Built by someone
who needed it.
Halflife started as a personal frustration. It became the peace-of-mind tool everyone running a health protocol deserves.

I built Halflife because I was the person who needed it and couldn't find it anywhere.
I was running tirzepatide alongside BPC-157, CJC-1295, and ipamorelin — juggling three different apps, a spreadsheet for reconstitution math, and a notes app for injection sites. Every week I was manually calculating how active each compound was, when to inject, and how much to draw. It was stressful, time-consuming, and honestly exhausting.
I tried every tracker on the market. GLP-1 apps ignored peptides entirely. Peptide apps didn't touch hormones or GLP-1s. Nothing understood what it meant to run multiple compounds with completely different half-lives, dosing frequencies, and reconstitution requirements all at once.
So I built Halflife — not because I wanted to start a company, but because I wanted one place that just made sense of my protocol. Every compound half-life in the app comes directly from FDA prescribing information and peer-reviewed pharmacokinetic studies. The math is real. The peace of mind is the point.
What I wanted was simple: open the app, see where every compound stands, know when to inject next, and not have to think about it again. That's what Halflife does. And it's what I wish I'd had from day one.
Give everyone running a peptide, TRT, or GLP-1 protocol the clarity, confidence, and calm they deserve.
Managing a health protocol shouldn't require a pharmacology degree or three different apps. It should feel effortless — one clear view of every compound, every dose, every level. That's what Halflife is built to deliver, using the same pharmacokinetic math trusted by clinicians, simplified for everyday people.
One View for Everything
Every compound in one place — GLP-1s, peptides, TRT. See your active levels at a glance, track doses, and never lose track of a vial again.
Real Math, Not Guesswork
Every half-life value comes from FDA prescribing data and peer-reviewed pharmacokinetic studies. The curves you see reflect the same science used by clinicians — no estimates, no filler.
Your Data Stays With You
Your protocol data is stored on your device — not sold, not shared, not uploaded to a server. Private by design, always.
Working in telehealth, compounding, or research?
Halflife Labs works with compounding pharmacies, telehealth platforms, and peptide research teams who want better data on how real patients run stacked protocols. If you're building in this space and want to talk about what we're seeing across thousands of active protocols, we'd love to connect.
Stop guessing.
