creatina liquida

[twins]

ciao a tutti. ultimamente ho sentito parlare dei miracolosi effetti delle creatina "liquida".
qualcuno l'ha provata?
Risultati?
Vale la differenza di prezzo? (costa oltre due volte quella monoidrata in polvere).
Grazie a tutti

se ne è già èarlato, prova a fare una ricerca sul forum...mi pare che in america la ditta che la produce abbia subito un processo...per il semplice fatto che la creatina non era stabile come promuovevano loro nelle loro pubblicità e degenrava in creatinina...cosa che succede anche alla creatina monoidrato (in polvere) se vien mantenuta per un detrerminato tempo in un liquido tipo acqua

Infatti....----> frode!


A study presented at the 2003 Experimental Biology Meeting today in San Diego, California comparing the effect of creatine monohydrate powder to "creatine serum" marketed by Muscle Marketing USA, in side-by-side, placebo controlled tests show that while creatine monohydrate supplementation as offered by Degussa under the Creapure_ brand increases creatine levels in muscles by about 30 percent, the Muscle Marketing USA creatine serum product is totally ineffective, equivalent in performance to the placebos.

Consumers should not be misled by the claim stated on MMUSA's creatine serum labels that it contains creatine equivalent to 2.5 g of creatine monohydrate. Accepted analyses by many reputed scientists show that MMUSA's product does not contain any significant amounts of creatine but a degradation product, creatinine, instead [1]. Another earlier study showed that creatine serum had no effect on plasma creatine levels [2].

Muscle biopsies on subjects taking creatine serum according to the instructions on the MMUSA label (1 serving a day for 5 days) showed no effect on muscle creatine. Even a higher dose of creatine serum intake (8 servings a day purportedly providing 20 grams/day of creatine monohydrate equivalent for 5 days - supplementing more than one complete bottle (1 1/3 bottles)) resulted in no significant effect on muscle creatine or ATP levels.

This study was designed and supervised by a leading and widely-respected authority in the field, Prof. Richard B. Kreider, of the Exercise & Sport Nutrition Lab at Baylor University, in collaboration with Dr. Darryn Willoughby at Texas Christian University and Dr. Mark Tarnopolsky at McMaster University in Ontario, Canada [3].

According to Dr. Kreider. "The best way to determine the potential efficacy of a creatine product is to measure the effect the supplement has on increasing muscle creatine stores. Creatine monohydrate supplementation resulted in a significant increase in muscle Creatine. In contrast, this study clearly indicates that low and high dose ATP Advantage Creatine Serum has no effect on muscle creatine or ATP levels, hence Creatine Serum is ineffective in enhancing performance."

Any claims that creatine serum produces the desired effects of creatine monohydrate are unfounded. No peer-review articles show that creatine serum in fact increases creatine levels in the blood or muscle. The scientific literature shows the opposite to be true [2,3].

As the market leader for powdered creatine under the Creapure brand, Degussa BioActives will not accept any scientifically false claims about creatine powder.

Meglio la buona, vecchia ed efficace creatina monoidrato!

La creatina liquida è un fake pazzesco. Non per nulla la commercializza la Muscle MARKETING ...ed è tutto un dire....

C'è dietro una grossa campagna di comunicazione, ma i risutati su chi l'ha provata sono certamente contraddittori...

Piuttosto molto meglio la creatina citrato Degussa.

Concordo...quando si comprano 12 pagine su Muscle and fitness per pubblicizzarla, già capisci che c'è qualcosa che non va.....

meglio un bel po di pollo in frigo, con gli stessi soldi te ne fai una scorta che ti dara risultati di gran lunga superiori
