CRH (Corticotropin-Releasing Hormone) vs Vasopressin

CRH (Corticotropin-Releasing Hormone) vs Vasopressin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

CRH (Corticotropin-Releasing Hormone)
Hypothalamic Hormone

Corticotropin-releasing hormone (CRH, also called CRF) is the primary hypothalamic regulator of the stress response and HPA axis. The 41-amino acid peptide is released from the paraventricular nucleus (PVN) of the hypothalamus and acts on pituitary corticotrophs to stimulate ACTH...

Vasopressin
Hypothalamic Hormone

Arginine vasopressin (AVP), also called antidiuretic hormone (ADH), is a 9-amino acid cyclic neuropeptide synthesized in hypothalamic magnocellular neurons and released from the posterior pituitary. AVP serves dual master roles: regulating water homeostasis via renal V2 receptors...
