Nader Qudimat
Pre-Workout Expert · 20 years training

Mood flips faster, normal one moment, then a strong happy lift kicks in.

Training turns effortless, no forcing reps, just locked into the vibe.

Bottom line: Best part is that short-lived euphoric rush that turns your whole workout into a feel-good session before slowly tapering off.

After about two hours, that mood drops off, but a basic energy baseline lingers.

Out of all Crack series from Dark Labs this must be the smoothest one. I personally enjoyed this pre-workout but still it left to be desired a little bit more the main ingredient in this just makes it mellow and maybe a little too much smooth is the Kanna extract. I never had too much problems with L-theanine and in pre-work, but Kanna seem to effect a lot more in terms of getting in the way of feeling the stims to the maximum. Taste is great, pumps definitely need a pump formula stacked on top of it. It is a builder type of pre workout, it never slaps or you don't feel the exact moment when the pre hits. It's an old drama free that will help you with any body part you are going to train I wouldn't say it's ideal for heavy weight lifting PRS and taking the training to the next level but it definitely provides great sense of well-being mood elevation and motivation to train. Post workout never had any issues or crash. Slowly fades away. In conclusion if you are looking for smooth 2 amino pre with no side effects or drama that's a solid choice.

Crack Diamond By Dark Labs
I write this having only tried the apple flavour and for a high stim pre it was actually not too bad, a bit spicy in it's after taste but not one to dread. I found the effects kicked in with extreme speed and I liked that and it contains a whopping 5000mg of beta alanine, it contains no yohimbine like most dark labs pre's but instead has kanna which in my opinion is a smarter option in a pre than for example L theanine. I felt increased strength and power output for even 2 hour workouts, high reps were easy also. The effects lasted around 7 hours and there was no particular crash to speak of, there was a head high and focus that was nothing short of enjoyable. I found the ingredient blend to come together nicely and is a rare take on a modern high stim pre workout. Overall I would recommend this product and if you try it go for full serving only as it contains no yohimbine so the positives raise as the dose increases and a half serving is underwhelming.

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.
