Gaspari Plasmajet and I force Hemovo2 max both gave me pumps for the 4 hour range.. Glycerol is pretty good too.
I should note that the pump I am speaking of is more of a super increase in vascularity and not a super full type pump as I was pretty glycogen depLeted when using both.Gaspari Plasmajet and I force Hemovo2 max both gave me pumps for the 4 hour range.. Glycerol is pretty good too.
Why do you want a pump for 4+ hours? I honestly doubt any product will promote that. The only thing I could think of is a GDA product, SlinMax gives me food pumps with high carb meals, but you would need to eat 2 huge meals in those 4 hours to get a pump for that long.
