SWM, Biotest has recently released Spike in a liquid form called the Spike Shooter, and it's 8oz of pure T-max and it hits you in about minutes. Spike has a very clean feel and it doesn't cause jitters nor does it drop you like a ton of bricks as caffeine and sugar will do. This is a great supplement that not only improves focus but can increase strength 5-20% in a given workout. It causes your CNS to fire more rapidly and efficiently. It really is an awesome supplement and I use it regularly.
