## Features

- YOUR DAILY ROCKET FUEL — Each brew creates a delicious cup of flavorful, dark roast coffee with notes of chocolate and nuts. A potent blend that provides the spark you need to power even your most demanding days. We’ve paired this premium coffee with three amplifying ingredients: organic coffee extract, L-theanine and organic cordyceps mushroom extract. When busy doesn’t even begin to describe your day, this energy boosting blend, with about 190mg of caffeine per 12oz cup, helps you get it all done.
- HARVESTING THE ANCIENT ENERGY OF CORDYCEPS — Cordyceps were first discovered by sherpas of the Himalayan mountains. After trying these small, strange looking mushrooms, they could breathe easier at high altitudes, had a lift in physical energy, and had greater endurance. Today, Cordyceps militaris is used for the same benefits originally discovered by the sherpas, with loads of scientific research to validate the compounds responsible for its energizing effects. Each cup of our Perform concentrated coffee contains 500mg of Cordyceps.
- JUMP INTO HIGH GEAR WITHOUT THE JITTERS — One of our concerns when developing our high caffeine coffee was the extra boost would come with extra side effects. This is why we’ve infused this extra strong ground coffee with green tea extract to provide L-Theanine, an amino acid known for its extraordinary ability to balance out that caffeine surge.
- REMARKABLY ELEVATED COFFEE — Grown in the Marcala, La Paz region of Honduras, at 5,500 feet above sea level, these specialty-grade, single origin coffee beans brew a delicious, low acid coffee.
- SCIENTIFICALLY SPEAKING, THIS COFFEE IS PRETTY MUCH MAGIC — Functional mushrooms have been used around the world for centuries to improve productivity, immune support, and more. Unfortunately, the majority of the mushroom supplement market aren't mushrooms at all, but rather the mycelium (basically the root system). At Four Sigmatic, we bring only the best of nature to your daily routine, so we always use the mushrooms' fruiting bodies which contain 15x more active ingredients than the mycelium.

## Questions & Answers

**Q: Is it really coffee?**
A: Yes! It’s real organic Arabica coffee from small Honduran family farms. Third-party tested for mold, mycotoxins, pesticides, and heavy metals. Choose from various roasts, caffeine levels, and formats. No chemical processing - just pure, clean coffee.

**Q: Does it taste like mushrooms?**
A: Short answer: no! It tastes like smooth, rich coffee - not mushrooms. We start with organic single origin Arabica coffee and infuse it with organic mushroom and adaptogen extracts for all the functional benefits, minus the mushroom flavor.

**Q: How do I make your coffee?**
A: We offer a variety of formats so you can brew your way! We offer instant, ground, whole bean, K-pods, espresso capsules, as well as instant coffee latte mixes if you're looking for an all in one solution.

**Q: Where does your coffee come from?**
A: We work with USDA Organic small family farms in Honduras. High altitude, shade grown and water washed. No chemical processing!

**Q: Is this a coffee alternative?**
A: No! Our coffee products contain real organic Arabica coffee. We offer blends, protein powders, and capsules which do not contain coffee - but all of our coffee products contain real coffee.

### ⭐⭐⭐⭐⭐ Keeps me going all day - some times all night
*by B***S on 19 December 2024*

The 21g suggested dose must be an error. You need less than half of that or it tastes like mud and you’ll never sleep again.
