From Crash to Control: How Biohacking Gave Me My Life Back

What I Learned After 20+ Years of Chronic Injury, Peptides, and Self-Experimentation


I watched my father and younger brother die of heart attacks within four days of each other. I was 26 years old.


That kind of trauma doesn’t just wake you up. It rips the foundation out from under you and forces you to ask questions that doctors couldn’t answer. Questions like: Why did this happen to us? And more urgently: Am I next?


What followed was a multi-decade journey through chronic pain, surgeries, misdiagnoses, and pharmaceutical band-aids. At one point, I was a walking collection of injuries and conditions:

  • 9 years of plantar fasciitis that started at age 29
  • Ulnar nerve entrapment from jiu-jitsu, leading to surgery on both elbows
  • Neck injury diagnosed as degenerative disc disease, followed by corticosteroids, rhizotomies, and finally a C5-C7 spinal fusion
  • Vioxx-induced gut damage resulting in 12 ulcers
  • Steroid cataracts, Afib, and eventually Prinzmetal’s angina


If you had seen me, you would have thought I was much older than I was. And honestly, so did I. Then came the pivot point.


The Search for Something Better


While trying to help my teenage son heal from Osgood-Schlatter disease, I stumbled into research that mentioned peptides. What started as a curious Google search became a full-blown obsession with scientific papers, protocols, and experimental data. I vetted suppliers. I spoke to practitioners. I started stacking compounds. I became my own lab.

This wasn’t about optimizing six-pack abs. This was about walking without pain. About holding my kids without spasms. About waking up with enough energy to actually participate in my life.


N = 1: The Self-Experiment That Changed Everything


Biohacking, at its core, is the science of N=1. It’s not one-size-fits-all. It’s not guru worship or trend chasing. It’s structured self-experimentation using trackable inputs to get measurable outcomes.


My first major breakthrough? BPC-157 and TB-500. After almost a decade of tendonitis and failed physical therapy, these two peptides helped eliminate the pain in under six weeks.


The protocol I used:


  • BPC-157: 250 mcg daily, subcutaneous in the area of pain
  • TB-500: 2 mg twice weekly


I cycled it for six weeks, then paused for two. No side effects. Just relief I hadn’t felt in years.


Since then, I’ve used peptides and precision supplementation to:


  • Heal a rotator cuff to 80% functionality
  • Eliminate gut inflammation
  • Reduce blood pressure to the point I no longer need meds
  • Lose fat and gain muscle
  • Cognitive improvements
  • Improve recovery, sleep, and focus far beyond what I thought was possible post-40

What This Blog Is (And What It’s Not)


Project Biohacking isn’t about hype. It’s not medical advice. It’s not a shortcut. It’s a living experiment focused on rebuilding and rejuvenating using tested, personalized, and experience-based strategies.


Here’s what you can expect:


  • Real peptide protocols, what worked and what didn’t
  • Supplement stack breakdowns
  • Self-assessment tools and symptom tracking
  • Deep dives into regenerative health, mitochondrial support, and hormone balance
  • Occasional insights from trusted naturopaths and clinicians


And always—a bias toward action and results.
