Hey guys I just joined the group been on natural nootropics for years & first time I took modafinil/arma was a few months ago in a trial pack. Had a great experience & paired it with bromantane alpha gpc & l tyrosine. Before I buy more i wanna know what is the difference because I thought arma was supposed to last longer than modafinil but it was way shorter and i could still eat on it wheras modafinil was like 18hrs for me but curved my appetite. Why exactly is FL the best version?
