Reconstitution Calculator
Vial mg + BAC water mL → exact insulin-syringe units. Accounts for concentration target and needle size. Eliminating the Reddit-calculator step that causes order-of-magnitude errors.
One syringe-unit error is an overdose. Stop doing peptide math on Reddit.
vialfile reconstitutes your vial, logs your injection sites, tracks side effects, and tells you when your next lipid panel is due. Built by peptide users who got tired of the spreadsheets.
Supports BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, KPV, MOTS-C, and 20+ others.
How it works
-
1
Add your peptide and reconstitute safely
Pick from the library of 25 peptides — the calculator fills in canonical dosing ranges from public protocols. Enter your vial mg and BAC water volume; get exact insulin-syringe units with no math on your part. Dosing context, contraindications, and bloodwork cadence surface automatically.
-
2
Log every injection and side effect in seconds
Choose your injection site from the 7-site rotation map, confirm dose, and optionally note side effects by severity and symptom. Your injection history and effect patterns build automatically. The weekly digest shows dose counts, severity trends, and which peptides changed week-over-week.
-
3
Never miss a bloodwork draw again
Add a bloodwork protocol per peptide and vialfile tracks the cadence — lipid panel every 8 weeks for GH secretagogues, hematocrit for TRT-adjacent stacks. Status surfaces as on-track, upcoming, or overdue. Inventory tracks remaining mg and flags when a vial runs out before your next draw date.
Everything in one place
Injection Log & Site Rotation
Seven-site rotation map, per-dose timestamp, and protocol stack context. Prevents site overuse and dose-interval drift. The pattern view surfaces how your sites and timing have changed over weeks.
Side-Effect Tracker
Log severity, symptom, and onset for each effect. The pattern grid surfaces which peptides correlate with which symptoms across weeks. Severity trends and same-day injection counts help distinguish causation from coincidence.
Bloodwork Cadence & Inventory
Per-peptide bloodwork protocols with on-track / overdue status. Inventory tracks vials by FIFO burn-rate and warns when supply runs out before your next draw. The weekly digest rolls all four surfaces into a prescriber-ready summary.
The reconstitution calculator is live.
vial mg + BAC mL → insulin-syringe units — try it now, no login.

Questions
What peptides does it support at launch?
The common ~25: BPC-157, TB-500, GHK-Cu, Ipamorelin, CJC-1295 (with and without DAC), Sermorelin, Tesamorelin, KPV, MOTS-C, Epithalon, Semax, Selank, Thymosin-alpha-1, LL-37, AOD-9604, Melanotan II, PT-141, Retatrutide (research-only), and a few more. If yours isn't listed, you can still log a custom entry with manual dose math.
Is my data private?
Yes. All tracking data lives in your browser's localStorage — nothing is sent to our servers until you explicitly create an account (coming post-launch). No PHI is shared with advertisers, ever. The stack is built specifically without third-party analytics beacons. See our Privacy Policy.
Are you FDA-approved or a medical device?
No. vialfile is a tracking and math tool, like a spreadsheet with a calendar. We do not diagnose, prescribe, or dispense. Your clinician does that. Read our Terms of Service for the full scope of use.
When does it launch?
MVP targeted for 6 weeks from now. Waitlist members get first access. Follow the build on @bitinvestigator.
How does the pricing work?
The calculator and core log are free forever — no account required. Core ($14/mo) unlocks unlimited peptides, full history, and the bloodwork + inventory surfaces. Pro ($29/mo) adds PDF bloodwork parsing and multi-stack tracking. All plans are month-to-month at launch; annual pricing comes after we hit 100 paying subscribers.
