About Gonadorelin
Synthetic GnRH that binds pituitary GnRH receptors; pulsatile dosing stimulates LH/FSH release; used to maintain HPG axis during TRT
About Relaxin
Binds RXFP1 receptor, activating adenylyl cyclase and cAMP/PKA pathway. Upregulates matrix metalloproteinases (MMPs) to degrade excess collagen. Inhibits TGF-β fibrotic signaling. Promotes cervical softening and pelvic ligament compliance.

Gonadorelin
Standard reproductive endocrinology panels establish HPG axis baseline. LH and FSH confirm pituitary response to gonadorelin; testosterone, E2, and SHBG reflect downstream gonadal output.
