Green Apple is the best!
Set name: Warheads Sour Green Apple
Love these, I am subscribed for every two weeks, they last me one a day at work until the next shipment. Yay! Green sour apple is just the best. It’s slightly sour and refreshing. I work graveyard and stay awake all night with one of these. Super effective, great value for the money since I’m getting them cheaper this way than buying one a day at the convenience store next to my house. They’re sugar free but use sucralose, which is wannabe sugar but still, I’d say better for me (pre-diabetic) than real sugar.

Red Berry Drink
Set name: Sour Patch Kids Redberry
I drink one of these red cans when I get to the shop in the mornin. The taste reminnd me of the candy my kids liked when they were small. It has a sour kick at first but a sweet taste comes next in my mouth. I feel awake after I finish the can. My focus stays sharp while I work on the mashines for a few hours. I do not feel jitters in my hands or my chest like I do with some coffee. The liquid has no color which is fine with me because it does not stain my teath. I keep the pack in the small fridge in the garage to keep them cold. It is a good choice for days when I have a lot of heavy labor to do. My brother tried one and he thought the flavor was tart but I think it is right. I do not feel a crash when the afternoon comes. It is a way to get energy for my shift. I like that the cans are tall and hold much to last a while. My wife says I look alert when I use them before our walk.

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.
