Optimum Nutrition Serious Mass, Weight Gainer Protein Powder for Muscle Gain, Added Immune Support, Chocolate Peanut Butter, 12 Pound (Packaging May Vary)

Ottimi effetti e gusto davvero piacevole. Richiede un po’ più tempo per sciogliersi in acqua, ma le porzioni sono abbondanti e soddisfacenti.

Es de muy buena calidad y precio

Like the flavour.

Serious Mass really lives up to its name. If you’re looking to put on size, this is one of the easiest ways to get a huge calorie and protein boost in one shake.. The taste is solid (I’ve tried Chocolate and Vanilla), though it’s definitely thick — I usually blend mine with milk or add a banana/peanut butter to make it smoother. It’s filling, so I don’t use it every day, but on heavy training days it’s perfect. The bag is big and lasts a while, though it can be a bit pricey. Overall, a great option if you’re serious about bulking and need extra calories.

Llevo tiempo utilizándola y me parece la mejor
