Study: ‘creatine ethyl ester doesn’t work’
saw this on this link and looks interesting to debate
Study: ‘ doesn’t work’
Ordinary creatine works better than , according to a study carried out at Baylor University in Texas. They say that the creatine analogue is of little use to beginner-level athletes. We at Ergo-log have our reservations about the study, but let the facts speak for themselves. That way you can judge for yourself.
[structural formula shown below] is an ethyl analogue of creatine. The ethyl group makes the molecule less soluble in water. According to the manufacturers of supplements containing creatine ethyl ester, this characteristic
means that the analogue enters muscle cells more easily. That’s why the substance, if taken thirty minutes to an hour before a weight training session, should work better than creatine. This is also the experience of many users.
A study published way back in 1955 showed that, in an acid environment, creatine ethyl ester is converted into the far less active creatinine. [J Amer Chem Soc. 1955;77:178–180.] This was recently confirmed in a British test-tube study – although the results weren’t published, they were presented at a congress on sports nutrition in 2007. [Link] But there were no human studies in
which test subjects had taken creatine ethyl ester.
The researchers did an experiment with thirty young men who had not trained before. One group were given a placebo and did weight training. Another group trained also and took ordinary creatine, and yet another group trained and took the creatine ethyl ester produced by Labrada. During the first week the test subjects took twenty grams daily of creatine or the ethyl analogue. For six weeks after that they took a daily five grams of the supplement they were on. The supplements were taken in the morning, and the subjects were allowed to train whenever they wanted. So no, they didn’t use the supplements as they should be used.
The creatine ethyl ester [CEE] had hardly any effect. The quantity of creatine in the muscles increased by a small amount, but the ordinary creatine [CRT] worked better.
The creatine ethyl ester did lead to a considerable increase in the amount of creatinine in the test subjects' blood.
After seven weeks of taking the supplement, the creatine users had made the same amount of progress as the creatine ethyl ester users and the placebo group. In terms of body composition and the development of muscle power, all three groups had made the same amount of progress.
"It can be concluded that a large portion of the creatine ethyl ester was being degraded within the GI tract after ingestion", the researchers conclude. "Furthermore, it appears that the skeletal muscle uptake of creatine ethyl ester uptake was not significant enough to increase skeletal muscle creatine levels without significant degradation to creatinine occurring".
That is the researchers’ conclusion. But creatine ethyl ester didn‘t really have a fair chance in this study.

I would not wipe my ass with anything that is related to that piss-poor site, ergo-log. Although, I do agree that Mono is far superior to CEE; however, you guys need to check into Trinitine. WoW!
Good article, though, Nunes!

"The supplements were taken in the morning, and the subjects were allowed to train whenever they wanted. So no, they didn’t use the supplements as they should be used."
That says enough for me to not take this study seriously. It wasn't strict enough.
First time I took ethyl ester I thought it was one of the best supplements ever. I got big pumps from it. Then after a few weeks no more pumps and no more results. Now i stick with monohydrate and it does the job all the time.. not just for short periods of time.

Blah its no big deal. Duplicate posts can be a pain, usually when they are duplicate posts of the same questions that have been answered 10 thousand times, but you were just trying to bring some research to light and help some members. Thanks for posting

I dont see any harm done here.... its not like its a double post or repost of the same threat... that study just come out the same day it was posted there with new information, plus anyone who missed the previous post will benefit from this thread, thanks for posting this nunes!
