Being a passionate cyclist, I have experimented with various hydration mixes such as Heed, Gatorade, and others, but I always found them too heavy, overly sweet, and not very effective. However, after using EFS consistently for the past month during over 15 rides, I have noticed a significant improvement.
While I never struggled much with cramping, I used to get extremely dehydrated despite drinking a full water bottle every 30 minutes. Since switching to EFS (just one scoop), I no longer…

After being a loyal Gatorade user for a long time, I came across this product and was impressed. I appreciate that it contains less sugar while providing the necessary electrolytes and energy for my long runs. Typically running 15 miles, I find this product keeps me feeling refreshed, prevents lactic acid build-up, and has a pleasant taste without being overly sweet or strong. It’s definitely a great option for endurance workouts.

After trying various sports drinks like Infinit, Accelerade, Gatorade, Hammer, and Powerade, I have found EFS to be the best fit for me. Unlike the others that felt thick in my stomach or caused discomfort like nausea or gas, EFS is light, easy to digest, and provides the energy and fuel I need to push myself harder during workouts. I have experienced fewer cramps, which is a major concern during intense rides or run days. The orange flavor is not only more enjoyable but also tastes better…

I have tried various pre-ride products for better performance as an avid mountain biker since 1990. Among them, EFS stands out for its effectiveness in preventing cramps and providing long-lasting endurance. It has a decent taste, no food coloring, is cost-effective, and mixes well. Before discovering EFS, I often struggled with brutal cramps, especially after a night of partying, leading to some unfortunate incidents on the trail. With EFS, I no longer have to worry about cramps ruining my…

This product is perfect for golfers! As a professional golfer, I have found it to be the ideal solution for staying hydrated throughout the day. Staying hydrated during rounds is crucial for maintaining peak performance, and this product has helped me feel refreshed, energized, and free from headaches. I particularly enjoy the flavor, with the Orange being my favorite due to its clean taste without any undesirable aftertaste. While the Lemon flavor required some adjustment, I found that…

I have been a long-time user of Ultragen, and I found that the Liquid Shots from First Endurance were a game-changer during a recent significant cycling event. I decided to switch to EFS after experiencing occasional cramping due to electrolyte and hydration issues. On my first ride with EFS, a challenging 120-mile journey with 14,000 feet of climbing and high temperatures, I had no issues. EFS provided the necessary amino acids for protein without the need for solid food, making it a…

The ordering process was simple and the product arrived promptly. While I typically enjoy other flavors of EFS, I found the orange flavor to be unappealing and it didn’t dissolve as well as the other varieties.

I recently participated in my first 24-hour bike race and relied on EFS for both training and during the event. This product was absolutely amazing. While others around me were struggling with dehydration and fatigue, EFS helped me maintain my performance throughout the race. The race kicked off at 7pm with temperatures dropping to about 55 degrees at night. The only issue I encountered was a slight stomach ache from possibly consuming too concentrated a mix during the night. Diluting it to…
