DosisEvery dose, every vial, every pound — in one place.
Dosis is a private log for your peptide protocol. Record each injection in syringe units, see exactly what's left in every vial, and watch your weight and waist change over time.
No credit card to start · $4.97/month or $39.97/year after the trial · Cancel anytime
Built for people who actually keep a log
No spreadsheets, no notes app, no mental math at the fridge door.
Log a dose in seconds
Pick the peptide, set the units on a U-100 insulin syringe and Dosis shows the exact mg or mcg — with a syringe drawing so you can double-check before you inject.
Know what's left in each vial
Every peptide gets a vial that empties as you log. See mg remaining, doses left, and a warning when a reconstituted vial passes 28 days.
Never wonder “is it today?”
Set daily, weekly or custom frequency. The home screen tells you what's due today, what's late and what's coming next.
Weight & waist progress
Log in lb or kg, inches or cm. Interactive charts, goal ring, BMI and waist-to-height — with your doses overlaid on the timeline.
Reconstitution calculator
Enter the vial size, your dose and the units you want to draw. Get the exact amount of BAC water to add and save it to the peptide.
Library, assistant & PDF reports
A searchable peptide reference, an assistant for your questions, and a clean PDF of your doses, weight and waist to keep or share.

Good questions
Is Dosis medical advice?
No. Dosis is a personal record-keeping tool. It does not diagnose, treat or recommend any dose. Reference content is educational only. Always talk to a qualified healthcare professional before starting or changing anything.
How does the free trial work?
Create an account and use everything for 14 days. No card is needed. When the trial ends you choose the monthly or yearly plan to keep going — your data is kept either way.
I have a referral code. Where do I use it?
Type it in the “Referral code” field when you sign up. Your free period will be the one attached to the code instead of the standard 14 days.
Do I need to download anything from an app store?
No. Open Dosis in Safari (iPhone) or Chrome (Android), then use “Add to Home Screen”. It installs with its own icon and opens full-screen.
Who can see my data?
Only you. Each account has its own separate data, protected by your password. We don't sell or share it.
Can I cancel?
Yes, anytime — from the Subscription screen in the app or from your PayPal account. You keep access until the end of the period you already paid for.
