Terms of service

Version 2026-09-03 · effective 3 September 2026

The short version: PepStepper is a calculator and a logbook. It does arithmetic on numbers you supply, it never tells you what to take, and it accepts no responsibility for any dose or for anything you do with a compound.

What PepStepper is

Software for tracking supplies, schedules and measurements you enter yourself, and for doing arithmetic on them.

It is not a medical device. It does not diagnose, treat, cure or prevent anything. It is not a substitute for advice from a clinician, and it is not pharmacy or medical services.

It never chooses a dose

Every number PepStepper displays is derived from a number you entered. It does not originate doses, recommend protocols, or suggest that you increase or decrease anything.

Where an approved product has a published escalation schedule, PepStepper may show that schedule as a quotation with its source printed alongside. That is a public regulatory document being reproduced for your reference. It is not a recommendation, it is not filled in for you, and the product you have is very likely not the product that label describes.

You are responsible for what you do. Check the arithmetic against the vial and the barrel in your hands before you act on it.

We accept no responsibility for any dose

This is the most important paragraph on this page. Read it before you use the calculator.

Every figure PepStepper shows you — a concentration, a volume, a number of units, a mark on a barrel, a doses-remaining count, a discard date — is arithmetic performed on numbers YOU entered, about a vial WE have never seen. We do not verify what is in your vial, what strength it is, what the label says, whether the label is true, what syringe you are holding, or whether any of it is what you believe it to be.

To the fullest extent permitted by law, PepStepper and BossDevs accept no responsibility and no liability of any kind for any dose, calculation, measurement, schedule, reminder, conversion or figure produced by or displayed in this software, or for any decision, act, omission, injury, loss or harm arising from it. That applies whether the figure was right, wrong, mistyped, misread, misunderstood, or produced by a defect in the software itself.

The responsibility for what enters your body is yours alone, and it is not transferable to a calculator. Check every number against the vial and the barrel in your hands before you act on it. If the arithmetic here disagrees with the physical object, the physical object is right.

Research compounds, not for human use

The compounds named in this software are research chemicals. The majority are not approved by the FDA or by any comparable regulator for human use, are not sold for human consumption, and are supplied by vendors for laboratory and research purposes only. Several are approved as medicines only in a specific product, at a specific strength, from a specific manufacturer, which is very unlikely to be the vial you are holding.

PepStepper takes no position on what you should do with any of them. A compound appearing in our catalogue is a reference label so that arithmetic can be performed and a log can be kept. It is not an endorsement, not a claim that the compound is safe, effective, legal or fit for any purpose, and not a suggestion that it should be taken by a person.

Nothing in this software should be read as encouraging, instructing or facilitating the human consumption or administration of any compound. What you choose to do is your decision, made on your own responsibility, and is subject to the laws where you are.

What we do not sell

PepStepper does not sell, supply, source or broker any compound, and contains no links to anywhere that does. It is software, and only software.

Your account

You must be 18 or older. One account per person. Keep your password to yourself — anyone with it can read your entire log.

Do not use a temporary or disposable email address. Reminders are most of what the product does, and they need somewhere real to arrive.

Subscription and billing

Plans are billed through Stripe. A trial requires a card up front and converts automatically unless you cancel before it ends.

Cancel any time from billing. Cancelling stops the next charge; it does not refund the current period. Your log stays yours and exports either way.

Founding-member seats are a one-time payment, capped at 100 and honoured as such. Lifetime means for as long as PepStepper operates.

Referrals

You earn credit when someone you referred makes their first real payment — not when they sign up, and not during a trial.

Referring yourself does not work. A second account of your own, an alias of your address, or your own card on both sides all resolve to the same person and the referral is void.

If a referred payment is later refunded or disputed, the credit is reversed. Both entries stay on your ledger.

Availability and liability

PepStepper is provided as it is. We do not warrant that it will be uninterrupted or error-free, and you should not rely on it as the only record of anything that matters to you.

To the maximum extent the law allows, our total liability to you is limited to what you have paid us in the twelve months before the claim.

Nothing here limits liability for anything that cannot lawfully be limited.

Ending it

You can delete your account at any time from settings. We may suspend or close an account that abuses the service, attacks it, or uses it to break the law — and if we do, you keep the right to export your data.
