Agcsy and greenmountainpatriot, the shakes I've been drinking are just whey protein. I buy 10# bags of Optimum Nutrition's whey protein for $49 from [url]www.dpsnutrition.com[/url]. That's the cheapest source I've found so far, and while $50 seems expensive, it will last a long time. I have about 55g of protein in each shake.
Since I'm having such a terrible time of gaining weight, I'm going to start adding some dextrose (a carbohydrate) to each shake. I suggest doing that for you for the shakes you have after working-out. Agcsy even though you will gain weight from the dextrose, I still suggest it for your post-work-out shake since it will help with recovery. I'm probably going to add 25g of dextrose to my shake, but I'll probably end-up changing that after trying it. If you know where to shop (like a local brewery or bulk packaged from a good health food store) you can find dextrose (a carbohydrate) for $1 per pound. If you add 22.5g of dextrose per shake to your whey protein, you can make 20 shakes per $1 worth of dextrose. It's very cost effective. If you can't find it locally, [url]www.thebetterhealthstore.com[/url] has it for about $1 per pound plus shipping.
I've been lifting weights now for 42 years, and I've become much more serious about it lately after having my first year of not making gains. One day, I'm going to have to accept going downhill, but I'm not ready to yet.z
