BSN No-Xplode & Gaspari Nutrition Super Pump 250 are not creatine products rather they are pre-workout nitric oxide products. Yes both do contain creatine but not enough to be considered creatine products. In other words the amount of creatine per serving would not be enough to saturate your muscles. Both are very good pre-workout products.
MuscleTech Nitro-Tech & Cytosport Monster Milk (only 1 gram of creatine) are both protein drinks.
Muscle Tech Cell Tech is a creatine product. This product is a creatine product that uses sugar to cause an insulin spike which in turn will drive the creatine monohydate into your cells. As time has gone on many people have moved away form these types of creatine transport systems opting for lower carb varieties. Also many products are using different forms of creatine. For instance gaspari Nutrition Size On uses a creatine gluconate instead of creatine monohydrate.
