About Bench
What this is, who made it, and what it will not do.
What it is
v1.7A tracker for peptide, growth hormone and anabolic protocols. It holds what you are running, what you have actually taken, what is left in the fridge, what it cost, and whether any of it is doing anything: weight, bloodwork, how you felt.
The parts that are easy to get wrong are the parts it takes seriously. Reconstitution arithmetic is exact and covered by tests. Blends are split into their components and each one modelled on its own half-life. A U-40 barrel is never quietly read as U-100. And the 43 compound library tags every dose figure with where it came from, so an approved label and a forum convention never look alike.
Your data
There is no account, no server and no analytics. Everything you enter is stored in this browser, on this device, and never leaves it. Not to me, not to whoever is hosting it. The app makes no network requests of its own at all.
That is a real privacy guarantee and a real risk at the same time. Nobody can read your data, and nobody can recover it for you either. Clearing your browsing data erases it. Export a copy from Settings and keep it somewhere else.
What it tracks
- 43 compounds, with cited half-lives and dose ranges
- Protocols, titration ladders and adherence
- Reconstitution for U-100 and U-40 syringes
- Vial stock, beyond-use dates and cost per dose
- Injection site rotation
- Weight, with Android Health read-in
- 16 blood markers, charted against your doses
- Interaction checks across what you run together
What is new
v1.7A public page for the app, an About tab, and a light theme by default.
- A page at /landing explaining what the app does, with an illustration for each feature
- About is its own tab now, showing the version you are on and what changed in it
- Opens in the light theme the first time, rather than following the system. The toggle is on the landing page as well as in the app
- Buttons on a mint background are legible in dark mode again. White text on the dark palette's mint was close to invisible
- The mint vial icon on the web app and anywhere you install it to a home screen. The Android launcher keeps the icon it already had
- Movement on the landing page as you scroll, which stops entirely if you have asked your system to reduce motion
Anabolics and growth hormone, your own compounds, and a proper web app.
Import from other trackers, and bloodwork.
First Android build.
Who made it
Built by Arun, originally to track my own protocols properly, because every other option either wanted an account or got the arithmetic wrong. It is free, there is nothing to buy, and nothing about you is collected.

Where the numbers come from
Prescribing labels first, then published trials, then registries. Community practice is included where it is genuinely what people do, but it is always tagged as such.
Where a half-life has never been measured in humans, as with trenbolone and several research peptides, the app says so and draws no curve rather than inventing one that looks authoritative. Every entry links its sources.
