Tastes great & price is right. ### ⭐⭐⭐⭐⭐ Great price for the size *by on Reviewed in the United Kingdom 2 April 2025* Nice tasting protein power. It states to mix with water on the pack but don’t taste great that way so I use skimmed milk instead as then taste more like a milk shake and you still get the benefit of the product and will continue to use it.Great sized tub for the price and lasts for weeks ### ⭐⭐⭐⭐ would def buy again (banana) (not white chocolate) *by on Reviewed in the United Kingdom 1 April 2018* i bought the banana and white chocolate. i personaly like the flavour of banana and would most likely buy it again but next i will buy another flavour to just test the favours. white chocolate personaly just does not taste that good, its not bad but its not good. really does not taste much like white chocolate but its fine. white chocolate bucket came a lot fuller than the banana not sure what it was. mixability is not the best as if u let it sit u get bits at the bottom so i shake it up and then drink a lot and when i go to drink it again i shake it up so the stuff is throught the whole drink.there is never any lumps tho is which is good.i personally like to drink big protein shakes so taste needs to be nice and the favlours are good. the serving size of 3 scopes makes the protein shake good and so after drinking i feel full which is very nice and i would def recommend buying this as it is super cheap ## Frequently Bought Together - The Bulk Protein Company - Serious Gainz – Mass Gainer Protein Powder – Banana 5kg, B142-BA - 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.gr/products/47931359-serious-gainz-5kg-40-servings-vegetarian-mass-gainer-protein-powder](https://www.desertcart.gr/products/47931359-serious-gainz-5kg-40-servings-vegetarian-mass-gainer-protein-powder) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-16*
