What it does
02
Log doses in one tap.
One tap from your home screen. PEP9 remembers the peptide, site, and time, and your last entry stays a thumb-stretch away.
03
Never miss a protocol.
One quiet push per dose, on your schedule. No streaks, no badges, no friend leaderboard. Just the right notification at the right time.
How the math works
- 1
5 mg ÷ 3 mL = 1.667 mg/mL
- 2
1.667 mg/mL × 1,000 = 1,667 mcg/mL
- 3
250 mcg ÷ 1,667 mcg/mL = 0.15 mL
- 4
0.15 mL × 100 units/mL = 15 units
Draw to 15 units. Every time.
Same inputs, same answer. The app shows every step so you can sanity-check it before you draw.
Why PEP9
Most people tracking peptides use the Notes app or a spreadsheet that's been Frankensteined into a tracker. It works, until it doesn't. A missed entry, a math error, a vial you forgot you opened.
PEP9 is the alternative for people who want their protocol to feel like the rest of their life: simple, quiet, and exact. Three things, done with care. No social feed. No coach in your pocket. No streak that guilt-trips you into self-medicating.
Built by one developer who needed a better tracker than a Notes file. Priced so you'll actually keep using it.

Questions
-
Is PEP9 medical advice?
No. PEP9 is a personal tracking tool. It logs what you enter, calculates math you give it inputs for, and reminds you on the schedule you set. It does not recommend peptides, doses, or protocols. Consult a licensed healthcare provider.
-
What peptides does PEP9 support?
Any peptide you choose to track. PEP9 doesn't maintain a list of endorsed substances. You enter the peptide name, dose, and schedule; the app logs what you tell it.
-
How does the reconstitution calculator work?
You enter vial size (mg), BAC water volume (mL), and target dose (mcg). PEP9 returns syringe units for a U-100 insulin syringe. The math is shown step by step.
-
Will PEP9 sync between my devices?
Yes. Logs and protocols sync via your iCloud or Google account so the same data appears on iPhone, iPad, and Android.
-
When does PEP9 launch?
PEP9 launches on iOS and Android in 2026.
