I would imagine 4 weeks would be a waste of time, as far putting orals in a tylenol bottle the first things a customs agent would do (if your being searched) is look up the info thats stamped on whatever it is your actually bringing in. 0nce they see that its not tylenol in that bottle your azz belongs to them.
The DEA, Customs and even local LE have been dealing with this shit for a long time the chances of you coming up with a unique way of smuggleing something into the country has more than likely been tried countless number of times.
Go on vacation and enjoy yourself, screw the gear, its not worth your freedom.
