Kyle opens up about his use of PEDs (steroids, testosterone, HGH) in college and talks about some of the misconceptions around them. Next, Kyle talks about his battle with depression and a close call with suicide that lead to life-changing experiences with psilocybin and ayahuasca—which really became the turning point in his own journey towards being more emotionally healthy, finding inner peace, and being a better husband and father. *DISCLAIMER: The substances spoken about in this episode are illegal and by no means are we advocating for anyone to use them or experiment with them.
