I found the full text of the reishi 5-AR inhibition paper. The doses they used in rats were either 0.3% of diet as unextracted mushrooms or 1.5 mg/kg of the extract.
1.5 mg/kg divide by 6.2 going from rats to humans times 70 kg human = 17 mg extract. A gram of Swanson's best extract has 80 mg of triterpenes (which do the 5-AR inhibition), so it should work.
For unextracted mushrooms, 0.3% of diet = 3000 mg/kg diet. A rat eats 5 g diet per 100 g body which makes it 150 mg/kg. Divide by 6.2 times 70 kg human = 1.7 grams mushrooms.
