Whey should only really be used post workout is because at any other time when it is taken by itself your body only uses about 30% of the amino acids. You see, whey gives your body such a quick flood of aminos that the body thinks it has more protein than it actually does and it sends the "excess" to the liver, where it is oxidized and used as energy.
Casein- Casein is the opposite of whey. It is an insoluble, slow-digesting, milk derived protein. Casein has been shown to be anti-catabolic in several studies but has no effect on increasing protein synthesis. So what is it good for: Casein gels in the stomach and is slow to digest.
In fact it takes casein at least 2.5 hours to digest and up to 4 in some cases. For that reason it is good at any meal other than post workout. Casein is an excellent choice especially right before bed since it gives you a slow stream of aminos over about 3-4 hours and prevents muscle breakdown. You need this slow stream of aminos since your body will be going 8 hours without any protein.

You should not eat any whey protein unless its right after working out!!

Sssh.
That is utter crap about not being able to take whey unless postworkout.
All proffesional bodybuilders drink whey ALL throughout the day
They start their breakfast off with whey,
Have whey pre and post workout
Have whey in the evening (casein)
And sometimes even more.
As a opinunated human, i go by what I see HAPPENING and not by other people's research. Research nowadays is so easily pulled off of a website created by somebody that doesn't know what he's talking about and providing incorrect "research" statements.
I go by results, visually proved, etc.
If i can see it, it's there (give or take TV etc, special effects/editting)
Therefor, i dont believe in the crap you just told us.
Kthnxbye

Is there a study to back up this information? No offensive by this.. Just wondering what your basis of saying this is.
Also.. Havent there been studies showing that the "Anabolic PWO Window" is basically bull****?Last edited by Lax891122; 12-06-2007 at 12:43 PM.

Here's a study that highlights pre and post-WO supplementation is better than only using at other times during the day.
My opinion from everything I've read is to have a whey isolate shake pre-WO with carbs (so that the body doesn't have to tap into it's own amino acid pool, instead using the whey, once the stored/ingested glycogen is used up).
Effects of supplement timing and resistance exercise on skeletal muscle hypertrophy.Cribb PJ, Hayes A.
Exercise Metabolism Unit, Center for Ageing, Rehabilitation, Exercise and Sport; and the School of Biomedical Sciences, Victoria University, Melbourne, Victoria, Australia.
PURPOSE: Some studies report greater muscle hypertrophy during resistance exercise (RE) training from supplement timing (i.e., the strategic consumption of protein and carbohydrate before and/or after each workout). However, no studies have examined whether this strategy provides greater muscle hypertrophy or strength development compared with supplementation at other times during the day. The purpose of this study was to examine the effects of supplement timing compared with supplementation in the hours not close to the workout on muscle-fiber hypertrophy, strength, and body composition during a 10-wk RE program. METHODS: In a single-blind, randomized protocol, resistance-trained males were matched for strength and placed into one of two groups; the PRE-POST group consumed a supplement (1 g x kg(-1) body weight) containing protein/creatine/glucose immediately before and after RE. The MOR-EVE group consumed the same dose of the same supplement in the morning and late evening. All assessments were completed the week before and after 10 wk of structured, supervised RE training. Assessments included strength (1RM, three exercises), body composition (DEXA), and vastus lateralis muscle biopsies for determination of muscle fiber type (I, IIa, IIx), cross-sectional area (CSA), contractile protein, creatine (Cr), and glycogen content. RESULTS: PRE-POST demonstrated a greater (P < 0.05) increase in lean body mass and 1RM strength in two of three assessments. The changes in body composition were supported by a greater (P < 0.05) increase in CSA of the type II fibers and contractile protein content. PRE-POST supplementation also resulted in higher muscle Cr and glycogen values after the training program (P < 0.05). CONCLUSION: Supplement timing represents a simple but effective strategy that enhances the adaptations desired from RE-training.RIP Dad

After some futher looking on PubMed - I found the study used to basically create Xtreme Forumlation's Vendetta supplement.
This indicates EAA's are more important than whey protein. (A follow-up study showed no real difference in blood amino acid concentrations/uptake when comparing WHEY taking pre and post-WO.)

Timing of amino acid-carbohydrate ingestion alters anabolic response of muscle to resistance exercise.Tipton KD, Rasmussen BB, Miller SL, Wolf SE, Owens-Stovall SK, Petrini BE, Wolfe RR.
Department of Surgery, University of Texas Medical Branch, Galveston, Texas 77550, USA. ktipton@utmb.edu
The present study was designed to determine whether consumption of an oral essential amino acid-carbohydrate supplement (EAC) before exercise results in a greater anabolic response than supplementation after resistance exercise. Six healthy human subjects participated in two trials in random order, PRE (EAC consumed immediately before exercise), and POST (EAC consumed immediately after exercise). A primed, continuous infusion of L-[ring-(2)H(5)]phenylalanine, femoral arteriovenous catheterization, and muscle biopsies from the vastus lateralis were used to determine phenylalanine concentrations, enrichments, and net uptake across the leg. Blood and muscle phenylalanine concentrations were increased by approximately 130% after drink consumption in both trials. Amino acid delivery to the leg was increased during exercise and remained elevated for the 2 h after exercise in both trials. Delivery of amino acids (amino acid concentration times blood flow) was significantly greater in PRE than in POST during the exercise bout and in the 1st h after exercise (P < 0.05). Total net phenylalanine uptake across the leg was greater (P = 0.0002) during PRE (209 +/- 42 mg) than during POST (81 +/- 19). Phenylalanine disappearance rate, an indicator of muscle protein synthesis from blood amino acids, increased after EAC consumption in both trials. These results indicate that the response of net muscle protein synthesis to consumption of an EAC solution immediately before resistance exercise is greater than that when the solution is consumed after exercise, primarily because of an increase in muscle protein synthesis as a result of increased delivery of amino acids to the leg.

I should say I remember reading a direct comparison of protein taken pre and post-workout and the effect on lean body mass.
The prior study doesn't look at that aspect directly.
I can't find it though.RIP Dad
