Metabolic Drive® provides the most technically advanced and highest-quality undenatured pure whey isolate and micellar casein in a highly concentrated, great tasting, easy-to-mix shake.

The formula's whey isolate is gently membrane filtered to minimize lactose, carbohydrate, and fat, then instantized for superior dispersibility. It's a rich source of branched-chain amino acids and one of the faster-acting proteins, making it ideal for jump-starting the muscle-building process.

The micellar casein in Metabolic Drive® is also gently membrane filtered. Even though it's more slowly digested, it has a distinct advantage over whey isolate due to its ability to amplify nitrogen retention, and increased nitrogen retention is essential for muscle growth. This factor alone makes micellar casein the ideal muscle-building protein.

Metabolic Drive® is designed to be stand-alone protein supplement for athletes and bodybuilders who want to maximize muscle mass or increase athletic performance. Metabolic Drive® is the ideal super quality, muscle building, performance-enhancing nutrition.

Metabolic Drive® Protein Magic

Something extraordinary happened me in 1993, something that changed everything.

I don't remember the day or even the month or even the exact circumstances — I only remember receiving a box from a company in Golden, Colorado. Inside were two plastic canisters, one labeled MET-Rx "Base" and the other MET-Rx "Plus." The instructions were to take two scoops of the Base and one scoop of the Plus, and mix them in milk or water.

I took one sip and my palate felt... okay. My tongue didn't go into convulsions.

You have to realize that prior to this, protein drinks were in a dismal state. They tasted like soup made from that thing a Sumo wrestler wears around his enormous waist and through his enormous butt cheeks. Furthermore, the price for drinking them (in addition to the horrible taste) was enough gas to float a blimp and often, gastrointestinal cramps.

But this MET-Rx stuff was different! It tasted pretty good. It didn't cause me to become socially repugnant. My gut didn't convulse in the aftermath. What's more, as the weeks went on, you could actually see something happening to your body that sure as hell didn't happen when you drank other protein drinks! You got harder, stronger, bigger!

It was puzzling. The list of ingredients didn't reveal anything all that weird except for some mysterious protein blend called Metamyosyn. But hey, why look a gift horse in the mouth or any other orifice, for that matter? I was hooked. As were about 50,000 other lifters in the country. It was, to that point, the greatest thing that had ever happened to bodybuilding.

MET-Rx Lost Its Kick

But then something changed. Subsequent batches didn't have the same kick and instead of producing it in two containers, they combined the "Base" and the "Plus" into one formula. Oh, it tasted the same, but your body knew something was missing.

So the years went by. You started to think that maybe you'd just been imagining the effects. After all, why would any company reformulate something that had been so effective? Why would any sane company rip the guts out of what had been a miracle?

The Secret: Micellar Casein

I didn't know then but I know now. The secret to the muscle-building effects of the old MET-Rx was an exotic protein called micellar casein. They stopped including it in the formula because it was scarce and very expensive to produce, like trying to catch a snowflake in Maine and then shipping it intact to Arizona using UPS. Oh, it was doable all right, but it was incredibly expensive.

But then MET-Rx started to get competition from other companies who were using price-war tactics to drive retail prices down. The tactic worked. MET-Rx was forced to get their price points down so they could sell their products to the giant retail stores where women could buy baby's diapers and hubby's protein powder at the same place.

So MET-Rx changed into just another protein drink. While they continued to list Metamyosyn on the label, the formula no longer contained micellar casein.

Sure, there are companies today that list micellar casein on the label of their protein products, but they're like those bargain basement K-mart jewelers who put an atom's worth of gold into a bracelet or necklace and charge you a year's pay because it's "gold." In other words, today's "advanced" protein powders don't have enough micellar casein in them to add muscle to a hummingbird.

Micellar Metabolic Drive®

Biotest's Metabolic Drive® protein, on the other hand, has all the micellar casein of the original legendary MET-Rx and more. But before we talk about how and why Biotest did it, maybe you need to know why this micellar protein stuff is so cool.

In the simplest words possible, micellar casein is the undenatured form of casein found in raw milk. All of the amino acids are intact, unprocessed and unaltered. They are possibly the most exotic proteins in existence but ironically, they're destroyed when the milk is processed in any conventional way, which means that the good properties of casein are magnified, increased exponentially.

Micellar casein has antibacterial action. It leads to increased nutrient absorption and even increased HDL levels, and it even has immuno-modulatory effects and opioid-like peptides that might ease achy joints and muscles.

Perhaps most importantly micellar casein amplifies nitrogen retention, which is the physiological state that's essential for muscle growth. This simply means that Metabolic Drive® is the ideal muscle-building supplement.

And for those who consume protein at bedtime and then wake up in the middle of the night to eat again, forget it. Studies have shown that postprandial leucine balance remains high up to 7 hours after casein ingestion. So, drink Metabolic Drive® at night and put your mind at rest, because you'll be insured of 7 or 8 straight hours of growth.

If Biotest were selling Metabolic® on the shelves of health food stores, the cost of a single bottle would be almost a hundred dollars. I doubt there'd be many buyers at that cost. But given that we don't use middlemen, and the only place you can get Metabolic Drive® is direct from Biotest, we're able to sell it at the ridiculously low price of $39.99 (and lower for multi-unit purchases).

The way we figure it, with its phenomenal taste, luxurious mouth feel, superb nutrient profile, humungous amounts of micellar casein, and ridiculously low price, you're just absolutely nuts if you don't at least try Metabolic Drive®.
