Their primary concern is managing their bottom line
It explains both its ~14.9% peak weight loss in STEP 1 and its dose-limiting nausea profile, gastric-emptying delay is the same pathway that drives upper-GI side effects
Therefore, the strongest current claim is that glucagon receptor activation may increase energy expenditure through hepatic and systemic metabolic mechanisms , but the exact human contribution of thermogenesis requires further study
Triple GLP-1 / GIP / Glucagon Receptor Agonist (CAS 2381089-83-2) Compound Name: Research Peptide (CAS 2381089-83-2) Classification: Research Peptide Multi-Receptor Agonist Description: This compound is a synthetic research peptide that functions as a triple agonist of the glucagon receptor (GCGR), glucose dependent insulinotropic polypeptide receptor (GIPR), and glucagon like peptide-1 receptor (GLP-1R)
IGF-1 can act over its putative receptor (IGF-1R) or it can also bind to the insulin receptor (IR), albeit with less affinity [9]
Also, eligibility varies widely by state
