Three questions first. Then the rest.

No. 44 Protocol is a reference register only. We do not manufacture, sell, source, ship, prescribe, dispense, or recommend the purchase of any compound. We are not a pharmacy and not affiliated with any compounding pharmacy or peptide vendor. We publish the math and the citations — nothing else.

No. 44 Protocol is a research-literature reference. It does not establish a clinician-patient relationship and does not replace medical judgement. Every reference dossier must be reviewed with a licensed physician before initiation.

Email support@44protocol.com from your account address within 7 days and we refund the full charge through Stripe — typically same business day. No clock, no feature gating, no surprise charge. You get the entire register from minute one.

44 Protocol is a literature-derived peptide dosing register. It catalogs 57 research peptides across 6 therapeutic classes with bodyweight-scaled dosing, vial reconstitution math, U-100 syringe units, titration engines for GLP-1 class compounds, and primary-literature citations on every entry. It is built for physician-supervised practice.

Licensed clinicians who want a reproducible reference, informed patients who want to bring an organised literature dossier to their prescribing physician, and researchers who want a single place to track stack-level monitoring and labs. It is not for self-treatment without medical supervision.

Take the stack quiz. Sixteen questions across safety, goals, phenotype, logistics, and risk posture — we hard-screen for contraindications and match you to one of 29 research-backed protocols ranked by fit and confidence. No signup required to see your result. If you create an account afterward, the matched stack is loaded into your register automatically. You can override anything before you print.

A spreadsheet does not cite its sources, does not run a 7,000-assertion fuzz harness on every build, does not titrate GLP-1 ladders week by week, does not cross-reference your labs against the monitoring list of every compound in your stack, and does not reprint correctly on a PDF for your physician. 44 Protocol does all of that, and updates weekly against published literature.

Where published per-kilogram trial data exists, doses scale by bodyweight. Where only a fixed clinical dose has been published, we show the catalog default and label it as such. Every entry cites its primary source — PubMed ID, ClinicalTrials.gov NCT number, PMC link, or a named clinical protocol.

Each compound is graded by the highest-quality evidence available: FDA-approved, Phase 3 trial, Phase 2 trial, pre-clinical, or research use only (RUO). The grade is shown on every catalog entry. Read the methodology for grading criteria.

Semaglutide, tirzepatide, and retatrutide each have published titration ladders from their respective trials (STEP, SURMOUNT, TRIUMPH). The register encodes those ladders as week-by-week step functions with dose holds and step-downs for tolerability events. Other compounds use catalog defaults.

For compounds with a published per-kg dose, the register multiplies by your stored weight in kilograms. For compounds without a per-kg figure, it shows the catalog default and labels the field "catalog default" rather than silently inventing a scaled value.

The math is deterministic. Given vial mg and BAC water mL, it computes mg/mL and the volume per dose, then converts to U-100 syringe units rounded to the half-unit. The PDF and the on-screen display always show the same values. A fuzz harness runs 7,000+ assertions on every build to verify catalog parity, random stacks, and the three titration engines.

If a user identifies as peptide-naive, the register surfaces a medical-voice notice recommending the first week at half the catalog dose, then titrating up. The banner persists in the app and prints on every PDF export until the user is no longer marked naive.

A scheduled checklist surfaces every monitoring item (labs, vitals, symptom watch) and every serious adverse event across the user's current stack. The reminder triggers seven days after the last review. The user must sign off on every item to clear the banner.

When the user adds a lab result (manually or via CSV import), the register matches the marker text against the monitoring list of every compound in their stack. If there's a substring match, that peptide is flagged next to the result so the user knows which compound to watch.

Two reasons. First, the register costs us real money to maintain — weekly literature reviews, citation verification, and engineering effort — and trial gating attracts a meaningfully different audience than paid users. Second, our 7-day money-back guarantee is a stronger commitment than a trial: you get the full register from minute one, and we refund in full if it isn’t for you. No clock, no feature gating, no surprise charge at day eight.

Subscribe to either plan. If within 7 days you decide the register isn’t for you, email support@44protocol.com from your account address requesting a refund. We process it through Stripe — typically same business day — and you keep nothing recurring. The guarantee is available once per customer on the first paid subscription period only; renewals are non-refundable.

Open the app, go to Account, click "Manage subscription," cancel via the Stripe customer portal. Access continues to the end of the paid period.

In limited cases, yes. If the service is materially broken on our side within the first 14 days, we refund the most recent charge. Read the refund policy for full detail.

Stripe. 44 Protocol never sees or stores your card details. Payment goes to Stoneveil Holdings LLC, an Arizona registered company.

Account email, encrypted password, optional display name, weight, sex, your saved stack and reference-dossier settings, lab values you choose to enter, and behavioural analytics (page views, feature usage) for product improvement. We do not collect or store payment card details — Stripe handles those. Read the privacy policy for the full list.

Auth and application data are stored in Supabase (Postgres). Hosting is on Vercel. Both are US-region. Connections are TLS-only. Database rows are protected by row-level security so users can only read or write their own data.

Yes. Email support@44protocol.com from the account address. We remove your row from auth, your profile, your stack settings, your labs, and your stack history within 7 days.

44 Protocol publishes research-literature reference material only. We do not manufacture, sell, source, ship, prescribe, dispense, or recommend the purchase of any compound. We are not a pharmacy and not affiliated with any compounding pharmacy or peptide vendor. Whether a particular peptide is legal to obtain, possess, or use in your jurisdiction is your responsibility to determine with your licensed physician and applicable law.

Some are (semaglutide, tirzepatide, tesamorelin, PT-141 / bremelanotide, others). Most are not — the catalog explicitly grades each compound's regulatory status. "Research use only" entries are labelled as such.

Not formally, yet. If you are a clinic or research group with a use case, tell us about it.
