Gonadorelin

How it works

Unaltered GnRH, the brain's pulsed signal to the pituitary, sold to keep testes active on testosterone. Nonstop, it shuts them off.

What it's made of

10 amino acids: human GnRH copied unchanged. That is why it lasts very little time in the blood and only switches on the axis if it arrives in pulses, like the natural one.

What it's for

Prescribed for

Today, in people, nothing. It was approved to test the pituitary and, in a pulse pump, for fertility.

Sold as

The add-on to testosterone so the testicles do not shrink and you keep your fertility.
