2. MuscleTech Mass Tech Extreme 2000: High-Calorie Bulking Power

MuscleTech Mass Tech Extreme 2000 delivers over 2,000 calories with substantial protein and high carbs in a single serving. This profile suits lifters who need aggressive bulking support and struggle to eat enough whole food.

The heavy carbohydrate content helps refill glycogen and supports insulin-driven nutrient uptake into muscle cells. Many coaches recommend this option for hardgainers who cannot consistently hit calorie targets with regular meals. Its amino acid profile supports both quick recovery and long-term strength and size gains.

3. Dymatize Super Mass Gainer: Calorie Support for Strength Gains

Dymatize Super Mass Gainer provides 1,280 calories, 52g protein, and 245g carbs with added BCAAs to support recovery. Many users see steady increases in muscle size and strength when they pair it with progressive overload.

The moderate calorie level works well for lifters who need a surplus but want to avoid feeling overly stuffed. Added branched-chain amino acids help support muscle protein synthesis during long or intense training sessions.

4. Optimum Nutrition Serious Mass: Long-Standing Bulking Classic

Optimum Nutrition Serious Mass offers 1,260 calories and 50g of protein for a reliable calorie surplus in advanced athletes. This long-running formula has supported transformations for decades.

The macro balance provides steady energy and supports muscle repair after heavy lifting. Some users experience bloating from the maltodextrin content, so proper hydration and timing around workouts can improve comfort and digestion.

5. Transparent Labs Mass Gainer: Clean-Label Mass Support

Transparent Labs Mass Gainer offers around 750 calories per serving with high-quality ingredients and clear labeling, including creatine monohydrate. The formula supports lean gains while helping limit unnecessary fat.

Digestive enzymes in the blend help reduce the gas and bloating that often come with high-calorie shakes. The clean ingredient list appeals to lifters who care about both performance and overall health, not just maximum calories.

High-Calorie Shake Ideas for Skinny Guys at 150–170lbs

Skinny lifters who have dropped heavy “bloat-bomb” gainers can still gain size by stacking smart calories with creatine. Effective mass gain at 150–170lbs usually requires high-calorie shakes plus performance ingredients that support nutrient use and muscle protein synthesis.

For 150–170lb lifters, strategic timing often includes half-servings on rest days to keep nutrients flowing without stressing digestion. Lucas reported better digestion and steady gains by using half scoops mid-morning and at night on off days.

Why Creatine Stacking Makes Mass Gainers More Effective

Creatine supplementation amplifies the impact of mass gainers by supporting strength, performance, and recovery. Creatine monohydrate increases ATP regeneration capacity, which lets you push harder and recover faster between sets.

Bucked Up offers several creatine options, including Six Point Creatine (multi-form blend), Pure Creatine (micronized monohydrate), and convenient formats like Creatine Gummies and Creatine Candy. All Bulk No Bloat already includes creatine, so many users do not need a separate creatine powder with that product.

Traditional mass gainers focus mainly on calories, while Bucked Up products highlight performance compounds that directly support training output. Many lifters report gaining about 10lbs of lean mass in 2 months when they combine structured nutrition with consistent creatine use. NSF Sport certification supports purity and potency for athletes who compete.

Creatine and high-quality protein work together to create a strong environment for muscle growth. Mixing creatine with a mass gainer after training supports faster recovery and lean growth, as shown by users who moved from 76kg to 83.5kg in 10 weeks with limited fat gain.

Mass Gainer FAQs for Real-World Bulking

What is the healthiest mass gainer?

Bucked Up All Bulk No Bloat offers a very health-focused approach by delivering clinically dosed muscle-building ingredients without extra calories that often turn into fat. The zero-calorie formula includes 5,000mg creatine monohydrate, 3,000mg HMB, 5,000mg L-glutamine, and 250mg Mediator Phosphatidic Acid to support protein synthesis. This setup lets you control calories precisely while still driving anabolic signaling with science-backed ingredients from NSF-certified facilities.

Do mass gainers work for going from 150lb to 170lb?

Mass gainers can support a jump from 150lb to 170lb when you pair them with progressive resistance training and smart timing. The main requirement is a consistent calorie surplus with enough protein and performance ingredients to support training. Many lifters in this range need 1,000+ calorie shakes plus whole foods to reach 3,000+ daily calories for lean growth. Choosing formulas with digestive enzymes and stacking creatine often improves both comfort and results.

Which mass gainers do not cause bloating?

Lower-bloat mass gainers avoid cheap fillers like maltodextrin and include digestive enzymes to support digestion. Bucked Up All Bulk No Bloat reduces bloating risk through its zero-calorie design while still delivering muscle-supporting compounds. Creatine HCl options, such as Bucked Up capsules, absorb quickly and support cellular uptake with less water retention. Helpful strategies include gradual dosing, drinking 3–4 liters of water daily, and choosing isolate-based proteins if you are sensitive to lactose.

How much creatine should I take with mass gainers?

A daily creatine dose of 3–5g works well when you stack it with mass gainers. Bucked Up All Bulk No Bloat already includes 5,000mg creatine monohydrate per serving, so you usually do not need extra creatine with it. For other mass gainers, add 5g Bucked Up Pure Creatine or Six Point Creatine after your workout to support ATP regeneration and muscle protein synthesis. Take creatine every day to maintain saturation and support strength and recovery on both training and rest days.

What is the best timing for mass gainer consumption?

Post-workout and before bed are two of the most effective times for mass gainer shakes. Many advanced lifters also use split dosing, such as half-servings mid-morning and evening on rest days, to keep nutrients steady without upsetting digestion. Bucked Up All Bulk No Bloat works well on an empty stomach about 60 minutes before training or before bed to support absorption of its performance compounds. This timing approach keeps your body in a more consistent muscle-building state while reducing discomfort from huge single servings.
