Thanks for the reply, so grateful for the important info..

As for Naked Whey, I could not find that in Indonesia..

I tried to find the most natural (grass-fed) whey protein and came up to this:

ISOPRO Grass Fed Whey Isolate - Puro

with their ingredients:
Whey Protein Isolate
Maltodextrin
Cocoa Powder
Choco Mocha Eclairs Flavor
Sucralose
Vitamin B6

and this:
Whey Protein Shake | Natural Protein Shake | The Protein Works™

both came from 100% grassfed beef, is that ok?

As for protein type, which one is better? Isolate or Concentrate? Or both is fine..

Thanks..
