Regimen vs Peptiq: AI Scanning vs Calculator Stack

Two Different Tools for Two Different Jobs

Peptiq and Regimen both serve peptide users, but they have meaningfully different designs. Peptiq is built around a calculator and reference stack: reconstitution calculator, unit converter, vial duration and cost calculator, and a 35-peptide database with full profiles. Regimen is built around a dose audit trail: AI care-plan scanning, an immutable ledger, and doctor-ready PDF output.

That difference is worth understanding before you choose.

What Peptiq Does Well

Peptiq advertises itself as "Your Complete Peptide Companion" and leans into education alongside tracking. Their peptide database covers 35+ compounds with dosing guidelines, mechanisms of action, and reference data. The reconstitution calculator handles BAC water math — how many units to draw for a target dose based on vial concentration. They also offer a unit converter (mcg, mg, IU), vial duration and cost calculator, and wellness tracking for mood, energy, sleep, and weight.

They support both iOS and Android, which matters if you're on a different platform than iPhone. Their premium tier includes a 7-day free trial (exact pricing not listed publicly on peptiq.io as of April 2026 — check their site for current numbers).

Peptiq also offers protocol templates and a stack optimizer, which can help first-time users who don't have a provider-issued care plan and need guidance building a protocol from scratch.

What Regimen Does Differently

Regimen assumes you already have a protocol — from a TRT clinic, a peptide prescriber, or a compounding pharmacy. The app is designed to execute that protocol faithfully and document it.

AI care-plan scanning. Regimen's scan-label feature uses AI to read a photo of a provider's printed protocol sheet. It extracts the compound name, dose, frequency, and cycle structure automatically. No competitor in this survey advertises anything comparable. If you receive protocols as PDFs or printed sheets, this saves meaningful setup time and reduces transcription errors.

Vial label scanning. A second scan mode reads individual vial labels — handles the lot code dictionaries for common compounding house codes like CJCIPA (CJC+Ipamorelin) and BPCTB (BPC+TB-500) — and creates a protocol from the vial alone. Useful when you have the vial but no separate care sheet.

Human body diagram for injection rotation. Regimen's injection site picker shows an anatomical front/back view of the body. You tap the exact muscle or subcutaneous site for each dose. The app tracks which sites were used and when, and surfaces them for each dose log. Peptiq advertises an injection site tracker, but based on their public listing, it appears to be table-based rather than a body diagram. The visual distinction matters for users who rotate through multiple sites on a complex multi-compound stack.

Vial supply tracking with reorder alerts. Log an open vial and the number of doses it holds. Regimen counts the supply down as you log doses, projects the run-out date by walking your dose schedule forward, and raises a Low Supply alert a configurable number of days ahead so you can reorder before you run dry. Peptiq's vial duration calculator estimates how long a vial lasts; Regimen tracks the live supply and pushes the alert.

Immutable dose ledger with soft-void undo. Every dose log in Regimen is append-only. If you log in error, you don't delete the record — you void it with a timestamp. The history view shows both the original log and the void event. This is the same design used in pharmaceutical dispensing systems. Peptiq does not mention an audit trail or soft-void capability on their public site.

PDF report sharing. Regimen generates your dose history as a formatted PDF designed for provider review. You can filter by date range and compound, then share the file directly from the app. This is the "doctor visit" flow. Peptiq does not advertise a PDF sharing feature.

Where Peptiq Has the Advantage

Peptiq still has the deeper calculator stack. Regimen ships a reconstitution calculator (the Built-In Dose Planner is on iOS inside the protocol setup screen and on the web at /calculators/dose-planner — same math, byte-for-byte verified), but unit conversion (mcg/mg/IU as a standalone tool) and a dedicated vial cost calculator remain on the backlog. Vial duration is no longer a gap — Regimen now tracks an open vial's remaining doses and projects its run-out date directly, with a reorder alert. If standalone conversion and cost estimation matter, Peptiq covers those today.

Peptiq also has deeper reference content. Their 35+ peptide database with full profiles — mechanisms, dosing guidelines, stacking recommendations — is more extensive than Regimen's compound catalog, though Regimen's catalog now ships subtitles, mechanisms, components, benefits, side effects, contraindications, sourced citations, and an outcome timeline per compound, narrowing that gap considerably.

Android support. Peptiq ships on Android. Regimen is iOS-only.

Where Regimen Caught Up: Outcomes + Reactions

The 1.17 release added two things that used to be Peptiq-only territory.

Tracked Outcomes & Rate Today. Score how you feel each day across the dimensions that compound is supposed to move — mood, energy, libido, sleep quality, focus, joint pain, appetite. Apple Health fills in the objective metrics: weight, body fat, sleep stages (REM, deep, light, awake), HRV, resting heart rate, glucose, BMI. Each outcome gets a 30-day sparkline next to your dose history, so the question "is this protocol actually working?" gets a chart instead of a guess.

Reactions Journal. Log side effects tagged from a curated library across GI, mood, energy, sleep, sexual, cognitive, and injection-site categories — plus user-defined custom tags. Optional 1–5 severity, free-text note, and 30-day backdating. Reactions appear in History with their own filter chip, and every protocol has a Reactions block on its detail screen with a 30-day sparkline.

Both ship in the iOS app today and feed into the PDF report's Outcomes Since Starting section so your provider sees them at the same time as the dose log.

Who Should Use Which

Choose Peptiq if: You want a unit converter and vial cost/duration tools in the same app as your tracker, you want their deep reference content for early-stage compound research, or you're on Android.

Choose Regimen if: You receive protocols from a provider as a printed care plan or PDF, you want AI to extract your protocol from a photo so you don't have to type it, you need an audit-grade ledger with soft-void that you can defend to a medical professional, you want subjective ratings paired with Apple Health biometrics on every protocol, you want a reactions journal for side effects, or you have a doctor who wants a formatted PDF of your dose history with outcomes attached.

The comparison table above shows every feature honestly — including where Regimen shows a gap. Neither app is universally better. They're built for different primary use cases.
