To me it's really amazing you've made the progress you have becuase I've seen studies showing that using whey alone is not great at all for building muscle mass compared to protein blends or whole food.
pobrecito,
Thats an interesting comment. I'd like to look into this a bit more. I have always thought that whey is the best protein for bodybuilders (Whey Isolate in particular). I'll get back to you about this; but, thanks for bringing it up. For now...
Okay, granted I did not do a very indepth search; just did one quick search with key words "whey" and "muscle" on pubmed. Couldn't find anything comparing whey VS protein blends; but, I did find this:

The effect of whey isolate and resistance training on strength, body composition, and plasma glutamine.Cribb PJ, Williams AD, Carey MF, Hayes A.

Different dietary proteins affect whole body protein anabolism and accretion and therefore, have the potential to influence results obtained from resistance training. This study examined the effects of supplementation with two proteins, hydrolyzed whey isolate (WI) and casein (C), on strength, body composition, and plasma glutamine levels during a 10 wk, supervised resistance training program. In a double-blind protocol, 13 male, recreational bodybuilders supplemented their normal diet with either WI or C (1.5 gm/kg body wt/d) for the duration of the program. Strength was assessed by 1-RM in three exercises (barbell bench press, squat, and cable pull-down). Body composition was assessed by dual energy X-ray absorptiometry. Plasma glutamine levels were determined by the enzymatic method with spectrophotometric detection. All assessments occurred in the week before and the week following 10 wk of training. Plasma glutamine levels did not change in either supplement group following the intervention. The WI group achieved a significantly greater gain (P < 0.01) in lean mass than the C group (5.0 +/- 0.3 vs. 0.8 +/- 0.4 kg for WI and C, respectively) and a significant (P < 0.05) change in fat mass (-1.5 +/- 0.5 kg) compared to the C group (+0.2 +/- 0.3 kg). The WI group also achieved significantly greater (P < 0.05) improvements in strength compared to the C group in each assessment of strength. When the strength changes were expressed relative to body weight, the WI group still achieved significantly greater (P < 0.05) improvements in strength compared to the C group.
