please house I need drugs to make me add more weight am too skinny. Am 40 years old now but not comfortable with my skinny stature

Eat more and work less. Eat four times in a day and only once in the night, while reducing strenous physical labours. You don't really need drugs to get fat, except drugs that make you eat and sleep more. This is what worked for me.

You are 40 years old and so there is little that can be done most especially if you eat good foods, do exercises, genetics also has a huge role to play. To me, you don't need to add any weight, love your self the way you are. Please don't indulge in taking drugs, they could mess up your system and make you worse off.

I could have encouraged you start strength-training (weight-lifting) but i don't know about your energy level. But it is never too late to start your journey into beefing up your muscle-mass. I made a vow to gym till the day i drop dead.
