What Do the Experts Say?
Tim Ziegenfuss PhD
"This is the simplest, most-effective nutritional strategy in existence to improve body composition and athletic performance. Elite-level workout nutrition, like Surge® Workout Fuel, can double results in body composition during training. If you train intensely, then Surge® Workout Fuel is an absolute requirement. On the other hand, if you're not into hard training, Workout Fuel is overkill for those not serious about training."
Jeffrey Stout PhD
"Anyone can benefit – the strength, bodybuilding, or endurance athlete. This formula is designed to stimulate protein synthesis and reduce catabolism, delay fatigue, and provide sustained energy for any intense or high-volume workout or competition."
"The more volume of physical activity you do (not just weightlifting), the more you'll benefit from Surge® Workout Fuel. The harder you train, the more you need it. If you do nothing but talk to the treadmill bunnies between non-intensive sets, then Surge® Workout Fuel isn't for you. Save it for those who earn it!"

1Why Include Cane Sugar?
Sucrose (cane sugar) is a fast-acting saccharide that helps L-leucine kickstart protein synthesis and aids in early-stage hydration.* It's also a natural sweetener contributing to the formula's ideal flavor profile.
- Begin drinking 15 minutes before training to hydrate and preload buffering substrates.
- Consume while exercising at a minimum rate of one serving (scoop) in 600 ml (20 fl oz) per hour to assure proper hydration and achieve maximum performance levels.
- Continue drinking for up to an hour post-training to substantially reduce post-exercise cramping, balance and replace electrolytes and glycogen stores, and boost recovery.

DOI: 10.3136/fstr.21.499. ABSTRACT: Highly branched cyclic dextrin (HBCD) is a novel type of maltodextrin with a narrow molecular weight distribution that is produced from starch. In this study, we investigated the effects of HBCD administration on endurance performance. Seven elite swimmers participated in three trials, conducted in random order. In each trial, the subjects received either HBCD, glucose (1.5 g carbohydrate/kg body weight) or water (as a control), and immediately carried out 10 cycles of intermittent swimming consisting of 5 min of swimming at 75% followed by 3 min of rest, and subsequent swimming at 90% to exhaustion. The time to fatigue was about 70% longer in the HBCD trial than that in the glucose and control trials, a significant difference. Plasma glucose in the HBCD group was maintained at higher levels during pre-swimming cycles than that in the glucose or water group. These results suggest that HBCD administration enhances endurance performance.

Biosci Biotechnol Biochem. 2014;78(12):2117-9. DOI: 10.1080/09168451.2014.943654. ABSTRACT: We compared the effect of relatively low doses (15 g) of highly branched cyclic dextrin (HBCD) with that of maltodextrin during endurance exercise on the rating of perceived exertion (RPE) in a crossover, double-blind study of healthy volunteers. The RPE increased during exercise and its increase was significantly less at 30 and 60 min after ingesting HBCD than maltodextrin.

