The realistic middle is worth stating plainly
It plays a vital role in maintaining overall health
Molecular pathways documented in preclinical research include: (1) activation of nitric oxide (NO) synthesis via L-arginine/eNOS pathway, (2) transcriptional upregulation of VEGF-A and FGF-2 favouring angiogenesis, (3) modulation of the Egr-1 early transcription factor involved in fibroblast proliferation, (4) interaction with 5-HT2A and dopaminergic receptors in some behavioural models, (5) stabilisation of endothelial function via eNOS modulation and reduction of oxidative stress (8-OH-dG, MDA)
This mechanism relies on intact pituitary and hypothalamic function, making efficacy dependent on baseline hormonal reserve and individual receptor sensitivity
