Tirzepatide 40mg + Retatrutide 20mg Pen 3/mL | Made to Order | | When ordering please leave a note of how many pins you require.

This listing supplies a combination research peptide pen containing Tirzepatide 40mg + Retatrutide 20mg Pen — 60mg total net peptide content — as a made-to-order research peptide pen with a 3 mL fill volume, at ≥99% verified purity per component, for advanced laboratory research use. Tirzepatide is a dual GIP/GLP-1 receptor agonist and Retatrutide is a triple GLP-1/GIP/glucagon receptor agonist; together they are studied in comparative incretin, metabolic-regulation and energy-balance research within preclinical models.

Area of Interest Laboratory studies of these compounds have investigated a variety of areas in preclinical models:

• Comparative Incretin Research: Dual-agonist (Tirzepatide) versus triple-agonist (Retatrutide) signalling studied side by side under matched conditions.
• Metabolic Regulation: Studied in models of glucose control, appetite signalling, and energy expenditure.
• Weight-Management Models: Examined for effects on body weight and fat mass in preclinical animal models.
• Incretin & Glucagon Pathways: Investigated for activation of GLP-1, GIP and (for Retatrutide) glucagon receptors.
• Cardiometabolic Research: Explored for lipid metabolism, liver health, and cardiovascular parameters in research settings.
