No proprietary blends. All the ingredients and amounts are on the label. He’s done the research and explains why each ingredient is used and the reasons for the amount of each ingredient. I really love that it has citruline instead of the arginine most pre workouts use because it can be absorbed in your system on a full or empty stomach. I definitely prefer the rainbow sherbet flavor. It doesn’t taste great, but it’s not bad. It definitely helps to mix it up a good 10 minutes before you drink it, and don’t chug it. I drink it over 20-30 minutes to prevent upset stomach. Sounds like a hassle but it is worth it. No jitters, no tingly niacin, just clean energy and quality creatine. This stuff is worth every penny. It works. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/366736255-jym-supplement-science-pre-jym-rainbow-sherbet-30-servings-rainbow](https://www.desertcart.sg/products/366736255-jym-supplement-science-pre-jym-rainbow-sherbet-30-servings-rainbow) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-24*
