I refer Animal Flex to almost everyone, even as a staple, like I use it....
AllStarHealth.com <<<hands down the best site for everyday low price....Bodybuilding.com has decent sales here and there but can't match their everyday prices + flat rate shipping....
no offense but gainers are sh*t....1 scoop your choice protein, 16 oz fat free milk, 1 cup dried oats, 1 banana blended, is far greater than any "gainer" protein...
rule of thumb is usually 1-1.5 grams of protein per bodyweight for lifters....obvious foods like chicken, beef/steak, eggs, tuna, yogurt/cottage cheese = easy choices to accomplish your daily intake....
Xtend is pretty good, I still prefer AEN Intrabolic and CL's Purple Wraath, personal preference....
before my shoulder/back injury I joined the 1200lb club with my 3 major lifts at only 25 yrs old and 175 lbs (12% BF) had a 345 Bench, 455 Dead, and 415 Squat <<<yea I know, terrible squat....
