Rather than supplements take natural sources u need to gain muscle I can help with 4-5 KGS muscle gain in month

It's a powder which is rich in protein and antioxidants... But these commercial products have their own side effects...try to eat skinned out boiled chicken 1-2 pieces twice a week, fish curry not fish fry as it is rich in vitamins, eat fresh raw sprouts everyday twice, include berries and fresh fruits like avocado,pears, apples, citrus fruits all this things are rich in fibres and vitamins.... Your morning diet should include whole egg and a glass of milk, try to repeat this in the evening also....include green leafy vegetables in your diet. Milk products like chesse,panner etc..these will be good and natural...regards.
