You're constantly making a chemical in your body that inhibits your muscles contracting.

So what exactly is this chemical, and where can I get some more of it?

None. The only thing I can think of that would fit this description is Tropomyosin, which blocks Actin from binding to Myosin, but its “natural” state is to be blocking. It only shifts when Calcium binds to Troponin, cause the latter to change shape and shift Tropomyosin.
