Hi Guys "N" Girls

I will get straight to it.

Vegan diets, Are they Optimal for Muscle mass, or can they be as good as a diet that includes meat.
Im old School, i always thought complete proteins from meat were the best source of protein.
Can a Vegan, make the same Gainz as a meat eater?

I should mention, theres a controversial young man on YouTube right now,(Vegan Gainz) Calling people out,
on their diets Among other things.

Whats your take on the Vegan Diet?
Or is it another Fad?

Thanks for your Opinions, and if there are any vegans here please throw in some input.

Sincere thanks goes out to you.
