Terms of Use

Last updated 2026-09-20; in force since 2026-09-17. FreePeptideCalc and Peptide Calculator App (together, the “Services”) are operated by Kashif Khan, an individual in Pakistan, reachable at iamkashifcs@gmail.com. Using either Service means accepting what follows. If you do not accept it, do not use the Services.

What the Services are

Free calculators and reference pages about peptide reconstitution and dosing. Calculators perform arithmetic in your browser or on your mobile device. The app includes dose and reconstitution arithmetic, a U-100 unit converter, and a blend calculator for up to four vial components. The app can also save recent calculations locally on the device. The website’s reference pages reproduce figures from FDA labelling and published research, each one cited on Sources.

It is not medical advice, and no clinician has reviewed it. That is set out in full in the medical disclaimer, which forms part of these terms. Several compounds covered here are not approved for human use in any country, and the site publishes no dosing schedule for them.

Your side of it

• You are responsible for what you enter and for what you do with the result. A calculator cannot tell whether the number you typed is a sensible dose — it converts what it is given.
• You will not use the Services where doing so would be illegal where you are, and you will not present its output as medical advice to anyone else.
• You will not attempt to disrupt the Services, scrape them in a way that degrades them for others, or pass its content off as your own.
• You are of legal age in your jurisdiction. The site is not intended for children.

No warranty

The Services are provided as is, with no warranty of any kind — express or implied — including any implied warranty of merchantability, fitness for a particular purpose or non-infringement. Specifically, and despite real effort to the contrary:

• The arithmetic is tested, but no software is free of defects. Check any figure that matters before acting on it.
• Source documents change. A label is revised, a study is retracted, a regulatory status moves. Pages carry the date they were last verified; nothing here is warranted to be current at the moment you read it.
• Availability is not guaranteed. Either Service may be changed, taken down or discontinued at any time without notice.

Limitation of liability

To the fullest extent permitted by law, Kashif Khan is not liable for any loss, injury or damage — direct, indirect, incidental, consequential or otherwise — arising from your use of the Services or from reliance on anything published or calculated through them, including any decision about a substance, a dose or a medical course of action.

Nothing in these terms excludes liability that cannot lawfully be excluded, such as liability for death or personal injury caused by negligence where your law does not permit its exclusion. Where a limitation is held unenforceable, it applies to the maximum extent that is enforceable and the rest of these terms stand.

Content and reuse

The text, page structure and code of this site belong to Kashif Khan. The primary documents it cites do not — FDA labelling is a United States government publication, and published studies belong to their authors and publishers. Those are quoted and linked, not claimed.

You may quote from these pages with attribution and a link. You may print the dosing charts and use them. You may not republish the site wholesale or present its content as your own work. The name and mark FreePeptideCalc are not licensed for reuse.

Analytics and review prompts

The mobile app may send limited anonymous product-interaction events to Aptabase only when configured and after you enable them. Calculator entries, component names, dose amounts, and results are excluded. You can disable future events in the app’s Settings screen. Full details are in the privacy policy.

After meaningful use, the app may ask Apple or Google to show their native review prompt. Responding is optional, is not rewarded, and does not change access to any feature. The store controls whether the prompt appears and processes any rating under its own terms.

App stores and updates

If you obtain the app through Apple App Store or Google Play, that store’s terms also apply. The store is not responsible for the calculator’s content. You are responsible for installing updates; an older build may not contain the latest fixes or notices.

Links out

Pages link to regulators, journals, manufacturers and, on the comparison pages, to other calculators. Those sites are not under our control and their content is their own responsibility. A link is not an endorsement.

Advertising

The website currently carries no advertising, and the mobile app contains no advertising SDK. If website advertising is added, it will be labelled as such, will not be dressed up as editorial content, and the privacy policy will be updated to name the network before any of its tags load.

Changes

These terms may be revised. The version on this page is the one in force, and material changes will be reflected in the date at the top. Continuing to use the Services after a change is acceptance of it.

Governing law

These terms are governed by the laws of Pakistan, and the courts of Pakistan have jurisdiction over any dispute arising from them. If you use the Services from somewhere with consumer protections that cannot be contracted away, those protections still apply to you — this clause does not remove them.
