The following study compaing whey isolate and pea protein may give you another viable option while saving money.

Abstract

BACKGROUND: The effects of protein supplementation on muscle thickness and strength seem largely dependent on its composition. The current study aimed at comparing the impact of an oral supplementation with vegetable Pea protein (NUTRALYS®) vs. Whey protein and Placebo on biceps brachii muscle thickness and strength after a 12-week resistance training program.

METHODS: One hundred and sixty one males, aged 18 to 35 years were enrolled in the study and underwent 12 weeks of resistance training on upper limb muscles. According to randomization, they were included in the Pea protein (n = 53), Whey protein (n = 54) or Placebo (n = 54) group. All had to take 25 g of the proteins or placebo twice a day during the 12-week training period. Tests were performed on biceps muscles at inclusion (D0), mid (D42) and post training (D84). Muscle thickness was evaluated using ultrasonography, and strength was measured on an isokinetic dynamometer.

RESULTS: Results showed a significant time effect for biceps brachii muscle thickness (P < 0.0001). Thickness increased from 24.9 ± 3.8 mm to 26.9 ± 4.1 mm and 27.3 ± 4.4 mm at D0, D42 and D84, respectively, with only a trend toward significant differences between groups (P = 0.09). Performing a sensitivity study on the weakest participants (with regards to strength at inclusion), thickness increases were significantly different between groups (+20.2 ± 12.3%, +15.6 ± 13.5% and +8.6 ± 7.3% for Pea, Whey and Placebo, respectively; P < 0.05). Increases in thickness were significantly greater in the Pea group as compared to Placebo whereas there was no difference between Whey and the two other conditions. Muscle strength also increased with time with no statistical difference between groups.

CONCLUSIONS: In addition to an appropriate training, the supplementation with pea protein promoted a greater increase of muscle thickness as compared to Placebo and especially for people starting or returning to a muscular strengthening. Since no difference was obtained between the two protein groups, vegetable pea proteins could be used as an alternative to Whey-based dietary products.

The difference in net growth could be due to the digestive variances that existed in the Whey group. Whey protein tends to trigger lactose intolerance in those having the predisposition and can lead to malabsorption. Considering it is simply labeled as Whey Protein and not an iso-whey supplement then I can only assume that there was a large amount of that specific group suffering from G.I discomfort/malabsoprtion.

EDIT: I'm assuming it was the higher probability for malabsorption of the whey supplement to occur due to the triggering of lactose intolerance. The pea protein was more biologically friendly in that there isn't a specific enzyme that varys greatly between the population (aforementioned lactase enzyme's activity) and allows for a effective digestion and nutrient utilization. the amino acid utilization may have been compromised with the whey protein because of the malabsorption.

The profile comparison between the two is pretty balanced. Each side has one over the other. Never though the arginine content would be substantially higher in pea protein vs. whey protein.

thats what i gathered, but i did a little more research and i see pea protein is slow acting and thats not what i wanted

the person who told me this was also under the impressed it was still 5/lb...now its 10/lb just like whey protein

I'm unfamiliar with the digestion rate of the corresponding supplemental protein, but I would think the pea protein in regards to whey protein action on muscle synthesis wouldn't be an extremely detrimental factor in maximizing the anabolic environments.

I posted this study up a few months ago. I think it's useful to know, as there are plenty of people who don't get on with casein, whey or even whey isolate, or who are vegan etc. It may not be perfect but essentially what this shows is that it's good enough that it won't negatively impact on protein synthesis if you're forced to use it. I say 'forced' though because nobody in their right mind would voluntarily drink this awful tasting protein LOL!
 
yeah i heard it was horrible

what is a good cassein protein, and a good normal whey? (low calorie preferably)

(fast and slow actings)
i was using optimum nutrition before
 
I only use pure unflavoured unbranded stuff nowadays... I add any flavour/carb/fats/fibre etc myself. I used to get quite bloated/ill from all the crap they add to most commercial proteins.
 
I'd recommend the Aussie brand I use for almost every single supp I buy (Bulk Nutrients), buuuuuut alas I doubt they ship overseas (and you'd get a better price buying your usual stuff, given BN is cheaper in Aus thanks to the bullshit price inflation once something lands on our shores).
 
I just checked them out Trozzle. For Australia those prices are very good indeed. And given that the best whey comes from our antipodean friends in NZ and Aus, that's a good deal. Sadly, can't get it over here in the UK, although I am able to get hold of pure New Zealand whey.
 
I love that 'for Australia' bit :p it's true....haha bloody Australia tax on everything. But yeah, I love Bulk Nutrients. Given the whole lack of regulation in the sports supplement industry and some companies blatantly lying about the actual content of their products (like 90% claimed protein, but only 50% on testing), they welcome anyone to show up to their mixing facilities unannounced and request a walkthrough to observe first hand exactly what's going into each product haha
