Homemade - I got really tired of paying big bucks for stuff out there.
I make my version of Austinite's pre - ( bottom of first post -

PRE-WORKOUT:
L-Citrulline Malate - 3 grams
L-Arginine (micronized) - 2 grams
L-Lysine - 2 grams
L-Methionine - 1 gram
I add 200mg caffeine and a little crystal light.
I multiply everything times 30, add enough boiling water to make 2.5 cups. I then put it in a water bottle clearly marked that it is dangerous and refrigerate. I take a cup or a shaker cup and pour in approximately 25 grams and add water to taste. 20-30 minutes later you are good to go. (this recipe I use 4 of the crystal light single serving packets that make 16 oz)
Do not throw the methionine pills in boiling mixture. They taste like complete crap and the gelatin from the pill casing gums everything up. Learned that the hard way.
Edit - added source for Austinite's recipe for pre.
