I always use bulk for my protein powder needs. Their clear whey isolates are my particular favourite. Very good, very clear and come in a range of different flavours. Genuinely makes protein drinks easier, like drinking a cordial. They're low calories as well, 1.5 scoops is 30g protein and around 129kcals, so good for cutting and not losing those hard earned muscle gains. I have bought a range of other products from protein shakers to their food stuff such as the fibre complex (a sad reality of high protein, comes with the need for more fibre). Everytime I order, the delivery is fantastic. I'm kept up to speed with where it is and their couriers are always good, too. Only niggle is that you're supposed to get £10 off for orders over £50 and I often don't get it, even though my order didn't include products not included in that deal. However, I still find the price reasonable and really do enjoy them and the service bulk provides. Overall a very good company that I will continue to use.
