Welcome to HCM
We understand your concerns
Height increases when bone length increases. Muscle has nothing to do with height except they give shape and posture to human body. Bome growth slowly stops at around the age of 23. then bone growth completely stops.
Therefore, that is truth and no medicine can ever increase height after bone growth stops. There is a syndrome with which human being grows till his death like Marfan syndrome
Don't unnecessarily loose your hard earned money.
