Koka Labs Doomsday Destruction
Doomsday 1 scoop 18g, sense of urgency came so quick i shit my pants, well I made it to the toilet but you get the picture. The energy swooped in at about 15 minutes, followed by a nice head buzz and locked in focus. The weights were moving as if I were on the moon. As for the mood, it was a mix of aggression and nervousness but also calm. Then, once it all leveled out, I was just in a bubble and just moving along with the workout. Endurance was good because the alpha yo smoothed out, I was sweating like a madman also. Now that the dust has settled, I'm in a great headspace, wide awake and in a good mood. This was definitely a great pre, and there were some PRs in today's workout. This was like machine pre but with a little less aggression and less panic.

Strongest thing I've ever taken
Hit within 20 mins, crazy tunnel focus. The yohimbine is no joke — started sweating 10 mins into my warm-up. Not for beginners. Energy lasted the full 2 hour session.

Taste is rough but the energy is real
Pina Colada flavor tastes more like chemicals but who cares. Pumps were solid and focus was dialed in. Wouldn't recommend for anyone under 180lbs.
