Founding Member Lifetime Spots · iOS & Android Launch Coming

One shot a week. More going on in your body than you think.

The app your prescription
should have come with.

Most people on GLP-1s think there's nothing to track. Then week 6 hits — the motivation crash, the emotional flatness, the Wednesday nausea that isn't random. Peptide Companion explains what's happening in your body. Not just logs it.

What's inside

Built for the medication.
Not adapted for it.

Every feature exists because someone on GLP-1 or peptide therapy actually needed it — not because a product manager added it to a roadmap.

📊
The Journey Chart — Our Signature Feature
The most advanced weight-loss chart available. Your line colour-codes by dose — see exactly when escalation accelerated results. AI annotations surface your best week, plateau breaks, and dose milestones directly on the chart. Photo thumbnails on the timeline. Interactive tap-to-reveal data points. Animated draw on load. Nothing like this exists anywhere else.
Signature feature · Not available elsewhere
Personal Intelligence
Claude AI reads 28 days of your real data and writes an insight that references your actual patterns — your streak, your nausea curve, your protein consistency. Not a template. Updated daily.
🌡️
14-Day Symptom Timeline
14 columns × 6 symptom rows, colour-coded green through red. Tap any cell for that day's full context. See every pattern at once.

The question we get asked

"It's just one shot a week.
What is there to track?"

We see this comment everywhere. It's the question of someone who hasn't hit week 6 yet.

🧠
The week 6 motivation crash
GLP-1s modulate dopamine pathways. The same mechanism that quiets food noise also affects motivation broadly. It's documented, it's temporary, and it has a name: dopamine recalibration.
📅
Your mid-week nausea isn't random
Peak medication concentration hits 36-48 hours post-injection. That means your worst days are mathematically predictable — and completely plannable once you know the pattern.
💙
The food grief nobody warns you about
When food noise goes quiet, something you've relied on for decades disappears overnight. That can feel like grief. It has a neurological explanation, and it's more common than you think.
📊
The plateau that isn't failure
The scale stops moving. You think the medication stopped working. It didn't — body recomposition is happening invisibly. Fat down, muscle up. The scale just can't see it.
🪞
The identity shift nobody mentions
Losing weight faster than your self-image can update. The mirror changes before your brain catches up. You can lose 20 lbs and still flinch expecting to see the old reflection.
🍽️
The social friction at every dinner
Food is social. When you stop eating the way people expect, relationships get complicated. Your family notices. Your friends comment. Nobody prepares you for navigating this.

That's what there is to track. Peptide Companion is the app that understands all of it — because it was built by someone who lived it.

Our story
I've been on GLP-1 medications for months. I tried every tracking app and none of them understood what I actually needed — the nausea timing, the injection rotation, the food noise, the peptide support. So I built one. Not as a developer. As a user who got frustrated enough to figure it out.

Common questions

Everything you need to know.

What is Peptide Companion?

Peptide Companion is a GLP-1 and peptide companion app for iOS and Android. It's not a tracker — it's the app your prescription should have come with. It supports the full spectrum of GLP-1 medications (Ozempic, Wegovy, Zepbound, Mounjaro) and peptides (Retatrutide, BPC-157, CJC-1295, TB-500, Ipamorelin) with AI-powered pattern detection, a 14-day symptom heatmap, injection site rotation, and more.

Is Peptide Companion available on Android?

Yes. Peptide Companion launches on iOS and Android simultaneously. Unlike most GLP-1 apps that start iOS-only, Android was built natively from day one.

Does Peptide Companion support Retatrutide?

Yes — Retatrutide is a first-class supported medication in Peptide Companion, not an afterthought. The app understands Retatrutide's triple agonist mechanism, its longer half-life, and its distinct side effect profile. It's the only GLP-1 app built specifically for Retatrutide users.

Can I track BPC-157, CJC-1295, and other peptides alongside my GLP-1?

Yes. Peptide Companion supports full peptide stacks — BPC-157, TB-500, CJC-1295, Ipamorelin, Sermorelin, Tesamorelin and more alongside any GLP-1 medication. Each compound has its own injection schedule, PK curve, and site rotation tracking. No other GLP-1 app handles this.

What is the Personal Intelligence AI and how does it work?

The Personal Intelligence AI analyses your logged data — check-ins, symptoms, weight, injection timing — and surfaces patterns specific to you. Not generic tips. Your patterns. After 7 days of logging it starts detecting trends. After 14 days it connects dots. It's powered by Claude AI and references your actual journey, not a template.

What is the Perimenopause Overlay?

The perimenopause overlay lets you track your hormonal cycle alongside your medication data. Oestrogen and progesterone fluctuations interact directly with GLP-1 effectiveness, side effect intensity, and weight patterns. Peptide Companion is the only GLP-1 app that acknowledges and tracks this.

How is Peptide Companion different from Shotsy or MeAgain?

Shotsy is a shot logger. MeAgain is a beautiful daily dashboard for standard GLP-1 users. Peptide Companion is a companion — it understands your protocol, detects your patterns, supports your full peptide stack, goes deep on the psychological side of GLP-1 therapy, and is built for the full spectrum of medications including Retatrutide. It's a different category of product.

What is the Founding Member offer?

The Founding Member offer is a one-time lifetime subscription at a significantly lower price than the regular annual plan. It's available for early members only — when we close it, it closes permanently. The price is revealed at checkout. No subscription, no renewals, every feature included forever.

Is Peptide Companion a medical device?

No. Peptide Companion is not a medical device and does not provide medical advice. It is an informational and tracking companion. Always consult your prescriber before making changes to your medication or protocol.
