You don’t play at an elite level at 40 by guessing about your health. @CP3 uses data to understand what his body is telling him. Function members have access to 160+ lab tests. Know your numbers. Not medical advice. Consult a medical professional with any medical questions. For marketing purposes only.

They wanted to get their dream bodies before their wedding and surprise their families, so I offered them $250,000 and gave them all the resources they’d need! Go watch :D

Appreciate you sharing this. Out of range just means outside the reference range, not a verdict on your health. LMHR is a real pattern, and your diet shapes these numbers. Long-term risk is still being studied, so keep tracking your numbers and sharing them with your healthcare provider.

This morning when I woke up, I thought it was 7:30am, so when I took off my eye mask, I was surprised to find it was only 4:30am. But I felt awake. Not only that, I felt ENERGIZED. I have not felt anything upon waking other than utter exhaustion for at least a decade, but probably more like 16 years. Last week, I did Function Health Labs, which are super comprehensive. I started getting results back Saturday, fed them to a private AI, and it was freaking out about how I have no energy. YOU GUYS -- I'm a carnivore and I am ANEMIC. I have eaten red meat 🥩🥩🥩 for 99.99% of my meals for the last two and a half years, and I'm ANEMIC -- wth ferritin stores above 240! (This is so high, it was marked as dangerously high on Function Health.) It diagnosed me with anemia of chronic inflammation, which I hadn't heard of before, but it explained to me a question I had meant to ask a doctor -- why one iron marker was low when another was high and I was eating so much red meat -- but that doctor missed it because she preferred to spend our appointment time lecturing me about how I needed to eat greens even though I told her that eating this way was making me feel BETTER 🙄. (Pro tip if you're a doctor: if a patient who has been incredibly sick for over a decade tells you something they are doing is making them feel better, BE A HUMAN AND BE EXCITED FOR THEM and don't be a fucking idiot and tell them to go back to eating the way that made them feel worse.) I spent all weekend talking with the AI about my lab results, and it told me which supplements to take, including a few I already had on hand that it said would help. The main one it said I needed I had to order, and it will arrive next week, so I haven't even been able to take the most important one yet. DESPITE THAT, just taking the one I had lying around for the last seven days allowed me to FEEL ENERGY UPON WAKING!!!! Is this what it feels like to be a normal human?!?!?! Feeling energy upon waking made me want to cry. I feel so gypped!!!! I can't believe I'm only 7 days into what I need to do to get over this, and I am not exhausted and fighting to get through the day 😭 If I weren't so fucking excited, I think I'd be crying, but seriously, WTF. Western medical doctors and the healthcare system are so fucked. Yay for comprehensive labs and AI!!!

Sara and Tre lost almost 160 pounds together. They finished knowing more about their bodies than ever before, and now, as newlyweds, they’re looking forward to 100 healthy years together.

Before it began, Function established a baseline with lab tests to see what was happening inside their bodies. Follow-up testing tracked heart, hormone, and metabolic markers, helping them understand what was improving and what still needed attention.
