pues no afecta al sueño la l-tirosina xD
y yo sigo durmiendo igual con todos los suples q estoy metiendo
Asegúrate que en el PWO haya un ratio de 2:1 a favor de los CHO sobre la proteína.
Unos 80 gramos de CHO y 40 gramos de proteína para una persona de 80 kg de peso estaría bien.
Por cierto, repasando los FAQ's y tal, veo que en definición en PeriWO pone no más de medio litro de agua. Viendo que la suplementación por monohidrato de creatina puede inducir a la deshidratación... seguro que hay que llevarse tanta poca agua? Me suelo beber 1'5L en entreno si tiro de peso (aparte del calor del gimnasio) + lo que beba a lo largo del día (me auto-obligué hace tiempo a ingerir más agua).
En definición y con los suplementos puestos en anterioridad (ALCAR, Creatina, L-Tyrosine, pastillas de cafeina, citrato de magnesio, multivitamínico y omega 3) hay que beber mucha agua, o estoy haciendo el panoli y no importa? Vamos, en volumen sí que he visto que hay que aumentar (aunque no sé si será verdad xD) la cantidad de agua bebida al día (algunos ponen más de 2L al día). Lo que no sé si en definición hay que bajarla, igualarla, subirla...
Para definición tb, el monitor del gym recomienda beber al menos 2 litros de agua fuera de las comidas...
yo creo que eso de beber menos etc pa definir es mierda xD, que no vamos a competir ni nada, bebed todo el agua que querais coño.
yo mas bien creo que el agua es NECESARIA, y a no ser que vayas a competir y necesites "secar" para salir a enseñar (me contaron anecdotas de alguno metiendose en el coche en verano con la calefaccion y bufanda xD) , para la vida diaria pues bebe el agua que necesites xD
Eisen, ¿Qué te parece esta creatina?
Si le dieras el visto bueno, la añadiría a lo que tengo, y así me ahorraba los gastos de envío!
300gr 12e menuda astillada.
En MP la puedes encontrar mucho mas barato, de Creapure igual, acuerdate de utilizar el price matcher con la web de www.bulkpowders.co.uk
Ajjjj, lástima, a ver qué cojo para llegar a los 60 € y ahorrarme los gastos de envío! Gracias por tu opinión, Maranello 
EDIT: Lo del price matcher, es del rollo... que en http://www.bulkpowders.co.uk/ hay cosicas más baratas, entonces en MP las sacas por ese precio?! Aunque los productos que me han salido, no he tenido la suerte de que estuvieran más baratos 
Yo no se si la web se la esta haciendo 0z4m4 o que, pero son un poco inutiles para reparar un error que les hace perder mucho dinero al dia xD
A un amigo le contestaron que antes de ayer, al final del dia, estaria operativo. A Akklaim y a mi nos mandaron un email automatico que no tenia nada que ver con nuestra pregunta xDDD
Buenas gente llevo 3 semanas haciendo cardio quiero bajar unos 5-6 kilos y he leido algo sobre L-carnitina que ayuda a sudar más y a perder más liquidos. Sobre que precio cuesta ? hay algún equivalente a dicho producto que se pueda comprar en una farmácia ?
grácias, un saludo.
Ei Angelo!
Pues yo ahora mismo estoy usando L-Carnitina con Cola de caballo de la marca Active Nutrition, y el bote de 120 caps. en tienda me costo 22€. Yo hace 2 semanas que lo estoy usando, ya te contare como va xD

