Love this one.

Again. Another great tasting well refined shroom. Mixes well in coffee and starting to feel the effects after 6 weeks.

Improved sleep!

Tried a lot of different things to help with sleep and this seems to be helping. It's only been 3 weeks but I feel my quality of sleep has improved. Also feel it's helping to calm my nervous system through the day. Would highly recommend.
