I felt as good the effect. I suppose otherwise no caffeine or other "uppers" to me and made me feel most busy after taking the Chargers.
Whether this effect is due to the ingredients of the Chargers or not, I can not say. Even if it is only a placebo effect, it is a beneficial effect.
The taste is there already the greater evil. Acidic to bitter, you have to like. The small amount (I mean it was 250ml) probably is not a problem.
What, however, I noticed: the Charger runs down like oil. Can be very pleasant to drink.
Caution is advised in the product description: this is probably a "Shake" and not from the Charger.
A year ago, I separated myself from the Charger and take before and during the units' Powerbar Isomaxx blood orange ". This is not quite as "sharp" me tastes much better and refreshed me like the Charger.
In general, the Charger is recommended, the stimulating effect is definitely greater than for example when Isomaxx.
When Bodyshaping program of the Powerbar Charger me has certainly helped very good.
1 star deduction for the taste ... otherwise: clear recommendation.
