Micromex is a brand new Truffle! It is a hybrid of Mexicana and Pajaritos and is mostly used for microdosing.
Micromex is rather strong and can be overwhelming for beginners. You should not ingest more than 7,5 grams at a time.
First effects are likely to be felt after around 10-30 minutes and can last up to 6 hours.
You can eat Truffles or use them as a tea (let it simmer for 20 minutes, don't let the water boil).

BE AWARE that these amounts are averages and can vary from person to person. Always start with a low dose.
