The most recent trial, published in the May 2004 issue of the Journal of Strength and Conditioning Research, also shows that Creatine Serum has little effect on performance.

A group of 11 competitive male athletes took 20 grams of Creatine powder each day and a placebo serum for six days. Seven weeks later, they received five milliliters of Creatine serum daily along with a placebo powder for the same period. A sprint cycling test was performed before and after the supplementation period.

Total work and peak power improved after the athletes used powdered Creatine. But there was little change after loading with Creatine Serum.

Creatine Serum came to the attention of authorities in New Zealand, who took action against the manufacturers. On the 14th July 2004, Muscle Marketing USA was fined $70,000 in the Auckland District Court for breaching the Fair Trading Act in relation to ATP Advantage Creatine Serum.

In sentencing, Judge Everitt said that Muscle Marketing’s claims about its product were so far from actual reality that it was a very bad case of a misleading statement. “The company was highly culpable. On a scale of 1-10 it was 8.”

The Commerce Commission investigated claims that Muscle Marketing USA was making false representations in promotional material and labelling regarding the quantity of Creatine in its ATP Advantage Creatine Serum product and the benefits that people would get from using it.

Fair Trading Director Deborah Battell said that in the Commission’s view, Muscle Marketing USA falsely represented that 5ml of its serum yielded the equivalent of 2500mg of Creatine.

“Tests conducted on the serum showed that 5mls of the product contained only around 11.5mg of Creatine. This means that on the basis of Muscle Marketing USA’s recommended daily dose of 5mls a day, athletes would not be able to obtain the benefits as represented.
