Metabolic Research

Metabolic research peptides represent a rapidly evolving class of metabolic research compounds studied for their effects on glucose homeostasis, lipid metabolism, and adipose tissue regulation in preclinical models. The compounds in this category act primarily on the incretin signaling axis — targeting GLP-1, GIP, and glucagon receptors to modulate energy intake, gastric emptying, and downstream metabolic markers. As metabolic peptides, they are of particular interest to researchers studying metabolic phenotype biology, insulin sensitivity, and body composition outcomes across multiple tissue types. All compounds are supplied as lyophilized, research-grade material for laboratory and in vitro use only.

Compounds in This Category

AT-R3 (Reta) — A triple receptor agonist targeting GLP-1, GIP, and glucagon receptors simultaneously, AT-R3 represents one of the most pharmacologically complex metabolic peptides in current research literature. Its tri-agonist profile allows researchers to study the additive and synergistic effects of combined incretin and glucagon receptor activation on energy expenditure, appetite signaling, and body composition outcomes. Available in 10mg, 15mg, 20mg, and 30mg lyophilized vials across a range of experimental dosing levels. See our AT-R3 (Reta) research guide for a closer look at its mechanism.

AT-T2 (Tirz) — A dual GLP-1/GIP receptor agonist that has been the subject of extensive published research on glycemic control, body composition regulation, and cardiovascular research markers in preclinical models. AT-T2’s dual-agonist mechanism makes it a valuable reference compound for researchers studying the independent and combined contributions of GLP-1 and GIP receptor activation to glucose homeostasis and body composition. See our AT-T2 (Tirz) research guide for more detail.

Research Applications

Researchers studying metabolic biology and body composition have used GLP-1 and GIP receptor agonists across a wide range of experimental systems. Common applications include glucose homeostasis and insulin sensitivity studies in rodent models, body composition research examining adipose tissue and lean mass measures, lipid metabolism investigations covering triglyceride and LDL dynamics, and gastric emptying rate studies relevant to appetite regulation research. The incretin pathway — and its role in coordinating pancreatic, hepatic, and adipose tissue responses — remains one of the most active areas in metabolic peptide research, with single, dual, and triple agonist protocols widely represented in the preclinical literature.

Documentation

Documentation availability varies by product and tested sample. Where third-party testing has been completed, Certificates of Analysis are linked directly from the individual product page — review the attached report for the exact product or formulation, since some products or vial sizes may not have matching analytical documentation. See our guide to reading a Certificate of Analysis for what each section does and doesn’t confirm. Products are supplied in lyophilized form for optimal shelf stability and shipped with discreet, temperature-appropriate packaging from our Pacific Northwest facility.

Storage & Handling

Lyophilized metabolic research peptides should be stored at −20°C and shielded from light and humidity prior to reconstitution. For detailed storage protocols and reconstitution procedures, see the Peptide Storage & Handling Guide, or browse the full Research Hub for additional compound guides.
