This really is clean coffee, I noticed multiple changes in my energy and cravings. No more cravings. I normally go for a dark Ethiopian coffee but I actually really enjoyed this one. Now on a side note.... I have this enormous black chicken who steals my coffees most stealthily. If I'm in a rush or too dirty to make a proper coffee I usually make a quick Moccano. Well, since my chicken has tasted the bulletproof coffee my Moccanas are safe. She wouldn't touch it and I get a rude peck and lots of loud complaining.
Been using Bullet Proof Coffee for years but this was my first try of the Mentalist. Love it! 💯💪❤️
Taste awesome and great to no it has no toxins
tastiest, cleanest, rich in flavours ! simply he best!!!
Fantastic product it’s the only coffee that I use. Having a chronic illness I’m allergic to mould and other toxins. This is such a clean and ethical product , when you have a very restricted diet it’s one thing I can enjoy without wondering will I have an adverse reaction to it !
