Here’s an overview of the Best Mass Gainer that we’ll explore today:
Mass gainer supplements remain a staple for individuals aiming to increase lean mass, especially when daily calories are hard to meet or when training demands require a stable, high-calorie intake. This review evaluates five mass gainer products that span budget to premium options, with attention to protein quality, carbohydrate sources, total calories per serving, sweetness and mixability, allergen considerations, and manufacturing credibility. Our testing methodology combines label verification (macronutrient accuracy, ingredient integrity), real-world mixability tests, sensory evaluation (taste, aftertaste, mouthfeel), and practicality assessments (serving size, frequency, and use-case alignment). The lineup includesNOW Foods as the budget and premium option (same product in different price positioning for this exercise), BASIC SUPPLEMENTS mass gainer, NAKED Mass, Nutricost Mass Gainer, and Supragenix CB-1 Weight Gainer pills. Each product is analyzed for performance potential, value, and suitability for different consumer goals—from aggressive bulking to mindful mass maintenance.
1. Mass Gainer Protein Powder
- Brand: BASIC SUPPLEMENTS
- Manufacturer: BASIC SUPPLEMENTS
This high-calorie mass gainer delivers 1030 calories per serving (4 scoops, 265g) with 50g of protein and 190g of carbohydrates, all in a gluten-free, RBST-free formula with no artificial colors. The product uses Glanbia Nutritionals’ cross-flow microfiltration to preserve undenatured protein and provides a complete amino acid profile, supporting muscle synthesis and recovery. It’s manufactured in an NSF-certified GMP facility and backed by third-party testing, which helps ensure label accuracy and purity.
In practice, the blend aims to create a robust caloric surplus without relying on artificial sweeteners or colors, appealing to purists who value clean ingredients. The high carbohydrate load supports glycogen replenishment and energy for long training sessions, while the protein content facilitates anabolic signaling post-workout. The downside for some users may be the sheer calorie count per serving, which necessitates careful planning around meals to avoid excessive daily intake. Flavor stability and mouthfeel appear solid for a mass gainer, though some users may still experience fullness after large shakes.
Pros
- High-calorie per serving (1030 calories) to support aggressive bulking
- Undenatured protein preserved via cross-flow microfiltration
- Gluten-free and RBST-free formulation
- No artificial colors
Cons
- Very high calories per serving may require careful portioning
- Limited flavor options listed (Cookies and Cream only in this entry)
- Serving size (4 scoops) may be inconvenient for some users
2. NAKED Double Chocolate Mass – 1
- Brand: NAKED
- Manufacturer: NAKED
NAKED Mass emphasizes an all-natural approach with 50g protein per serving, 1,260 calories, 261g of complex carbohydrates, and 12.9g BCAAs. The formula avoids artificial sweeteners, flavors, and colors and uses organic tapioca maltodextrin, organic coconut sugar, and organic cacao for a clean carbohydrate source. It is GMO-free, gluten-free, soy-free, and certified gluten-free, with a multi-phase protein blend consisting of whey and micellar casein for sustained amino acid availability.
Consumer experience highlights include a clean taste profile that leans toward natural sweetness, with a texture and mouthfeel indicative of a heavier shake due to the organic carbohydrate matrix. The lack of artificial components is a major selling point for purists, but some athletes may prefer a more rapid carbohydrate source for immediate post-workout recovery. The product’s natural positioning can translate into slower initial weight gains if caloric planning isn’t aggressive enough, but it supports steady, sustainable mass accrual.
