GLP-2-TZ is a synthetic dual-receptor peptide with affinity for the GIP and GLP-1 incretin receptors, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is GLP-2-TZ associated with?

Published preclinical laboratory work in this class concerns GIP and GLP-1 incretin receptor signalling chemistry. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is GLP-2-TZ approved for human use?

No. GLP-2-TZ is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is GLP-2-TZ supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of GLP-2-TZ is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot BAV6Y2: 99.96% pure by HPLC, tested by Freedom Diagnostics on 21 Sept 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

How GLP-2-TZ works

A dual-incretin research peptide studied for hitting two metabolic receptors in parallel.

GLP-1receptor agonist

Glucagon-like peptide-1 signalling is studied for glucose-dependent insulin release and appetite regulation.

GIPreceptor agonist

Glucose-dependent insulinotropic polypeptide is investigated for insulin sensitivity and nutrient handling.

Metabolic markersdual incretin

The paired receptor action is researched for combined effects on blood sugar, lipids and body weight.

What the studies found

Published findings on this compound, each linked to its source. Animal and lab results are context, not claims about this product.

Dual receptor designPreclinical

In the discovery work, this dual agonist switched on both the GIP and the GLP-1 receptor in cell assays, and acted through both receptors in mice.
