⭐⭐⭐⭐⭐ Built Like a Truck, But Tastes Like DessertI’ve been lifting consistently for five years and always struggled to put on mass without feeling like I was force-feeding myself chicken and rice five times a day. Enter Rule One Mass Gainer—aka my new best friend disguised as a chocolate fudge milkshake.Let’s start with the calories: 1,220 per serving. That’s not a typo. That’s practically a cheat meal disguised as a supplement. I went from “lean and lanky” to “bro, you bulkin’?” in under a month. My mom even asked if I was hiding something under my hoodie (it was just new traps).The protein-to-carb ratio is what makes this stand out. 40g of high-quality whey per serving with over 250g of complex carbs means it’s not just sugar-packed fluff. It doesn’t spike my blood sugar like some other gainers I’ve tried, and I don’t crash after drinking it. No weird bloat, no bathroom emergencies either (you know the ones).Mixability? Pretty solid for such a dense formula. I use a blender—shaker bottle doesn’t cut it unless you enjoy clumps and arm day at the same time. It’s thick, but that’s expected. I throw in some peanut butter and a banana sometimes, and it feels like I’m drinking a five-star dessert that’s somehow good for my gains.Flavor – Chocolate Fudge is rich, but not overly sweet. Tastes closer to a brownie batter than any “protein powder” I’ve ever had. I’m actually surprised they didn’t mess this up. I’ve had proteins that taste like regret. This one tastes like victory.Downside? You only get 8 servings per tub. That’s a week if you’re doing one a day. But if you want quality calories and serious weight gain without scarfing down six meals a day, this is your go-to.Effectiveness:Noticeable Gains, Minimal FluffI started using this as a hard gainer stuck at 162 lbs for months. After two weeks of consistent training and taking 1 serving daily post-workout, I was up to 168 lbs—not water weight or just fat either. My shirts fit tighter in the shoulders, my lifts started creeping up (deadlift up 15 lbs, bench up 10), and people at the gym noticed. That's saying something.This mass gainer isn’t just tossing sugar at your body and calling it “bulk.” The 40g of all-whey protein helps with legit muscle recovery, and the 250g+ of carbs give you real fuel for intense training sessions and replenishment afterward.I felt less sore between workouts and had more energy, which helped me push harder in the gym. I also didn’t feel sluggish or overly full after drinking it—more like fueled. If you train hard and eat decently alongside this, it will work. If you don’t train, you’ll still gain... just probably not where you want it.

Best in this price.
Taste is fair, easy mix either no lumps, taste is fine, not too sweet, it suggest 2 scoop per serving that’s makes it more sweet. The scoop size is pretty big, i take one scoop in morning and one in night. But quality is good, and per price that’s the best mass gainer with enough calories as per need .

It’s tastes like Nutrament
Honestly one of the best shakes ever, mixes great in a blender and specially if you have common sense and blend two scoops at a time. Make a shake then fill water bottles up with it drink the serving through the day and your waist of small Seville you’re muscles grow.

Good Stuff!
The thickness is better than most. Texture is great mixes easily especially on the go. We all need protein, this is a great option for the price point!

Lumpy
Won't mix no matter how long you try. Even using a shaker I couldn't get the lumps out.The taste was OK when I tried drinking around the lumps. I ended up throwing away the whole container.

Si quieres algo con poca azucar y aun asi con muy bueno sabor te lo recomiendo!
The media could not be loaded. Generalmente no dejo reseñas pero siento que es muy necesario en este caso y sere bastante sincero! Llevo años tomando suplementos de muchas marcas diferentes y reconocidas en la industria pero todas ABSOLUTAMENTE TODAS ME CAUSAN GRANOS EN MI CARA al siguiente dia despues de tomarme el batido pero con este batido es totalmente diferente y la verdad estaba escéptico con la marca porque no es conocida al menos yo no la habia visto pero estaba tan cansado de probar marcas incluso costosas que deje de guiarme por las marcas “tendencias” y comence a buscar ganadores de peso pero con la menor cantidad posible de azucar (algo que si quieres un ganador de peso Bulking sabes que es muy dificil de conseguir) y la verdad con este suplemento no he tenido mas problemas! Sabe muy bien el sabor no es empalagoso y no se siente quimico ni generico la verdad es un sabor tan agradable que no te cuesta para nada digerirlo y son solo 2 scoop a diferencias de otras marcas que tienes que echarle hasta 4 scoop para llegar a las misma calorias de lo que tiene este lo cual se agradece muchísimo y cae muy bien en el estomago sin ser extremadamente pesado! 💯 RECOMENDABLE si buscas un ganador de peso pero sin tantas azucares ni azucar añadidas te recomiendo definitivamente la marca 1 RULE MASS GAINER definitivamente lo volvere a comprar luego de que se me termine.🌟
