What this tool is

Peptide Dose Tool performs unit arithmetic on numbers you type in. It converts between milligrams, micrograms, millilitres and insulin syringe units, and reports how many doses a vial contains at the concentration you describe. That is the whole of what it does.

What this tool is not

It is not medical advice, and it is not a substitute for a qualified healthcare professional. It does not recommend a dose, endorse any compound, or express any view on whether a substance is safe, effective, legal or appropriate for you.

Many of the compounds people use calculators like this for are not approved for human use in most countries and are sold for laboratory research only. Whether you may lawfully obtain or use any particular substance is a question for you and the law where you live. We take no position on it and provide no guidance on sourcing.

Check the output

Arithmetic is only as good as its inputs. Entering milligrams where you meant micrograms, or assuming a U-100 syringe when yours is U-40, produces a confidently wrong answer. Always check the result against the vial in front of you and the markings on the syringe you are actually holding before acting on it.

We have tested the calculation against hand-worked examples and believe it is correct, but we do not warrant that it is free of errors, and you use it at your own risk.

The Android app and subscriptions

The Dose Tool app for Android does the same arithmetic as this site and also keeps a log of what you enter. Everything above applies to it: it is a calculator and a record, not advice, and it never suggests what or how much to take.

The app requires a subscription, sold through Google Play. The price, the length of any free trial and the renewal period are shown on the purchase screen before you confirm. Subscriptions renew automatically until you cancel. You can cancel any time in Google Play → Subscriptions; if you cancel during a free trial before it ends, you are not charged. After cancelling, the app stays unlocked until the end of the period you paid for. Refunds are handled by Google Play under its refund policy. The calculator on this website remains free and does not require the app.

Availability

The site is provided as is, without any guarantee of uptime, accuracy or fitness for a particular purpose. We may change or withdraw features at any time.

Liability

To the fullest extent permitted by law, we are not liable for any loss, injury or damage arising from use of, or reliance on, this site. Nothing in these terms limits liability that cannot lawfully be limited.
