Os Diferentes Tipos De Creatinas, Com Algumas Dosagens Na 2ºpag.

[hufus 10]

parabens cara, faz tempo que nao se ve um topico realmente util por aqui, e quando aparece nos temos que agradecer boa cara.

Só opinando rapidamente sobre algo, não acho que de pra comparar uma creatina com a outra usando estas em blend (como voce disse que ia experimentar crea hcl no neurocore); PW tem muita coisa que pode interferir no mesmo sentido da creatina, então é complicado isolar apenas as creatinas e atribuir algo a elas. Por ex: voce pode usar Clout e Neurocore, ter ganho mais força com Neurocore pelo gás extra dos estimulantes, mas na verdade a "orotine" seria mais eficaz para voce se tivesse utilizado isoladamente em comparação com a crea hcl. Enfim, só achei bacana comentar isso

Corretissimo Craw!!! Por essas e por outras eu acho besteira aqueles pw q vem com trocentas creatinas vide"noxplod e shotgun e varios outros". Porem percebo uma tendencia nos novos pw de reducirem o numero de substancias no blend e aumentar as q cotinuaram a fazer parte do blend, vide novo nanovapor em comparação ao antigo.

Contribuindo também, sobre a CEE (Creatine Ethyl Ester):

The effects of creatine ethyl ester supplementation combined with heavy resistance training on body composition, muscle performance, and serum and muscle creatine levels.

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.

Creatine ethyl ester rapidly degrades to creatinine in stomach acid

Child R1 and Tallon MJ2

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.

Conclusão para que não leu ou não entendeu, ela é uma bosta comparada com a Mono.

Excelente contribuição galera!

Podem colocar como fixo, né não?

Alguém aí sabe se algum desses tipos de creatina não sofre com aquele efeito negativo de combinação com a cafeína?

[MadLuke 2]

E a Con-cret? tem outro nome ae e eu não percebi? To vacilando? Essa é uma que eu tenho vontade de experimentar alem da mono

[Galeno 35]

Con-cret é cloridrato de creatina(creatine hcl)!

Creio eu q não vai interferir em muita coisa a cafeina, pode ate ter alguma perda mais nada q vá fazer vc "jogar dinheiro fora".

[jkbi83 1]

Eu tb acredito q não interfira tanto assim, Se vc responde bem a creatina nao será a cafeína q fará vc perder ao ponto de não valer a pena...

Até a grande maioria do pré-treinos tem cafeína combinada com algum tipo de creatina, entre outros componentes!

Agora segundo um estudo aí a apartir de 300mg de cafeína já prejudica o efeito da creatina, o quanto prejudica de forma prática já é uma outra questão mais complicada q deve variar bastante pra cada pessoa...

O assunto é meio polêmico, tipo mamilos! kkkk

Queria saber em que pé que andam os estudos mais recentes e se existe alguma forma de creatina em que esses efeitos antagônicos não sejam observados.
