L-Lysine and L-Argine

I would like to ask a few questions about supplements. I heard that taking L-Lysine and L-Arginine together does you no good, because they fight for the same receptors, but i have a load of L-Lysine left and I was wondering how long after taking Arginine can I take Lysine and get the maximum effects? I was also wondering if it was a good idea to take L-Arginine and L-Cartinine together? I have heard they work ell together why is this? Response on any of the questions will be helpful, even if it’s just one!

Thanks :up:
