YES! it was MASS-TECH, that stuff was legit, well made with good clean ingredients, great sources of carbs inside. I haven't seen it around in years, was a great product. And I do remember the cookies n creme Met-RX bars! YUM!!!
Again, Mass-Tech is still being sold. In fact, I just went to GNC not that long ago and saw plenty of it on the bottom shelves of the MuscleTech section.
I forgot all about the Cybergenic 3000 Weight Gainer. I wish I could remember the flavor but I remember they had some pretty freaky ones.
I worked at GNC during college and I do remember the Milk and Egg powder by Challenge which was one of GNC's brands.
Also one that i can't say I miss but I remember it was one of the first supplements I used: Lee Haney's Mass Fuel Kit:
Those bars in the kit were pretty tough to eat I remember.
I still have the video tape that came with the Mass Fuel Kit I bought back in '93 (again on clearance from Bally's supplement shop).
The bars were indeed terrible. I tried melting one down and adding sugar; but that didn't work. In fact, it gave me a major headache. Those Mass Fuel bars should have been replaced by those Heavweight Gain bars that Champion Nutrition made (especially the chocolate-peanut butter ones).
The Mass Fuel kit was a bit ahead of its time, if you think about it. It had the Pre-exercise Energy Drink and the Post-Exercise Anabolic Recovery Drink. Both were, more or less, watered-down weight gain shakes (both fairly high-carb, with the Pre-Exercise and Post-Exercise drinks having 15 and 35 grams of protein, respectively).
Today, pre-and-post-exercise drinks are all the rage (you can now add the "during-exercise" drink to the equation). So, for Twinlab to make the Mass Fuel kit was a bit innovative. The only catch is that you'd have to use it for several months (that is, buy SEVERAL Mass Fuel kits) to get any tangible results.
