Founder, Project Biohacking

I'm Jeffrey Nunn — founder of Project Biohacking, an independent peptide education and coaching platform. My work focuses on the science, dosing math, and practical application of research peptides, with the goal of helping self-directed biohackers make informed, evidence-aware decisions in a market that often lacks both.

My background

I've been practicing personal biohacking and self-experimentation for over 30 years across lifestyle protocols, supplementation, nutrition, sleep, movement, mind-body work, and the decision-making frameworks that hold them together. Peptides are a more recent addition to my own stack, but I came to them with three decades of methodology already in place: how to evaluate evidence, how to read studies, how to design a personal protocol responsibly, how to track outcomes, and how to tell signal from hype.


I tell the full personal arc, what brought me here and how it unfolded, on my biohacking transformation story. The short version: after years of applying the same rigor to peptides that I'd applied to every other intervention, I built Project Biohacking to share what I'd learned and to provide the tools that didn't exist as a single trustworthy resource elsewhere, accurate dosing calculators, vendor evaluation frameworks, and one-on-one coaching.


I'm not a physician. I'm a writer, researcher, and practitioner with three decades of biohacking practice and an active habit of reading the underlying peptide literature. My work is built to help informed adults make better-researched decisions about research compounds. It is not a substitute for medical advice.

My approach

  • Evidence-aware, not evidence-only. I take peer-reviewed research seriously, and I'm also honest about where the published evidence ends and where practitioner experience begins. Pretending the line doesn't exist would be dishonest about the state of the field.
  • The math matters. Dosing errors are the single most common source of harm in peptide self-administration. The site's calculators exist because most peptide content available online gets the math wrong, sometimes by orders of magnitude.
  • Vendor transparency. I disclose all affiliate relationships, and I evaluate vendors on lab testing methodology, manufacturing origin, and supply chain integrity — not on commission percentage. When a vendor I review materially fails on quality, I say so.
  • Research-only positioning. The peptides covered on Project Biohacking are research compounds. I do not give medical advice, diagnose, treat, prescribe, or recommend specific compounds for specific conditions.


What I write about

  • Peptide science and mechanisms - how specific peptides work in the body, what the research actually shows, and where the evidence ends
  • Dosing calculations and protocols - accurate math, reconstitution methodology, and protocol design
  • Vendor evaluation and research-grade sourcing - what to look for in a research peptide vendor, lab testing standards, and supply chain
  • GLP-1 agonists and metabolic peptides - risk assessment, current regulatory landscape, and practical considerations
  • Self-experimentation methodology - applying scientific principles and decision frameworks to personal optimization
  • Biohacking decision-making - protocols for evaluating tradeoffs, avoiding common thinking errors, and managing the inherent uncertainty of self-experimentation
