there are a lot of supplement stores in Belgrade , where do you live in Belgrade so I can tell you which one is close to you ?
no there is no health risks , whey protein i protein form milk , so its like drinking milk , in 1l of milk there is 30g of protein , if this 30g 80% is micellar casein ( also protein ) and 20% is whey protein , in cow milk , so like I said there is no risk , whey protein is even used in recovery after surgery and for patients with liver problems
I live in Požeška, near Roda Cineplex.
