CEE: not worth it.
Kre-Alk: WORTH IT
This new CEE claims there is no bloat compared to regular monohydrate. Is there any scietific articles that can back this up? I plan on takin it with var, and would love no water retention
The only thing I didnt like about CEE was the taste. Do yourself a favor and cap it up or buy it already in capsules.

Non-enzymatic cyclization of creatine ethyl ester to creatinine.

Abstract
Creatine ethyl ester was incubated at 37 degrees C in both water and phosphate-buffered saline and the diagnostic methylene resonances in the (1)H NMR spectrum were used to identify the resultant products. It was found that mild aqueous conditions result in the cyclization of creatine ethyl ester to provide inactive creatinine as the exclusive product, and this transformation becomes nearly instantaneous as the pH approaches 7.4. This study demonstrates that mild non-enzymatic conditions are sufficient for the cyclization of creatine ethyl ester into creatinine, and together with previous results obtained under enzymatic conditions suggests that there are no physiological conditions that would result in the production of creatine. It is concluded that creatine ethyl ester is a pronutrient for creatinine rather than creatine under all physiological conditions encountered during transit through the various tissues, thus no ergogenic effect is to be expected from supplementation.

Abstract
ABSTRACT: Numerous creatine formulations have been developed primarily to maximize creatine absorption. Creatine ethyl ester is alleged to increase creatine bio-availability. This study examined how a seven-week supplementation regimen combined with resistance training affected body composition, muscle mass, muscle strength and power, serum and muscle creatine levels, and serum creatinine levels in 30 non-resistance-trained males. In a double-blind manner, participants were randomly assigned to a maltodextrose placebo (PLA), creatine monohydrate (CRT), or creatine ethyl ester (CEE) group. The supplements were orally ingested at a dose of 0.30 g/kg fat-free body mass (approximately 20 g/day) for five days followed by ingestion at 0.075 g/kg fat free mass (approximately 5 g/day) for 42 days. Results showed significantly higher serum creatine concentrations in PLA (p = 0.007) and CRT (p = 0.005) compared to CEE. Serum creatinine was greater in CEE compared to the PLA (p = 0.001) and CRT (p = 0.001) and increased at days 6, 27, and 48. Total muscle creatine content was significantly higher in CRT (p = 0.026) and CEE (p = 0.041) compared to PLA, with no differences between CRT and CEE. Significant changes over time were observed for body composition, body water, muscle strength and power variables, but no significant differences were observed between groups. In conclusion, when compared to creatine monohydrate, creatine ethyl ester was not as effective at increasing serum and muscle creatine levels or in improving body composition, muscle mass, strength, and power. Therefore, the improvements in these variables can most likely be attributed to the training protocol itself, rather than the supplementation regimen.
yea i actually heard about kre-alk not too long ago. Whats the main difference? Its a creatine but is their just some extra added goodness? or whats the deal
Kre-alkalyn supplementation has no beneficial effect on creatine-to-creatinine conversion rates.

All American Pharmaceutical and Natural Foods Corp. (Billings, MT, USA) claim that Kre-alkalyn? (KA) a ?Buffered? creatine, is 100% stable in stomach acid and does not convert to creatinine. In contrast, they also claim that creatine monohydrate (CM) is highly pH labile with more than 90% of the creatine converting to the degradation product creatinine in stomach acids. To date, no independent or university laboratory has evaluated the stability of KA in stomach acids, assessed its possible conversion to creatinine, or made direct comparisons of acid stability with CM.
This study examined whether KA supplementation reduced the rate of creatine conversion to creatinine, relative to commercially available CM (Creapure?). Creatine products were analyzed by an independent commercial laboratory using testing guidelines recommended by the United States Pharmacopeia (USP). Each product was incubated in 900ml of pH 1 HCL at 37? 1oC and samples where drawn at 5, 30 and 120 minutes and immediately analyzed by HPLC (UV) for creatine and creatinine.
In contrast to the claims of All American Pharmaceutical and Natural Foods Corp., the rate of creatinine formation from CM was found to be less than 1% of the initial dose, demonstrating that CM is extremely stable under acidic conditions that replicate those of the stomach. This study also showed that KA supplementation actually resulted in 35% greater conversion of creatine to creatinine than CM. In conclusion the conversion of creatine to creatinine is not a limitation in the delivery of creatine from CM and KA is less stable than CM in the acid conditions of the stomach.
I think it's a scam. At least the marketing is. Kre-Alkalyn is 99% creatine monohydrate with a buffer added, which doesn't do what the sellers claim anyway (see study). Why do users claim they bloat less with it? Because they're taking less of it.

never tried it, however, I met the creator a few years ago at the arnold. this "scientist" (visit the webiste) has no credentials, no background in science. im sorry I hate dogging people but the supp industry is so fucked anyway. just be honest and tell people you were playing around with some vitamins in your moms basement, dont put on a fucking lab coat and call yourself a scientist.
Relatively recent research shows it appears it can't do anything - see the studies.
Then again Massive G and some other bros have said it's the most potent shit they ever tried that was "natural" so who knows. I mean we all are subject to the placebo effect. I thought I noticed a little something from it too.
Creatine Mono is proven effective, unlike all the other forms. You don't want bloat (which I think is imaginary in many/most cases)? Just take less. You don't need many grams to saturate muscle creatine stores.

Yes, I agree with KS
I'd recommend just staying with monohydrate, unless it causes GI distress/problems for those who are sensitive to it, in which case i'd probably try the CEE....or just take less monohydrate per serving.
Once saturation is accomplished, most folks can usually cut back down to very low maintenance intakes, so monohydrate should be fine for that
