Product analysis

40 out of 100

Steel-Libido Pink For Women combines botanicals with theanine, which has limited support for selected thinking tasks. Its largely unspecified ingredient forms and undisclosed herbal blend make the formula harder to judge.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality24

Most ingredient preparations are unspecified, including the plant part used for eleuthero. Ashwagandha is identified as a leaf-and-root extract, but the broader formula cannot be compared confidently for quality.

Ingredient Transparency52

Listed amounts are disclosed, but almost all ingredient forms are missing. The herbal blend also omits its components, leaving the full composition unclear.

Value For Money43

Theobromine offers favorable serving value, but theanine is expensive for the amount supplied. Eleuthero sits in the middle, while value for much of the botanical mixture remains uncertain.

Customer Satisfaction65

Customer feedback is favorable, with the number of ratings offering some perspective on satisfaction. Ratings do not establish effectiveness or safety.

Product Focus28

Support for thinking tasks is limited, and the theanine amount is below the exposure behind the cited findings. The large botanical mixture and undisclosed blend do not establish broader benefits.
