Metabolic Research Peptides
Incretin-pathway research compounds — molecules engaging the GLP-1, GIP and glucagon receptors — studied for their effects on glycemic markers, hepatic lipid handling and energy expenditure in controlled laboratory settings. This is our most requested category.
Retatrutide (20mg)
Tirzepatide (30mg)
Retatrutide vs Tirzepatide — which to acquire
Retatrutide (20mg) — often shortened to reta — is a triple agonist targeting GLP-1, GIP and the glucagon receptor (GCGR). That third target is the broadest incretin profile currently under active investigation, and it is what drives the compound’s effect on energy expenditure. $119.00 per vial, or $5.95 per mg. Tirzepatide (30mg) is a dual GLP-1/GIP agonist with a substantially larger published research base. Researchers modelling comparative incretin activity commonly acquire both — the retatrutide listing carries a side-by-side receptor comparison table. $99.99 per vial.
Sourcing and supplier standards
We hold stock locally in the San Francisco Bay Area rather than drop-shipping, which is what makes same-day delivery possible and what keeps lot tracking straightforward. If you are evaluating suppliers, our guide to choosing a reliable research compound supplier sets out what to look for.
