The part of our mission is to help active individuals better understand OPTIMUM NUTRITION products. Now choosing the right product for you is easier with more visible product benefits, features and flavours on each tub. **Q: The tub is not full to the brim when opened, why is that?** A: This is completely normal and is to do with the way the powder is vacuum packed into the tub. The powder settles over time. This does not impact the weight or number of servings listed on the label. **Q: What is the best way to prepare Serious Mass drink?** A: To get the optimal consistency and prepare your drink in easy and convenient way, we recommend using a blender. For optimal use, follow serving instructions on pack. **Q: Are the ingredients tested and safe?** A: All of the ingredients in our products have been approved and considered safe for consumption by the European Food Safety Authority. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***I on 16 March 2026* ### ⭐⭐⭐⭐⭐ Review *by D***C on 23 March 2026* ### ⭐⭐⭐⭐⭐ Review *by S***S on 30 October 2025* ## Frequently Bought Together - Optimum Nutrition Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Banana, 12 Pound (Packaging May Vary) - Optimum Nutrition Micronized Creatine Monohydrate Powder, Unflavored, 120 Servings, 600 Grams (Packaging May Vary) - VELOMIX -2 Pack- 28 oz Protein Shaker Bottles for Protein Mixes - 2x Wire Whisk | Leak Proof Shaker Cups for Protein Shakes | Protein Shaker Bottle Pack | Shakers for Protein Shakes-Black&Transparent --- ## 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.vu/products/743448962-optimum-nutrition-serious-mass-protein-powder-high-calorie-mass-gainer](https://www.desertcart.vu/products/743448962-optimum-nutrition-serious-mass-protein-powder-high-calorie-mass-gainer) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
