PepKeep: the peptide tracker that handles every dose and every vial
PepKeep reminds you at every dose with the exact units to draw, counts your vials down, and tells you when to reorder. It also shows the real cost of every shot. Works on iPhone, Android and desktop. 7 days free with everything unlocked, no card needed.
How it works
- Add your stack. Scan a vial label or pick from 86+ peptides. Enter the water you added once.
- Get reminded. Every dose arrives with the exact units to draw on a U-100 insulin syringe. Log it in one tap.

Frequently asked questions
Is PepKeep free?
Every new account gets 7 days free with everything unlocked, and no card is needed to start. After that it's $4.99 a month or $39.99 a year. If you skip a plan, everything you logged stays saved and viewable.
Does it work on iPhone and Android?
Yes. PepKeep runs in your phone's browser and installs to your home screen like an app, with dose reminders. It works on a computer too, and your stack stays in sync between them.
How does the units math work?
Tell PepKeep the vial size, how much water you added, and your dose. It shows exactly where to draw on a U-100 insulin syringe, and keeps track when your dose changes.
Do I have to buy from a certain vendor?
No. Track peptides from any vendor, and PepKeep tells you when to order so you never run out.
Is my information private?
Your stack is visible only to you. There are no passwords to leak; you sign in with a one-time email code. Your conversations with PepKeepR, by Siri or in the app, are saved for up to 90 days so we can make her better. They're never sold, only the service providers that run PepKeepR can process them, and email addresses and sign-in codes are never saved. You can delete your account and data from Settings at any time.
Does PepKeep tell me what to take?
No. PepKeep is a tracker and calculator. Use the protocol you and your clinician have chosen; PepKeep keeps it on schedule.
