I've been using Stim-X for the past couple of weeks and here are my thoughts on the pre-workout. First off for the 6 g scoop you get 150 mg of caffeine whereas I usually like to be at around 250+. But surprisingly I had nice energy throughout my training at the one scoop level. I think one scoop would be very good for the average gym goer but since I like my stims my review will be based off of my regular dose of 1.5 - 2 scoops. I found that the recommended 8 oz of water per scoop is right about at the sweet spot although I usually like to use a little less water and throw in some ice cubes. The mixability is excellent with no clumping or residue at all. Going into the Candy Blast flavor I had some high expectations since Nutrabolics Black Cherry Lime flavor is amazing. The Candy Blast flavor is good but not quite as good as their Black Cherry Lime. The flavor and sweetness are balanced not being overly strong or sweet. The flavor reminds me of a bomb pop popsicle and a candy watermelon. The energy was really great and had me focused right to the end of my workout. It definitely lived up to its name of "Stim-X". I experienced some nice tingles from the beta-alanine and along with the niacin and arginine the pumps were good with some nice muscle fullness. Stim-X with its completely transparent label is an all around very good pre-workout. It does what it says the stims really get you going. Although you may want to adjust your scoop size depending on your stim tolerance. Nutrabolics did a very nice job on this one and with no crash.

I chose the Iced Raspberry flavor and honestly at first wasn't sure if I was a fan, but I would buy the flavor again- I did like it. Mixed great! No little particles floating around to leave grit in the bottom of your shaker/cup or in your teeth :D As for energy- here's the kicker....I am usually up at 3 am- at the gym by 5am- and not home until 7:30-8 pm.... in bed by 10pm. So, as you see, not much rest for the wicked. I am a nurse/firefighter and am on the go constantly. That being said...there are definitely mornings that I do NOT want to get up and train.... nor do I have the energy to do so. I have been dosing with a rounded scoop of StimX about 15-20 min pre-workout (I drink more coffee than I should so at my weight this is probably a large serving for me)...and found that this is my sweet spot. No jitters, no headache (which is HUGE for me with pre-workouts- MOST of them I've tried trigger a migraine- NOT Stim-X- and for that alone I would buy it!)- and a very very clean energy- with great focus. I do feel some BA tingles, but nothing distracting at all. Strength has been good- pumps have been ok. Definitely a plus with my energy and stamina though. A noticeable-positive- difference!

Fantastic product for an introductory pre. Mild caffeine content and a good dose arginine and theobromine. Very tasty, but must be stored in the fridge. Overall a good purchase, would benefit someone looking for an energy drink replacement that will actually help when lifting/working out.

I actually got the Peach Mango, but it's not listed here. This has to be the worst tasting Pre-Workout I've ever tried, possibly the worst tasting supplement in the entire universe. It looks brown-ish, like baby diarrhea, definitely smells like rotten mangoes (there was a centenarian and massive mango tree in my school yard, trust me on this, I know how rotten mangoes stink) with a hint of peach. The flavour itself is another entire experience: there's nothing mango-ey or peachy on it - it tastes like you've mixed soil and sugar. With that rotten mango smell, drinking this is a chore! Now, on the effects: I am used to ProMera Sports Beta-Cret and Capsi-blast, which are excellent products, give me an almost immediate kick that lasts for hours. I've used both for ballet, cycling and swimming, with incredible results. Nutrabolics Stim-X has very little effect on my energy levels and definitely doesn't last that long - after one hour or so the kick disappears giving room to exhaustion. I can swim maybe one hour on this, and that's it. Maybe the Iced Raspberry flavour is not that awful, but I'm definitely not giving it a try.

Flavor: Peach Mango I received this product from the forums here on in exchange for an honest review. My background in pre-workout is minimal as I tend to stick to coffee or the occasional white monster energy drink. I also workout more late at night so tend not to use pre-workout so I can still sleep, but decided to give this a try. And when it comes to taste, I've got to say this product is great. Energy I think is there but I wasn't quite sure as I didn't feel a spike or anything that I've read people talk about in pros/cons of preworkouts. Flavor: This is the big one. I haven't tried many others but I've never been a fan of the common fruit punch flavor used. However, this peach mango was a tasty combination. It's more peach than mango but still comes off with good flavor. It also mixes well for the most part, even in juice and I may have also mixed some with half a can of sugar free red bull just to see how that would go. Made for a palatable drink which is a job well done since I only like the flavored red bulls not the regular ones. Energy: I didn't feel a slump or anything despite having it at times when I was a little lower in energy or in one case, very lacking in sleep. I didn't feel a huge jump either but that's fine. I'm not quite sure what I should feel or look for in particular with this kind of product (nor do I know for pump factors but luckily not trying to find that at this time). It didn't give a crash later, so that's a definite bonus. Only suggestion is that it doesn't pair that well with a headache but most stimulants in this classification probably won't go well with such. Overall, it's a good product that has great flavor. Not the highest in energy burst but that also comes with not having a negative reaction in return either. Overall, I'd recommend this for anyone wanting a good tasting peach flavored preworkout.

I actually had the Candy Blast and the flavoring was fantastic. Was a mix between skittles and blue raspberry taste to me. BA tingles came right away but not overpowering. The energy was great with NO crash! No complaints from me and would recommend trying for a pre workout.