Published: 19 May 2010 Abstract (provisional)
Background
Beta-Alanine (BA) has been shown to improve performance during cycling. This study was the first to examine the effects of BA supplementation on the onset of blood lactate accumulation (OBLA) during incremental treadmill running.
Methods
Seventeen recreationally-active men (mean +/- SE 24.9 +/-4.7 yrs, 180.6 +/-8.9 cm, 79.25 +/-9.0 kg) participated in this randomized, double-blind, placebo-controlled pre/post test 2-treatment experimental design. Subjects participated in two incremental treadmill tests before and after 28 days of supplementation with either BA(6.0 g.d-1)(BA, n=8) or an equivalent dose of Maltodextrin as the Placebo (PL, n=9). Heart rate, percent heart rate maximum (%HRmax), %VO2max@OBLA (4.0 mmol.L-1 blood lactate concentration) and VO2max (L.min-1) were determined for each treadmill test. Friedman test was used to determine within group differences; and Mann-Whitney was used to determine between group differences for pre and post values (p<0.05).
Results
The BA group experienced a significant rightward shift in HR@OBLA beats.min-1 (p<0.01) pre/post (161.6 +/-19.2 to 173.6 +/-9.9) but remained unchanged in the PL group (166.8 +/-15.8 to 169.6 +/-16.1). The %HRmax@OBLA increased (p <0.05) pre/post in the BA group (83.0% +/-9.7 to 88.6% +/-3.7) versus no change in the PL group (86.3% +/-4.8 to 87.9% +/-7.2). The %VO2max@OBLA increased (p<0.05) in the BA group pre/post (69.1+/-11.0 to 75.6+/-10.7) but remained unchanged in the PL group (73.3+/-7.3 to 74.3 +/-7.3). VO2max (L.min-1 ) decreased (p<0.01) in the BA group pre/post (4.57 +/-0.8 to 4.31 +/-0.8) versus no change in the PL group (4.04 +/-0.7 to 4.18 +/-0.8). Body mass kg increased (p < 0.05) in the BA group pre/post (77.9 +/- 9.0 to 78.3 +/- 9.3) while the PL group was unchanged (80.6 +/- 9.1 to 80.4 +/- 9.0).
Conclusions
BA supplementation for 28 days enhanced sub-maximal endurance performance by delaying OBLA. However, BA supplemented individuals had a reduced aerobic capacity as evidenced by the decrease in VO2max values post supplementation.

Pharmacological sodium nitrate supplementation has been reported to reduce the O2 cost of submaximal exercise in humans. [B]In this study, we hypothesized that dietary supplementation with inorganic nitrate in the form of beetroot juice (BR) would reduce the O2 cost of submaximal exercise and enhance the tolerance to high-intensity exercise[/B]In a double-blind, placebo (PL)-controlled, crossover study, eight men (aged 19–38 yr) consumed 500 ml/day of either BR (containing 11.2 ± 0.6 mM of nitrate) or blackcurrant cordial (as a PL, with negligible nitrate content) for 6 consecutive days and completed a series of "step" moderate-intensity and severe-intensity exercise tests on the last 3 days. On [I]days 4–6[/I], plasma nitrite concentration was significantly greater following dietary nitrate supplementation compared with PL (BR: 273 ± 44 vs. PL: 140 ± 50 nM; [I]P[/I] < 0.05), and systolic blood pressure was significantly reduced (BR: 124 ± 2 vs. PL: 132 ± 5 mmHg; [I]P[/I] < 0.01). [B]During moderate exercise, nitrate supplementation reduced muscle fractional O2 extraction[/B](as estimated using near-infrared spectroscopy). The gain of the increase in pulmonary O2 uptake following the onset of moderate exercise was reduced by 19% in the BR condition (BR: 8.6 ± 0.7 vs. PL: 10.8 ± 1.6 ml·min–1·W–1; [I]P[/I] < 0.05). [B]During severe exercise, the O2 uptake slow component was reduced[/B](BR: 0.57 ± 0.20 vs. PL: 0.74 ± 0.24 l/min; [I]P[/I] < 0.05), [COLOR=DarkOrange][B]and the time-to-exhaustion was extended[/B] (BR: 675 ± 203 vs. PL: 583 ± 145 s; [I]P[/I] < 0.05). The reduced O2 cost of exercise following increased dietary nitrate intake has important implications for our understanding of the factors that regulate mitochondrial respiration and muscle contractile energetics in humans.Free Radic Biol Med. 2001 Dec 1;31(11):1388-95.
The stomach as a bioreactor: dietary lipid peroxidation in the gastric fluid and the effects of plant-derived antioxidants.

