The code

Paste this where you want the calculator to appear:

<script src="https://peptide-calculator.com/embed.js"></script>

For a compound-specific version, add data-calc with the page name:

<script src="https://peptide-calculator.com/embed.js" data-calc="bpc-157-dosage-calculator"></script>

Available values: reconstitution-calculator, bpc-157-dosage-calculator, bpc-157-tb-500-blend-calculator, tirzepatide-reconstitution-calculator, retatrutide-reconstitution-calculator, semaglutide-reconstitution-calculator, sermorelin-reconstitution-calculator, cjc-1295-ipamorelin-calculator, nad-reconstitution-calculator, peptide-calculator-mg, peptide-blend-calculator. Leave it off for the general calculator.

Where it works

WordPress (Custom HTML block), Shopify (Custom Liquid or an HTML section), Squarespace (Code block), Substack (not in posts; link instead), Ghost (HTML card), Webflow (Embed element), and any plain HTML page. Sites that strip script tags can use the iframe directly:

<iframe src="https://peptide-calculator.com/?embed=1" style="width:100%;height:1180px;border:0" title="Peptide Calculator" loading="lazy"></iframe>

What your readers see

The calculator only: inputs on the left, the live result and syringe graphic on the right, the math and water-fill panels, and a one-line "Powered by peptide-calculator.com" credit. Your page keeps its own header, navigation and footer. The widget resizes itself to fit.

Terms, short version

Free for any site. Keep the credit line. Do not present it as your own tool or remove the disclaimer. It performs arithmetic on numbers your readers enter and does not recommend doses; please don't wrap it in copy that does.

Common questions

Is the embed free?

Yes, for any website. The only requirement is the credit line under the widget, which the script adds automatically.

Does it slow my page down?

The widget loads lazily in an iframe after your page renders, so it does not block your content.

Can I embed a specific compound's calculator?

Yes. Add data-calc with the page name, for example data-calc="tirzepatide-reconstitution-calculator".

Does it track my visitors?

The calculator inside the iframe runs its own anonymous analytics (page view and clicks inside the widget). Nothing is read from your page.

About this tool. Built and maintained by the team at ThePeptideStore. The arithmetic is the standard U-100 reconstitution formula (concentration = mg ÷ mL; mcg per unit = concentration × 10; units = dose ÷ mcg per unit) and every result is recomputed live in your browser; nothing you enter is sent to a server. Reviewed 2026-09-02. This calculator does arithmetic on numbers you type. It is not medical advice and does not recommend any dose.
