Sermorelin
Sermorelin (GHRH 1-29)
The first 29 amino acids of GHRH, representing the biologically active fragment. FDA-approved for GH deficiency in children and widely used off-label for adult anti-aging and GH optimization.
Mechanism of Action
Sermorelin binds to GHRH receptors in the pituitary gland, stimulating GH synthesis and release with a more physiological pulsatile pattern than longer-acting analogues.
