and continues to be studied for metabolic dysfunction-associated liver disease, cardiovascular risk and other endpoints, giving it a considerably deeper clinical evidence base than most experimental peptides. Research-grade material sold here is intended for laboratory study rather than the clinical product.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Handling & storage

Supplied as a lyophilized powder; store unopened vials at -20 C protected from light, and after reconstitution with bacteriostatic water keep refrigerated and use within the timeframe set by the study protocol.

Concentration check: adding 2 ml of bacteriostatic water to one 30mg vial gives 15 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

Is research-grade tirzepatide the same molecule as the prescription drug?

The active peptide sequence is the same, but the prescription product is manufactured, formulated and quality-tested under pharmaceutical regulatory standards for clinical dosing, while research-grade vials are intended strictly for laboratory use.

How does tirzepatide’s dual mechanism differ from a GLP-1-only agonist?

A GLP-1-only agonist activates just one incretin receptor, while tirzepatide adds GIP-receptor engagement, which researchers study as a source of additional effects on lipid metabolism and insulin sensitivity beyond GLP-1 activity alone.

How much Tirzepatide is in this kit?

10 vials of 30mg each. The lab testing section above shows what the brand’s tested sample actually contained, where a report exists.
