Gonadorelin
LH/FSH support
GnRH analog — keep the HPTA awake while on TRT.
Research chemical vendors can't legally label products with the real name, so Gonadorelin often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:
- GnRH
- Gonad
Codes shown are for identification only. Always verify third-party COAs before purchase.
Bioidentical to the body's own gonadotropin releasing hormone. Pulsatile dosing tells the pituitary to release LH and FSH, which keeps testicular function online.
- Men on TRT who want to preserve fertility and testicular size
- Restarting the HPTA after a cycle
- More physiological than HCG because it acts upstream at the pituitary

The reconstitution math
- 1Reconstitute the 10 mg vial with 10 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 1,000 mcg/mL (1 mg/mL).
- 3For a 100 mcg dose, draw 0.100 mL — that's 10 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 100 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
