Weight & Metabolic

About Weight & Metabolic research peptides

Pepsup's weight and metabolic range covers the GLP-1, GIP and amylin research peptides at the centre of modern metabolic science, including Semaglutide, Tirzepatide and the triple agonist Retatrutide (often shortened to Reta). These incretin-pathway peptides are studied in the laboratory for receptor signalling and energy-metabolism research, and are supplied per vial as lyophilised powder for in-vitro and animal research only.

Every vial is third-party tested for identity and purity (99%+ by HPLC), sealed for transport and dispatched discreetly across the Netherlands, Belgium and the wider EU with tracked delivery. Whether your protocol calls for a single GLP-1 agonist, a dual GIP/GLP-1 like Tirzepatide, or a blend such as CagriSema, you can compare presentations, strengths and per-vial prices on each product page. All Pepsup metabolic peptides are sold strictly for laboratory research use and are not for human or veterinary consumption.
