About GLP-3 (RTA) 5mg
GLP-3 (RTA) is a multi-receptor incretin research peptide active at the GLP-1, GIP and glucagon receptors, and one of the most sought-after compounds in metabolic and incretin-pathway research. This listing supplies the 5mg lyophilized vial for laboratory research use. Every batch is tested to at least 98% purity by HPLC with a certificate of analysis (COA), is USA-made and third-party verified. For research use only; not for human or veterinary use or consumption.
Mechanism of Action
GLP-3 (RTA) is a single-molecule agonist active at three incretin-related receptors: the GLP-1, GIP and glucagon receptors. In preclinical systems researchers use it as a tool compound to study simultaneous multi-receptor incretin signalling and how combined receptor activity compares with single- and dual-agonist compounds. This describes a research mechanism only.
Preclinical Research
Multi-receptor incretin agonism has been examined in in-vitro receptor assays and animal metabolic-model research. GLP-3 (RTA) is used to probe how combined GLP-1, GIP and glucagon receptor activity behaves relative to single- and dual-agonist research peptides. All referenced work is preclinical and mechanistic; no human data or outcomes are implied.
Research Applications
Typical applications include comparative receptor-signalling studies alongside single-agonist (GLP-1 (SMA)) and dual-agonist (GLP-2 (TRZ)) research peptides and amylin analogs such as Cagrilintide, plus metabolic-pathway model work.

Protocol & Handling
This is a lyophilized (freeze-dried) vial. Reconstitute in the laboratory before study using a suitable diluent such as bacteriostatic water. Store the sealed vial frozen; keep reconstituted material refrigerated and protected from light. Handle only in a controlled laboratory setting. For research use only, not for human or veterinary use or consumption.

Frequently asked questions
What is GLP-3 (RTA)?
GLP-3 (RTA) is a single-molecule incretin research peptide that is active at three receptors: the GLP-1, GIP and glucagon receptors. It is supplied strictly for laboratory research use.
How does GLP-3 (RTA) work in research models?
In preclinical systems it acts as an agonist at the GLP-1, GIP and glucagon receptors simultaneously, so researchers use it as a tool compound to study combined multi-receptor incretin signalling. This describes a research mechanism only, not an effect in humans.
How is GLP-3 (RTA) different from GLP-1 and GLP-2 research peptides?
GLP-1 research peptides such as GLP-1 (SMA) act mainly at the GLP-1 receptor and GLP-2 (dual) peptides such as GLP-2 (TRZ) act at two receptors; GLP-3 (RTA) engages three receptors, which is why the three are often compared side by side in receptor-signalling research.
What format is this listing?
This listing is the 5mg lyophilized vial. GLP-3 (RTA) is stocked in a range of strengths, all linked in the specifications above.
Does GLP-3 (RTA) need to be reconstituted?
Yes. It is a lyophilized (freeze-dried) vial and is reconstituted in the laboratory before study using a suitable diluent such as bacteriostatic water.
What purity is GLP-3 (RTA) tested to?
Each batch is tested to at least 98% purity by HPLC and ships with a certificate of analysis (COA). It is USA-made and independently third-party verified.
What is GLP-3 (RTA) studied alongside?
It is frequently studied alongside single- and dual-incretin research peptides and amylin analogs such as Cagrilintide in comparative receptor-signalling and metabolic-pathway research.
Is GLP-3 (RTA) intended for human use?
No. It is sold strictly for laboratory and research use only, and is not for human or veterinary use, consumption, diagnosis or treatment.
