prohormone
Inactive hormone form
A prohormone is a precursor substance that the body converts into an active hormone.
The thyroid and adrenal glands produce prohormones that become functional only after chemical modification elsewhere in the body.
In bodybuilding and sports, prohormones are supplements marketed as legal alternatives to anabolic steroids, though many have been banned: He took prohormones to build muscle faster.
