Triple receptor agonist (GLP-1 / GIP / Glucagon)
COP 490.000
Retatrutide (LY3437943) is a synthetic investigational peptide of 39 amino acids that acts as a triple agonist of GLP-1, GIP, and glucagon receptors. It is being studied in metabolic research, primarily in areas such as body weight regulation, liver fat (fatty liver), and glucose control. It is supplied as a 10 mg vial of lyophilized powder, intended exclusively for scientific research.
Retatrutide (development code LY3437943) is an investigational synthetic peptide composed of 39 amino acids. It belongs to a class of compounds known as triple agonists, as it interacts simultaneously with three metabolic receptors:
– GLP-1 receptor (glucagon-like peptide-1)
– GIP receptor (glucose-dependent insulinotropic polypeptide)
– Glucagon receptor
This combination, described in the scientific literature as "triple G" agonism, distinguishes Retatrutide from single and dual agonists. Due to its triple mechanism, it has become one of the most studied reference compounds in current metabolic research.
At KaiLab, peptides are supplied as a freeze-dried powder intended exclusively for scientific research. It is not approved for human or veterinary use.
These recommendations apply to all KaiLab freeze-dried peptides.
Freeze-dried powder (not reconstituted):
– Store at −20 °C for long-term storage.
– Protect from light and keep in a dry environment.
– Under these conditions it maintains its stability for extended periods.
Reconstituted (in solution):
– Reconstitute routinely with bacteriostatic water, under laboratory conditions.
– Store refrigerated (2°C to 8°C).
– Avoid repeated freezing and thawing cycles.
– Handle with aseptic technique and appropriate laboratory equipment.
These instructions pertain solely to the handling of research materials.
Retatrutide is the subject of study in metabolic research due to its simultaneous interaction with three hormone receptors. In the literature, it is primarily investigated in the following areas:
– Regulation of body weight and adipose tissue (body fat)
– Liver fat (fatty liver) and liver metabolic health
– Regulation of glucose and insulin sensitivity
– Energy balance and expenditure
– Comparative studies against single and dual agonists
