What You Should Know
Stacker 2 Yellow Hornet is an ephedra-free version of an energy supplement that was once very popular. The original formula for Yellow Hornet contained ephedra, but when ephedra was banned Stacker, along with most other companies, reformulated supplements to remove the ephedra. The reformulation meant adding other stimulants to the mix to try and mimic the ephedra effect. In most cases, synephrine was used for this purpose, but Stacker 2 chose to combine yohimbine, yerba mate, guarana, kola nut and quite a large amount of caffeine. This supplement is not safe for the average dieter as it will cause nausea, jitters, shakes, racing heart rate and possibly increased blood pressure. If you are currently taking any prescription medications it is best to skip this supplement all together.
List of Ingredients
- Yohimbine Alkaloids
- Yerba Mate
- Kola Nut
- Caffeine Anhydrous – 300mg
Yohimbine, yerba mate, guarana, kola nut and caffeine are all stimulants. There is a whopping 300 mg of caffeine per dose of Stacker 2 Yellow Hornet. Over the counter anti-sleep medications tend to have about 200 mg per dose and those are known to cause negative side effects and, by definition, prevent sleep. Stacker 2 Yellow Hornet packs an additional 100 mg of caffeine and four other stimulants into the mix. The end result is longer lasting caffeine high that may leave the dieter feeling more sick than energetic.
Caffeine is proven to boost metabolism, but taking more caffeine does not increase this effect. Ideally, the dieter can consume as little as 75 mg of caffeine and metabolism will increase. Many dieters consume more than that in the first cup of coffee each morning. Caffeine has a lifespan of 12 hours, so taking this much caffeine means after 6 hours there will still be 150 mg of caffeine left in the body. Even if the dieter takes the supplement early in the day, they could still have trouble sleeping at night.

Stacker 2 Yellow Hornet may no longer contain ephedra, but the company sure packed in the caffeine and stimulants. This is not a safe alternative to proven fat burners and we found no free trials available so a dieter could take a dose to judge how the body reacts.
