My dosing protocol is this:
Lion's mane by Host Defense: 3 grams, 10 minutes before ingesting Niacin.
Dried Psilocybin mushrooms (Cubensis): 300 mg, taken at same time as Lion's Mane.
Niacin: 500 mg, ten minutes after ingesting mushrooms.
Note: adjust dosages as needed. Especially for Psilocybin and Niacin. A microdose of shrooms should cause no perceptual changes. Periodically take a break from these as tolerance quickly builds. Take enough niacin to induce a flush response. Eventually you will need to increase the dose to get a flush response. I don't know what the maximum safe dose is but I personally won't take more than a gram / day. Once I stop getting a flush response @ 1 gram, I will take a break until my tolerance goes back down.
Other supplements I take: Magnesium, Vitamin D, B complex, CBD, nigella sativa, chlorophyllin.
Other supplements that increase BDNF (brain derived neurotrophic factor) (related to NGF, nerve growth factor): organic citrus peel extract, organic xiao yao san ('san' means powder) / xiao yao wan ('wan' means pill), organic whole coffee fruit extract, organic turmeric/curcumin with black pepper/piperine, MEDITATION AND YOGA.
