I am taking PrimalJaX, and it has L-Arginine in it, is it ok to take some extra L-Arginine pills at the same time?

Primal only has 500mg of arginine, I was thinking of taking an extra 500mg of arginine with it.

Also can I take DHEA at the same time as I take the PrimalJaX?

I know more about steroids than I do about these supplements. LOL

Primaljax has Horny Goat Weed, L-Arginine, L-Dopa, Tribulus, Macapure Maca, Longjax (Eurycoma), Bacopin, and Grape Seed Extract.

I was just wondering if the DHEA or extra arginine will interfere with the primal?
