Medical Disclaimer

This site is not medical advice and is not a substitute for a licensed clinician. It performs arithmetic and reports what published documents say. It does not know your medical history, your medications or your circumstances, and it cannot tell you what to take.

What the calculators do

They convert between vial contents, diluent volume, concentration, injection volume and syringe units. That conversion is fixed arithmetic and is the same for any substance in any vial. The calculators do not validate that a dose you enter is appropriate, safe or legal — they compute the volume corresponding to the number you typed.

What the dosing information is

Where a compound has an FDA label, we reproduce figures from that label and cite it. Where a compound has no approval anywhere, we do not publish a dosing schedule; we list doses that appeared in named studies, tagged with the species and route. Reproducing a study dose is not a recommendation to use it, and doses given to animals do not convert to human doses. Read our sources and methodology for the full detail.

Unapproved substances

Several compounds covered on this site are not approved for human use in any country. Some are prohibited in sport. The FDA has stated that labelling a product “research use only” or “not for human consumption” does not change its legal status when the seller’s own marketing shows it is intended for people. Products bought outside a regulated supply chain have no verified identity, purity, sterility or potency, which means the milligram figure on the label — the number every calculation here starts from — may itself be wrong.

Accuracy

The calculation engine is covered by an automated test suite, and every published figure is traced to a named source. We still make no warranty that the site is free of error. Check anything that matters against the primary source we link to, and against your own vial’s labelling. If you find a mistake, say so — corrections get priority over everything else. The limits of liability are set out in the terms of use.

In an emergency

If you think you have taken too much of something, contact emergency services or a poison control centre immediately. Do not use a website to work out whether you are in trouble.
