Hello there.  I can understand your concern.  What you need to build muscles is proteins and i wouldn't recommend any substitute to natural proteins like eggs, meat, milk etc. Eat more proteins and work hard, that way muscles will build naturally. Consult a general physician in person for further evaluation and management. Best regards. Dr. Anil kumar jain. Bangalore.

Hello....... It's better to avoid any kind of weight gain supplements... You can manage with diet itself.. Since those medicines can adversely affect health, They are not recommended.. Have egg ,meat ,fish, milk and milk products... Don't opt steroid medicine to gain weight.
