Rainbow Sherbet flavor is a total knockout, my friends who tried mine said the same - they loved the flavor. Even when I dilute it into a larger volume of liquid like a 32 ounce bottle of water - it still tastes great. Tastes best ice cold, still tastes fine even when it warms up. I've bought it more than once during the last 5 years. No bad side effects, no gross aftertaste. If you don't want it to foam up at all when you shake it - just leave less air gap at the top of your bottle before closing the lid to shake it. Liquid mixes well usually a light pink color, after a couple minutes any foaming at top of the liquid vanishes. Liquid is thin, easy to drink, and not chalky tasting Review: Great flavor and it actually works. - Great flavor and it actually works. I take this daily, and it's a game changer. ## Features - HIGH PERFORMANCE PRE-WORKOUT POWDER: Pre JYM pre-workout formula features 14 research-backed ingredients for maximum energy support, endurance, & muscle pump performance for men & women - SUSTAINED ENERGY SUPPORT: Formulated with 300mg Caffeine, 6g Citrulline Malate, 500mg Beet Root Extract & 1.5g Betaine to support sustained energy without crashes or jitters during your gym workout - PROMOTES MENTAL FOCUS: Includes 1500mg L-Tyrosine, 150mg Alpha-GPC & 50mcg Huperzine A to support enhanced mental focus & drive so you can stay locked in and perform throughout every training session - SUGGESTED USE: Mix 1 scoop in 16-24 oz of water and drink 30-45 minutes before workouts.

I take this daily, and it's a game changer. ### ⭐⭐⭐⭐⭐ The best of pre-workout for price and performance and tolerance. *by G***M on July 4, 2025* 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. ## Frequently Bought Together - JYM Supplement Science Pre JYM Rainbow Sherbet Pre Workout Powder for Men & Women, BCAAs, Nootropics, Creatine HCI, Citrulline, Beta-Alanine, Betaine, Taurine, Huperzine, 30 Servings - JYM Supplement Science Post JYM Active Matrix Rainbow Sherbet Amino Recovery Powder Pure Creatine HCL, BCAA’s, Glutamine, Carnitine, Betaine, Taurine for Strength, Repair, Performance 30 Servings - ZMA JYM, Zinc & Magnesium Supplement - Zinc, Magnesium and Vitamin B6, YM Supplement Science, 90 Vegetarian Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/296237403-jym-pre-workout-rainbow-sherbet-creatine-hci-caffeine-28-6](https://www.desertcart.sc/products/296237403-jym-pre-workout-rainbow-sherbet-creatine-hci-caffeine-28-6) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-16*
