Serums
Source Player Core pg. 242
These are pharmaceutical serums; they're technological, or hybrid in some cases, but can be crafted using a laboratory and don't incorporate significant magic. You can activate a serum with an Interact action as you drink it or feed it to another creature. You can feed a serum only to a creature that's within reach and willing or otherwise so helpless that it can't resist. You usually need only one appendage to activate a serum.
