Review: One of the best post-workout recovery drinks I've used. - After a hard workout, a post-workout drink can be critical to recovery. The first thing you want to do is replace lost fluid. Secondly, you want to get some carbohydrates to restore lost glycogen. Finally, you want protein to rebuild muscle tissue that may have been damaged during your workout. The best way to do this, is with a sports drink that contains the optimal 4:1 carbohydrate to protein ratio. The makers of Endurox, Pacific Labs, were actually the ones to discover this over ten years ago, but independent research since that time (as well as my own results), seems to support this. Many sports/recovery drinks have adequate amounts of carbohydrates, but Endurox sets itself apart by adding protein to the mix. ALTERNATIVES One of the best alternatives is 1% chocolate milk. It's cheap, and provides the perfect balance of carbohydrates and protein. However, it has to be refrigerated, which isn't always practical for me. I'll also have periods where I abstain from dairy, and I don't want the additional saturated fat contained in milk. Another alternative is the P90X Results and Recovery Formula: 30-Day Supply, Tub by Beachbody. I think this is the best recovery formula out there and has the best ingredients, but it's just too expensive to be practical for me [Disclaimer: I am a Beachbody Independent Coach]. Pacific Labs also makes a product called Pacific Health Accelerade, Lemon Lime, Net Wt. 4.11 lb., 60 serving . I've seen a lot of confusion over the differences between Accelerade and R4. The main difference is that Accelerade is designed to fuel a workout, while Endurox is designed to help with recovery. As such, Accelerade contains electrolytes and more sugar (per quantity). I think Endurox is more effective as a recovery drink, but if needed, I think you can use these two products interchangeably without too much of a difference in results. HOW TO USE Don't take Endurox as a meal replacement. The high amounts of sugar will spike insulin levels and likely contribute to weight gain. Endurox should be consumed within a 20 minute window following vigorous exercise. If you take it as a pre-workout supplement, plan on consuming it about 20-30 minutes before you expect to need it. TASTE/CONSISTENCY One thing I like about Endurox is that it has a pleasing taste, which can be hard to find in a recovery drink. I think the best flavors, in order of preference, are Lemon-Lime, Chocolate, Orange, Fruit Punch, Vanilla (stay away from this flavor). The powder mixes very well with water and dissolves easily. RESULTS I have been using Endurox for about four years now and have had a lot of success with it. I cannot tell much of a difference in results with it versus the P90X formula, and both seem to work well in aiding recovery. In addition to using as a recovery drink, I will also sometimes use it as a pre-workout drink if I am out of Accelerade. A serving size is two scoops (270 calories), but for any workout under an hour, I will cut this in half. For runs longer than 8 miles, I take half a scoop combined with 1 scoop of BPI 1.M.R Fruit Punch, 224 grams right before my run, and follow the run with 1-2 scoops depending on length. I have found this incredibly effective on long runs, as well as the more strenuous Beachbody workouts, such as P90X Plyometrix and Insanity Plyometric Cardio Circuit. I also have noticeable results with decreased soreness when using Endurox when compared to water alone. There aren't too many workout supplements that give me as noticeable results as Endurox, and until something better (or cheaper) comes along, I'll continue to use it after every tough workout. I've uploaded nutritional information under customer images.
Review: Been using for years, great for soreness - I used Endurox R4 about 15 years ago under a recommendation by my former Olympian track coach. Back then, the taste was great and it did wonders to reduce muscular soreness and fatigue following hard workouts. I am glad to say today the taste is still great and its recovery effects are still going strong. These days, I mostly perform powerlifting-type training with some cardio on my off days and I take a scoop (half the recommended serving size) every once in a while when I've had a particularly hard workout and know I'll be feeling it the next day. I think it is worth mentioning that the scoops are large but it mixes very well in water. The sour flavors are great and chocolate is good as well, but I can't vouch for the other flavors. Overall a solid choice for recovery!

### ⭐⭐⭐⭐⭐ Something that Actually Works.
*by G***E on August 8, 2025*

I love this stuff. I'm just an old guy that runs marathons. I don't recover like I used to. I train, run long runs, speed work, hills, tempo, whatever my plan calls for. After a really hard effort 2 heaping scoops in 16oz of cold water in a shaker. Really helps recover for the next day's workout. I need all the help I can get. So many products make promises they just don't deliver on-I try them and then don't buy again. This stuff?-I have bought before and will buy more when I'm out.
