it depends on your budget dude............honestly you shouldnt take in shakes or meal replacements unless its before and after a workout, on days off you should try and stick to just real food all day......but if your having shakes for budgetary reasons in between meals like Philosopher said.
but ideally id have it after a workout when you need some fast protein and carbs
what kind of meal replacements are we talking about but, they're are some good ones, but others are just cheap protein and sugar, and it makes a difference
I take it you're goal is to gain weight.
If your sensitivity to high macronutrients is poor, and fat gain is probable, I wouldn't take it before bed.
In addition to your meals, take it post-workout for comfort reasons and digestions reasons. It can be taken throughout the day. For me, I took my weight gainer whenever. It's personal preference.
agreed weightgainers = whey+multidextrin+dextrose+moderate dosage of fat
figure it out and its a waste of money, overhyped products shouldn't be a staple to your regime. To gain weight eat 250-500 calories over your daily needs, simple as that. Whole food meals consisting of quality protein, complex carbs and healthy fats are a must.
