A protocol run from memory, on sticky notes or a shaky spreadsheet, is where money and data leak. Peptide Lab replaces each doubt with one tap.
Peptide, mg, water: the app calculates the exact units to draw on the syringe. No mental math, no wasted vial.
Tap the site on the body map. The app tracks rotation across 14 zones and what is left in the vial.
Weight, effects, timeline: your whole cycle in one view. You adjust with data, not gut feeling.
Free, no card, ready in 30 seconds.
Five tabs, all available for free. Pro adds unlimited peptides, half-life curves, push notifications, custom blends, every lesson, cloud photos and CSV export.
Enter the mg, the water and your target dose: Peptide Lab gives you the exact volume and the units on the syringe. No mental math, no wasted vial.

Your vials: doses left, expiry, batch, and a real rhythm: every day, every N days or fixed weekdays.
Today's doses, calendar, 14-site body map, weight, journal, side effects, progress photos and email reminders at the time you choose.
Reconstitution, cycle, cost and blends (Klow, Glow, BPC+TB, CJC+Ipa): units on the syringe, vials to buy, price per dose, end date.
25 peptide sheets as short lessons with progress, trending sheets, and the 10-chapter reconstitution course.
Restock in one tap: best offer for your delivery zone, lab-tested vendors, supplies.
Pro adds: unlimited peptides, half-life curves and statistics, push notifications (Android, iOS coming), custom blends of 2 or 3 vials in one syringe, every lesson of every sheet, progress photos in the cloud with before / after comparison, full trends and CSV export of your whole history.

Encrypted in transit, visible to you alone, never sold or shared. The same data on the web and on Android with your email. Permanent deletion in one tap from the settings.
The app converts what you enter into syringe units and tracks your protocol. It never recommends a dose: these are your numbers, not ours.
