This disclaimer is part of the agreement. It is incorporated into the terms of service, and the limitations in sections 16 and 17 there apply to everything on this page.

Nothing here is medical advice

No record, grade, tier, calculation, ranking, generated answer, forum post or anything you save in your own account is medical advice, diagnosis, treatment, a prescription, or a recommendation to obtain, take, avoid or stop anything.

We are not a licensed medical provider. We have no relationship with you, we know nothing about your history, your medications, your conditions or your circumstances, and we cannot acquire that knowledge from anything you type into a calculator or a profile field.

Check with a qualified clinician who knows your history before making any decision about your health, and in addition to — never instead of — anything you find here.

No professional relationship of any kind

Using the service, holding an account, paying for a subscription, posting in the forum or corresponding with us creates no doctor–patient, clinician–patient, nurse–patient, pharmacist–patient, researcher–subject, advisor–client, coach–client or fiduciary relationship between you and Stratum Applications Corporation or anyone acting for it. Nobody working on the service is your healthcare provider, and none of them is holding themselves out as anyone's.

Reporting is not recommending

Every dosing figure on this site is a report of what a source stated, carried with the label the source gave it and the evidence rung it earned. Where a record says 250–500 mcg, that is a sentence about a document. It is not an instruction to you, it is not a range we endorse, and it is not evidence that the figure is safe, effective or appropriate for anybody — including the population it was drawn from.

Where we hold no dosing information, the record says so rather than estimating. Where the only evidence is an animal study, the record says that too, and the rubric defines exactly what that rung does and does not license anyone to conclude.

What the calculators do, and what they do not

The reconstitution calculator converts a vial mass and a diluent volume into a concentration, and a dose into units on a syringe barrel. The beyond-use calculator applies published handling conventions for the diluent. The co-formulation check reports what the record says about two compounds sharing a vial, including when it says nothing.

They perform arithmetic on the numbers you supply. They do not choose a dose. They have no opinion on whether the number you typed is a good idea, whether the vial contains what its label claims, or whether any of it is appropriate for you. Arithmetic performed on a wrong input produces a wrong answer, confidently and without complaint. Confirm every draw against the vial in front of you.

Corbin is a language model

Corbin generates text using a third-party model. It can be wrong, incomplete, out of date, or confidently fabricated — including when it cites something, and including when it sounds certain. No human reviews its answers before you see them. It is not a clinician and it is not a pharmacist, and everything on this page applies to it in full. Verify anything that matters against the underlying record, which names its sources so that you can.

Most of these compounds are not approved medicines

A minority of the records carry an approval from a medicines regulator. Most do not. Many of these compounds are sold for laboratory research use only, which is a legal category rather than a comment on safety, and several have no human safety data at all — a fact stated on those records rather than left for you to infer.

Legal status for purchase, possession, import, supply and use differs between countries and changes over time. Nothing here is a claim that any compound is lawful for you to obtain, possess or use, and determining that is your responsibility alone.

What we do not know is published too

Fields across the corpus are recorded as not on file rather than left blank, because a blank invites you to fill it in from the surrounding text. If a record looks thin, that is the record being honest about a thin literature. An absent field is not an implied zero, an implied safety, or an implied anything.

These are injectable substances and the risks are real

Reconstituting and injecting substances carries risk of contamination, infection, injection-site injury, dosing error, allergic and adverse reaction, interaction with medicines you already take, and serious harm including death. Sterile technique, storage, beyond-use dating and disposal all matter, and none of them is supervised by us.

To the fullest extent permitted by law, you assume all risk arising from any decision you make in connection with the service, and you agree that you are not relying on the service as a basis for any such decision.

In an emergency, do not use this service

If you think you are having a medical emergency, an adverse reaction or an overdose, call your local emergency number — 911 in the United States, 999 in the United Kingdom, 112 across the European Union — or go to an emergency department. Do not wait, do not consult a record, and do not ask Corbin.

The vendor directory is not a safety assessment

Listings, scores and rankings describe published information about third-party sellers. They are not a verification of any seller's identity, licensing or lawfulness, and not a warranty of what any seller actually ships, of its identity, purity, potency, sterility or labelling. We do not test products. See section 12 of the terms.

If something here is wrong

Tell us. Every grade names the phrase it was derived from and every claim names its source, specifically so that a mistake is findable rather than arguable. We correct errors and say that we did. That is a practice we intend to keep, and it is not a warranty — see section 16 of the terms.

These three documents are one agreement, effective 19 August 2026: the medical disclaimer, the terms of service and the privacy policy. The disclaimer and the privacy policy are incorporated into the terms, so accepting one accepts all three.
