I'm following a creatine supplementation regimen and take 5 grams every day. Creatine is a white powder that might look to lazy bored teenagers or resentful proles like some illegal drug.
I don't have a doctor's note for this because creatine isn't some controlled substance, and I don't have a bottle with a "creatine" label on it because mine came in a large bag and I'll only need ~100g max.
Would I risk getting in trouble with the TSA or other airport authorities? How should I package the powder? Airports I'll be flying through include San Jose, Vancouver, Hong Kong, Phuket, Singapore, San Francisco and possibly Newark.
