Of the eight ingredients, tribulus alone comes with a number: standardized to 45% saponins.
Standardization describes the extract: it says 45% of the extract is saponins, the group of compounds the maker measures. It does not say how much extract is in each gummy, so you still cannot work out how many milligrams of saponins you get.
It is a good sign that someone defined the extract, and a half step toward transparency.
Research on tribulus is mixed, and the brand's own page discloses that. A specification does not change that evidence, and it does not tell you about the other seven ingredients. Ask for the per-gummy amount, and treat tribulus as one component of a larger formula, not as the reason to expect a result.