A big thanks and mad props to the Nutrabolics team for allowing me to try this product for free! Okay, this stuff is very good. First, you know exactly what you're getting, no prop blend here folks and that's tops in my books. Second, the one scoop provides perfect balance for what you need in the gym. I say in about 10-15 minutes, I could feel it. No jitters or anything of that sort. Third, this product provided adequate pumps along with clean energy for when you really need to go balls deep at the gym. It mixes very well with water without any foaming issues. Again, good, quality ingredients that for the most part are adequately studied so you know what you have working for you. Definitely a keeper for me and highly recommend! Definitely will grab another tub of this stuff when I'm out.

By now i have been using it for the past couple of weeks, and to say the least, i am very pleased with my purchase The energy and endurance i get off of this is incredible, which is exactly what you would expect from a product with the name of "Stim-X" Even hours after i am finished with my workout, i still feel a bit stimmed up, nothing too insane ...although i might be saying otherwise if had dared to 2 scoop this LOL The pumps were very good as well! I had a shoulder workout earlier today and was doing moderately high rep with lower weights..and wow, the pump was unreal! Probably the best pump ive ever had in my shoulder! Which was partly because i was REALLY focusing hard on activating the muscle, but mostly because of the added Arginine. Arginine is one of my fav supps for pumps, and im super happy to see it in the mix Mixability and taste are near perfect. I mixed a scoop in about 10 ounces water and found it a little too sweet...14 ounces was the sweet spot for me. Black Cherry lime tastes freaking amazing. Just a heads up, i usually just dump a scoop in my mouth and chase it with water, and i had ZERO issues with taking it this way...simply because the scoop is so dam small and the flavor is so good. Focus, well, surprisingly i got a good amount of focus from this pre...i say surprisingly because it it wasn't advertised on the tub. But i guess the energy formula is just SO on point that it even enhances the mental side as well Energy/Endurance - 10/10 Focus - 9/10 Pump -10/10 Taste/mixability - 10/10

Best preworkout on the market ! The flavour , the pumps , the focus ... im left speechless .. Flavour : not to sweet with 1 scoop Pumps : works instantly and lasts forever , less sets needed ! Also the preworkout kicks in within 5 minutes and there is absolutely no crash after your workout . All it does , is make you super hungry but that’s about it .

Holy f*ck*ng sh*t! Stim-X is a recommendation if you go really hard in the gym. One scoop kicks in in less than 5 minutes. It gave me that pump and really wakes you up. It mixes well with water and no energy crash. All pump and energy. I thought my old pre-workout was strong (Shadow-X) until I gave Stim-X a shot. I'm glad I did and I'm coming back for a second tub once I run out.

Flavor: Candy Blast Taste: I was really excited about trying this product out. I had heard a lot of great stuff about the Candy Blast flavor with other Nutrabolics products, so I couldn’t wait to get this in the mail. The flavor is great. It is sweet, so I recommend more than the suggested 8-10oz of water. It definitely has a flavor similar to that of the old school “bomb pop” popsicles. And to me the flavor is more enhanced with the extra water. Also, it might seem weird, but it’s worth noting that it does taste good even stacked with other flavored supplements, such as Waxybolic Peach Mango. Since I really like tart flavors, I have to give the edge to Black Cherry Lime. But still, I give Candy Blast flavor a 9/10. Benefits: Here’s where it really gets fun. Most people would say effects should be the primary focus and flavor secondary. I mean, who wants a great tasting product if it’s not going to deliver the benefits that it promises. Stim-X claims to give you explosive energy, maximum performance, insane muscle pumps, while it ignites your metabolism. I’m glad to say, they delivered. Focus: I was definitely focused on the workouts. Even though “focus” isn’t even one of the claimed benefits, I was completely tuned into what needed to get done at the gym. I give focus a 10 out of 10. Energy: Though it has less caffeine than its predecessor Supernova, Stim-X still sets the bar for other preworkouts. With only 150mg of caffeine I felt great the entire workout! There’s nothing worse than being in the gym and not having the motivation because you’re too tired to function. You don’t have to worry about that with Stim-X. Even though I’m pretty stimulant tolerant, I still felt amazing. I give energy a 10 out of 10. I also loved the feel from the thebromine and the synephrine. I was hot within a few minutes of starting the workout and I had a heavy sweat going when it was all said and done. Pump: Pumps were great. Stim-X has enough arginine, beta-alanine, and niacin to really get your blood flowing. You’ll look forward to arm workouts. I give pump a 10 out of 10. Endurance: I had lasting energy for the duration of my workouts. It’s good to know that you have a product that can keep you going without having to worry about crashing mid-workout. Stim-X gives you sustainable, explosive energy that gets you through. I give energy a 10 out of 10. Label: I love the “100% transparent” label. There are no proprietary blends hiding the dosages of ingredients. The “energy matrix” is completely broken down. I would like to see all companies go to a completely transparent label. I give the label a 10 out of 10. Mixability: No mixability issues whatsoever. I threw in my Stim-X in a shaker cup with my water and it mixed great. I give mixability a 10 out of 10. Value: At $26.99 you get 30 servings for approximately $0.90 a serving. I think this is a good deal for what you’re getting. I give value a 10 out of 10. Overall Score: Overall, this is a wonderful product. You should definitely enjoy it and it’s worth a try. I give it a 10 out of 10. Even if you don’t prefer the Candy Blast flavor, this product does what it says it does. (Although, the Candy Blast flavor is good!) Pros: Great benefits all around! Cons: None.
