TRH (Thyrotropin-Releasing Hormone) vs Vasopressin

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

TRH (Thyrotropin-Releasing Hormone)
Hypothalamic Hormone

Thyrotropin-releasing hormone (TRH) is the smallest known hypothalamic releasing hormone, a modified tripeptide (pyroGlu-His-Pro-NH2) that stimulates TSH and prolactin release from the anterior pituitary. Despite its small size, TRH has extensive actions beyond the thyroid axis i...

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...
