Dude… do you know how hard it is to gain muscle weight? lol… HARD. Yes, eating 4k plus calories a day IS hard… but thats just the way it is lol. Shit, I wish I could be 240 right now, but I probably wont see that weight for years and years if ever.
Weight gainers are def clean and a very good choice… Just keep in mind your body doesnt digest the total amount of protein, carbs, fats and calories… deduct about 25% off of what the nutritional facts are but STILL an exellent quick way to reach your 4k calories per day… and the shits cheap!!! You may not think so at $40 a jug but just think how much real food it would take to get those nutritional facts and the price of that real food.
