Energy comes on fast and feels very intense, more like urgency than a good mood or uplift. Focus is strong and narrow, but it feels aggressive and can be uncomfortable if your tolerance is low or you have anxiety. Pumps are average since the stimulants tighten blood flow, but output and training volume stay high.

Bottom line: Best for high-tolerance users who want aggressive, fast-paced training sessions, not for relaxed or feel-good workouts.

Barbarian by Dark Labs
This is a special pre.. The taste was really not nice but in a smaller amount of water it wasn't as bad. The effects were active fast and I mean it began in under 15 minutes! This feeling grew over the next 40 minutes and strangely a final kick occurred around 90-120 minutes in.. I had amazing mind muscle control and my endurance even with heavy weights was heightened to the upmost degree. I found the effects lasted around 10 hours and I didn't crash, however the tolerance with this pre grows more than almost any other pre so only use it once every 7-10 days or the euphoria noticeably lessens and fast! I would say music was much more enjoyable on this and the pumps were even potent with this product.. I would certainly recommend it.

With a product as enjoyable as crack barbarian where should I begin.. Firstly I will say the taste is the only thing I didn't like about this pre workout, juicy grape had a cough syrup taste that was not enjoyable. I have taken this product at 50%, 75% and 100% of a dose and I will be writing about the full dose: The effects kick in extremely fast and after 10 or so minutes you feel the first rush of energy, then with every 10 minutes that goes by more of the ingredients activate. Strangely this product has a second wind that kicks in around the 90 minute mark which is quite rare in a pre, it makes it so even the most intense gruelling workout can be completed with such ease. I felt much stronger when on barbarian and the mood elevation was one of the best of all time, the full dose can be too much for some people so start with half a scoop at first and if that is enough for you then you get double the amount of servings! The pumps were the weakest of the effects but still nothing poor in the slightest and the effects lasted around 10 hours with zero crash or trouble sleeping. Overall I would give this product a 9/10 that could only really be made better if the taste was better.

The best pre workout when preparing to commit a series of war crimes
I’ve tried various doses of Crack Barbarian because on first attempt, 1 scoop was too strong. I completed a killer workout but afterwards felt like I was still ready for more and probably too stimmed for the day to start. After that I tried a half scoop and it felt like it just wasn’t enough. I completed a workout at 3/4 of a scoop which seemed perfect to me. After a few uses of 3/4 scoops, I found myself back at a full scoop and came to really enjoy this pre workout. What sets this one apart from the other varieties of crack is the DMBA. At 100mg it’s a hefty dose that brings in the physical euphoria, almost like you’re working out from a 3rd person perspective. The DMHA at 200mg along with 500mg of eria jarensis, and 750 of BPEA really bring in such a euphoric head buzz that brings about a giddiness when coming up to challenging sets of weights. This pre workout is one that delivers on performance and productivity. I’ve found myself saying things like “this is what they need to be feeding the troops in front line combat zones” and “this is perfect for committing war crimes!” I feel myself being extra aggressive with the weights where failure is never an option. I often find myself murdering the weights in cold blood but in a harmonious and rhythmic manner with the music because this is one of those that really makes the music more enjoyable, in combination with the workout. The pumps are pretty good, 6000mg of citrulline malate but it’s supported by a gram of agmatine sulphate. I wouldn’t be the best to review the clinical 3.2grams often found in pre workouts because I feel like I’m too accustomed to the tingles at this point. The alpha GPC at 500 mg each don’t really mean too much to me. I definitely get more from the three types of caffeine, especially the fast acting caffeine citrate. That long lasting stimmed up effect that I mentioned is likely due to the alpha yohimbine, the DMBA and DMHA. I feel like DMBA especially, seems to last me for a long time. I’ve compared this to Euphoria by star lab nutrition because of the DMBA content and that “third person” feeling while working out. The difference is that I crash pretty hard from Euphoria, I still don’t know if I’ve ever come down from the first time I’ve taken Barbarian. The flavor is grape and it’s probably the least offensive tasting Dark Labs product out there.

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.

Strangely this product has a second wind that kicks in around the 90 minute mark which is quite rare in a pre, it makes it so even the most intense gruelling workout can be completed with such ease. I felt much stronger when on barbarian and the mood elevation was one of the best of all time, the full dose can be too much for some people so start with half a scoop at first and if that is enough for you then you get double the amount of servings! The pumps were the weakest of the effects but still nothing poor in the slightest and the effects lasted around 10 hours with zero crash or trouble sleeping. Overall I would give this product a 9/10 that could only really be made better if the taste was better.

The best pre workout when preparing to commit a series of war crimes
I’ve tried various doses of Crack Barbarian because on first attempt, 1 scoop was too strong. I completed a killer workout but afterwards felt like I was still ready for more and probably too stimmed for the day to start. After that I tried a half scoop and it felt like it just wasn’t enough. I completed a workout at 3/4 of a scoop which seemed perfect to me. After a few uses of 3/4 scoops, I found myself back at a full scoop and came to really enjoy this pre workout. What sets this one apart from the other varieties of crack is the DMBA. At 100mg it’s a hefty dose that brings in the physical euphoria, almost like you’re working out from a 3rd person perspective. The DMHA at 200mg along with 500mg of eria jarensis, and 750 of BPEA really bring in such a euphoric head buzz that brings about a giddiness when coming up to challenging sets of weights. This pre workout is one that delivers on performance and productivity. I’ve found myself saying things like “this is what they need to be feeding the troops in front line combat zones” and “this is perfect for committing war crimes!” I feel myself being extra aggressive with the weights where failure is never an option. I often find myself murdering the weights in cold blood but in a harmonious and rhythmic manner with the music because this is one of those that really makes the music more enjoyable, in combination with the workout. The pumps are pretty good, 6000mg of citrulline malate but it’s supported by a gram of agmatine sulphate. I wouldn’t be the best to review the clinical 3.2grams often found in pre workouts because I feel like I’m too accustomed to the tingles at this point. The alpha GPC at 500 mg each don’t really mean too much to me. I definitely get more from the three types of caffeine, especially the fast acting caffeine citrate. That long lasting stimmed up effect that I mentioned is likely due to the alpha yohimbine, the DMBA and DMHA. I feel like DMBA especially, seems to last me for a long time. I’ve compared this to Euphoria by star lab nutrition because of the DMBA content and that “third person” feeling while working out. The difference is that I crash pretty hard from Euphoria, I still don’t know if I’ve ever come down from the first time I’ve taken Barbarian. The flavor is grape and it’s probably the least offensive tasting Dark Labs product out there.
