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.

This is an interesting product for modern dark labs, the flavors i've tried each were alright.. a lot better than their flavor systems of old. The pre kicked in very fast possibly within 10 minutes and as that approached 30 minutes a wave of clean energy hit me.. very enjoyable for any workout I put in front of Diamond and I never experienced any side effects. I was concerned of a sleepy effect from the kanna and the lack of yohimbine but these concerns never materialised into anything detrimental. I never noticed a crash or comedown and the effects lasted hours after the workout was over, I would advise this as a solid stim junkie pre workout in the current age but not the absolute pinnacle of what's on the market currently

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.
