Peptide labels use several kinds of numbers. Milligrams describe mass: the amount of a named substance. Read the unit beside the number instead of relying on the largest print on the box.

Millilitres describe liquid volume. A thirty milligram pen label does not, by itself, tell you the volume inside. Total content and liquid volume need separate fields in your comparison.

Here is label arithmetic, not a use instruction: twelve milligrams in three millilitres equals four milligrams per millilitre. You need both quantities to calculate the concentration of that example solution.

For a blend, read every component. Ten milligrams plus ten milligrams makes twenty milligrams combined. It does not mean either ingredient is present at twenty milligrams in the product.

A dial marking belongs to the specific device and formulation. Do not turn the concentration example into a click setting, or borrow another pen's table to fill a missing instruction.

Finally, compare the order, the actual label and the relevant batch document. Arithmetic can reveal inconsistent printed statements, but it cannot test the liquid. Ask the seller to resolve any mismatch.
