Gonadorelin is synthetic GnRH — the master hormone controlling the reproductive axis. Primarily used as a TRT adjunct to maintain testicular function and fertility. Exogenous testosterone suppresses the HPG axis, causing testicular atrophy and infertility. Gonadorelin 2–3x weekly maintains pulsatile LH/FSH stimulation, preserving testicular volume and sperm production. A more physiological alternative to hCG for TRT patients wanting to maintain fertility.

Frequently Asked Questions
Q: Why use Gonadorelin with TRT?
A: TRT suppresses HPG axis → testicular atrophy and infertility. Gonadorelin 2–3x/week maintains LH pulses and testicular function.
Q: Gonadorelin dose with TRT?
A: 100–250 mcg subcutaneous 2–3x per week. Separate from testosterone injection days.
Q: How to reconstitute?
A: 2 mL BAC water + 2 mg vial = 1,000 mcg/mL. 100 mcg = 0.1 mL.
