PI3K/Akt/mTOR and MAPK/ERK Pathway Activation In research settings, IGF-1 LR3 activates the PI3K/Akt pathway (involved in survival, glucose metabolism, and protein synthesis), the RAS/MAPK pathway (regulating growth and differentiation), the mTOR pathway (governing anabolic protein synthesis signalling), and IRS-1/2 cross-talk with insulin receptor signalling the full complement of IGF-1R-mediated downstream effects

The study concluded that both topical and oral glutathione are effective skin-lightening agents, with the combination therapy potentially offering superior results
Broader metabolic coverage Metabolic syndrome involves multiple interconnected dysfunctions: insulin resistance, dyslipidemia, hypertension, visceral obesity, and chronic inflammation
8 weeks 12 vials (10 mg) 56 daily doses needed
Evidence snapshot: The strongest available evidence is a small Phase 1 human trial (Teichman et al., 2006) showing dose-dependent, sustained elevation of GH and IGF-1 in healthy adults
