Hello, I received my pilot slot this year as a 300. I'm scheduled to go to Wright Pat for my Flight physical soon and I wanted to know if anyone knew any information on it. My concern is that I'm a daily user of workout supplements like, whey protein, amino acids, glutamine, pre-workout supplments like; C4 Extreme. I've done some reading and found that having high levels of protein may be a red flag so I'm worried about how this would affect me at my physical. What are the tests done there that may be related to your body/blood levels. Does taking a lot of C4 cause any red flags? I know that a few years back C4 contained 1,3-Dimethylamylamine which will show up on a drug test as being positive for bad drugs. Thankfully, C4 have already fixed their pre-workout supplement and took that ingredient out so do I have anything to worry about? C4 is currently legit now since I've seen it sold at the bx but I still worry. I lift weights 4-5 times a week so I'm always on fitness supplements. I've decided to stop taking everything 2 weeks up to it and maybe it won't affect anything to be on the safe side.
