Mrs Sara Woods

This is very nice products

Mohammed shoeb Khan


This taste so nice is a great price and last ages. Great product



Fast delivery, great taste. Definitely will buy again



Tastes good, usually. Go for strawberry but tried the banana as it was on offer and also tastes good. Price and quality always good on PHD website so don’t bother shopping around anymore, just go straight to their site. If you’re not to fixed on the flavour you can usually pick up a good bargain with the deals on the website, no mucking about with promo codes to get a good deal.

Mr G


This is one of my favourite flavours

A Fab tasting Protein



Tastes great. I have been using this as a post workout protein boost and occasionally add berries, half a banana and ice for a thicker smoothie like shake.

Natalie Scully


Really yummy and filling. I drink it around 1PM, usually by the time i start to feel hungry. I wont feel my hunger till about 2:30PM. Usually by 1:30 i am starving i could eat a cow

동일중량에 프로틴이 이만큼 많이 들어가는 회사는 phd밖에 없어요. 다른 회사꺼 먹어보려고 해도 단백질 함유량보고 다시 phd꺼를 시켜먹습니다. 한국인들 2주정도의 텀을 두시고 phd꺼 시키세요! 이번해외배송은 일주일 걸렸습니다. 바닐라 딸기 쏠티드 카라멜 벨지언초코가 제일 맛있네요. 다음엔 민초와 화이트초코라즈베리도 먹어보겠습니다.!!!기대되요!!

Great price great service 👍

christopher hatherly


Love this protein powder

Helen Murray


Got this for my husband, don’t think he has enough protein , he really likes it



Good products but way too much sweeteners or sugar, (whichever of these they use). They are unbelievably sweet if taken as directed. Have to water them down much more than prescribed to make them drinkable. But the product is good other than that and the website was easy to use when buying.
