I will be traveling to Hawaii in early September and i was wondering if anyone has had any trouble bringing supplements on the airplane. Most of the sups are Biotest and everything is legal. Just wanted to be sure before they threw things out because they are not allowed.
For carry-on, I've been fine with all of Biotest supplements, with the exception of Spike shooters or shotgun (no liquids over 3.4oz.) A while back, I had a five hour flight and brought a Spike shooter with me so I could get a bunch of work done on the airplane. They told me to either chug it or leave it behind. Oh, and if you poor your leucine into a ziplock bag, expect a couple of questions...
Actually I would not check the bag. You are most likely to have something confiscated in a checked back rather than having it in your carryon where you can explain to the person what it is. The only time that I have had items taken was when they were checked.
As long as the supplements are in marked containers or bags you will not have any problems - I have traveled dozens of times with numerous supplements, sometimes an entire gym bag full of them. I have also had protein powder and creatine in unmarked ziplock bags and was not questioned, even when I was searched at one airport where they took my peanut butter (which is apparently a "liquid").
Just be aware of the liquid regulations that were mentioned above.