PMID: 25270782. ABSTRACT: Background: Aim of the present study was to compare the effects of highly branched cyclic dextrin (HBCD) drink with a glucose-based control drink on immunoendocrine responses to endurance exercise. Methods: Using a randomized, double-blind placebo-controlled cross-over design, seven male triathletes participated in two duathlon races separated by one month, consisting of 5 km of running, 40 km of cycling and 5 km of running. In the first race, four athletes consumed the HBCD-based drink and three athletes consumed the glucose-based drink. In the second race, three athletes consumed the HBCD-based drink and four athletes consumed the glucose-based drink. We collected blood and urine samples before and after the races to analyze leukocyte count and concentrations of hormones and cytokines. Results: Lymphocyte and neutrophil counts increased significantly after exercise in both trials (P < 0.05), but were not significantly different between the trials. Plasma noradrenalin concentration increased significantly (P < 0.05) during exercise in the glucose trial, but not in the HBCD trial. Plasma concentrations of interleukin (IL)-8 and IL-10 increased significantly during exercise in both trials (P < 0.05) but were not significantly different between the trials. Post-race urinary IL-8, IL-10 and IL-12p40 concentrations were significantly lower in the HBCD trial compared with the glucose trial (P < 0.05), although the plasma concentrations of these cytokines were not significantly different between both trials. Conclusion: These results suggest that the HBCD-based drink may attenuate the stress hormone response, and reduce the urinary cytokine levels following exhaustive exercise.
- Takii H et al. Fluids containing a highly branched cyclic dextrin influence the gastric emptying rate. Int J Sports Med. 2005 May;26(4):314-9. doi: 10.1055/s-2004-820999. ABSTRACT: The rates of gastric emptying for highly branched cyclic dextrin (HBCD) and other carbohydrate (CHO) solutions were examined using ultrasonograph techniques. Ten healthy volunteers ingested water, physiological saline, or solutions containing various CHO, such as HBCD, glucose, maltose, sucrose, and commercially available dextrin. After a subject drank one of the solutions, the relaxed cross-sectional area of the pylorus antrum was measured at rest by real-time ultrasonography. The time required for gastric emptying was correlated with the relaxed cross-sectional area of the pylorus antrum. Among all of the solutions tested, physiological saline was transferred fastest from the stomach to the small intestine. For solutions of the same CHO, 5% solution was transferred faster than 10% solution. For CHO solutions other than HBCD, a low osmotic pressure was associated with rapid transfer from the stomach. The gastric emptying time (GET) of HBCD solution increased with an increase in its concentration. A shorter GET was observed for the CHO solutions at 59 to 160 mOsm regardless of their concentration. A sports drink based on 10% HBCD adjusted to 150 mOsm by the addition of various minerals, vitamins, and organic acids was evacuated significantly (p < 0.05) faster than a 10% HBCD solution or a sports drink based on 10% commercially available dextrin (DE16), which has a higher osmotic pressure (269 mOsm). Our results suggest that a shorter GET could be achieved with CHO solutions with osmotic pressures of 59 - 160 mOsm. Therefore, a sports drink based on 10% HBCD adjusted to 150 mOsm by the addition of minerals, vitamins, and organic acids could supply adequate quantities of CHO, fluid, and minerals simultaneously in a short time, without increasing GET.
- Takii H et al. Enhancement of swimming endurance in mice by highly branched cyclic dextrin. Biosci Biotechnol Biochem. 1999 Dec;63(12):2045-52. DOI: 10.1271/bbb.63.2045. ABSTRACT: We investigated the ergogenic effect in mice of administering highly branched cyclic dextrin (HBCD), a new type of glucose polymer, on the swimming endurance in an adjustable-current swimming pool. Male Std ddY mice were administered a HBCD, a glucose solution or water via a stomach sonde 10 min before, 10 min after or 30 min after beginning swimming exercise, and were then obliged to swim in the pool. The total swimming period until exhaustion, an index of the swimming endurance, was measured. An ergogenic effect of HBCD was observed at a dose of 500 mg/kg of body weight, whereas it had no effect at a dose of 166 mg/kg of body wt (p < 0.05). The mice administered with the HBCD solution 10 min after starting the exercise were able to swim significantly longer (p < 0.05) than the mice who had ingested water or the glucose solution. The rise in mean blood glucose level in the mice administered with HBCD, which was measured 20 min after starting swimming, was significantly lower (p < 0.05) than that in the mice administered with glucose, although it was significantly higher (p < 0.05) than that in the mice administered with water. The mean blood insulin rise in the mice given HBCD was significantly lower (p < 0.05) than that in the mice given glucose. The mice administered with HBCD 30 min after starting the exercise swam significantly longer (p < 0.05) than the mice who had ingested water, although the enhancement of swimming time was similar to that of the glucose-ingesting mice. The gastric emptying rate of the HBCD solution was significantly faster (p < 0.05) than that of the glucose solution. However, this glucose polymer must have spent more time being absorbed because it has to be hydrolyzed before absorption, reflecting a lower and possibly longer-lasting blood glucose level. We conclude that the prolongation of swimming endurance in mice administered with HBCD depended on its rapid and longer-lasting ability for supplying glucose with a lower postprandial blood insulin response, leading to a delayed onset of fatigue.

My go to before I work out
I absolutely love Surge. Over the past four or five months it has become my “go to” pre-workout. Mixes well, tastes great and it gives me focus and energy for my early AM sessions.
Keeps up endurance throughout the workout
When it comes to supplements it is often difficult to judge their effectiveness because it usually requires using them for longer periods of time than something like a medicine to gauge how well they are performing and sometimes the effect, if any, can be subtle. But Surge is different. I was using Plazma then switched to Surge. From the very first time I used it until now it has always given me the ability to sustain my endurance until the end of the workout and allow me to put in a full effort on all my planned exercises.
Love this stuff
Have tried many pre workouts over the years. This mixes well, tastes great and there is no tingling in the face/ears like some others. Just clean, focused energy. This is my first repeat purchase of many. Plan to use this for a long time
Good, but not as good as plazma!
Surge is the bomb
Energy, hydration, stamina, recovery - check. If you are not using Surge workout fuel for your workouts, I think you are missing out.
Great energy when training . Seems like better pumps
surge workout fuel
great taste and get good pumps during my workout. will definitely be ordering some more SWF
When I started using Surge, I noticed an immediate effect on performance. I've used a dozen different pre-workouts in the past and never been able to get this level of performance at this price point. Strength, a good pump, and clean product: that is what this gives you. ... Oh, it doesn't taste like cat ****, either.
Never ending energy
The first time I used the newest formulation, I had unending energy to continue through my workout. Even if I lack sleep, I can sometimes feel completely energized after 75-90 minutes of hypertrophy training. Much better than any pre workout/caffeinated **** on the market.
First bag of surge
This product is amazing. I haven’t had pumps like this or the endurance to train like I did in my 40’s
I recently put surge to the test. I chose one of my hardest conditioning days where I know how my body typically responds. 2 x 1000 m sprints on the rower, 8 x 30s sprints on bike, 8 x heavy 60s sled push. Typically I’m pretty crushed halfway through the bike, but after taking surge, I found a new gear. I’m addicted, I won’t train without it. Taste great and they got the formula perfected
for a brutal workout try SURGE
I rotate workout protocols whenever I get bored. One of them is 1.5hr time under tension style- then lay on the floor till the until it feels safe to move, flavor of workout. Surge definitely helps.
Hallelujah to Surge. It does exactly what it says it does, it totally glides you through the brutal workouts. My endurance went up at least 40%. My reps went up at least 35%. No heebie jeebies or upset stomach either. This IS an AMAZING product. This product is NOT a joke, it works.
