RSP Nutrition has the perfect workout stack! Do yourself a favor and get yourself some DYN.O. and AMINOLEAN for explosive pumps, mental focus and energy! Easily my favorite tasting supplements on the planet!

This product was fantastic! Great energy, just enough tingles, and got a good pump. And the taste is great too! I really appreciate the transparency about the ingredients, I like a product that is straighforward as opposed to full of 'proprietary blends.' Highly recommend this pre!!

I take a bottle of this with me to work, drink it prior to my lunch workout. It’s great! Gives me a boost of energy without feeling jittery and I’ve even cut out my afternoon coffee with this!

One of the best pre workouts I’ve taken . Strength and focus are unbelievably good . No fatigue throughout the workout . Would definitely buy again and recommend to anybody looking for a preworkout .

This was my first time trying this product and I must say I’m impressed. I honestly can’t distinguish feel between any pre workout I’ve ever taken(they all give me energy) what should out for me was taste and how quickly the energy came on. Literally about to take some now and work legs

Awesome product; does exactly what the label says it will do...crazy vasodilation. To really get the most out of this product, I think it should be used once you're in the sub 13% BF range (men) to to see some signs of veins. Right now I am about 9% body fat and I am loving the visual effects of this product in the gym. As far as the pump...I believe it really depends on your nutrition.

I've been using this product for about two weeks now. I must say hands down one of the best pre-workouts I have used in a long time and I've tried them all from c4 to Jym and I must say this is in a class of its own. I'm super focused, pumps are amazing and no jitters I can take this hit the gym hard for two hours and get home and fall asleep, Unlike most pre workouts where I would have trouble falling asleep this isn't a problem for me when taking this. The wild berry is pretty good and easy drink. Great product so far!!!

This tastes really good and it helps me push through my workout. Definitely top five preworkouts I have tried in a long time. It doesn’t leave me feeling crashed and it’s pretty gradual.

Great product. Great pumps and energy. Loved the beta alanine tingles
