| Standard Dose | 750-1500 mg/day divided into 2-3 doses | 500-3000 mg/day of fruiting body extract (standardized to >30% polysaccharides) or 1000-3000 mg/day of mycelium extract (erinacine-enriched) |
| Timing | With fat-containing meals (fat-soluble compound; bioavailability increases significantly with dietary fat) | Morning or split morning/afternoon. With or without food. Effects are cumulative — expect 2-4 weeks before noticeable cognitive benefit. |
| Cycle Duration | Cycles of 8-12 weeks on, 4 weeks off | Ongoing; no cycling strictly required, though some users cycle 8 weeks on, 2 weeks off |

Potent positive allosteric modulator of AMPA receptors with 5-10x the potency of piracetam, slowing both channel closing rate and microscopic desensitization rates. Also modulates metabotropic glutamate receptors (mGluRs), activates nicotinic acetylcholine receptors, and indirectly boosts dopaminergic and serotonergic neurotransmission, conferring anxiolytic properties.

Contains hericenones (fruiting body) and erinacines (mycelium) that stimulate nerve growth factor (NGF) synthesis in glial cells via activation of the JNK pathway. Erinacines cross the blood-brain barrier via passive diffusion and act as potent neurotrophin-stimulating compounds, activating the TrkA receptor and downstream ERK1/2 signaling cascades to promote hippocampal neurogenesis and synaptic plasticity. Also demonstrates anti-inflammatory activity through suppression of NF-kB and upregulation of BDNF expression.
