Caffeine

Caffeine increases cyclic AMP and is well-known for its research-backed effects boosting energy and metabolism and potentiating other stimulants and fat-loss ingredients.* Learn More

L-Tyrosine

L-tyrosine is a naturally occurring amino acid used by the brain to make stimulatory neurotransmitters that improve memory, mood, focus, libido, coping ability, and sense of well-being. L-tyrosine supplementation leaves people feeling refreshed after training or manual labor by mitigating some of the short-term stress caused by intensive work.*

NOTE: N-acetyl-L-tyrosine is a more water-soluble form of the amino acid L-tyrosine* Spike Shooter®, Spike® Hardcore Energy, and Spike® Double Shot formulas contain N-acetyl-L-tyrosine. Power Drive® powder contains L-tyrosine. Learn More

Yohimbine

Yohimbine is an aphrodisiac, stimulant, and potent fat-burning agent, especially in the belly, hips, and thighs.* It's a potent alpha-2 adrenergic antagonist. Antagonizing (or blocking) these receptors, Yohimbine enhances fat loss in otherwise resistant areas of the belly, hips, and thighs.* Learn More

I buy energy supplements all the time. Do I really have to limit myself to one can of Spike Shooter per day?

Yes. The Spike Shooter® formula is potent. That's why it's the favorite for hardcore fans who claim they "can't feel" other energy products. Do not exceed one can daily.
