20 Boxes x 20 sachets = 400 servings/cups of coffee. I have been using this for several months after a friend recommended it. I have fibromylgia and arthritis and used to be in a lot of pain and unable to do things or even let my husband put his arm on my shoulder while watching TV on the couch. After arguing about spending the money, we prayed about it and finally tried it.My results:- 1 cup every morning- after a few days woke up pain free- drink it all in about 10 minutes so do get some gas/burping- 3-1 means it has coffee, creamer & sugar all in it together- something about the combination of Gano Exel works as we tried taking plain reishi tablets and it didn't help- I ran out of it and all of a sudden everything hurt again - one day back with it (thanks, Amazon prime!) and my pain was gone- previous I had pain when people touched me, my knee would give out from arthritis, my fingers hurt writing, etc- I only take one a day in the morning, with a Power Bar or alone, and finish it in 10 minutes- easy - pour hot water over the powder and its ready, simple as hot chocolate- about me- age 52, diagnosed fibromyglia, arthritis, 5'8" tall, 220 poundsMy Husband -- age 67, also osteoarthritis, club foot, knee replacement- takes one cup of coffee and sick all day like he has the flu- he tried it various times and every time got sick/allergic reaction, sinus plugged, etc.So it doesn't work for everyone - if you are allergic to reishi mushroom, don't take it. If you aren't sure, I'd recommend doing like we did and start with on box. It usually starts to work in 3 days most people say. And it may cause some burping which is normal. God bless you and we hope you find a cure for your pain. God used this product to help me be able to live pain-free again without dangerous pain meds.
