The thesis One app for the whole stack

Other apps log. Epti connects.

Sleep talks to training. Labs talk to your plate. Protocol talks to recovery. One missed dose, one rough night, one new lab — and every recommendation re-tunes.

Dedicated sport modes 10 built-in · more every cycle

Why Epti

The only app that knows your training scheduleandyour peptide protocol.

Same dashboard · same engine · same week. No more flipping between strava, notes.app, and a spreadsheet to figure out whether your tempo run lands on a BPC dose day.

Each mode rewires programming, recovery, metrics, and Coach E. Pick one. Or stack two.

How it works

From your first vial to your best lift in minutes.

Adaptive engine

A program that rewrites itself around you.

Epti's adaptive engine continuously analyzes your training logs, recovery, peptide phase, and bloodwork to reshape your program week-over-week — not just rep schemes, but volume, macro targets, and recovery prescriptions.

  • 01Auto-deload detection from HRV, sleep, and RPE trends
  • 02Macro targets that shift with your cycle phase (bulk / cut / cruise)
  • 0311-zone recovery model — knows when BPC-157 or TB-500 is in your stack and weights tendon & ligament loading accordingly
  • 04PR tracking with your protocol overlaid — every 1RM plotted against peptide cycles, sleep, and bodyweight
  • 05AI-generated programs: powerlifting, hybrid, basketball, cycling — plus templates for PPL, Upper/Lower, 5/3/1, GZCL
  • 06Drift detection: flags when your protocol isn't producing expected results

Compound library

Every peptide, researched before it's logged.

A live, editorial library of every compound in the community — reconstitution math, half-lives, side-effect profiles, vendor COAs, and the studies behind the claims. So your protocol starts on something more than a Reddit thread.

  • 01Editorial guides on reconstitution, injection technique, storage & reading COAs
  • 0269 compounds across weight loss, muscle growth, healing & recovery
  • 03Vendor index with community-verified COAs

Protocols

Every vial. Every dose. Every cycle. Tracked.

Add a vial in 30 seconds. Epti handles the reconstitution math, calculates units to draw per dose, tracks remaining volume, warns before you run out, and logs every injection with site rotation and reminders.

  • 01Visual syringe diagram showing exactly how many units to draw
  • 02Smart reminders with "DUE IN 15 MIN" status indicators
  • 03Auto site rotation map (subq + IM)
  • 04Cost-per-dose and cost-per-cycle tracking
  • 05Cycle library: active, past, and archived protocols in one editorial timeline

Coach E
ONLINE · KNOWS YOUR STACK
Is it safe to stack BPC-157 with my current cut?
Yes — with your protein at 182g and BPC dose of 250mcg, recovery markers look strong. Watch your CRP, which trended up 8% last cycle.
Why did my bench stall this week?
Three signals: sleep avg dropped to 5h 50m, you missed 2 BPC doses on Mon/Tue, and pressing volume was +18% vs last week. I'd deload bench Thursday.

Ask Coach E…
Coach E · AI

Peptide, training, and recovery questions — answered instantly, in context.

Coach E reads your protocol stack, training history, sleep, and bloodwork before it answers. It's not a generic chatbot — it's a coach that already knows what you ran last cycle.

"Is it safe to stack BPC-157 with my current cut?"
Yes — contextual answer referencing your protein 182g, 250mcg BPC, and last CRP +8%.
"Why did my bench stall this week?"
Sleep dropped to 5h 50m, you missed 2 doses, and pressing volume was +18%. Deload Thursday.
Community

Closed circles. Real signal.

Real days. Real notes.

Join private groups built around how you actually train — recomp, hybrid, sleep & recovery. Follow friends whose protocols match yours. Eight people in your circle, not eight hundred. Just the ones who get it.

Posts from athletes you follow — the days that went sideways and the ones that finally clicked. Filter by All, Following, or Tags. No engagement loops, no influencer slop.

Devon R.Hybrid · lean mass cycle
"I joined Recomp Lab and within a week three people had already swapped notes on the exact dosing schedule I was second-guessing. That's not a feed — that's a group chat with my labs in it."

Sasha M.Powerlifter · recomp
"My coach and I share a private group. He sees my doses, lifts, and labs in real time — no screenshots, no spreadsheets. It's changed how we program."
— Coaches with athletes
Riley T.Recomp · @rileyt
"My friends list is eight people, not eight hundred. I can see what they ate, how they slept, what they're cycling — and they can see mine. That's the whole point."
— 8 friends
Ava C.@avalifts · powerbuilding
"Posted 'squats moved like trash today but i hit them anyway.' Got four comments from people who'd been in the same place that week. That's the point — not pumps, not PRs. Just the showing-up."

Marcus D.Hybrid runner · zone-2 block
"Following four hybrid athletes on similar protocols changed how I think about pacing. The feed's not a leaderboard — it's people thinking out loud about their actual training week."
