What the evidence supports: raised testosterone in rats; no human trials exist.

This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.

How long to take it

Not established. There is no human evidence base to guide use.

Who it's actually for

Hard to justify. One of the clearest cases on this site of popularity running far ahead of evidence.

Practical notes

  • The testosterone claims come from rat studies, not people.
  • Animal data suggesting testicular toxicity is the main reason for caution.
  • If you're considering it for low testosterone, get a proper medical evaluation first.
