בתהליכיי ה Cell Mass (קריאטין)

[Guy_Malka]

לפי מה שהבנתי אני צריך לעשות ההמסה של חמישה ימים, לישתות את הקריאטין כול שלוש שעות... ואז להתחיל רגיל ליפניי אימון ואחריי אימון...

האם זה נכון?... או שיש או דרכים?

[Danzig]

שום העמסה שום נעליים, 5 לפני אימון 5 אחרי, ביום ללא אימון רק 5.

עריכה: לא שמתי לב שאתה מדבר על סלמס, בסלמס יש העמסה בכלל?

[gil-Nissim]

קריאטין רגיל, או סל מס ?.

[Guy_Malka]

סל מס חברים סל מס... אני יודע שברגיל ואחרים זה בלי העמסה או עם העמסה, עזבו את זה עכשיו...

סל מס רק סל מס האם מישהו שכח מה זה?

תקח רק ליפני האימון, יותר עדיף האחרי האימון..
סקופ 1... ביום.

אין עמסה בסל מס, זה קריאטין "אתיל אסטר"..

[Guy_Malka]

Afformative... תודה גבר...

איפה הוכח ? ..

הביא מחקר

למרות שגם אני,הרגשתי יותר את המנו מאשר את הנוז וכו'.

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 37º +/- 1ºC and samples where drawn at 5, 30 and 120 minutes and immediately analyzed by 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 120 minutes 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.

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 37º +/- 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.

מחר אני כבר יקרא את הכל.. תודה..
בכל מקרה, זה רק מחקר אחד... בישביל להוכיח את זה צריך עוד כמה מחקרים..

למרות שגם אני הרגשתי יותר את הטהור,מהאתיל אסטר..

אני מעדיף TCM או DiCm
מורגש מורגש, בעיקר עם ארגנין וקפרין

יאאמיי!!!!!
