USN Hyperbolic Mass- WHY?

I used hyperbolic mass, i had to halve the servings because the shakes were so damn thick. I drank 3 half servings a day and tried to eat as much as possible, I didn't feel particularly bloated or anything. I understand that it is a rip off because carbs are dirt cheap, but this is the only thing that has managed to put any weight on me, granted it was only a couple of pounds but I went through 8kg of the stuff. 
AND I didn't put any fat on! :D
 
but as it is such a rip off, anyone have any ideas as to some good products I should try next? 
Still desperately trying to put on weight, but possibly want to try something more "clean".
Any ideas?

Just buy some whey and some instant oats... 
 
Under £75 for 15kg from Myprotein (5kg whey, 10kg oats)
 
If you have 50g whey and 100g oats in a serving it'll last 100 days, 75p/serving
 
teaspoon of peanut or almond butter and some milk and you've got a good high calorie shake, not sure how much but I'd guess at nearly 1000 calories?
 
This is what I have mid-morning.

Haha, cheers, this is all the advice I ever get :P
was wondering though, if your looking for just lean muscle, do you need any carbs at all?
I only have a very basic grasp of the science behind nutrition. 

Depends what you look like at the minute? If you've got a decent size then you could just use whey sort your diet out to reduce fat, but if you're a skinny kid wanted to get big then you'll need carbs

cheers,
I think I'll take your advice and buy some oats and protein from MP.
Possibly some creatine aswell

It's undoubtable the cheapest method mixing your own shakes, If you shop around you can get the whey cheaper, I was just using mp as an example as I know they do instant oats and peanut butter.
