Psilocybin is relatively stable, but it degrades when exposed to heat, light, and oxygen. Proper storage is essential to maintain the potency of your mushrooms.The Golden Rules of StorageKeep it Dark: UV light breaks down psilocybin. Store in an opaque container or a dark cupboard.Keep it Cool: Room temperature is fine, but the fridge or freezer will extend shelf life significantly.Keep it Dry: Moisture is the enemy. Ensure your mushrooms are "cracker dry" before storing, and use silica gel packets in your jar.Stored correctly in a mason jar with an oxygen absorber, your mushrooms can retain full potency for over a year.
