Ghrelin Receptor (GHS-R1a) Selective Activation Ipamorelin acts as a highly selective agonist of the growth hormone secretagogue receptor (GHS-R1a), mimicking the natural hormone ghrelin without affecting other pituitary hormone secretion: Selective binding to GHS-R1a receptors without stimulating ACTH, cortisol, or prolactin release Rapid onset of growth hormone pulse generation (peak levels within 40-60 minutes) No significant effect on appetite stimulation unlike other ghrelin mimetics Preserved feedback regulation through endogenous growth hormone-releasing inhibitory mechanisms Research indicates that ipamorelin releases growth hormone with potency and efficacy similar to GHRP-6 (EC50 approximately 1.3 nmol/L) but with superior selectivity for growth hormone secretion
The mechanisms overlap with GHK-Cu but aren't identical
Indications: Guanethidine is no longer available in the USA due to lack of availability, but is available in the UK (wikipedia) Was used for severe cases of hypertension, either alone or as an adjunct drug Contraindications: Guanethidine can cause a hypertensive crisis in patients with pheochromocytoma due to the release of catecholamines (tyramine like action)
