About AOD-9604

AOD-9604 stimulates lipolysis and inhibits lipogenesis through mechanisms believed to be independent of the insulin-like growth factor pathway. It appears to mimic the fat-metabolising action of growth hormone without triggering the proliferative effects associated with full GH or GH-releasing peptides. Oral bioavailability has been observed in some formulations, making it of interest for non-injectable protocols.

Research Areas

selective fat tissue lipolysis via GH C-terminal fragment mechanismadipose metabolism stimulation without IGF-1 elevationoriginally developed to isolate GH lipolytic effect from growth effectssubcutaneous injection — reconstitution with bacteriostatic water required

About Ghrelin

Must be acylated at Ser3 (by GOAT enzyme) for GHSR-1a binding. Receptor activation in the pituitary stimulates GH release; hypothalamic action via NPY/AgRP neurons increases appetite and reduces energy expenditure.
