THP Mass Gainer, 30g Protein and 5g Creatine Per Serving in an All-In-One Formula

The Health Project Mass Gainer 2kg is an all-in-one mass gaining powder delivering 30g of protein, 23.4g of carbohydrates, 5g of creatine monohydrate, L-glutamine, HMB (calcium beta-hydroxy beta-methylbutyrate), L-leucine, taurine, MCT powder, magnesium, zinc, riboflavin, B6 and folic acid per 30g serving at 241 calories.

The protein comes from a blend of whey concentrate and whey isolate, providing a dual-speed absorption profile. The carbohydrate blend uses maltodextrin and fine oat powder for sustained energy release. The 5g creatine dose covers your full daily maintenance amount, meaning you do not need a separate creatine supplement. L-leucine is the key branched-chain amino acid for triggering muscle protein synthesis, and HMB supports muscle tissue preservation during intensive training periods.

The tub provides 66 servings across 6 flavours including Chocolate, Vanilla, Banana Pudding, Salted Caramel, Cookies and Cream and Forest Berries. Mix one scoop with 200 to 300ml of water or milk. Using milk adds extra calories and protein, which can help if your goal is maximum calorie intake. For higher-calorie shakes, blend with oats, banana and peanut butter.

This mass gainer suits hard gainers, people in a bulking phase and anyone who struggles to eat enough calories from food alone. It is more of a complete formula than a simple protein powder, so it works as a meal replacement or a substantial post-workout shake. If you are focused on leaner muscle gain with lower calories, the THP Ultimate Whey Protein at 109 calories per serving is a better fit.

Frequently Asked Questions

What makes THP Mass Gainer different from a regular protein powder?

THP Mass Gainer is an all-in-one formula with 30g protein, 23.4g carbs, 5g creatine, glutamine, HMB, leucine and taurine at 241 calories per serving. A regular whey protein like THP Ultimate Whey delivers 21.3g protein at 109 calories without the carbs, creatine or extras. Mass Gainer is designed for gaining weight, while whey protein is for lean protein supplementation.

Does THP Mass Gainer replace the need for separate creatine?

Yes. Each serving includes 5g of creatine monohydrate, which is the standard daily maintenance dose. If you take one serving of Mass Gainer daily, your creatine needs are covered. On days when you skip the mass gainer, you may want to take a separate creatine scoop to maintain daily consistency.

How many calories can I get from one Mass Gainer shake?

One scoop with water gives 241 calories. Mixed with 300ml of whole milk, that rises to roughly 430 calories. You can further increase this by blending in a banana (100 calories), a tablespoon of peanut butter (100 calories) and oats (150 calories per 40g). That turns one shake into a 780-calorie meal, which is practical for people who find eating enough solid food difficult.