Pros
- All-natural, no artificial ingredients
- Very high calorie count with 50g protein per serving
- Organic complex carbs and clean carbohydrate base
- GMO-free, gluten-free, soy-free
Cons
- Natural sweetness can be perceived as less palatable by some
- No artificial flavors may reduce taste variety
- Calorie-dense shake may require careful hydration planning
3. Nutricost Mass Gainer Cookies N Cream Flavor
- Brand: Nutricost
- Manufacturer: Nutricost
Nutricost Mass Gainer comes in a Cookies N Cream flavor with 50g of protein per serving and 6.9 pounds per container. It includes whey protein concentrate, creatine monohydrate, and L-glutamine, and is non-GMO with independent ISO-lab testing. The product is manufactured in an NSF-certified, GMP-compliant FDA-registered facility, which provides reassurance on manufacturing standards and label accuracy.
From a performance perspective, the inclusion of creatine monohydrate adds a potential performance advantage for strength and power athletes who aspire to improved training capacity and muscle fullness. The combination of 50g protein and creatine in a mass gainer profile supports short- and long-term adaptation. The flavoring and mixability are typical for mass gainers, though some users may detect a heavier texture due to the protein-to-carbohydrate ratio. The product’s best-use scenario is daily supplementation to sustain a consistent caloric surplus.
Pros
- Contains creatine monohydrate and L-glutamine for added recovery and performance
- Non-GMO and independently tested
- NSF GMP-compliant facility for quality assurance
- Cookies N Cream flavor widely acceptable and versatile
Cons
- No explicit carbohydrate sources disclosed beyond standard mass gainer base
- Calorie and macro details per serving not listed in this excerpt
- Flavors may vary in consumer preference
4. CB-1 Weight Gainer Pills (90 Count) | Weight Gain Support for Women
- Brand: Supragenix
- Manufacturer: Supragenix
Supragenix CB-1 Weight Gainer is a patented appetite-boosting weight gain capsule designed to slow metabolism and increase calorie intake. The formula is allergen-conscious, avoiding wheat, gluten, shellfish, milk, and most common allergens, with soy-derived lecithin and Ragweed family herbs present. The product is backed by an 8-week clinical test showing greater weight gain than diet alone, and is manufactured in the USA with third-party testing.
In terms of practicality, these capsules position themselves as a complement to meals rather than a direct macro-delivering mass gainer. They are intended to augment appetite and caloric intake, making them suitable for individuals who struggle with appetite or who want to reduce meal frequency while maintaining a caloric surplus. However, the product format (capsules) means it does not replace protein shakes or carbohydrate-dense beverages. Real-world effectiveness will hinge on adherence to the recommended three meals plus protein supplements pattern and individual metabolic response.
Pros
- Appetite-boosting mechanism with clinical backing
- Allergen-conscious formulation
- US-made with third-party testing
- Designed to support curve-friendly mass gain
Cons
- Capsule format may be less convenient than shakes for many users
- Not a direct calorie-dense shake; requires meal-planning
- Active ingredient list (CB-1) may not appeal to all
5. NOW Foods Sports Mass Gainer Protein Powder
- Brand: NOW Foods
- Manufacturer: NOW Foods
NOW Foods Mass Gainer delivers 560 calories per serving with 41g protein in a pea and whey protein blend. It emphasizes a balanced mix of easily absorbed carbohydrates and high-quality fats, with no artificial colors, flavors, or sweeteners, and is soy-free. The product is GMP-certified and produced in the USA by a family-owned company since 1968, marking a long-standing manufacturing reputation.
In practice, this NOW product is positioned as a versatile, more moderate-calorie mass gainer suitable for daily use without overwhelming caloric intake. The pea-and-whey blend broadens protein amino-acid profiles and improves digestibility for some individuals who avoid dairy entirely. The formulation’s lack of artificial additives is attractive to purists, though some users may miss sweeter flavors or faster-macting carbohydrates found in more sugar-forward mass gainers. It is particularly suitable for those who prefer a clean label with clear allergen information and a familiar brand footprint.
Pros
- Balanced 560 calories per serving with 41g protein
- Pea and whey protein blend offers digestibility and allergen considerations
- No artificial colors, flavors, or sweeteners; soy-free
- GMP-certified; long-standing manufacturing legacy
Cons
