https://en.wikipedia.org/wiki/18-Methyltestosterone
18-Methyltestosterone (18-MT) is an androgen/anabolic steroid (AAS) which was never marketed. Along with 19-nortestosterone (nandrolone) and 17α-ethynyltestosterone (ethisterone), it is a parent structure of a number of progestogens and AAS. These include the progestogens levonorgestrel (17α-ethynyl-18-methyl-19-nortes...

Drooling can be caused by excess production of saliva, inability to retain saliva within the mouth (incontinence of saliva), or problems with swallowing (dysphagia or odynophagia). There are some frequent and harmless cases of drooling – for instance, a...
