Best way to get Molly past airport security?

I'm flying out of NY (JFK) to Vegas (LAS) and I need advice on how to bring my Molly over without getting caught. I'm going with my girlfriend and she's thinking about putting the pills in a condom and shoving it up her vag, but I'm concerned about the potential of x-ray body scanners in JFK (Do they even use x-ray body scanners for domestic flights?). I read a few posts and was thinking about just throwing the pills in a OTC sup like 5-HTP and putting it in my carry-on. Any advice and/or previous experiences?
