Peptily keeps your protocol straight: how much to draw, when the next dose is due, which site to use, and how much is left in the vial.
RECONSTITUTION MATH, DONE FOR YOU
Enter the powder, the water you added and your target dose. Peptily gives you the exact number to draw on a U-100 or U-40 syringe, in mL if you prefer, and tells you how many doses the vial holds. Free, forever.
NEVER MISS A DOSE
A reminder on dose day, not a stream of notifications. Your next dose also lives on the Lock Screen and in the Dynamic Island as it gets close, plus a Home Screen widget.
DOSE ESCALATION ON YOUR DATES
0.25 to 0.5 to 1.0 mg. Set the ladder once and every reminder follows it, so you stop counting weeks in your head.
SITE ROTATION YOU CAN SEE
Eight sites, color-coded by how recently each was used, with the next one suggested for you. Hitting rested tissue is the whole point.
THE VIAL, HONESTLY
A 10 mg vial at 0.25 mg a week holds forty doses, but the reconstituted solution only keeps about 28 days refrigerated. Peptily shows you which limit actually applies, and warns you before either one bites.
BUILT FOR STACKS
Running three compounds from one vial? Log it as a single shot instead of three separate entries.
YOURS, ON YOUR DEVICE
No account. No sign-up. No server. Your protocol never leaves your phone. Export a clean PDF when you want to show your clinician.
HOW IT WORKS
Peptily is fully open for your first 21 days — every feature, nothing withheld. After that, Pro keeps the log going, along with the dose escalation ladder, unlimited compounds and stacks, the site rotation map, your full history with a weight trend, and PDF export. Whatever you have already logged stays readable for free, always.
Peptily is a logging tool. It does not give medical advice, dosing recommendations or treatment plans, and it does not sell or source anything. Talk to a clinician about your protocol.
