I like it! *by on Reviewed in the United Kingdom 26 January 2020* 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! ### ⭐⭐⭐⭐⭐ Quantity and taste. *by on Reviewed in the United Kingdom 9 July 2026* 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 ### ⭐⭐⭐⭐ Good value and lots of it *by on Reviewed in the United Kingdom 10 March 2026* Good value for the size of the tub (5kg). The flavour was pretty good and it dissolved and mixed fairly well and did not taste gritty like some. It could be added to water, milk or even coffee and tasted fine. Scoop was provided. ## Frequently Bought Together - The Bulk Protein Company, SERIOUS GAINZ - Whey Protein Powder - Weight Gain, Mass Gainer - 30g Protein Powders (Chocolate, 5kg) - Warrior Protein Shaker Bottle, Includes Wire Mixball Blender – 600ml – Perfect for Mixing Powdered Shakes, Clear, BPA Free, Dishwasher Safe - Warrior Creatine Monohydrate Powder – Micronised for Easy Mixing and Consumption – Proven to Improve Physical Performance / Recovery, 5g Servings (Unflavoured, 300g) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/68439111-serious-gainz-bulk-mass-gainer-protein-powder-5kg-weight-gain](https://www.desertcart.us/products/68439111-serious-gainz-bulk-mass-gainer-protein-powder-5kg-weight-gain) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-16*
