Speed Stack by American Body Building is a strong stimulant drink that is supposed to be consumed before working out to give that burst of energy needed for faster reps and longer runs. Swollen muscles and monstrous pumps are claims made by the supplement manufacturer. The supplement contains only a few ingredients and only one will truly leave the dieter feeling “monstrous”. Speed Stack sells for $55.00 per 20 pack of 18 ounce bottles.

List of Ingredients

Arginine, Caffeine, Taurine, Guarana, Glycerol.

Product Features

We are going to start off with the Arginine. Arginine is an amino acid consumed from animal and vegetable sources. Arginine has no direct link to muscle building or weight loss as it is typically used in the body to heal wounds and boost immune function. It also plays a role in hormone release.

The big hitter is caffeine in Speed Stack. Every 18 ounces contains 300 mg of caffeine from caffeine anhydrous and guarana. The average cup of coffee has about 80 mg of caffeine. That means this supplement accounts for almost 4 cups of coffee with every container. Consuming 300 mg of caffeine in a sitting can lead to harmful side effects like increased heart rate and blood pressure. Some people may suffer from caffeine toxicity if they are sensitive to caffeine. Nausea is another major side effect.

Taurine is the next ingredient and there are no known energy boosting effects associated with Taurine despite its use in energy drinks from many suppliers. Taurine does have some function in the body, however, including maintenance of skeletal muscles and lowering blood pressure. This ingredient could be used to counteract the huge dose of caffeine.

The final ingredient is glycerol. Glycerol is probably used as the sweetener in this drink and though it has a glycemic index lower than sugar it contains calories just the same. One serving, or 1/2 bottle, contains only 15 calories.

The supplement is sold as a nitric oxide energy drink. There is no nitric oxide or nitric oxide complex included on the label, so why this designation is made we have no idea. Dieters should beware when taking this supplement that side effects can include racing heartbeat and feeling sick on the stomach. When combining high amounts of caffeine with exercise, the heart races even faster and can lead to more severe problems.

Advantages

  • The price for Speed Stack is lower than other comparable energy drinks. 

Disadvantages

  • Too much caffeine.
  • Ingredients will not increase fat burn.
  • Stimulants could cause nausea and vomiting.
  • Racing heart rate and increased blood pressure could be side effects.

Conclusion

We would like to advise dieters to steer clear of Speed Stack unless they are used to taking very high amounts of caffeine. Caffeine is a proven weight loss aid, but 300 mg per bottle is far more than the needs to boost metabolism. The remaining ingredients will have no real effect on muscle building.
