L-Arginine and L-Lysine stack. When?

[Sizzle]

im planning on stacking L-Arginine, L-Lysine, and ZMA to boost testosterone and release GH. ive heard that L-Arginine and L-Lysine should be taken within a few hours apart because they battle for the same receptors. i've already decided to take ZMA before bedtime. when should i take the Lysine and Arginine? also how much of each is sufficient?
