      Exploding through the workouts

      First off, I received the shipment rather fast. I think I got it in 3 days with standard shipping. Second, the preworkout aggression is great. Taste isn’t great but it’s not a deal breaker for me. I just down it real quick. It definitely gets the job done. Lastly, size on is great. It reminds me of sipping on Gatorade but a thicker texture and it taste better. I look forward to working out bc i crave the orange cooler. I’ve been using it for about 3 weeks and my max on bench has gone up 20lbs. My only complaint is I wish there was 30 servings.

      I used Gaspari Products when I was an NCAA collegiate athlete a few years ago, and have always been a fan of the product line. I got back into it with the Swole Stack, and I can honestly say it's the best tasting powders I've ever tried! I went with Mobster Italian Ice (tastes just like a Pina Colada snow cone) and the Lemon Ice SWOLE (tastes like a cold lemon bar, amazing!). I still got the great pump with the Aggression and mind clarity/focus I did with SuperPump MAX back in the day, so pleasantly surprised it worked just as well. I mixed my Lemon Ice during my late night workout with the Anavite (Strawberry) and it's just like Chic-Fil-A strawberry lemonade. Another kick *** stack by Gaspari, so glad I found my way back; just placed another order after just two workouts, highly recommended and you honestly can't beat the price either!

      Rich Does it Again!

      I used Gaspari products a few years back with good results and kept hearing good things about the reformulated" Sizeon -- and, since I was looking for a new stack to rotate into my pre workout routine, I figured, "what the hey, I'll give the "Swole Stack" a shot. So 2 weeks in, I decided I better issue a warning. The Superpump and Sizeon is some serious %$#&. If all you want to do is "pitter patter" around the gym for an hour, BSing and checking out the booty, then this is NOT the stack for you. If, on the other hand, you are looking to rip your freakin shirt off and give the stink eye to anyone that gets within 10 feet of your dumbbell, then this is the stack for you. The pump and intensity is on another level. If you are looking to push for more pounds, increased reps, rip through drop sets and super sets like butter then this is your fix. I take the SuperPump Aggression about 30 minutes before training and then I start sipping the the Sizeon maybe 10 to 15 minutes beforehand. I like to finish the Sizeon by about 20 minutes into my routine and then switch to water. My training lasts a solid 1 1/2 hours and I still have plenty of reserves left in the tank when I finish up. Don't over think it. Just get it and try it. You won't be disappointed.
