How Much Protein Do We Really Need for Muscle Growth?

I did talk to my doctor and he prescribed melatonin but twice packages came to the house ripped open and the pills gone. Mail around here is nuts these days at least 5 things we ordered in 5 weeks just don’t come. People have gone crazy! This is not the place to discuss sleep disorders , I should never have brought it up but Dr. Darden’s ZMA is helping. Thanks
