Frequently asked questions
Is the peptide reconstitution calculator free?
Yes. The calculator is completely free and requires no account. Just pick a peptide, enter your vial mg and BAC water volume, and get your mg/ml concentration and syringe units instantly.
How does peptide reconstitution work?
Reconstitution mixes lyophilized peptide powder with bacteriostatic water to create an injectable solution. The concentration (mg/ml) depends on the vial's total mg and how much BAC water you add. ReconDose calculates this for you and converts your target dose into exact syringe units.
Which peptides does ReconDose support?
The calculator supports 25+ peptides including tirzepatide, semaglutide, retatrutide, BPC-157, TB-500, CJC-1295, ipamorelin, GHK-Cu, NAD+, MOTS-c, and more. You can also enter custom values for any peptide not in the catalog.
Can I track my dosing schedule and injections?
Yes. With a free account you can save protocols, generate dosing schedules, log every injection, and track side effects. Pro and Community plans add biomarker tracking, TRT protocols, food and exercise logs, AI insights, and more.
Is my data private?
Your data is stored in your own private database with per-user authentication. Photos and health data are never shared unless you explicitly choose to share them. You can export everything to CSV at any time.
Does ReconDose work on mobile?
Yes. ReconDose is a progressive web app (PWA) that works on any device. You can install it on your iPhone or Android home screen for a native app experience, including offline access.
