Actually, I didn`t know that those are resistance symptoms (any way, are they?) besides I experienced them only once, two days ago when I used US track with headphones first time in my AM6 run. I asked about resistance because one user wrote that if you don`t experience it, you`re not growing with AM6 and I think he`s wrong. So, please, don`t make me a fool or liar, 4Kingdoms, and answer properly to this topic, if you can, of course, or be quiet.
