Black in, not out!
Not bad at all. Once I got to the gym, I was in the zone. Focused, not jittery, but definitely ready to throw weight around. No crash after, just that weird high-alert calm where your body’s tired but your brain still wants to clean the garage. Taste was fine. Honestly, I don’t even remember drinking it. Im not here to savor the flavor. Mixes fine, but again, you’re not taking this for the mouthfeel. You’re taking this because you want to go absolutely feral for an hour and a half. If you’re a high-stim junkie like me, this won’t melt your face off, but it hits solid. It’s not the most intense stim out there, but it’s smooth, reliable, and actually lets you focus instead of just vibrating in place with the tingles. For the price, it’s a really solid pre. Gets the job done without turning your soul inside out. Would I take it again? Already did

Better Than Morning Coffee
Nightmare - Blood Red. To get my day started, I take about 8 - 10 grams every morning with my 5 grams of creatine and methylene blue in about 12 ounces of water on an empty stomach. It's better than coffee and I don't get the caffeine jitters or crash. For comparison purposes, I'm a 56 year old man, 5' 10", and about 215 lbs. If you're looking for a good pre-workout or just a little energy boost, I would definitely suggest trying this Mr. Hyde - Nightmare.

HYDE Nightmare Pre-Workout
Taste: ✅ Blueberry chaos: Surprisingly good. Ideas: ✅ Had about 12 new business plans and reorganized my trauma files. Jitteriness: ✅ Like a raccoon with a vision board. Quality: ✅ Solid. Didn’t feel fake or chalky if that tracks. Hydration: ✅ Electrolytes showed up. I didn’t shrivel. That’s a plus. Energy Level: ✅ High. I cleaned, planned, and side-eyed the HOA while inspecting dirt on my driveway. Functionality: ✅ Works. Just don’t take it before bed unless you want to spiritually sprint through your to-do list at 2am. Final verdict: Would recommend but stretch first and hydrate like you mean it.

Great preworkout and stimulant
Love this stuff gives you the edge you need to keep you going. Good taste good quality effectiveness that pumps up your adrenaline for strength boosting. Mixed properly no stomach aches start out with half scoop of your sensitive to caffeine.

Good product, but...
It is a good product, and it gives me plenty of energy. However, it contains sucralose, which, if used long-term, can be harmful.

Amazing Preworkout
I love this preworkout, gave me a nice pump and powered me throughout the whole workout unlike other preworkouts some ingredients are underdosed but it didn’t affect my workout definitely getting this brand again

Doesn’t work for me
Taste is good but there is no kick for me. I have used C4 and it wakes me up and I am able to hit the gym hard. I saw Hyde’s review and decided to give it a try and I started with half scoop and it didn’t work then I used full scoop, no effect. I am surprised it didn’t work for me I tried to decaffeinate my self but still I am surprised no effect on me. I will surely go back to C4 or maybe will give insane labz a try.
