“With this test, I’ve unlocked the genetic edge to push my ultra-endurance limits—tailoring my nutrition, training, and recovery with pinpoint accuracy has been a total game-changer.”
Jenny
"I took the 3X4 test out of curiosity, not for health issues. The results helped my practitioner treat my skin condition, alleviate perimenopause symptoms, and lose 18 pounds. I'm grateful for 3X4, which has inspired me to learn more about my body and its unique environmental interactions."
Kaz
"I did the 3X4 Genetics test - I was able to verify some of the things I had already figured out through experimentation that worked for me. And in addition to that I was able to learn a few more things that I could add to my diet and my supplementation that would actually take my fitness to the next level."

“Knowing my genetics lets me train smarter, not harder. I've already tweaked my diet and lifestyle, and the results? I feel stronger, more energized, and my performance has been next level. And this is just the beginning!”

“After doing this test, I realized how much better I could’ve taken care of myself if I had this information earlier. Knowing exactly how your body works—what it needs, what to avoid—it changes everything. I honestly wish I had this at the start of my career. It would’ve made a huge difference in how I trained, how I recovered, and maybe even how long I stayed at my peak.”
Elaine
"I had been diagnosed with an aggressive, fast-growing form of breast cancer, but didn’t have an explanation what the cause was. Thanks to your tests’ guidance, I was able to achieve being in remission (less than 4 months after my 3X4 test results!)"

Can’t wait to see how 3X4’s genetic insights can help me make better personal health choices — and offer another layer of context to guide the individualized coaching we already do at ALTIS.
