Lots of energy, Great Taste, Affordable - but nothing "off the limits"
I've been using this one for quite some time now and it never let me down. What makes this pre so special or, to be more precise, useful for me is that it delivers a solid combination of multiple aspects which on their own already are very nice (mood elevation, energy, focus etc.) but the way these are combined alltogether makes this pre, especially if one considers the price of

Crz
This is a product that fascinated me after seeing reviews so I got some and here is my experience: It is tasted better than the average pre workout but not quite as good as Excelsior of old but on that kind of level.. it took almost an hour to have me flowing with focus and energy and I liked what it brought to the table. Anything I did in my workouts was easy and the afterglow went on hours post, the strange element is finding the right dose as the 6.8 gram full scoop seems to be underwhelming for most people but once you take it to the 9-12 gram mark it becomes far more special. This is unfortunate as it makes it worse value for money but it's one of the only products currently on the market with some of the feel of the older focus centric style pre's. I would say buy a tub or two and you won't regret it!

Firstly the taste of Crz was a very subtle and tasty blueberry and I found it to be very enjoyable as in better than 95% of pre workouts. Now to the effects of the current 12/28 batch: No beta alanine tingles or niacin flush which is rare for a modern pre workout but anyone in the know will be purchasing something like Crz for the focus. As it pertains to the effects they take a while to kick in, as in upwards of an hour so do not re dose.. wait 90 minutes even as it can take anything from 50-80 minutes to fully activate. The focus is very potent and the mood uplift is noticeable but not huge, just a nice blend of the two around 75/25 focus/euphoria. I have experimented with the standard dose, with one and a half scoops and two scoops. At the standard one scoop it is enjoyable but on the mild side, but once you reach anywhere between 12 to 14 grams the focus and longevity is elevated exponentially. At one scoop it lasts around 5 hours but on the doses I mentioned it is more along the lines of 10 hours. It in my opinion is better for long work days than hard workouts as it's all focus and no pumps or aggressive energy. Overall I would recommend Crz.

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.
