I travel 2-3 times a month within the US...in my experience pills the TSA doesn't care about and I have 3-5 bottles in my carry on all the time...anything powder will get your bag searched but thats just it, just a search and you will be on your way after..I have carried MRP packets and my alphamine in my carry on and I asked them what caused the search ..and TSA told me the powder..so now I just place my alphamine in one of those small holders and let it go through the xray on its own, they usually pick it up read it, shake it to make sure its powder and not liquid ad I am good to go, no more searches..same with the MRP's throw em in a bin just in case, as sometimes the MRP throws the TSA off sometimes it doesn't...so bottom line to avoid the delay/search leave pills in the carry on and take anything powder out and run it through seperate in the open in a bin...hope this helps
