Real-world comparison of oral versus injectable semaglutide Fadini et al
Tirzepatide works on two receptors (GLP-1 and GIP), while retatrutide works on three, adding glucagon receptor activation
This is an area of active research and one of the primary motivations behind longevity-focused microdosing protocols explored later in this guide
Pharm Res, 2012, Vol 29(6), pp 14541467
Other GLP1 receptor agonists, such as Trulicity (dulaglutide), Wegovy (also semaglutide but at a higher dose for weight loss), and Victoza (liraglutide), offer similar mechanisms but vary in dosing frequency, cost, and clinical indications
Whether you are on compounded semaglutide drops or considering oral tirzepatide , the dosing frequency information here will help you get the most from every single drop
