Sounds like you are an "endomorph," as much as I hate that terminology. In other words, are you the type to easily put on fat? If so, Muscle Milk is probably not the thing for you. Stick with a simple protein powder, and use fish/flax/hemp oils for your w3 acids.
You can still order Biotest's Grow!, just not through vendors. They have started doing direct sales on a good number of their products, which has caused a pretty nice drop in prices. If you are looking to order, I would highly recommend you get the Low-Carb version. It is easier to mix and more versatile. Go with chocolate or vanilla. (The vanilla is surprisingly good--it's the only low-carb, low-fat vanilla I've ever had that was palatable in water.) The strawberry was a big disappointment--sort of like a rancid version of Frankenberry cereal. Then again, I've never had a strawberry that I liked other than MyoPlex. The two new flavors (orange and banana) are just okay.
Here is the link where you can order it, if you are interested:
