50+ peptidesReconstitution mathAI guidance

The world's trusted peptide health layer.

REGEN tracks every vial, every dose, every biomarker — and gives you an AI second opinion before you draw. Built for the people who run their own protocols.

Today's protocol timeline
What's inside

Five tools that replace
a binder full of spreadsheets.

Every screen pulls from the same protocol. Change a dose in one place, the schedule, inventory, and biomarker baselines update everywhere.

01 / SCHEDULE

Your day, dosed. Down to the minute.

A timeline that knows the difference between fasted GH and post-meal berberine. REGEN sequences your day around the molecules — not a generic checklist.

01
Time-of-day windows
02
Pre-meal & fasted cues
03
Cycle-aware reminders
Your day, dosed.
02 / INVENTORY

Every vial, accounted for.

Track reconstituted vs lyophilized, mg remaining, expiry. Scan a new vial and REGEN does the BAC water math, the IU conversion, the units-per-click — silently, correctly.

01
Reconstitution calculator
02
Expiry & potency alerts
03
Stack-level inventory
Every vial, accounted for.
03 / REGEN AI

A second opinion, before you draw.

Ask REGEN AI about interactions, half-lives, blood panels, photo marks. Trained on peer-reviewed literature — never on forum threads pretending to be science.

04 / BIOMARKERS

Numbers in, trends out.

Log free testosterone, lipid panels, glucose, sleep — REGEN charts the trend against your protocol, flags drift, and tells you when it's time to retest.

01
30+ biomarkers tracked

05 / NUTRITION

Macros without the spreadsheet.

Snap a plate. REGEN breaks down calories, protein, carbs, fat — and ties it to the dose window it fell in. Because GLP-1 outcomes start at the table.

Photo macro scan
02
Window-aware logging
03

Loved by the people who
read their own bloodwork.

Finally an app that knows what 'reconstituted at 2mL' means without me explaining peptides to it. The dose calc alone is worth the install.

I've moved every one of my clients onto REGEN. The biomarker trend view is the cleanest I've seen — clearer than my EMR.

Switched from a Google Sheet I'd been maintaining for 14 months. Migrated in one evening. The AI flagged two interactions I'd missed.

The meal scan is the secret weapon. I stopped guessing protein and my titration finally smoothed out.

Reconstitution math used to make me anxious. REGEN turned it into a two-tap thing. Anxiety gone.

Inventory + expiry alerts saved me from injecting an expired BPC vial last week. Worth every penny just for that.

I run 30+ clients. The shared protocol view in REGEN replaced my entire ops stack. Notion, Sheets, all gone.

The timeline is the calmest dosing UI I've ever used. No red badges screaming at me. Just 'this is what's next.'

REGEN AI quoted me a half-life paper from 2019, with citation. I checked. It was real. That sold me.

The biomarker module references my labs against age-adjusted ranges. Not population averages. Huge for my practice.

Answers, before
you have to ask.

“Anyone running peptides is already past the point where vague answers help. So we don't give them.” — REGEN team

Is REGEN giving medical advice?
No. REGEN is a tracking and reference tool for adults who have already decided to run a protocol. Every dose calculation cites its source. We do not prescribe, diagnose, or recommend — you and your clinician do that.
Which peptides are supported?
50+ at launch, including Retatrutide, Tirzepatide, Semaglutide, BPC-157, TB-500, CJC-1295 (with and without DAC), Ipamorelin, IGF-1 LR3, MOTS-c, Epitalon, and the full GHRP family. We add new ones every release.
How does REGEN AI work?
It's a fine-tuned model trained exclusively on peer-reviewed literature, clinical trial data, and pharmacokinetic studies. It will not answer from forum posts or anecdotes. Every response is cited and traceable to the source paper.
Is my data private?
Yes. End-to-end encrypted, stored only on your device by default. Opt-in cloud sync uses zero-knowledge encryption — we can't read your protocols even if we wanted to. We never sell data and we never will.
Does the reconstitution calculator handle multi-peptide blends?
Yes. Input the mg of each peptide, the BAC water volume, and the syringe size — REGEN returns units-per-click for every component, and warns on solubility conflicts.
Can I share my protocol with a coach or clinician?
Yes. Generate a read-only link that includes your active stack, dose schedule, recent biomarkers, and notes. Revoke access at any time. Coaches on REGEN Pro can manage multiple shared protocols from one dashboard.
How much does it cost?
Free for the basic tracker. REGEN Pro ($14/mo or $120/yr) unlocks the AI, biomarker trends, photo meal scan, and unlimited shared protocols. Coaches get team pricing.
Can I import from a spreadsheet?
Yes. Drop in a CSV with dose, peptide, date and REGEN reconstructs your history, fills in gaps with reasonable defaults, and asks you to confirm. Most people migrate in under 20 minutes.
