Actually, buying protein powder as meal replacements is slightly more expensive than people think. Lets say for arguments sake, most people take in 400Kcal per meal, which is pretty darn reasonable. (more or less 4 scoops)
So, your getting roughly 8 "meals" per container. We'll say a can costs 30 bucks, once we include shipping. That equates roughly to $3.75 cents per meal.
Im not on anyones side, I have acutally yet to use Metabolic Drive. Lately, I use MuscleMilk or HDT ProBlend 55. Im in college, so cost is a big factor. Regardless, just like everyone has said, I think you get what you pay for.
For most of us, getting quality protein powder typically just means tightening some corners here and there. For some, we tighten our belts just to get a 20 dollar can of Whey. If you have the means,I think supporting a site like this is great, because you basically get EVERYTHING you need other than someone doing work for you to get in the best shape of your life.
To answer your question, I wouldnt hold out if you are waiting on Biotest. Even if they already had it formulated, it would be a while before they were ready to get it on the mass market and probably a while before T-Nation.com was set up to take orders for it.
