Can I sub egg protein for whey with Mass Maker?

[SVB99]

Hey guys, this is a quote off of Beverly's webpage:"Here are some of the methods we use:
Off Season Weight Gain : 3 scoops Mass Maker + 1 scoop 100% Egg mixed in just 10 oz water (43 grams protein, 45 grams carbs, 1 gram fat, 380 total calories. Many of our clients use this drink to gain up to twenty pounds in 4 weeks by first eating their whole food meal and then drinking this formula right after the meal. "
Guys, what I'd like to know is whether I can substitute some Optimum Nutrition whey protein for that egg protein with this BI Mass Maker stuff and still experience similar weight gains.(cost cutting measure) Now, I know that 20lbs is not possible for everyine(if anyone) but I should gain 10 lbs. though, right? Does egg protein make that much of a difference? Also, it doesn't specify whether I have to take this combination substance more than once daily?
Thanks,
Sam

The stuff is not the same, egg is in the body alot longer, where whey is taken up or wasted very quickly, so its best used around workout times. I have no idea where the 20/10 pounds came from, you don't seem to post anything about it?

You could gain 100 pounds if you wanted, its all dependant on you.

You can buy milk/egg proteins pretty inexpensively.
