Of the eight ingredients, tribulus alone comes with a number.
Standardization describes the extract: 45% of it is saponins, the group of compounds measured. It does not say how much extract is in each gummy, so you cannot work out how many milligrams of saponins you get.
It is a sign that someone defined the extract, which is better than nothing.
Research on tribulus is mixed, and a specification does not change that. It also says nothing about the other seven ingredients. Ask for the per-gummy amount, and treat tribulus as one component of a formula, not the reason to expect a result.
