is nitrotech worth buying?
Yes.....IF you can get it a discount price.
I don't use it that much, unless GNC has it marked down. Usually, it's the RTDs; in the past, it's been the trial-sized ones (of the discontinued Orange Creme and Chocolate Cinnamon Swirl, both of which gave me a headache). I've used MESO-TECH (w/Nitro-TECH) in the past and liked it, for the most part. I have found a good deal, where the MESO-TECH MRPs (w/Nitro-Tech) are marked down to $21 for a 20-serving box. I may get some, when I run out of protein powder.
I missed the Fruit-Flavored RTDs, Grape and Fruit Punch. Those were great!!! The last ones I got were 4-packs marked down to $4 a piece. The bottled ones were all whey; whereas the canned ones were/are blended protein.
I haven't tried NITRO-TECH Hardcore. But, with the Gold Card and Muscletech's "Buy one; get one 50% off" sale, it may be worth a try.
