My first time ordering dark stims pre workout after watching many reviews on social media and I must say it didn’t disappoint I ordered the red apple and the flavour was on point with just the right amount of everything I wanted from a pre workout. Keeps me focussed and locked in for my ShredFast sessions and the pump is just as I wanted I’ll be ordering again along with the electrolytes and creatine I’m in the process of changing my supplements brand and I think I’ve found my new one 👌
Really good pre, caffeine is just the right amount and the beta alanine gives a nice little itchy feeling without being too much. Good energy throughout the workout and no horrible comedown afterwards, you just feel normal once it wears off. Would definitely recommend.
gives me the energy needed to have a good lift
Great energy and kick
amazing as seen in the video i’m able to actually sip and enjoy it because of how flavourful it is and it has little calories,pump was insane,felt super locked in and helped me throughout long sessions there’s something with this pre workout that makes me focus soo much totally recommend in best one i’ve had so far will DEFINITELY be buying more
Love using this product does exactly what it says on the tin the reason I subscribed to have it delivered everymonth
Great turnaround from placing order to the taste, will definitely be buying more.
This pre-workout gives good focus
Great pre-workout, plus great tasting. Have it at 5am for a 5:30 start at the gym. Gives my great focus, energy and pump. I feel lost at the gym if I haven’t had it. No sudden come downs, it’s very gradual and can function with a full day in the office.
Amazing taste strong kick works amazingly will be buying more
First purchase from here & wasn't disappointed very tasty & definitely felt a difference during my workout also got the electrolytes pineapple flavour very tasty.
Bonkers brilliant pre workout
This product is amazing. The pumps and energy I receive taking this pre workout is absolutely incredible. Highly recommend!
Really good taste, really easy mix, gives great energy and have no post or mid workout crashes like other brands!
Gave a crazy pump, locked me in big time. Not going back to any other pre, wish I could afford more flavours lol
I love this product!! 💯 recommend! My partner and I both take this product and wouldn’t go back. It Gives you the pump you need to level up and blast through your workouts no matter the length. Absolutely fire of a product. 🔥
Absolutely unreal products! Amazing quality and taste! Pumps last whole workout. Highly recommended!
This stuff is amazing. My legs are pumped!
Absolutely elite quality products and stack! The best pre workout and pump I’ve had in years! Immense focus and can really feel the difference in comparison to other brands I’ve tried in the last few years! My new go to moving forward 💪🏻💪🏻 highly recommended
Really good pump, crash isn't too bad, the flavouring on the cherry is too harsh but other flavours like strawberry orange are perfect
I had only tried one other pre workout before dark stims and it made my shit green 😂. When my first tub of dark stims arrived i was happy to see it was a normal colour, mixes really well and the effects are mind blowing the high dosage of all ingredients gives you the most insane pumps, don’t waste your money on whatever you can get from your gym when this stuff is the same price and gives you reliable performance with less bullshit ingredients. Thank you Dark Stims
Having tried most of the other pres on the market over the last 18 years I had to try this one and this is my review - Mixes very well, smooth to drink and tastes great. No powdery or chemical taste. No huge energy hit but a gradual increase and it doesn’t crash down either. I started with 1 scoop but now use 1.5 and it easily gets you through a 1.5-2 hr session and keeps you energised hrs after. Focus, vascularity and pumps increased. Definitely a new staple for me
The best pre workout I've come across in all factors. Flavour, Quality for Value and Pump. I've been a constant returning customer, other pre workouts don't hit as hard as this one. 👌
best pre
Tasted unreal and mixed perfectly
Best prework
Darkstims Pre-Workout V4 I’ve tried a fair few pre-workouts, and this one genuinely stands out. The energy kicks in smoothly without that jittery feeling, and the focus it gives is proper dialled in, I felt locked in from start to finish. What I liked most is there’s no crash afterwards, which is a big win for me. Taste is solid too, not overly sweet or artificial. Definitely one I’ll keep in my routine.
Consistent boost of energy during the gym, amazing taste too would recommend it again but I only tested one flavour so I will order more
Best tasting pre-workout I've tried. Previously been using DY Nutrition Blood & Guts for a few years, this tastes better and gives me great focus and drive in the gym.
The energy and pump I get off this pre-workout is insane best I have used in years
Using 26kg for 12 reps with the help of darkstims
taste amazing
Great energy
The best pre workout I have tried and I’ve tried a lot
Flavour amazing,pump amazing,focus amazing and price very fair
I’ve tried LOADS of different pres! This is my fav so far! Not as stimmed so don’t get the crash or the jitters but the pump is next level! Tastes good and priced a bit high but worth it!
10 times better then other products I’ve used will definitely be buying darksims from now on
Best pre I've had in a long time. You know it's good when you can actually feel it working before the workout and when it kicks in when you start. Flavours great, not at gassy like other pre I've taken. I'm reordering right after I've finished typing this.
I purchase this for my grandson, he highly recommends it.
