Arithmetic only
The calculators convert between milligrams, micrograms, milliliters and syringe units from numbers you enter. They don't know what a vial really contains, whether it's pure or fully dissolved, or whether a quantity is appropriate for anything. A correct conversion of an inappropriate number is still inappropriate.
Research use only
Many compounds named on this site are sold as research chemicals that are not approved by the U.S. Food and Drug Administration for human or veterinary use. Their presence here describes the arithmetic of reconstituting a lab vial. It isn't an endorsement, a claim of safety or effectiveness, or a suggestion that they be used in people or animals.
Prescription products
If you have a prescription medicine, follow its label and the instructions of the prescriber and pharmacist who supplied it. Don't use this site to change, check or reinterpret prescribed instructions.
Accuracy
We test the math (see methodology) and check facts against primary sources, but we can't guarantee the site is free of errors. Double-check any figure by hand before relying on it. Peptide Vial Math is provided as-is, without warranties, and the operator isn't liable for decisions made using it, to the extent the law allows.
