What Is Biohacking?
A deep dive into the science of human optimization — hormones, peptides, longevity protocols, and data-driven self-experimentation. This is where biology meets engineering.
I've spent 20 years optimizing systems. Software systems, deployment pipelines, developer workflows. But in 2026, I turned the engineering lens on a different kind of system — the one running all the others.
My own body.
This post is the beginning of a new series on biohacking — the science and practice of optimizing human performance through data, experimentation, and medical science. I'm documenting everything as I go: the research, the protocols, the blood work, the results.
Not as a guru. As an engineer who reads the papers.
What Is Biohacking?
Biohacking is the practice of using science, technology, data, and self-experimentation to optimize your biology. It ranges from simple habits — morning sunlight, cold showers, tracking sleep — to advanced medical interventions like hormone replacement therapy, peptides, and stem cells.
The term has roots in Silicon Valley's transhumanist movement of the late 2000s, when engineers and entrepreneurs started applying the same principles they used to optimize code to optimize their bodies. Dave Asprey popularized it through Bulletproof Coffee and quantified self-tracking. Peter Attia brought medical rigor. Bryan Johnson brought $2M/year and 40+ daily supplements.
In 2026, biohacking has gone mainstream. Continuous glucose monitors on non-diabetics. Oura rings tracking HRV. Telehealth clinics prescribing TRT to men who five years ago wouldn't have known their testosterone levels. The tools that were once exclusive to the obsessed are now accessible to anyone willing to take their health seriously.
The Pillars
Biohacking isn't one thing — it's a framework with interconnected categories:
Hormonal Optimization — TRT, HGH, thyroid management. The foundation for men over 30 who want to maintain or improve body composition, energy, and cognitive function.
Peptide Therapy — Short amino acid chains that signal specific biological responses. GH secretagogues for growth hormone release. BPC-157 for healing. Semax for cognition. A rapidly expanding frontier.
Nutrition — Not dieting. Nutritional biochemistry. Understanding how your specific body responds to different foods, macros, and timing. CGMs have made this measurable.
Exercise Science — Zone 2 cardio for mitochondrial density. Resistance training for lean mass and longevity. VO2 max training — the single strongest predictor of all-cause mortality.
Recovery & Regeneration — Sleep optimization, cold and heat exposure, sauna protocols. This is where gains are actually made.
Cognitive Enhancement — Nootropics, neurofeedback, meditation, breathwork, light therapy. Optimizing the brain alongside the body.
Longevity & Anti-Aging — NAD+ precursors, senolytics, rapamycin, fasting protocols. The science of extending not just lifespan but healthspan.
Stem Cell & Regenerative Medicine — MSC therapy, exosomes, PRP. Colombia is a major hub — advanced medical infrastructure at 50-70% lower cost than the US.
Technology & Monitoring — Wearables, blood panels, DEXA scans, epigenetic age testing. You can't optimize what you can't measure.
The Big Three: TRT, HGH, and Peptides
These are the interventions I'm most interested in, so let me give them extra context.
Testosterone Replacement Therapy (TRT) replaces deficient testosterone to restore mid-normal physiological levels (400-700 ng/dL). It's not steroids — the difference is like comparing caffeine to methamphetamine. TRT uses bioidentical testosterone at doses that mimic what your body should produce naturally. Steroid abuse uses 10-100x those amounts with synthetic compounds.
The 2023 TRAVERSE trial in the New England Journal of Medicine settled the cardiovascular safety debate: properly administered TRT does NOT increase cardiovascular events, even in men with preexisting heart disease. That was a landmark finding.
The catch: TRT requires commitment. Regular injections (twice weekly for stable levels), regular blood work (hematocrit, estradiol, PSA, lipids), and medical supervision. It's not a supplement you take casually.
Human Growth Hormone declines ~14% per decade after your teens. By 60, you're running on fumes. Synthetic HGH works — improved body composition, recovery, skin, sleep — but it's expensive ($800-5,000/month) and carries insulin resistance risk.
The smarter play for most people: GH-releasing peptides. Compounds like CJC-1295 and Ipamorelin stimulate your pituitary to produce its own growth hormone naturally. Lower risk, lower cost ($100-400/month), and you maintain your body's feedback loops instead of bypassing them.
Peptides are the frontier. Beyond GH secretagogues, there are healing peptides (BPC-157, TB-500), cognitive enhancers (Semax, Selank), anti-aging compounds (Epitalon), and fat-loss-specific peptides (AOD-9604). The evidence base varies widely — some have FDA approval, many are backed only by animal studies. Quality and sourcing are critical concerns. Work with a physician who prescribes through licensed compounding pharmacies, not random internet vendors.
Longevity Is Not Just About Living Longer
The real goal is healthspan — the number of years you live without chronic disease, disability, or dependency. Peter Attia's "Centenarian Decathlon" captures this perfectly: define ten physical tasks you want to be able to perform at 100, then train backwards from that vision.
The science has identified 12 hallmarks of aging, from genomic instability to chronic inflammation. The interventions target these hallmarks: NAD+ precursors (NMN, NR) restore cellular energy production. Senolytics (Dasatinib + Quercetin, Fisetin) clear senescent "zombie" cells. Rapamycin inhibits mTOR to promote autophagy. Metformin improves insulin sensitivity. Fasting protocols trigger cellular recycling.
And exercise — specifically Zone 2 cardio and VO2 max training — outperforms every pharmaceutical intervention for reducing all-cause mortality. Moving from poor to above-average VO2 max reduces your mortality risk by 5x. That's greater than the benefit of quitting smoking.
Safety First, Always
Here's where I'll be blunt: biohacking without medical supervision is reckless. "Natural" doesn't mean safe. "Worked for a YouTuber" doesn't mean it'll work for you.
My approach:
Comprehensive baseline blood work before touching anything — metabolic, hormonal, inflammatory, cardiovascular.
Qualified physician — endocrinologist or hormone optimization specialist, not a clinic that prescribes without testing.
Start conservative — lowest effective dose, one variable at a time.
Monitor aggressively — blood work at 3, 6, and 12 months, then annually. Track subjective markers daily.
Know the red flags — hematocrit over 54%, rapidly rising PSA, severe headaches, chest pain. These are stop-everything-and-call-your-doctor signals.
Living in Colombia is actually an advantage here. The country ranks 22nd globally in WHO healthcare rankings — the highest in Latin America — has INVIMA pharmaceutical regulation, and hosts world-class hormone optimization and stem cell clinics at a fraction of US pricing.
My Framework
I'm approaching this in phases, like any well-architected system:
Phase 1 — Foundation (Months 1-3): Comprehensive blood work. Fix deficiencies (Vitamin D, magnesium, omega-3). Lock in sleep protocol. Establish Zone 2 cardio and resistance training. Get a wearable for HRV tracking.
Phase 2 — Optimization (Months 3-6): CGM for 2-4 weeks to map personal glucose response. Evidence-based supplements. Cold and heat exposure protocols. DEXA scan and VO2 max test. If hormones are suboptimal — TRT conversation with a qualified physician.
Phase 3 — Advanced (Months 6-12+): Peptides under physician guidance. Epigenetic age testing. Longevity supplements based on data and research.
Phase 4 — Cutting Edge: Stem cell therapy. Senolytic protocols. Pharmacological longevity interventions. All under medical supervision.
I'll document each phase on this blog — the decisions, the data, the results, and the failures. Engineering applied to biology.
The system that runs every other system deserves to be optimized too.
