Your muscles become more noticeable to you in feeling in strength and to your brain aswell! Taste is great and mixing is brilliant, as long as you mix it for long enough! It is quite sweet ,which i like myself! But I think some people might find it a bit sickly! But! If you want RESULTS! I'D RECOMMEND GIVING THIS SUPPLEMENT SHAKE A TRY!
