Geen idee of dit echt waar is, heb 't van het internet geplukt (en heb 't stukje amper gelezen).
BSN NO-Xplode contains caffeine which is banned by the NCAA. Caffeine will produce a NCAA positive drug-test if amounts exceed 15 micrograms/ml. in the urine sample collected. Unfortunately, there is not a formula to calculate how much caffeine consumed would result in a urinary concentration greater than 15 micrograms/mL. Varying metabolic rates and time of consumption prior to urine collection are contributing factors. It does take a relatively large quantity (generally a few hundred mg of caffeine a couple hours before a drug test) to cause a positive, but again it varies for each individual.
One scoop of NO-Xplode contains approximately 100mg of caffeine per scoop. The suggested serving size before working out is 1-3 servings (scoops). That would equal approximately 100-300 mg of caffeine per serving.
The NCAA bans caffeine because it is found to be a performance enhancer. The 15 micrograms/mL cut-off is designed to eliminate individuals from testing positive for caffeine because of the "normal" amounts consumed from average dietary intake. The cut-off is not designed to identify the most caffeine one can consume and still avoid testing positive (e.g.; using a supplement for performance gains).
A rule of thumb is that in a healthy and average sized man, the NCAA limit may be reached by consuming five regular cups of coffee (~100 mg caffeine per 8 oz) a few hours before drug testing. This is not a steadfast rule, as there may be variations of caffeine content in each product as well as metabolic differences unique to each athlete. Therefore, the safest action is to avoid consuming caffeine and caffeine-containing products during athletic events.
Dietary supplements that are sold over the counter and through the internet are under-regulated by the U.S. FDA. Therefore, we cannot guarantee the product's purity or safety. Impure supplements can cause a positive drug test under the NCAA drug testing program. Athletes are advised that the use of dietary supplements is at the user's own risk. The list of ingredients and claims made by a manufacturer are not necessarily backed up by reliable, scientific research. The REC DOES NOT recommend the use of any dietary supplement, please direct all dietary supplement questions to the REC.
