— The problem

You're juggling a dozen compounds, three apps, a spreadsheet, and a calculator. Your supplements don't talk to your peptides. Nothing knows what cycle you're on. Every existing app logs what you already took — none of them help you plan what to take next.

— How Staxly works

Built around planning, not logging.

01

Goal in, protocol out.

Pick your goal — fat loss, muscle gain, recomp, first GLP-1 cycle, recovery. Staxly proposes a phased, multi-week protocol you can customize. The daily log falls out of the plan, not the other way around.

90 seconds from install to a 12-week plan
02

Pills, powders, peptides — one schedule.

Stop juggling three apps. Staxly handles supplements and peptides in a single timeline, with one inventory and one set of reminders. The tricky math for mixing peptide vials is built in — no separate calculator, no spreadsheet.

Tell it your vial, it figures out the syringe
03

Conflict-aware timing.

Zinc and magnesium fight for absorption. Vitamin D needs fat. GHRPs want an empty stomach. Staxly knows the rules, schedules around them, and flags it when you create a conflict yourself.

100+ compounds. Every known interaction.
— A day in Staxly

See your day, laid out clean.

Every dose, every injection, every powder — scheduled by what your body actually does with it. Not by what you can remember.

  • A
    Automatic timing Your zinc moves to evening so it doesn't block morning iron absorption.
  • B
    Cycle context "Week 4 of 12. Ramp-up phase. Next escalation Sunday."
  • C
    Inventory awareness "Your BPC vial runs out in 8 days. Reorder reminder set."

— Who it's for

Three people. One app.

— The Cutter

You're 8 weeks out from a vacation.

Creatine, whey, a multi, maybe a fat burner. Curious about peptides but haven't pulled the trigger. Staxly plans your cut today and onboards your first peptide tomorrow — no panic, no spreadsheet.

— The First-Timer

You just ordered your first vial.

Semaglutide for the cut, or BPC for that nagging shoulder. The reconstitution math is overwhelming, you don't know when to inject, and every Reddit post contradicts the last. Staxly gets you from "I ordered" to "I'm on week 4" without the spiral.

— The Stacker

You already run a serious protocol.

Multi-peptide cycles, ten-plus supplements, real periodization. Today: a spreadsheet, two apps, a calculator. Tomorrow: one app that warns you about timing conflicts you didn't even know existed.
