Humapro Anyone?

To anyone who has used this product or something similar, is there a eaa to protein conversion?

How is it that people take it, lower their protein intake and lose fat but, not lose muscle?

I remember a while back members replaced most of their protein intake with Humapro with great success.

I looked at the stuff and it seems pretty unspectacular. 5g of aminos and a couple of common vitamins/supps. Nothing backing up some very bold claims.

I just don’t see it happening.
