Doses used in the Mayo Clinic trial was about 1.5g to 2g for humans, 5 days per month, iirc. Also keep in mind that if you are young and healthy you won’t notice much and it’s the kind of treatment like most that are long-term, meaning you can’t do it 3 months and expect results.

I don’t recommend this, nor have I tried it: Some people experiment with high doses, like 1-2g, within one day, twice a week. Anecdotal reports of scars fading, but also scary effects like hypocoagulation (won’t stop bleeding). Just internet rumors though, I‘d wait for clinical studies.
