    Great taste

    This tastes just like banana funny enough but real banana not a flavour. Awesome for my oats mix. An amazing breakfast with the banana protein
  • Margaret Gardiner
    Taste is very nice and easy to use. Very quick delivery too
  • Latifah Lea
    It doesn't taste very nice with Walter so if decided to make It with milk hopefully be better but I love the product I also have the vanilla one which is amazing I need a new on tbh thank you.

  • Customer862
    Great flavour, actually look forward to my morning shake.
  • Kerry Dolan
    Think thus whey powder is really good and importantly the flavour is great
  • Christopher Kit
    Sits in mid range imo. It’s quick a thick shake and the taste is quite reasonable. Tasted better and also tasted far worse. I’d get it again if on offer
  • Amory Thomas
    This really does have excellent flavour in comparison to any other similar product I have tried. Great chocolate flavour. I especially like it made thick so it only just pours! Am happy with the efficacy of the product in building/retaining lean muscle. Great after a workout when I don't want a lot of solid food. Sometimes blend with Diet Whey Lean.
  • Barbara Carmichael
    Great taste. Very chocolatey. Easy to mix , with milk or water
  • Amer Janjua
    I like the consistency of this powder, smooth and thick. Perfect for making high protein desserts.

    I've never been a fan of whey protein drinks but this one is really good. I add spinach and frozen berries but even without these the taste is really good. There was a great intro. offer too and delivery was super fast. Would definitely recommend.

    Good taste (a bit sweet though) but i do find it difficult to get it smooth

    Good healthy alternative to chocolate or sweets and helps cravings
  • Greg
    Chocolate mint is my favourite so far, closely followed by cookies and cream. I really want to try out the birthday cake flavour next!! The phd diet whey is the best I’ve found, tastes great and less than 200cals for over 30grams of protein it can’t be beat.

    Great flavour and a very satisfying thick shake that fills me right up. Plus try 1 scoop of salted caramel and a scoop of chocolate peanut and it tastes like a snickers lol
  • Avril
    The PHD salted caramel is incredible. The taste is amazing and just satisfies the sweet craving. A must try. I always look forward to my PHD after training

  • Avril
    PHD shakes are amazing. My treat for when I finish training
  • M Stone
    Mixes really well without clumping, not the best tasting. I could taste coffee but that could be just me!
  • Miss Mikhaila Faries
    I am really not a fan of the texture of this protein. I’ve used it once and won’t use it again.
  • customer
    Taste is good, not powdery and doesn’t have that harsh protein taste some powders have. However isnt very peanutty, found it to be more of a chocolate flavour. Great protein content with low calories and sugar, would buy again.
  • Jacqui
    Quite a delicate taste, I would prefer a bit more. Makes a good thick shake
  • Kristiina
    Taste is great but bit too sweet.
  • Rob
    Doesn’t mix at all well
  • Karen
    Love this use it to make Red Velvet protein waffles yum yum
  • Maxine Mckenzie
    First time I’ve tried this and will definitely be buying again, it’s lovely.
  • Gary M
    Great taste , use it in my porridge as well as having shakes , works equally well.
  • Laura Cruz
  • sharon
    great tasting
  • Customer
    Probably good stuff if you like the flavour but not what i was expecting
  • Richard Prince
    Best tasting shake I've ever had tbh. Wish they did it in protein isolate also but I don't know if the taste would be the same. Good stats anyway though!
  • Mandy
    I have tried all the flavours and this was by far the worst. Didn’t taste of birthday cake and was more like a very weak strawberry, I had to add flavadrops to make it drinkable. Most of the other flavours are brill, very disappointed with this one.
  • Jake Ferry
    Brilliant product with loads of free samples, brilliant company!
  • Avril
    This is awesome mixed with porridge oats
  • Karen
    Bit sweet for me but still drinkable
  • Holly
    Not the best flavour
  • Simon Lett
    I love phd's diet why range but this is so bad. It tastes nothing like the bars and even with milk is virtually undrinkable
  • lorraine tester
    Tasty, great texture, mixes well highly recommended
    Just a little bit to sweet but nice flavour
  • Dave Hughes
    Love the flavour. Great product and by far the best diet whey on the market.
  • Robert Gillespie
    Really nice flavour hope it sticks around
  • Nicole Turtle
    By far my favourite and I’ve tried lots of different flavours! Smells and tastes amazing!
  • Elaine Howitt
    Absolutely love this one for a sweet treat, fab on its own or blitzed up with ice & a few strawberries!
  • David Evans
    It’s ok, not a strong taste but my wife likes that because it’s not too sweet.
  • Claire
    Lovely tasting and thick
  • Eddy Robinson
    Love it.
  • natasha
    I love this flavour