Atherosclerosis may result partly from processes that occur following food consumption and that involve oxidized lipids in chylomicrons. We investigated reactions that could occur in the acidic pH of the stomach and accelerate the generation of lipid hydroperoxides and co-oxidation of dietary constituents. The ability of dietary polyphenols to invert catalysis from pro-oxidation to antioxidation was examined. The acidic pH of gastric fluid amplified lipid peroxidation catalyzed by metmyoglobin or iron ions. Metmyoglobin catalyzed peroxidation of edible oil, resulting in 8-fold increase of hydroperoxide concentration. The incubation of heated muscle tissue in simulated gastric fluid for 2 h enhanced hydroperoxides accumulation by 6-fold to 1200 microM. In the presence of catechin or red wine polyphenols, metmyoglobin catalyzed the breakdown of hydroperoxides to zero, totally preventing lipid peroxidation and beta-carotene cooxidation.We suggest that human gastric fluid may be an excellent medium for enhancing the oxidation of lipids and other dietary constituents. The results indicate the potentially harmful effects of oxidized fats intake in the presence of endogenous catalysts found in foods, and the major benefit of including in the meal plant dietary antioxidants.

Current evidence supports a contribution of polyphenols to the prevention of cardiovascular disease, but their mechanisms of action are not understood. We investigated the impact of red wine polyphenols on postprandial cytotoxic lipid peroxidation products (MDA) levels in humans. In a randomized, crossover study, the effect of red wine polyphenols on postprandial levels of plasma and urine MDA was investigated. Three meals of 250 g turkey cutlets supplemented by water (A); soaked in red wine after heating plus 200 ml of red wine (
; or soaked in red wine prior to heating plus 200 ml of red wine (C) were administered to 10 healthy volunteers. Subject baseline plasma levels of MDA were 50 ± 20 nM. After a meal of turkey meat cutlets, plasma MDA levels increased by 160 nM (P<0.0001); after ( there was a 75% reduction in the absorption of MDA (P<0.0001). However, after (C), the elevation of plasma MDA was completely prevented (P<0.0001). Similar results were obtained for MDA accumulation in urine. Our study suggests that red wine polyphenols exert a beneficial effect by the novel new function, absorption inhibition of the lipotoxin MDA. These findings explain the potentially harmful effects of oxidized fats found in foods and the important benefit of dietary polyphenols in the meal.—Gorelik, S., Ligumsky, M., Kohen, R., Kanner, J.

Do carbohydrates increase the magnitude of the inflammatory response?
Creator: Depner, Chris Michael
Description: Inflammation is the body's response to tissue damage and infection and is correlated with several chronic diseases like type II diabetes. Cytokines are cell signaling proteins with multiple functions including control of inflammation. Cytokines are influenced by several factors such as carbohydrate intake and exercise. Thus, carbohydrate intake and exercise can influence inflammation. Purpose: To determine the influence of high carbohydrate intake on the inflammatory response to exercise that induces muscle damage and inflammation. Methods: The study was a cross-over design. Each subject completed a high carbohydrate condition and a high fat and protein condition. Each condition consisted of 6 sets of 10 maximal high-force eccentric contractions of the elbow flexors and extensors. The exercise was followed by a controlled diet for the first 8 hours post-exercise based on the condition. The cytokines interleukin-6 (IL-6) and interleukin-1β (IL-β ) were measured as indicators of local inflammation. C-reactive protein (CRP) was measured as an indicator of systemic inflammation. Creatine-kinase (CK), muscle soreness, upper arm circumference, and strength loss were measured as indicators of muscle damage. Blood glucose and insulin were measured to identify differences between diets in the conditions. Results: Insulin was significantly increased in the high carbohydrate condition compared to the high fat and protein condition at 1.5, 4, and 8 hours post-exercise. Perceived soreness was elevated at all time points post-exercise in both conditions and was significantly elevated in the high carbohydrate condition compared to the high fat and protein condition. There was a main effect trend for IL-6 to be greater in the high carbohydrate condition compared to the high fat and protein condition. Il-1β was significantly increased 24 hours post-exercise in the high carbohydrate condition compared to the high fat and protein condition. Conclusion: Elevated carbohydrate intake post-exercise augmented the local inflammatory response to the exercise observed by elevated IL-1β and IL-6. The augmented inflammatory response contributed to greater perceived muscle soreness post-exercise. Further research is required to investigate this mechanism further to provide better prevention and treatment methods for chronic diseases related to inflammation.

