I'd like to gain weight and muscle. 17 amd 128 lbs. What brand of protein should i take. I've been taking GNC: Mass XXX for about 2 months. Whats the say on that. And I've been looking at other ones such as MRI Pro-NOS. what's the say on that.
Before you waste money on supplements...You need something to supplement.
Protein powder is good to have around, but if you want to gain weight you need real food. Keep it simple too. Eggs, meat, milk, bread, rice, potatoes, veggies, ice cream, and the Dollar Menu.
Get in a habit of keeping up with what you eat. Learn the calories and macro-nutrient breakdown of your favorite foods. Every day you should try to consume 2x your body weight (230 grams) in protein and carbohydrates and 1x your body weight (130 grams) in fat. As you gain weight bump up those numbers accordingly.
Once you do the above then you deserve to use supplements. Don't waste your time paying the "Weider Tax" just to figure out years later that some random person on the Internet gave you the correct advice on gaining weight
