i dont think the oj is good at all post workout because it has too much table shugar. and that means tooooooo much fruictose. u only need some fruictose now and then in low amounts, but its terrible for post workout some theories say it inhibits glycogen storage so that is not good for post work out, alose fruictose goes straight to your liver glycogen not muscle glycogen. so just go for dextrose or and unsweetend cereal thats low in fiber with alot of processed quick digesting carbs
