RECONSTITUTION CALCULATOR — MATH-FREE Simply enter your vial size and desired dose. The calculator solves the optimal amount of BAC water and gives you the exact syringe draw. Supports mg, mcg, IU, and all standard insulin syringe formats. No more guessing your reconstitution math. DAILY DOSE TRACKER & INJECTION LOG Log every injection by time of day — waking, morning, evening, bedtime. Mark doses complete with one tap. See your full dosing history and protocol at a glance. Never miss a dose again. PROTOCOL MANAGEMENT & PEPTIDE STACK BUILDER Build custom protocols for any compound. Set frequency, duration, and dosing schedule. Track multiple peptides simultaneously and manage your full peptide stack without confusion. VIAL INVENTORY Know exactly how many doses remain in each vial. Track reconstitution dates, keep multiple vials per compound, and switch to a fresh vial without losing count. Never waste a vial again. WORKS WITH EVERY PEPTIDE & GLP-1 COMPOUND Whether you're managing a GLP-1 protocol, peptide cocktails like GLOW or KLOW, or a full biohacker peptide stack, compound-aware support is built in. BUILT FOR THE PEPTIDE COMMUNITY PeptideFox understands the real-life scenarios of compound reconstitution, injection tracking, and managing multiple vials and supply — the calculator, tracker, and inventory all work from the same data, so nothing needs entering twice.
