GLP-3-RT is a synthetic research peptide in the incretin / GLP-receptor class, supplied as a lyophilised powder for reconstitution by qualified researchers. Peptides in this class are studied preclinically for their roles in metabolic signalling; it is provided strictly for laboratory research use only.

What is studied about compounds in this class?

Incretin / GLP-class peptides are investigated for metabolic-signalling pathways tied to glucose handling, appetite and body weight. GLP-3-RT is offered to support in-vitro and non-human research in that area; no human efficacy is claimed.

Is GLP-3-RT FDA approved?

No. GLP-3-RT is not an FDA-approved drug and has no approved human indication. It is sold strictly for in-vitro / laboratory research use only — not for human or veterinary use.

How is GLP-3-RT handled in the lab?

It is reconstituted in bacteriostatic water and used in in-vitro or non-human research models by qualified researchers. Handle under appropriate laboratory conditions and avoid repeated freeze-thaw cycles once reconstituted.

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

Every batch of GLP-3-RT is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot GC1XH9: 99.97% pure by HPLC, tested by Freedom Diagnostics on 05 Oct 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-3-RT works

A triple-incretin research peptide studied for engaging three metabolic receptors at once.

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.

Glucagonreceptor agonist

Glucagon-receptor activity is researched for its influence on energy expenditure and hepatic lipid metabolism.

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.

Weight lossClinical

−24.2%

In a 48-week phase 2 trial in adults with obesity, mean body weight fell 24.2% in the highest-dose arm versus 2.1% on placebo, and the reductions scaled with dose.

vs -2% on placebo

New England Journal of Medicine 2023 · phase 2 trial

Reported weight loss scaled with dose across the trial arms.

Who respondedClinical

93%

In the highest-dose arm, 93% of participants lost at least 10% of body weight and 83% lost at least 15%. On placebo those figures were 9% and 2%.
