Battle of the MRPs by Mark-Anthony Bailey

You knew their names even before you started bodybuilding. Met-Rx and EAS Myoplex are two of the best selling supplements on the market. Both are MRPs (Meal Replacement Products), meaning that they could be used in place of a standard meal. Therefore, an MRP should offer a good balance of total nutrition: Protein, Carbohydrates, Fat, Vitamins & Minerals. Let us compare the two gram for gram............

Both samples are chocolate flavor
Add 16 grams of Protein for 2 cups of milk added

Winner: Myoplex
Myoplex has 42 grams of "Myopro", their own blend of whey, milk & egg proteins. Met-Rx has a great blend also called "Metamyosyn" but EAS wins this one because it has 4 grams more protein per serving.

Winner: Met-Rx
Both Met-Rx and Myoplex have only 3 grams of sugar but Met-Rx has more fiber and less total carbs keeping it a lean choice.

Winner: Myoplex
Close one here but Myoplex won as it has only 2 grams of total fat (Met-Rx 2.5 grams....oh well)

Winner: Myoplex
With todays foods, its very hard to keep your sodium intake down, so every milligrams counts. Myoplex gets the nod with 50mg less salt than its competitor.

Winner: Met-Rx
Potassium is a very important electrolyte needed for muscle contraction. Met-Rx has over double the amount of potassium as EAS Myoplex.

Vitamins & Minerals
Winner: Met-Rx
Here is where it gets dirty. Met-Rx has more Vitamin A, C, D, and E. Myoplex makers forgot to put it Vitamin K. B6, magnesium, zinc, and iron are all relatively close.

Winner: Met-Rx
Met-Rx has been around longer and can be found EVERYWHERE. For a box of 20 packs, you will pay around $33.00 compared to $36.00 and up for EAS Myoplex.

Winner: Tie
Your choice. I like to mix them up with alot of fruits, ice cream etc. I think Myoplex has a more creamy taste but both are excellent.

Do they work? Yes, when taken correctly with a proper diet and exercise program. You can't go wrong with adding one of these drinks once a day to your supplement plan. In fact, MRPs along with creatine is a great, cost effective way to supplement your diet adding to recovery, strength and size.

My MRP of choice?
Winner: Met-Rx
Met-Rx is cost effective, packed with a great balance of nutrients, comes in a wide variety of flavors, mixes easy with milk and is a quality brand you can trust. I know alot of people still swear by EAS (I was one of them of awhile), but stepping back and seeing the whole picture, I think Met-Rx is the better buy.
