What i do is have my Rx meds with the prescriptions (since i need them anyway) + on top of that i have three bottles of vitamins. Two of them are actually vitamins, one of them is a vitamin bottle with dbol or tbol etc. So even if someone checks your g2g. And if anyone ask's too many questions, just say: "doctor suggested etc." Few people are actually that interested and the ones that are will not risk their job unless they are very, very sure.
Example: once i had "beta-blockers" in a very suspicious package and it looked liked they were going to take them (or might) and i said: "so you are taking my heart meds. away from me before a long flight?" Answer: Ummm, no sir, go ahead...
(BTW. My heart is fine
