There's no need to dress this shit up so much. I've never tried Spike, I admit, but I doubt I ever will.
For the most part, I like Biotest. I think they're brand line is probably the most streamlined of any company out there. But then there's shit like this- part of their advertisement for Hot Rox Extreme:
This doesn't make any sense to me. How many middle-aged women post over at T-Nation? I mean, if I'm inferring correctly, and they designed this massive study, why in the fuck wouldn't they design it specifically for their client base? Forgive the cynic in me, but I see shit like this, and I always, inevitably think: "There's something rotten in the state of Denmark."
Guys, don't fall for this shit. If you want a stimulant, if you want to burn fat, why spend the extra money? We already know what PWNS:
Ephedrine (25mg) + Caffeine (200-400mg) + Aspirin (125mg) [optional, for weight loss, not stim]
And like Art, you shouldn't be drinking caffeine if you want the most out of a pre-workout stim. You also shouldn't be taking it every day, or if you do, you have to cycle off. You should cycle off periodically, regardless.
Vasopro or Biotek can be your ephedrine supply. They're like $7-9 for 50 pills. That covers 50 workouts. Caffeine is even cheaper.
Save your money.
