I’ll buy it again.
Set name: Warheads Sour Green Apple
Ghost is very good. Especially comparing it to other energy drinks that literally tingle your whole body if you drink it too quickly. When I’m looking for energy drinks I really want more focus and mental energy over simple caffeine high and energy. This does give me both. In a good way. It has been very effective in what it says it does. Definitely value for the money over buying it at the gas stations one by one. Buying it in bulk definitely cuts the cost down. Energy levels peak very well without a crash at the end. The ingredients seems to be very good because my body doesn’t feel heavy afterwards.

Daily Drinker Warning: Great Energy, but Watch Your Teeth!
Set name: Orange Cream
No sugar which is great and this energy drink has become a staple but it is also very acidic so watch out if you have very thin teeth like me. I often find it increasing my sensitivity by a lot so a sensitivity toothpaste daily is essential for me since I drink these daily. The feeling or energy from these is great, I have been drinking similar ones like G fuel for years and this gives me significantly more energy. A quick tip though is many dollar trees have Gfuel available so if you need sugar free energy drinks like me, they provide cheaper deals - currently dollar tree has G fuel for 1.25$ a can which is quite cost effective compared to Ghost. Drinkability is mixed with Ghost, they are strong drinks. I often find G fuel being very refreshing and enjoyable while Ghost is very concentrated. Comparison - Gfuel vs. Ghost ingredients and focus Ghost: Focus - Cognitive function, energy metabolism, and premium/transparent sourcing. Caffeine - Natural from coffee beans Nootropics - Alpha-GPC, NeuroFactor™ Coffee Fruit Extract. Performance - Carnipure® L-Carnitine L-Tartrate, Taurine. What makes it unique - AstraGin® (absorption enhancer), transparent proprietary blends. Sweeteners - Sucralose, Acesulfame Potassium. Gfuel: Focus - support for focus and antioxidants. Caffeine - synthetic Nootropics - L-tyrosine and L-theanine Performance - Taurine, L-citrulline malate What makes it unique - Extensive Antioxidant Complex, high dose of Vitamins C, E, and B-vitamins. Sweeteners - Sucralose, Acesulfame Potassium. The bottom line here: G Fuel for maximum boost and vitamins; Ghost for premium, clean, and focused energy. Ghost is mostly proprietary blends of vitamins which is something to keep in mind since we do not know what is in them while G fuel is more transparent for the most part. I recommend trying both and seeing what works best for you.

Best Blue Raspberry energy drink out there!!
Set name: Blue Raspberry
I've tried multiple different brands of energy drinks that have blue raspberry as a flavor. My absolute favorite was the C4 Jolly Rancher Blue Raspberry energy drink..... UNTIL I tried this one. Beats it for sure. It has such a sweet, smooth and refreshing taste and gives a solid boost to power me through my day. The price is a little high but in all honesty it's worth the money! No crash or jitters after one of these and this is coming from someone who drinks lots of caffeine every day. TL;DR absolutely worth a try!!

Great flavor and solid energy boost
Set name: Cherry Limeade
By far my favorite flavor in any energy drink. GHOST really does this one well and the Cherry Limeade tastes great compared to a lot of other energy drinks I’ve tried. Yes, it is high in caffeine, but that’s actually what I need sometimes for a real energy boost, and this one does the job without feeling overly heavy. The calorie content is also great if you’re someone who watches calories, which I appreciate. Overall, great flavor, solid energy, and one of my go-to energy drinks.
