These data, combined with an automated analysis of whole-brain c-Fos activity showing sites with and without direct compound access, support a model in which semaglutide regulates BW by directly targeting independent brain regions
One hypothesis is that GHRP-6 and GHRP-2 have off-target activity at corticotroph cells or hypothalamic CRH neurons that ipamorelin lacks due to its modified structure
If you do not achieve adequate weight loss on semaglutide, your provider may recommend increasing the dose (if not already at maximum), switching to tirzepatide (which works through a dual mechanism), or adding complementary approaches such as hormone optimization or more intensive nutritional support
