How does the reconstitution calculator work?

Enter how much peptide is in the vial, how much bacteriostatic water you added, and the dose you want. Vialo returns the exact draw in U-100 syringe units, the resulting concentration, and how many doses the vial holds. Use the same unit throughout: vial and dose both in mg, or both in mcg. It is arithmetic, not advice — check the result against your provider's instructions.

Does my data leave my device?

No. Vialo has no account and no server. Everything stays in the app's private storage on your device. If you enable Apple Health, weight is exchanged with Health on your device only.

What do I get with Pro?

Unlimited compounds and stacks, automatic titration plans, the weight trend with dose-increase markers, side-effect tracking over time, and Apple Health sync. The free tier keeps one compound, dose logging, the reconstitution calculator and weight logging.
