Eight products that made our shortlist after filtering across all 12 tracked US retailers. Click any pick to see live prices, all retailers, and the latest deal.
How We Ranked These
Ranked strictly by grams of protein per scoop, as listed on each product's Supplement Facts panel. Mass gainers dominate the top of this list since they pack 50g+ into a single double-scoop. Pure isolates with 30g doses round out the rest.
All prices verified within the last 24 hours. We re-check every product across all 12 tracked retailers (Walmart, Amazon, iHerb, GNC, Bodybuilding.com, Target, Vitacost, Muscle & Strength, Costco, Tiger Fitness, MyProtein, Transparent Labs) every two hours. Out-of-stock products are excluded from these rankings entirely.
Our Top Pick
7 lb · 63g protein/scoop · 14 servings
Mass gainers dominate this category for a reason: they're engineered to pack 50 to 63g of protein into a single shake. If you're a hard gainer or a heavy training athlete with calorie demands food can't meet, the top pick is built for you. See Amazon price →
Runner-Up
6 lb · 60g protein/scoop · 15 servings
Same mass-gainer category, slightly different formula. Worth checking if the top pick's flavor profile doesn't suit you. See Amazon price →

Mass gainers top the list. Muscletech Mass-Tech Extreme 2000 delivers 63g of protein in a double-scoop serving. Other mass gainers in the 50 to 60g range include Nutricost Mass Gainer, BSN True Mass 1200, and ON Serious Mass.
Only if you can't eat enough food. Mass gainers are calorie-dense (800 to 1200 per shake) and protein-dense, designed for hard gainers who struggle to hit a calorie surplus through whole food. If you're already eating enough, a regular whey blend at 24g per scoop is better.
Not at all. Studies on muscle protein synthesis suggest 0.4g/kg per meal is optimal for most lifters, which translates to 30 to 40g per shake for a 175 lb person. A 30g-per-scoop powder hits this efficiently in a single scoop.
Yes, and it's often cheaper. Two scoops of Body Fortress Super Advanced gives you 60g protein for under $1.50, vs $2 to $3 per serving for a dedicated mass gainer. The only reason to buy mass gainer specifically is if you also want the calorie-dense carb base.
Not directly. Protein quality is measured by amino acid completeness and digestion rate, not amount per scoop. A 30g whey isolate scoop and a 60g mass gainer scoop deliver functionally equivalent amino acids per gram. The difference is dosage and calories, not quality.
When used correctly, yes. The risk isn't the protein; it's the calorie surplus they create. If you drink a 1200-calorie shake on top of an already-adequate diet, you'll add fat as well as muscle. Use mass gainers as a tool to hit a calorie target, not as a free-for-all.