Comparison of pre-workout nitric oxide stimulating dietary supplements on skeletal muscle oxygen saturation, blood nitrate/nitrite, lipid peroxidation, and upper body exercise performance in resistance trained men.
Bloomer RJ, Farney TM, Trepanowski JF, McCarthy CG, Canale RE, Schilling BK.
Abstract
ABSTRACT: BACKGROUND: We compared Glycine Propionyl-L-Carnitine (GlycoCarn(R)) and three different pre-workout nutritional supplements on measures of skeletal muscle oxygen saturation (StO2), blood nitrate/nitrite (NOx), lactate (HLa), malondialdehyde (MDA), and exercise performance in men. Methods: Using a randomized, double-blind, cross-over design, 19 resistance trained men performed tests of muscular power (bench press throws) and endurance (10 sets of bench press to muscular failure). A placebo, GlycoCarn(R), or one of three dietary supplements (SUPP1, SUPP2, SUPP3) was consumed prior to exercise, with one week separating conditions. Blood was collected before receiving the condition and immediately after exercise. StO2 was measured during the endurance test using Near Infrared Spectroscopy. Heart rate (HR) and rating of perceived exertion (RPE) were determined at the end of each set. Results: A condition effect was noted for StO2 at the start of exercise (p=0.02), with GlycoCarn(R) higher than SUPP2. A condition effect was also noted for StO2 at the end of exercise (p=0.003), with SUPP1 lower than all other conditions. No statistically significant interaction, condition, or time effects were noted for NOx or MDA (p>0.05); however, MDA decreased 13.7% with GlycoCarn(R) and increased in all other conditions. Only a time effect was noted for HLa (p<0.0001), with values increasing from pre- to post-exercise. No effects were noted for HR, RPE, or for any exercise performance variables (p>0.05); however, GlycoCarn(R) resulted in a statistically insignificant greater total volume load compared to the placebo (3.3%), SUPP1 (4.2%), SUPP2 (2.5%), and SUPP3 (4.6%). Conclusion: None of the products tested resulted in favorable changes in our chosen outcome measures, with the exception of GlycoCarn(R) in terms of higher StO2 at the start of exercise. GlycoCarn(R) resulted in a 13.7% decrease in MDA from pre- to post-exercise and yielded a non-significant but greater total volume load compared to all other conditions. These data indicate that 1) a single ingredient (GlycoCarn(R)) can provide similar practical benefit than finished products containing multiple ingredients, and 2) while we do not have data in relation to post-exercise recovery parameters, the tested products are ineffective in terms of increasing blood flow and improving acute upper body exercise performance.

En tu gimnasio... aunque muestres el estudio [muy interesantes todos, por cierto], simplemente te dirán que se lo ha inventado el tio y ya está.
Las personas 'fieles' a cualquier cosa, lo suelen ser siempre. Por lo general no cambian de parecer nunca, ya le puedes mostrar mil estudios que para sus adentros dirán aquello de 'A palabras necias, oidos sordos'.
PD: A ver si por un casual, les diese a MP por arreglar la puta web [menuda panda de ineptos] que tengo pensado un pedidillo... que sería la excusa perfecta para probar la MP Smooth.
PD2: Es lo mejor xd.
