5 pills would be enough for anyone. Too much even I think. Especially Dutch pills, depends on the pill anyway but I remember getting gold bars and heinekens a few years ago that contained on average about 200mg of MDMA per pill. 5 of them and you'd be on your back. I don't think they're recommending or encouraging anyone to take or bring 5 pills but I just think they're specifying what's considered dealing and what's considered personal use.
