Concentration calculator
Research use only. Not for human or veterinary consumption. 18+.
Amount in the vial, volume of solvent added, concentration out. It runs in your browser and nothing is sent to us.
What this does and does not do
It divides the amount by the volume. That is the whole calculation, and it is worth stating plainly because the arithmetic is not where mistakes happen — they happen when the volume actually added was not the volume intended, or was never written down.
It does not convert between international units and mass. An international unit measures biological activity, so that conversion needs a potency figure for the specific material and cannot be done from the label. HCG is the line in this catalogue sold in units.
It contains no dose and no route, and we cannot advise on use of any kind. See our research use policy.
