Genes First — every athlete's foundation
Nutrition strategies tailored to your DNA
Know exactly which supplements you need
This test is every athlete's foundation.
Before the program, the protocol, the supplement stack — there's your DNA. The 3X4 Genetics Test gives you the genetic blueprint underneath everything else, so the work you put in actually fits your biology.
Why Athletes Start With 3X4

"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."
