I’ve used several other pump products on the market, and NOTHING compares to the pump I had on arm day from using 2 caps of the Berserker serum. 100/10 recommend!
One of the best pump products I’ve ever used…..highly recommend trying it. I bought the unflavored version and squirted some mio in there and was good to go. Be sure to drink plenty of water pre workout and during to get maximum benefits.
nothing compares to the lift I get on this
Great energy boost after a long day at work and need that push to hit the gym hard. Also doesn’t keep me awake and I can fall asleep easily in the evenings.
Amazing gym sessions on this. I’ve never been so focused and ready to kill it on this. It’s a creeper. You don’t realize it’s on until you get going and you realize you can do anything.
