Well-tolerated in trials (87.5% AE incidence similar to placebo), with rare reports of headache, nausea, injection-site pain, or flushing; no significant cortisol/ACTH rises, but monitor for water retention or fatigue in sensitive models. – https://pubmed.ncbi.nlm.nih.gov/25331030/
Induces robust GH release (up to 7-10x baseline) without elevating cortisol, prolactin, or ACTH, even at high doses; rat studies show increased longitudinal bone growth (tibia length +8-12%) and body weight gain, suggesting potential for sarcopenia or growth retardation models – https://pubmed.ncbi.nlm.nih.gov/9849822/
Reduced HbA1c by -2.02% at 48 weeks in obesity trials; a Phase 1b study (n=72 T2D patients) showed dose-dependent fasting glucose drops (-1.5 to -2.5 mmol/L) via enhanced insulin secretion and glucagon modulation. – https://pubmed.ncbi.nlm.nih.gov/38367045/
Meta-analysis of Phase 2 data showed -42% to -60% triglyceride reduction, improved insulin sensitivity, and potential anti-cancer effects (e.g., 14-fold tumor volume reduction in preclinical pancreatic models via reduced obesity-driven inflammation) – https://pmc.ncbi.nlm.nih.gov/articles/PMC12026077/
