Goodtides Companion

Your whole protocol, in your pocket.

Companion does the syringe math, reminds you when to inject, tracks every vial, supply and cycle, reads your bloodwork, and reorders before you run out. The catalog you shop is the catalog you log — buy and track in one place.

Everything it does

One app for your whole protocol.

Smart reminders

A push before every scheduled dose, named by peptide. Pick your lead time; one you've already logged won't nag.

🧮

Dose calculator

Vial mg + BAC water become the exact units to draw, on a syringe you can drag. Injectable or oral.

🧬

43-compound catalog

43 peptides and blends, each with dose tiers, frequency, timing, route and cycle guidance built in.

🩸

Bloodwork tracking

Upload a lab PDF and it reads your markers, then tracks them against optimal ranges over time.

🗓️

Injection calendar

Every dose on a per-peptide month and year heatmap, today ringed, tinted by how you felt.

📈

How you feel

Rate each dose and tag effects. A 7-day trend shows how you're actually responding.

🔁

Site rotation

Suggests and records your spot, with a chart that nudges you to switch areas before one's overused.

🧪

Vials and supplies

Track multiple open vials with a draw-from switch; wipes, needles and BAC water count down as you go.

🌊

Never run out

Forecasts your empty date and reorders in a tap, only when you're actually low.

♻️

Cycle history

Finished vials roll into a per-peptide ledger that nudges your next cycle on time.

🧭

Guided setup

A welcome walkthrough, a guided tour, and a paced how-to-inject demo get you going on day one.

💧

Mixing guide

A reconstitution guide draws the exact BAC-water fill, so your first vial is mixed right.

Goodtides Companion — bloodwork tracking
New · Bloodwork

Your labs, read and tracked.

Drop in a lab PDF — LabCorp, Quest, Hone and Maximus are read automatically — and Companion grades your biomarkers against Goodtides optimal ranges, not just the lab's normal flag.

  • 103 markers across 10 panels: optimal · in range · out of range
  • Trends over time with optimal bands, plus per-marker sparklines
  • Protocol-aware — suggests markers to watch and peptides that may help
  • Private by design: your PDF is never stored, only the numbers you confirm

See the real screens.

What it is, and isn't

What it is: a tracker and a calculator. It records what you enter (protocols, doses, injections, vials, supplies, schedules) and does the arithmetic of turning vial mg and water mL into syringe units. Catalog dosages shown alongside peptides are commonly cited research figures, included as a reference.

What it isn't: a medical service. Goodtides does not provide medical care, evaluate your condition, or advise on individual dosing. Peptides are research compounds, not FDA-approved drugs. Decisions about whether and how you use them are your own. Consult a licensed provider before starting, adjusting, or combining any protocol.

Run your protocol like a pro.

Free, installs in a tap, and waiting for you. Open it on your phone and add it to your home screen.
