Peptide Plug vs Dosio
Dosio is a broad personal-health tracker built around GLP-1 doses, with blood pressure, glucose, nutrition and hydration alongside the injection log. Peptide Plug is narrower and deeper. It does less general health tracking and considerably more vial and cost arithmetic.
Short version
Dosio is the stronger fit if you want one app for doses plus general health metrics: blood pressure, glucose, nutrition, hydration and progress photos. Peptide Plug is the stronger fit if you need reconstitution math, cost per dose, inventory and expiry, or lab overlays. Dosio has a free tier and a Pro subscription whose price varies by country; Peptide Plug publishes a flat $4.99/mo or $49.99/yr.

Where each one wins
Neither is better at everything. These are the honest trade-offs.
Pick Peptide Plug for
- You reconstitute vials and need the concentration and syringe math held for you.
- You want cost per dose, cost per month and a vial run-out date.
- You want inventory and mixed-vial expiry tracked together.
- You want a published, flat price rather than one that varies by region.
- You want free calculators you can use without installing anything.
Pick Dosio for
- You want blood pressure and blood glucose as first-class tracked metrics.
- You want nutrition and hydration logging in the same app.
- You prefer a native app and a free tier with full app access.
- You want daily insights tied to dose patterns across general health data.
Which should you pick?
If you want one app for GLP-1 doses and your general health numbers, Dosio covers more ground. If the hard part of your protocol is the vial math and the cost, Peptide Plug is built for that and Dosio does not claim to be.
