I asked a guy at the place i buy supps but he said they didn't do much of any thing, but I read on the forums different. Any advice?
I am cutting at this time.

Guys what do u think of this post? It was posted by a pretty knowlegable guy on here Alan .
"Could Xtend replace Option 2 for preW (20-50g prot + 40-80g carb)? It depends on the nature & timing of what you had before that, but suffice it to say that the science on prot + carbs immediately preW is pretty damn solid for both sparing internal fuel reserves & inducing protein synthesis. Not to mention, if you scoot that same prot + carbs elsewhere, the partitioning of them might not be as optimal. And from another practical standpoint, are your goals such that a 400 kcal reduction wouldn't hurt? You'd have to answer that one for yourself.
Let's take a look at Xtend's fact sheet:
Quote:
Serving Size: 2 Scoops (11.5 grams)
Price of larger tub: $79.99 (price per serving $0.88)
Vitamin B6 (as Pyroxidine HCl) 10mg
Leucine 3.5g
Glutamine 2.5g
Isoleucine 1.75g
Valine 1.75g
Citrulline Malate 1g
Ingredients:
L-Leucine, L-Glutamine, L-Valine, L-Isoleucine, Citrulline Malate, Natural and Artificial Flavors, Potassium Citrate, Citric Acid, Acesulfame Potassium, Sucralose, Pyridoxine HCl, Red #40, Blue #1
Now let's take a look at Bioplex unflavored WPI:
Quote:
Serving size: 1.5 scoops (33g)
Price of 5lb tub: 54.98 (price per serving = $0.80)
Alanine 1.7g
Arginine 0.9g
Aspartic Acid 3.5g
Cysteine 0.6g
Glutamic Acid 6g
Glycine 0.7g
Histidine 0.6g
Isoleucine 2.5g
Leucine 3.8g
Lysine 3g
Methionine 0.6g
Phenylalanine 1g
Proline 1.9g
Serine 1.8g
Threonine 2.3g
Tryptophan 0.6g
Tyrosine 0.9g
Valine 1.8g
Ingredients:
Pure microfiltered whey protein isolate
I bolded what both products have in common.
WPI has more BCAA content than Xtend when the serving size per pricepoint is matched. I even gave Xtend a little slack; if I matched the price per serving size exactly, the WPI's BCAA content would beat out Xtend's even more.
To Xtend's credit, it has glutamine (2.5g), citrulline malate (1g), & vitamin b6, WPI has none. However, WPI has the rest of the essential & nonessential aminos, & other bioactive microfractions not present in Xtend.
If I were to be cynical about this, citrulline malate (CM) was found to be effective for increasing aerobic capacity. Anaerobic effects remain to be measured. Not only that, the most recent studies on CM are funded by the French manufacturer of it under the trade name Stimol. Ah, but this is a common confounder in research. How valuable is the 2.5g glutamine per serving in Xtend? For purposes of building new muscle, probably nil. For therapeutic effects on gastrointestinal health, that dose is probably too low. As for the B6, although it's an essential co-factor for glycogen phosphorylase and certain enzymes in the alanine-glucose cycle, it hasn't been observed in research to enhance athletic performance. So far, it's all speculation based on circumstantial bits & pieces. There's also the inclusion of artificial sweeteners & colors that I'm not crazy about, regardless of dose.
On the optimistic side of Xtend, you can always count on the powerful placebo effect. Even non-nutritive flavored drinks taken in during training encourage the motivation to drink more, & thus better preserve fluid balance in endurance exercise. You can capitalize on psycho****tic effect even further by adding sugar to your Xtend dose, since carbohydrate receptors in the mouth act upon central mechanisms that facilitate ergogenesis. Sure, you can take Xtend during training on top of the recommended intake I outlined at the start of this thread, but if your training bout is 60 minutes or less, the supp's actual effect beyond the preW shake you're already absorbing will be more psychologically based than anything. To be fair, I can see the product potentially benefitting those whose training bouts approach the 2 hr mark. But even then, there are questions to be raised about exercise type & cheaper alternatives to the supplement.Official Champion Performance Forum Rep

Not to hijack the thread, but I asked the guy at GNC if he knew of anywhere to obtain dextrose b/c shipping that stuff gets expensive. He said no and that he can't even get it on the internet b/c you can use the stuff to make bombs. I proceeded to lower my head and shake it back and forth at that point.
At least he knew it was a sugar. I asked 3 employees standing together at Vitamin Shoppe if they carried it or knew of anyone who did. First they told me they'd never heard of a supplement called dextrose (wtf!?!?!?) and then asked me who the manufacturer was.

[QUOTE=young_squatter]Well that guy is wrong, BCAA greatly help with recovery and help you pack on mass, well cutting there even more important, they will help you maintain and even gain lean mass well cutting. Here are a lot of articles to prove BCAA are very effective.
Young Squatter, Some guys recommend the simple sugar with the BCAA's. I know thats not a good practice while cutting, but if not cutting, is adding dextrose to bcaa's, glutamine, and creatine during a workout more for guys with extremely high volume or is it unnecessary or even a bad practice. Some say it aids in being more anabolic.

Exercise Promotes BCAA Catabolism: Effects of BCAA Supplementation on Skeletal Muscle during Exercise
Yoshiharu Shimomura, Taro Murakami, Naoya Nakai, Masaru Nagasaki and Robert A. Harris
Abstract
Branched-chain amino acids (BCAAs) are essential amino acids that can be oxidized in skeletal muscle. It is known that BCAA oxidation is promoted by exercise. The mechanism responsible for this phenomenon is attributed to activation of the branched-chain -keto acid dehydrogenase (BCKDH) complex, which catalyzes the second-step reaction of the BCAA catabolic pathway and is the rate-limiting enzyme in the pathway. This enzyme complex is regulated by a phosphorylation-dephosphorylation cycle. The BCKDH kinase is responsible for inactivation of the complex by phosphorylation, and the activity of the kinase is inversely correlated with the activity state of the BCKDH complex, which suggests that the kinase is the primary regulator of the complex. We found recently that administration of ligands for peroxisome proliferator-activated receptor- (PPAR) in rats caused activation of the hepatic BCKDH complex in association with a decrease in the kinase activity, which suggests that promotion of fatty acid oxidation upregulates the BCAA catabolism. Long-chain fatty acids are ligands for PPAR, and the fatty acid oxidation is promoted by several physiological conditions including exercise. These findings suggest that fatty acids may be one of the regulators of BCAA catabolism and that the BCAA requirement is increased by exercise. Furthermore, BCAA supplementation before and after exercise has beneficial effects for decreasing exercise-induced muscle damage and promoting muscle-protein synthesis; this suggests the possibility that BCAAs are a useful supplement in relation to exercise and sports.

Not a fan of it either or any type of postworkout shake. Once u try the diet you will realize there is no need for one

I can see where protein powders would be beneficial for in between meal protein supplementing.
I can say, I have tried workouts recently with and without the dextrose, bcaa, creatine, glutamine drink during and I can honestly say, I get through the workouts without dragging azz when I do have the drink.Last edited by Big Boi 1906; 05-11-2006 at 11:43 AM.
