I just bought a Gainer cheap from my sister, since she didn't want it.
Should I take it instead of my Whey Protein-powder post workout?
Well, I am a hardgainer, and trying to gain weight (always had hard to gain weight), so now I got this cheap - so I thought, why not?

This gainer is this per serving, the bigger one (120 gram powder, 2dl) :
458 kcal (calories)
82 grams carbohydrates
29 grams protein
Smaller serving is like this (90 gram powder, 1,5dl)
344 kcal (calories)
61 grams carbohydrates
22 grams protein
Thanks in advance!
