From what I get, you're a female. Unless you're a super buff female which I don't think so.. 1 serving (2 scoops I think) of gainer and 2 scoops of ON whey with proper diet is a total protein overkill. You don't need that much protein a day.
Easy to hit high calories with a tight budget. Milk, oil and peanut butter helps a lot.

And 1 serving of mass gainer is another 50g. Assuming you don't eat much protein in your diet it's ok lah. But I bet there's at least another 70g coming from your meals. You'll be wasting your protein source only.
