Not medical advice

This is educational arithmetic on figures entered by the reader. It is not medical advice, not a dosing protocol, and not a recommendation that anything be prepared, obtained or administered. Nothing anywhere on The Peptide Calculator is medical, clinical or pharmaceutical advice, and nothing here is a substitute for it.

A question about anyone’s health belongs with a licensed clinician who can examine the person asking. A decision about anyone’s health taken on the strength of a page on this site is taken against the explicit advice of this notice.

No amount is stated, recommended or implied

Nothing here states what quantity is appropriate for anyone, and there is no function in it that produces an amount to administer.

That is a structural property of the software rather than a policy applied on top of it. The calculation engine behind this site holds no compound data beyond molar masses, has no model of a person, and contains no function that accepts a person, a goal or a condition and returns an amount. Every entry point requires the reader to supply the quantity, and converts between representations of what the reader already stated. Mathematics on a figure somebody else chose is a converter, and a converter cannot recommend.

No page here states a frequency, a schedule, a route, a duration, a per-kilogram figure or a protocol of any kind, and no page describes how to prepare or administer anything. The arithmetic of a volume is not an instruction to draw it.

Nothing here is a recommendation to obtain or use anything

This site does not recommend that any substance be purchased, imported, possessed, prepared or administered, by anyone, for any purpose. It names compounds because arithmetic needs something to be arithmetic about, and naming a compound is not a suggestion that anyone acquire it.

No supplier, vendor, pharmacy, compounder or source is named, ranked, linked or implied anywhere on this site, and there is no route from any page here to buying anything.

Regulatory status

Most compounds named here are research chemicals that are not approved by the FDA for human use.

Each compound page reproduces, word for word and with its retrieval date, the result of an automated query against a public drug application register. That sentence is a finding about a register query on a date. It is not legal advice, not a jurisdiction-by-jurisdiction legality assessment, and not a statement about what is lawful anywhere.

What is lawful to possess, import, supply or administer differs from one jurisdiction to the next and changes over time. Nothing on this site is an assurance that anything described here is lawful where a reader is.

An exact calculation is not an accurate measurement

An exact calculation is not an accurate measurement: what is actually in a syringe depends on the preparation and the device, neither of which this page can see.

The arithmetic here is exact: values are held as whole-number fractions and rounded once, at the point of display. That precision describes the calculation and nothing else. It says nothing about whether a vial contains what its label claims, whether a solid dissolved fully, whether a barrel is accurate, or whether a figure was read correctly off it.

Where the inputs do not support an exact answer, the page says so rather than rounding the uncertainty away. A concentration computed without a measured final volume is labelled an upper bound, a value that cannot be read on the barrel in use is flagged as unreadable, and a half-life curve is labelled approximate because the function behind it is.

Who checked this, and who did not

No qualified clinical reviewer is recorded against this site, and no credential is claimed anywhere on it. The arithmetic is covered by an automated test suite and by mutation testing, which introduces deliberate defects and verifies the tests catch them. That is evidence about the software, not clinical review, and the two are not substitutes.

No contributor here is presented as a physician, pharmacist, chemist or researcher, because none is. No personal byline, qualification, affiliation or certification appears anywhere on this site, and none is claimed in its structured data.

The molar masses and identity fields are a dated copy of fields from public chemical records, which are linked so they can be read at source. The record is the authority; this site is a copy with a date on it.

Error, and how it is handled

Software at this scale carries error. A figure that does not match the record cited for it is wrong and is corrected against that record. An arithmetic result that can be shown to be incorrect is a defect, and the test suite exists so that such a defect fails the build rather than reaching a reader.

The site is offered as it stands, with no warranty of accuracy, completeness or fitness for any purpose. Anyone relying on a figure from this site for anything that matters should check the arithmetic independently, which is why every page shows its working.
