Peptide education · Self-tracking

Peptides, matched to your goals and tracked against how you actually feel.

PepLoop scans your face or body, surfaces peptides that may be relevant, and logs every dose, so patterns surface over time.

Informational, not medical advice.

How it works

Three steps, one loop.

Scan, see what may fit, then track how you feel. The loop closes when your own data starts answering back.

Scan

Scan your face or body

A quick photo, analyzed on the spot. The image stays on your device; only the text result is saved, and our servers never keep the photo.

Get suggestions

See what may be relevant

An AI companion surfaces peptides that may fit your goals, demographics, and history. Educational context, never a prescription.

Track & see patterns

Track how you feel

Log doses, rate how you feel, and watch patterns emerge across cycles, so you can see what is actually working for you.

Meet the four

The guides you travel with.

Four companions, each with a job and a color. They are the whole personality of PepLoop, and the only color on this page.

Loop, the blue infinity-shaped guide mascot.
Loop · the guide

Loop shows you the way in.

Your guide through scanning and home base. Loop sets the rhythm of the loop and keeps the first step simple.

Pep, the coral-red mascot flexing, for tracking and streaks.
Pep · tracking & streaks

Pep keeps you in rhythm.

Doses logged, check-ins kept, streaks intact. Pep turns the daily habit into something you can actually see building.

Nodi, the green mascot with molecular nodes, for the peptide library.
Nodi · peptide library

Nodi holds the knowledge.

The library, in person. Nodi keeps what each peptide is and what it may do, so a suggestion always comes with the context behind it.

Shade, the dark mascot with teal accents, peeking over a chart with a magnifier, for insights.
Shade · insights & premium

Shade reads the patterns.

The quiet analyst. Shade looks across everything you have logged and surfaces the patterns worth noticing.

Where we stand

Calm, clear, and on your side.

Not a clinician

Informational, by design.

PepLoop is educational. It does not diagnose, prescribe, or replace your doctor. Always consult a licensed clinician before changing any therapy.

Your data, yours

You stay in control.

Scan photos are analyzed and discarded on our servers; results stay on your device. Delete your account and data anytime, for good.
