Yeah someone also brought up that its not a linear scaling. https://pmc.ncbi.nlm.nih.gov/articles/PMC4804402/

And the study calculates it a 5mg for rats as 25mg for humans.

It's 5 mg/kg (or 15 mg/kg due to faster metabolism) for rats, and 25 mg (not per kg!) for humans. To be clear, 25 mg is a completely normal dosage that has been used in previous human studies.
