Three units is at the edge of what a barrel can tell you
The larger listed volume gives the bigger draw and it is still only three units. A one-unit difference is a third of that draw. The spacing and width of printed lines depend on the syringe, so the illustration cannot establish how precisely a particular device measures it.
The two examples show how the reading changes with volume: the more dilute example increases it from two units to three. That arithmetic is not a direction to prepare or inject the capsule amount.
A hundred doses is a supply question with no answer
The example contains a hundred portions before handling losses. Two portions a day would be fifty days by division, but the cited study used capsules for two weeks, not repeated injections from a stored solution.
The count therefore does not establish a fifty-day injection course or a storage period. A portion count and a study duration answer different questions and must not be substituted for one another.
The published amount was swallowed, not injected
The quantity this table divides was given as a capsule, twice a day, in the one human study that printed a number. That study does not establish an injection dose or validate a preparation for use under the skin.
So this page computes what the arithmetic says and no more. It is the draw a hundred micrograms makes from this vial, not a recommendation that anyone draw it.
