Through my late teens and early 20's I was a fairly hardcore bodybuilder/weight-trainer. A few years off and the weight gains were not in the areas I wanted them. So, at the age of 33, back to the gym, but also wanted to supplement the diet properly in order to lose the additional baggage, and maintain strength and endurance for those high intensity workouts, and get that physique back. I had heard good things about Met-Rx so I started on the Met-Rx program about 2 1/2 years ago. I noticed that muscle gain was not coming very easily, and that my weight was not decreasing either. Though I wasn't gaining significant weight either (hopefully burning fat, and converting to muscle was making this a wash). To make this long story short, I started comparing Met-Rx to a few other "meal replacement/supplement" and protein powders and found this...Met-Rx is LOADED with sugar and not very impressive on protein. It lacks by wide margins the content of key bodybuilding nutritional elements. As compared to an egg & whey protein, Met-Rx isn't even in the same game. I understand that there should be a difference between a protein powder(for weight gain) and Met-Rx, (weight loss / weight control) but I was blown away. I weighed in at 202lbs in May after about 10-12 dedicated months on Met-Rx. (I actually gained about 10 pounds on Met-Rx during training, but still looked fat). As of June 9, I have changed over to O.N. egg and whey protein shakes (2-3 a day depending on my protein count in that particular meal), adding L-glutamine (10g) in two shakes per day. I am in the first week of the creatine maintenance phase. My diet is a TAD more strict...and I'm down to 182 lbs...which is decent weight loss (20 lbs in 8 weeks)...but I LOOK like I weigh 10 pounds more with the lean muscle mass I have added/converted. The muscle has packed on like slabs of beef, the waistline has trimmed from a 34 back to a 30-32. I look and feel like I'm 25 again...and I'm 35. Just wanted to throw caution out there that MY experience with Met-Rx was not what I was led to believe would happen. It is VERY high in sugar and lacks the essentials needed for a serious bodybuilder. Again, this is only my personal experience but I'd shop around and compare before deciding Met-Rx was the way to go. It's a good place to start, since it does provide some nutritional benefits for an increased exercise program, but just can't compete with the good old-fashioned protein and ard training method.
