Ethyl-Ester-Creatine, which is better in pill form as it tastes like 
battery acid.

I hadn't thought of that.

I would be sceptical about arginine and methionine. Arginine can mess up 
your blood pressure, which might be a good or even pleasant thing 
sometimes, depending on your situation. Methionine can make you really 
sick if your methylic cycle is already messed (again depending on your 
individual situation, but a word of caution is never a bad idea).
