  6. Perfect Mass Gainer!

    Verified Buyer posted

    I have tried a few different mass gain protein supplements and this one is fantastic. Great ratio of carbs, protein and fat which really helps to put on lean muscle. Tried both the chocolate and french vanilla flavors, both are delicious.
    Great product and service from uprotein, next day delivery and answered my email questions within 30 minutes!

  7. protein shake

    Such a great price! And fast delivery! French vanilla taste and smell very good! Very smooth too, haven't tried fruit punch yet! Can't wait though

  8. Best I've tried. Nice work.

    Verified Buyer posted

    This is my third brand of protein I've tried. And I think I've found a winner. Mixes well, great choc flavour (seems to be dark chocolate as it's pretty rich), and the price for the quality is awesome. Packing is sleek and the zip luck is very secure. First time I've taken a separate BCAA supplement. It's working great.

  9. Great results

    Verified Buyer posted

    Have been using the mass builder for 3 months with great results

Great taste in the fruit punch mass gainers, creatine and BCAA working great, seeing results already 2 weeks and im up 3.4kg no fat and no bloated look what so ever. already recommended to 3 of my friends and happy to refer to more!!! A+++++ for this brand

  14. Another great product

    Verified Buyer posted

    Fantastic product at a even more amazing price, Keep up the good work Uprotein

  15. Excellent Value!

    Verified Buyer posted

    I ordered 12kg of protein for UProtein. I could easily talk about how cheap it was, because I got 12kg of protein for around $200 (with creatine and BCAA added in there also). However, the quality of the protein is fantastic. Since I got a mass gainer, there was a high amount of protein and carbs in each serving, which is exactly what I was looking for. I will be getting all my supplements from UProtein from now on. Excellent protein at an excellent price!

  16. Awesome Mass Gainer

    Verified Buyer posted

    Awesome mass gainer, high quality protein, mixes really well, tastes fantastic and even better price as a body builder i need a mass gainer that will give me lean muscle mass without adding any fat. This is a high quality mass gainer and with less sugar than most mass gainers its even better. It is a big part of my supplement stacks.
