Which product is better? Help is greatly appreciated.
your talking about this correct...
NP Mass/Pump Stack?
Well what I can say is that about the only similarity I see is the fact that they both contain a form of creatine. Neovar is a creatine yes, but also has a nutrition repartioning aspect to it with the inclusion of Banaba and Gymnema sylvestra.
The Mass Pump stack is used for just what it sounds like... Creatine to provide intracellular water absorption, Cit Malate (non essential Amino Acid) increases N.O. production, reduces lactic acid, and increases ATP which can in turn be used to increase energy. As for Arginine is it primarily used for "pump" purposes as well by increasing N.O.
Personally, I believe the Mass Pump stack to be more used as a pre-workout product replacement like Superpump or N.O. Xplode...not so much a daily creatine product. Hopefully what I gave you will help you determine which is best for your goals. Good Luck, I'm sure other memebers will chime in as well.
