Monohydrate is good.

ONly if you are non-responder or get bad stomach problems, switch to CEE.

Kre-Alkalyn is a scam.

Thanks, but I still think that my thread on which do you prefer out of the 3 and the two threads (Which Creatine is your favorite & which do you prefer Creatine and Kre-Alkalyn) that you posted are different...But thanks all the same...

For crying out loud, what more do you want

I use the cheapest monohydrate I can find.  I was not having any success until I started taking 10g a day.  Then it really worked.  great stuff! 

get the cheapest creatine monohydrate out there

CEE is by far the best. Super high bio availibility, no bloat, no loading... Cant go wrong.  Kre Alkalyn is way overated. Just make sure your CEE has citrulline malate, & you will notice the effects on the first dose. Stay away from Cellmass, Cem3 is not the real deal.

anything where the source is creapure.

I've used the Sci-fit Kre-Alklyn 3 different times now and each occassion its worked better for me than regular monohydrate. I remember reading that almost 25% of people who took the original mono back in the day would have problems with absorbing it. I must have been in that group because I was always stunned when I heard people talking about how awesome Phosphagen was when it first came out. Anyway its cheap and it seems to work so I'll probably stick with this. CEE also worked pretty well for me, but I don't like the idea of taking something that breaks down to ethanol on a daily basis....

I had the same results with the Sci-fit brand only. The other brands I've tried led to jackshit. The CEE didn't do anything for me either. Sci-fit was the only brand of any type of creatine/kre-alkylyn that gave me any results Smiley

I have been using Kre-alkyne (sp?) powder by Sci-fit.  It seems to work well, with out as much bloat.

The 5 types are monohydrate, Creatine ethyl ester HCL, TriCreatine Malate,Chreatine Alpha Ketoglutrate and Creatine Pyruvate.  I have used them all since 95' and haven't gotten nearly the results of this stuff.  Kre-alkyne is a scam.  You can have a paten on anything and that's their selling point.


I've tried mono, didn't notice much, tried CEE, again, didn't notice much.

 


creatine is creatine is creatine.

Agreed. I don't care for creatine but just go for the cheap stuff. Mono is easy to get cheap & micronized.

Creatine ethyl ester rapidly degrades to creatinine in stomach acid

Child R1 and Tallon MJ2

1Department of Life Sciences, Kingston University, Penrhyn Rd, Kingston-upon-Thames, United Kingdom. 2University of Northumbria, Sport Sciences, Northumbria University, Northumberland Building, Newcastle upon Tyne, United Kingdom, DrChild@CR-Technologies.net

Creatine ethyl ester (CEE) is a commercially available synthetic creatine that is now widely used in dietary supplements. It comprises of creatine with an ethyl group attached and this molecular configuration is reported to provide several advantages over creatine monohydrate (CM). The Medical Research Institute (CA, USA) claim that the CEE in their product (CE2) provides greater solubility in lipids, leading to improved absorption. Similarly San (San Corporation, CA, USA) claim that the CEE in their product (San CM2 Alpha) avoids the breakdown of creatine to creatinine in stomach acids. Ultimately it is claimed that CEE products provide greater absorption and efficacy than CM. To date, none of these claims have been evaluated by an independent, or university laboratory and no comparative data are available on CEE and CM.

This study assessed the availability of creatine from three commercial creatine products during degradation in acidic conditions similar to those that occur in the stomach. They comprised of two products containing CEE (San CM2 Alpha and CE2) and commercially available CM (Creapure?). An independent laboratory, using testing guidelines recommended by the United States Pharmacopeia (USP), performed the analysis. Each product was incubated in 900ml of pH 1 HCL at 37? 1oC and samples where drawn at 5, 30 and 120 minutes. Creatine availability was assessed by immediately assaying for free creatine, CEE and the creatine breakdown product creatinine, using HPLC (UV)

After 30 minutes incubation only 73% of the initial CEE present was available from CE2, while the amount of CEE available from San CM2 Alpha was even lower at only 62%. In contrast, more than 99% of the creatine remained available from the CM product. These reductions in CEE availability were accompanied by substantial creatinine formation, without the appearance of free creatine. After 120minutes incubation 72% of the CEE was available from CE2 with only 11% available from San CM2 Alpha, while more than 99% of the creatine remained available from CM.

CEE is claimed to provide several advantages over CM because of increased solubility and stability. In practice, the addition of the ethyl group to creatine actually reduces acid stability and accelerates its breakdown to creatinine. This substantially reduces creatine availability in its esterified form and as a consequence creatines such as San CM2 and CE2 are inferior to CM as a source of free creatine.

------------------------------------------------------------------

Kre-alkalyn? supplementation has no beneficial effect on creatine-to-creatinine conversion rates.

Tallon MJ1 and Child R2

1University of Northumbria, Sport Sciences, Northumbria University, Northumberland Building, Newcastle upon Tyne, United Kingdom, 2Department of Life Sciences, Kingston University, Penrhyn Rd, Kingston-upon-Thames, United Kingdom. DrTallon@CR-Technologies.net

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.
