The best of pre-workout for price and performance and tolerance.
I've taken many different pre-workouts over the last 20 years and the quality and performance are all over the board. My favorite for a long time was surprisingly, GNC LIT. Works great but is missing some elements I want. JYM has those and makes the difference. The biggest issue being creatine. LIT uses monohydrate while JYM uses the HCL version. Monohydrate requires loading and it takes a lot. It also causes bloating. HCL does neither. Immediate absorptio, no loading, no bloating. JYM has a blend that doesn't give you the jitters or crashing. It feels good and the workouts we do it is consistent with power and endurance. It's now the go to and the only one I buy. If you're new to it I would strongly suggest you try 1/2 scoop with 16oz or so. When we do indoor climbing we drink it as a pre and intra workout. Then finish with either a protein shake or BCAA/EAA post workout drink. If you're sensitive to caffeine then be careful. Full dose has 300mg of caffeine anhydrous (most do). Taken later in the day or evening may keep you awake. It doesn't bother us but it does for a number of people. You can find some pre's that do not have any caffeine. JYM is not one of them. Last, the flavor. We like them. Rainbow Sherbet and Pink Lemonade we both like. The Dark Cherry I like but wife not the biggest fan. She likes the Strawberry Pineapple. I'm not a fan. So we keep a couple of jugs to mix it up so it doesn't get boring. Price and performance. It's worth the price compared to any other pre I've used. Their quality and consistency is there and no side effects.

A Great Pre-Workout
Packs a powerful punch, delivering a burst of energy and focus to fuel your workouts. The rainbow sherbet flavor adds a refreshing twist to your pre-workout routine, making it a treat to look forward to before hitting the gym. With a blend of high-quality ingredients, including citrulline malate, beta-alanine, and caffeine, this supplement is designed to enhance performance and endurance. However, the only downside to Pre JYM Rainbow Sherbet is its price. While it undoubtedly delivers results, the cost can be prohibitive for some, especially considering the relatively small number of servings per container. Despite this drawback, many users find the benefits outweigh the expense, making it a worthwhile investment for serious athletes and fitness enthusiasts. Overall, this is a top-notch pre-workout option that delivers on its promises. If you're willing to splurge a bit for quality and performance, this supplement is sure to take your workouts to the next level.

Check your Expiration Dates
The product is good, its all my husband uses but the issue i have is they sent me something that expires Feb 2022. So this means this product was made years ago. My husband opened it, it was chalky and taste has faded. He didnt realize it until it was opened and used. Wherever this came from you need to watch expiration dates because this shouldnt of been sold to me
