Got my box of Hyper Pump about a week ago and been sick and blah lately but hey, here's my reviews after using roughly half of my box!
Taste: GREAT. It tastes exactly like if you drank the unfrozen liquid of a Lime Fla-Vor-Ice.
Pump: GREAT. The first two times I used it was moving towards carb depletion (high volume) and got a great pump -- even on the second workout when I wasn't carb saturated! In addition to that, I used it twice for low-rep strength workouts and even got a nice pump out of that -- at only 3-5 reps! Pretty impressed with that..
Energy/Endurance VERY GOOD. I don't believe this is marketed as an endurance product and that's probably a smart move -- but, it most certainly does give a nice energy boost (especially for the initial 30-40 minutes after drinking it). As long as workouts are kept around that range, it certainly helps crank out an extra rep or two (which I consistently have done while using it). Also, very intrigued at the addition of Yohimbine, which is a wonderful addition to the product -- especially for someone on a cut!
Sensations: GOOD. The Beta-Alanine is a little too much for me, and the tingling can become slightly bothersome. However, this isn't to say that heavier lifters (I've been cutting am only sitting at about 187) or those who are more resistant to BA (which I'm certainly not!) might find the dosage very appropriate.. aside from that, I felt no ill effects -- only positive ones!
Convenience: GREAT. It's a tiny little bottle that has a sizable impact on performance -- what more can I say? No mixing, no measuring, just extremely convenient and quick to take!
Overall Opinion: VERY GOOD. As a preWO supplement, Hyper Pump is a great option and I suggest anybody in the market give it a shot. An increase pump, energy, and drive is definitely there. It's convenient, tastes great, and does what it says it does! A very good, solid product that I am happy to be using!
An additional thanks to Laze for allowing me to try this out! I'll be sure to update this again once I've finished the whole box.
