Buying Guide: How to Choose Your Serious Mass
When selecting a weight gainer, it’s not just about grabbing the biggest tub. You need to consider your specific goals, dietary tolerances, and how the product fits into your daily routine. Here are key factors to evaluate:
Calorie and Macronutrient Profile
The entire point of a weight gainer is to provide a high number of calories in a convenient shake. Serious Mass packs a powerful punch with over 1,200 calories per serving. This is ideal for individuals who struggle to eat large quantities of food but need a significant surplus to gain weight.
Pay attention to the protein-to-carbohydrate ratio. With 50 grams of protein and over 250 grams of carbs per serving, this formula is designed to support muscle repair and replenish energy stores. This makes it an excellent choice for post-workout recovery or as a substantial meal replacement.
Flavor and Mixability
You’ll be drinking this shake regularly, so taste and texture matter. Serious Mass is available in classic Vanilla and rich Chocolate flavors. Both are known for being sweet and pleasant, but mixability can vary. Using a blender is recommended to avoid clumps and create a smoother, more enjoyable shake.
Don’t be afraid to get creative. Blend in a banana, a scoop of peanut butter, or some frozen berries to enhance the flavor and boost the nutritional value. This is a great way to keep your taste buds from getting bored during a long bulking phase.
Serving Size and Value
Serious Mass comes in various tub sizes, from a 3LB starter size to a massive 12LB economy option. The serving size is two scoops, which is a substantial amount of powder. If you’re new to weight gainers, starting with a smaller size is a smart way to ensure you enjoy it and can tolerate it before committing to a bulk purchase.
For those who are serious about gaining weight, the larger tubs offer more servings and a better value over the long term. Consider your budget and how quickly you plan to consume the product. If you’re consistent, a larger size is often the most economical choice. For more pre-workout options to pair with your mass gainer, check out our gorilla mode reviews for intense training sessions.
