hi..thanks for the query.
My first advise would be determine carefully the components of the mass gainer you want you use.The aim of weight gainer products is to help supplement your diet with extra calories to add muscle mass. A variety of weight gainer products are on the market, with protein shakes
and protein bars among the most common. The formula used for weight gainers contains a high amount of calories, protein and carbohydrates that give you energy and meet or exceed your daily caloric intake need.They should not cause acne
You should check from your dermatologist
if you require to take isoace 20 anymore as there are possible side effects of the medicine like weight gain and lipid abnormalities if taken for a longer time.
Hoe this helps.Take care!
