Welcome to the forums! Glad you’re here to learn. We all are.
I’ve used HumaPro, but it’s essentially an EAA supplement. Not bad - but there are also egg white proteins available. Not sure if calories are the issue for you - but HumaPro has roughy 20 calories per scoop minimum (the protein blend is 5g of EAAs, 4 calories per gram of Protein, equals 20 calories).
The issue is, 5 total grams of protein is not enough to repair muscle tissue breakdown. Might be a good option to add a “little” protein to your diet, but 5g is not going to help you grow much, if at all. But hey, if you just like the product, then go for it.
You could end up losing muscle if you’re not supplementing with other forms of protein and trying to use this is an alternate to Fish, Chicken, Beef, and whey.
Enjoy PricePlow!
