2 big no
1. no mass gainer
mass gainer is not as good as it promised. The 1k calorie consists of 2 big washing powder scoop, which can be easily replaced by whey / banana / peanut butter, worse come to worst, icecream / milo / sugar, yield same calorie, same fullness, with so much less money to spent.
2. no gnc
overpriced supplement store next to direct sales

You can just buy whey + milo, or whey + icecream
it yield same macro with half of the price. idk how hard is it to mix whey with milo   
open ms excel, do the protein + carb vs price

**note**
- Milo 3 in 1 is more expensive than just milo powder in 2kg pack
- Mass gainer has very low serving per pack, dont get fooled
- Each serving of mass gainer is as big as 2 scoops of big washing powder
- Milo taste so much better

Mass gainer = whey + sugar
Milo = sugar
So, Mass Gainer = whey + milo

Problem solved ?

This is even cheaper

Yes its convenient to prepare store and consume. Also very convenient to get diabetes.

One big bag 10lbs only RM 300 but very less servings. One serving is like 2 huge scoops. 

I used to drink hell lot of Milo from my previous office cause its free. Not much difference bro.
