EGGS are the standard that all proteins are measured against because eggs contain the best configured amino acid configuration that most closely fits your ideal protein digestion curve
when I was 24 years old, I gained thirty pounds in one year, stayed lean at the time, on a very high protein, lower carb diet. I was not taking any supplements at the time, and my energy was way down with the low carb level.however, I was never as lean as I was on that diet plan. I was very sick of eggs I'll tell you that, but I also must mention I lowered my reps and trained heavier, which definitely helped. good luck.
