Next to the magic store there is a store that sells only hormone pills. A form of pharmacy
.
The things they sell can boost or reduce a certain hormone.
They also sell medicines for injury but they have weird side effects that can last forever. However there is always an antidote but whether that antidote can be given is another matter entirely as it will always have side effects itself. The side effects given by the antidotes cannot be countered and often are permanent however.
Some of the hormones are laced and can cause unwanted effects or even death. And since the store is run by doctors there is no questioning of the medicines and hormones because they are all experimental.
But who will enter the store.
