Review: Great value gainer. I like it! - I've been using this for about 3 weeks now and really like it. It's cheap, decent quality, and does the job. The tub was fully sealed unlike some reviewers. I bought the chocolate flavour. It's actually quite nice and a lot better tasting than most powder shakes. Not sure how those who are complaining about the poor mixing are blending theirs, but I use my Nutri Ninja blender and it mixes great. If you don't drink it fairly quickly you do get a little sediment at the bottom (and I mean a little) but a few swirls of your drink container and it's fine. It's easy to get down. I weighed it out and find 4 flat scoops in 500ml of water gives you the 125g you need for 468 calories and 30g of protein. If you wanted to to use 500ml of whole milk instead then that's going to give you an additional (approx.) 300 calories and 17g of protein. So it really depends on how many surplus calories you're needing to start gaining. I've been doing a lot of cardio recently so I have found this gainer actually just keeps my weight consistant - which is great. I know if I wasn't doing cardio then I would definitely have gained weight. I currently have one shake a day but I may increase that to two soon. I expect to see a gain then (will let you know). Remember that this is a food supplement to add surplus calories and protein to your diet. Not some miracle powder. It does what its designed to do. Bar that, I've experienced no ill side effects. No bloating or excessive gas. So no complaints from the other half. If I suddenly go blind or grow an extra testicle in a few weeks I'll let you know. All in all I'm happy with it and think it's great value. I'll definitely be buying another tub!
Review: Quantity and taste. - Give star because the package was intact, no spill and not damage. Also because it’s really big. I just tried the chocolate flavour taste nothing like chocolate but I like it, I didn’t want an overpowering chocolate flavour anyways. The sim is to gain weight so fingers cross, also it’s really thickens when missed with water or any liquid omg 😦, I think it’s best to mix with a blender for best results . And I got a little extra creatine gift thanks

## Features

- HIGH-CALORIE MASS GAIN FORMULA WITH ~27G PROTEIN PER SERVING – SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus. Designed for hardgainers and anyone looking to increase size and strength, it supports muscle recovery, training performance and steady weight gain when combined with a structured nutrition plan.
- SUPPORTS MUSCLE GROWTH & POST-WORKOUT RECOVERY – Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein, whey isolate, casein and oat flour delivers both fast and sustained amino acid release, helping refuel muscles, restore glycogen levels, maintain a high daily protein intake and support performance between sessions.
- MIXES BEST WITH MILK FOR A SMOOTHER, MORE ENJOYABLE SHAKE – As a bulking protein powder, SERIOUS GAINZ can be prepared with water or milk, though many users prefer milk for a smoother, richer and more consistent texture. Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake that’s easier to drink during heavy bulking phases. This preparation method makes each serving more enjoyable and supports daily consistency as calorie needs increase.
- SMOOTH, SWEET FLAVOUR EXPERIENCE YOU CAN ENJOY DAILY – This whey protein powder delivers a rich, dessert-style taste that makes each protein shake enjoyable as part of your daily bulking routine. Available in popular flavours such as Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it offers options suited to both classic and dessert-style preferences. Whether you mix it with water or milk, or blend it into oats and smoothies, the flavour stays satisfying across long bulking phases.
- FILLING FORMULA DESIGNED TO HELP MAINTAIN A DAILY CALORIE SURPLUS – This mass gainer delivers a dense, satisfying shake that helps men and women stay on track with daily calorie targets during bulking phases. Its naturally filling consistency supports a sustained surplus, while starting with smaller servings, adding more liquid or spacing intake can help maintain comfortable, consistent nutrition throughout the day.

### ⭐⭐⭐⭐ Great for muscle growth, but with A LOT of carbs.
*by B***L on 4 November 2025*

I started using this after a severe acute spinal condition and emergency spinal surgery left me with around a 17kg loss of lean muscle mass. Once I had a go-ahead to exercise safely, I got back to the gym and got into serious weight gain territory. After 3 months I had gained 7kg of visible lean muscle. I’m 66 years old, so wasn’t expecting any rapid gains. My gym routine and strength progressed rapidly, and the muscle growth continued, but I’ve noticed my body fat has also started to increase, so I’m switching to Serious Protein from here on out, to lower the level of carb I’m taking in. Sugar content in the ‘Gainz’ product is seriously high, and will add to your body tissue makeup, as it has with me. The whey protein route is widely accepted as great for muscle building support, and both products tick that box. Quality and flavour are faultless, although I suppose flavour is a very subjective topic. The powder mixes well with water or semi-skimmed milk (for extra protein) in any decent protein drink shaker. The lid seals very tight, so the contents stay fresh for as long as the 5kg lasts you. Recommended for weight gain, but might add to body fat more than you want.
