Re: Protein Shakes
Creatine gives nothing after you stop using it, you might lift more using creatine but after it you'll be back to your previous weights. Creatine doesn't stimulate muscles growth but just pumps it with water. Bodybuilding is time, 99% of supplements is useless.
Talk to anybody who didn't do roids and trains for at least 10 years naturally. My uncle is one of them, I also know tons of people who share my view.
Most of you is just deluded that something works. Roids might take you to the level you actually get bigger in the "natural way" much faster but not things like creatine and other stuff.
