A 2026 UK review of the WHO ICD-11 definition, the messy cortisol/HPA-axis story (its not simply high cortisol), the synapse-loss biology, the HGF/c-Met synaptogenesis case and why rest, recovery and reducing the load come first, not a peptide Read the full review Neuroscience 28 May 2026 Dihexa for Autism Spectrum Disorder (ASD): MET Gene, rs1858830, HGF/c-Met, mGluR5 PET & the 2026 UK Review Rigorous 2026 UK review of Dihexa for autism spectrum disorder (ASD)
It is important to understand that this is a research-led hypothesis for risk minimisation and not a validated or even approved usage instruction
Research has examined its role in: 3-adrenergic receptor upregulation and adipose tissue sensitisation studies Lipolysis stimulation and plasma glycerol elevation in adipocyte models Lipogenesis inhibition and fat accumulation prevention in diet-induced obesity models Fat oxidation and energy expenditure pathway research Metabolic flexibility and substrate oxidation studies in obese murine models Cartilage regeneration and intra-articular joint biology in osteoarthritis models Safety pharmacology genotoxicity, bioavailability, and plasma kinetics profiling Comparative hGH fragment activity studies alongside AOD9401 and native hGH AOD9604 and Adipose Tissue Research In obese Zucker rats treated with oral AOD9604 at 500 g/kg body weight for 19 days, over 50% reduction in body weight gain was observed compared to controls, accompanied by significantly increased lipolytic activity in adipose tissue
The appropriate framing is that retinoids have stronger evidence, not that GHK-Cu has weak evidence overall
