prohormones
Inactive hormone predecessors
Prohormones are precursor substances that the body converts into active hormones.
In endocrinology, this refers to naturally occurring compounds like proinsulin.
In bodybuilding and sports supplements, prohormones are synthetic compounds marketed to boost testosterone or other anabolic hormones: He stacked prohormones hoping to bulk up faster.
Many prohormones have been banned or reclassified as controlled substances.
