Review: It helps a lot - Optimum Nutrition Serious Mass is a great choice for anyone looking to gain weight, build muscle, or increase overall calorie intake. The Chocolate flavor mixes smoothly—especially if you use a blender—and has a rich, dessert-like taste without being overly sweet. Each serving delivers a very high amount of calories, protein, and carbs, which makes it ideal for people with fast metabolisms or those who struggle to eat enough throughout the day. It also includes added vitamins, minerals, and creatine for extra support. The bag is large and lasts a good amount of time depending on how much you use. The powder is heavy, so mixing by hand can be a bit difficult, but blending solves that problem easily. Overall, Serious Mass is effective for healthy weight gain and muscle-building goals. If you need a calorie boost and don’t mind a thick shake, it’s a solid and reliable product.

I get sick to where I cant eat this helps me pull back the calories and rebuild my muscles quickly so I dont lose my progress. The taste is good and milky doesn't have soy (which im allergic to) which most proteins contain. There is a chocolate smell that is very pleasant. It dissolves without having to be blended and blends well in my shaker bottle. ## Frequently Bought Together - Optimum Nutrition Serious Mass, Weight Gainer Protein Powder with Creatine - Nutricost Creatine Monohydrate Micronized Powder 500G, 5000mg Per Serv (5g) - 100 Servings, 17.9 Oz - 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.com.kw/products/1047483-optimum-nutrition-serious-mass-weight-gainer-protein-powder-mass-gainer](https://www.desertcart.com.kw/products/1047483-optimum-nutrition-serious-mass-weight-gainer-protein-powder-mass-gainer) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
