We've got the math!

Vial size, bacteriostatic water, your dose. That's it — you get the exact draw in syringe units, the concentration, and how many doses are left in the vial. No converting milligrams in your head at the kitchen counter, and no calculator built by someone who profits from the answer.

Then let the scheduling assistant remember the rest. Tell it what you're on and when, and it sends a reminder to your phone the moment each dose is due — every peptide, every schedule, one tap to log it. Free, and it works on iPhone and Android.
