PeptideBuddy models every peptide and GLP-1 dose on its own half-life, so you see how much is still active right now, when you'll clear, and steady-state accumulation. Build out your protocol with dosages, cycles, titration, and more. Log single shots or multi-compound blends, get the exact syringe units to draw, and set reminders. Free.
Hey Product Hunt 👋
I'm the maker of PeptideBuddy. I built it because I was doing reconstitution math in my Notes app and timing doses off a calendar instead of off what was actually still in my system, and it turned out a lot of people are doing the same thing.
PeptideBuddy does three things well:
🧮 Reconstitution calculator — enter your vial size, your BAC water, and your target dose, and it shows you the exact unit to draw on the syringe, plus doses per vial and cost per dose. It also catches the mg vs mcg mix-up, which is the error that's off by 1000x and the one that actually hurts people.
📉 Half-life tracking — it plots how much of each compound is still active over time, so you can see when you're at a real trough versus still riding the tail of your last dose. This turned out to matter most for people microdosing, where timing off your actual decay curve beats timing off a fixed schedule.
📋 Protocol management — build and track your full protocol in one place: dosages, cycles, titration schedules, and more. It keeps track of where you are on your titration ladder and what's due, so you're not rebuilding the plan in your head every week.
It's free, no signup needed to use the calculator. One thing I want to be upfront about: it's a math and tracking tool, not medical advice. It computes volumes, shows you levels, and organizes what you've decided to do; the dosing decisions stay with you and your provider.
I'm building this solo and the roadmap is shaped by what people ask for, so I'd genuinely love feedback: what would make this fit how you actually track your protocol? What's missing?
Thanks for checking it out 🙏

Who hunted PeptideBuddy?
PeptideBuddy was hunted by Mike DiCarlo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
