Overview

Product details.

RT-3 20mg (GLP-3)

What the third receptor adds

The glucagon receptor is the differentiator. Sema (GLP-1 only) and TZ-2 (GLP-1 + GIP) leave it untouched. But glucagon receptor activation drives energy expenditure through hepatic and thermogenic pathways that neither GLP-1 nor GIP can access. Preclinical data shows that adding this third receptor target to the dual GIP/GLP-1 framework produces the most pronounced effects on metabolic parameters of any approach studied to date.

All three receptors are G-protein coupled and signal through cAMP/PKA cascades, but their tissue distribution and downstream effects are distinct. GLP-1 receptors dominate in the pancreas and hypothalamus. GIP receptors are concentrated in adipose tissue and the CNS. Glucagon receptors are heavily expressed in the liver. RT-3 reaches all three tissue compartments.

The incretin ladder: Sema vs TZ-2 vs RT-3

Heritage Labs USA stocks all three tiers. Sema is the selective GLP-1 agonist (31 amino acids, one receptor). TZ-2 is the dual GIP/GLP-1 agonist (39 amino acids, two receptors). RT-3 is the triple agonist (three receptors). Comparative preclinical literature documents a clear stepwise increase in metabolic parameter engagement as you move from single to dual to triple activation.
