Black Insomnia Ground Coffee - The Strongest Coffee in the World - 1lb (Dark Roast, 1 Pound)

Good coffee as advertised I thought I was going to do from how fast my heart was beating

Only way to wake up if your a coffee lover like me, get you a bag of this you won't regret it!

Thought I'd have to add sodium to it too mild the pucker factor, it is actually surprisingly smooth as is

Lots of caffeine, and good tasting. Will order again.

Flavor was good but couldn’t tell much of a difference between this product and death wish coffee

In doing research for very strong coffee, Black Insomnia came up consistently at the top (or 2nd) for caffeine content. I have a very high tolerance for caffeine, so I'm not easily impressed. This brand, however, comes through for me. I don't feel a sudden jolt or get shaky, but I can feel my energy level surge and sustain for about 6-7 hours. Those who are sensitive to caffeine may need to go slow on drinking this, but I don't see it as a brand that's going to give you heart palpitations, for example. In addition, I have to say I find it rather smooth instead of bitter or biting. Overall, a good buy and good value.

I’ve replaced my preworkout supplement with the coffee, and it’s one of the best decisions I’ve made! All of the caffeine, without the crap!

I bought this coffee to see if it would give me a little boost when needed. Man, did it come through.When needed I use this 50/50 with me regular blend so as not to get me over stimulated.
