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
No established clinical contraindications
Standard reproductive endocrinology panels establish HPG axis baseline. LH and FSH confirm pituitary response to gonadorelin; testosterone, E2, and SHBG reflect downstream gonadal output.
Relaxin
No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.
