Hi guys I've been taking jack3d for over a week now and I'm now taking 2 scoops before a workout and it's completely changed my workout ! I'm lifting more and more reps it's f*ckin great,I'm like a machine in the gym now ! The only bad thing is sometimes it makes me feel like I'm on a comedown after a workout but the majority of the time it doesn't.Another thing is the beta alanine makes your skin feel like its burning and lips tingle and your itchy but I love this it just makes me go crazy ! Great stuff it gets you JACK3D if anyone has any questions about this stuff feel free to askbtw this is the first PWO I've used aswell.
