Yeah, the true part I was referring to was his general statement that there are better ways to get cals, not his claim that they didn't help in your case.
Have you considered packing a few shaker cups filled with stuff to take with you to work? Then you'd just add water when it's time for the meal, which would give you a lot more flexibility in terms of what's in them and would probably save some money, too. Your main investment would be the protein powder, with the fat and carbs coming from stuff like olive oil and oats (grind up a big batch in a blender). They're dirt cheap and, as a bonus, are better than the types of fat/carbs in most weight gainers.
