PX Black is a Finaflex supplement that packs quite the stimulant punch. According to the ingredient list, there are at least four sources of stimulant in the formula. Taking multiple stimulants, especially when the company does not bother to list how much caffeine is included in each dose, can lead to dangerous side effects.

Consumers can find PX Black for sale from multiple websites, including the official Finaflex website and Redefine Nutrition, the manufacturer. Prices vary, but you can expect to pay about $30 to $45 per bottle.

Product Features

What does it take to boost metabolism and increase weight loss using a dietary supplement? The answer is simple – stimulation. Most diet supplements contain some form of caffeine or other stimulant. The stimulant increases heart rate and the dieter feels more energetic so the body burns more calories – in layman’s terms. However, too much of a good thing can lead to dangerous medical side effects.

PX Black contains caffeine, but the dieter is not told how much. Any more than 100 mg per serving is enough to cause jitters, shakes, anxiety and loss of sleep. There is likely more than 100 mg of caffeine in one dose of PX Black. Moreover, the company also packs in theobromine, green tea extract and Advantra Z – additional sources of caffeine and synephrine (stimulant).

Interestingly we could find no testimonials, reviews or before and after pictures from dieters who’d melted away the fat using PX Black. We did find a warning telling dieters not to use the supplement for more than 45 days straight.

PX Black is not a safe diet supplement for the average dieter. Bodybuilders tend to take high doses of caffeine, especially during the cutting or fat burning phase. This supplement may be ideal for bodybuilders, but the average dieter needs to know how much caffeine they are taking and a list of possible side effects associated with ingredients in the formula.
