ich kenne die Seite sein l√§ngerem da dort ja auch unsere Vitamintabletten "All in One" die Dopingsubstanz DHEA enthalten sollen.
Wir haben die Leute geben, uns das entsprechende Gutachten vorzulegen. Das konnten sie bis heute nicht.
Momentan drohen wir mit Schadenersatzforderungen wenn Sie Ihre Behauptung nicht belegen. Daraufhin kommen komische Briefe, dass sie nichts in H√§nden haben, sondern es aus √Ėsterreich erfahren h√§tten und dass es ja nicht so schlimm w√§re, das es sich nur um eine Forschungsarbeit handelt. W√§re das ein seri√∂ses Institut, dann w√ľrden die solche Behauptungen nur machen, wenn Sie ein sauberes Gutachten h√§tten und von uns vorher ein Gegengutachten (wir haben f√ľr alle je produzierten Produkte R√ľckstellmuster und k√∂nnen jederzeit nachweisen, was drin und nicht drin ist) gefordert h√§tten. Alles ist nicht geschehen und die Leute haben nur ein Ger√ľcht.
Ein anderes Zeichen f√ľr die Qualit√§t des "Institutes" ist die l√§cherliche "Seminararbeit" √ľber BCAA¬īs (klick auf Nahrungserg√§nzugen, dort findest du sie). Hier ein paar Studien, die sich die K√∂lner Spezialisten mal einverleiben sollten: Peer-Reviewed Professional Journals

On two occasions, seven male endurance-trained cyclists performed exhaustive exercise on a cycle ergometer in the morning after they had performed a bout of exercise the preceding evening in an attempt to lower the muscle glycogen stores. The subjects exercised at a work rate corresponding to approximately 70% of their maximal oxygen uptake for 60 minutes, followed by another 20 minutes of maximal exercise. During exercise the subjects were given either a solution of branched-chain amino acids (BCAAs) or flavoured water (placebo). Every 10 minutes during exercise the subjects rated their perceived exertion and mental fatigue on two different Borg scales. During the 60 minutes exercise at a given work rate the subjects ratings of perceived exertion when they were given BCAAs were 7% lower, and their ratings of mental fatigue were 15% lower than when they were given placebo. In addition, the performance in the colour task of Stroops Colour Word Test performed after exercise was improved when BCAAs had been ingested during exercise, compared with the results from the placebo trial. There was no difference in the physical performance between the two trials measured as the amount of work done during the last 20 minutes of exercise when the subjects performed at their maximum. The plasma concentration ratio of free tryptophan/BCAAs, which increased by 45% during exercise and by 150% 5 minutes after exercise in the placebo trial, remained unchanged or even decreased when BCAAs were ingested.

This study investigated the effects of pre-exercise branched-chain amino acid (BCAA) administration on blood ammonia levels and on time to exhaustion during treadmill exercise in rats. Adult female Wistar rats were trained on a motor driven treadmill. After a 24-hour fast, rats were injected intraperitoneally (i.p.) with 1 mL of placebo or BCAA (30 mg), 5 min before performing 30 min of submaximal exercise (18 subjects) or running to exhaustion (12 subjects). In both cases, rats were sacrificed immediately following exercise, and blood was collected for the measurement of glucose, nonesterified fatty acid (NEFA), lactic acid, BCAA, ammonia, and free-tryptophan (free-TRP) levels. Control values were obtained from sedentary rats that were subjected to identical treatments and procedures (30 subjects). Plasma BCAA levels increased threefold within 5 minutes after BCAA administration. Mean run time to exhaustion was significantly longer after BCAA administration (99 +/- 9 min) compared with placebo (76 +/- 4 min). During exercise, blood ammonia levels were significantly higher in the BCAA treated compared with those in the placebo treated rats both in the 30-min exercise bout and following exercise to exhaustion. These data demonstrate that BCAA administration in rats results in enhanced endurance performance and an increase in blood ammonia during exercise.

This study found that female bicyclists reported lowered feelings of exertion following BCAA supplementation.

Physiologists often use BCAAs in various formulations to decrease central nervous system fatigue in athletes. Intake of BCAAs during or prior to exercise may delay exercise-induced or central nervous system-induced fatigue. The recommended dosages are 7,500 mg (for alleviating mental fatigue) and 16,000 mg (for improving physical performance in marathon runners). The author claims that BCAAs might improve running performance by assisting athletes to run harder and remain focused.
¬∑ Mittleman, K. D., et al. Branched-chain amino acids prolong exercise during heat stress in men and women. Med Sci Sports Exerc. 30(1):83-91, 1998.
To assess the effect of branched-chain amino acids (BCAA) supplementation on endurance performance in the heat, six women and seven men participated in two trials of rest in the heat (Ta = 34.4 +/- 1.8 degrees C; rh = 39 +/- 14%), followed by 40% VO2peak exercise to exhaustion. Subjects ingested 5 mL x kg(-1) of a placebo (PLAC) or BCAA drink every 30 minutes. Cycle time to exhaustion increased during BCAA (153.1 +/- 13.3 vs 137.0 +/- 12.2 min) for men and women. Plasma glucose was maintained at baseline values for both drinks; however, women had significantly higher concentrations (5.9 +/- 0.6 vs 4.0 +/- 0.2 mM). Plasma free fatty acids and ammonia were not influenced by drink or gender but increased over time. BCAA resulted in a significant increase in plasma BCAA (1209 +/- 119 vs 496 +/- 44 microM), while F-TRP (9.6 +/- 0.9 vs 12.0 +/- 1.3 microM) and F-TRP:BCAA were decreased (0.009 +/- 0.001 vs 0.024 +/- 0.003 ND) in both men and women. Cardiovascular and thermoregulatory data were similar between treatments for all subjects. Psychological data were not influenced by BCAA. These results indicate BCAA supplementation prolongs moderate exercise performance in the heat.

Und nun deine Frage:
Unsere Produkte enthalten keine Prohormone oder Verunreinigugen.
Du k√∂nntest nur von Tribulus Terrestris (optimiert k√∂rpereigenen Hormonhaushalt) und Lipodyn (enth√§lt Koffein und ist daher genau wie zu viel kaffee) positiv getestet werden.
