Been using this as my regular Casein for five years

Review by Clint on Oct 29, 2023

So I'm an old, broke down man. Early forties, never had a taste of the HRT, but I still OHP for reps in the low 2's, bench for reps in the low 3's, squat for reps in the low 4's and deadlift for reps in the low 5's. I've been using ON Casein for half a decade now as my pre-bedtime protein dose (it's fine for a shake, but I make a pudding). Now give me my 5% discount.

Great for cooking

If you want the best protein pancakes you need to use ON Casein. Generally cooking and baking works best with casein with a few exceptions. Will always buy Optimum Nutrition as it is the market leader and offers the highest quality. It is the difference between buying best product or the supermarket own brand.

Best flavour so far

Love the chocolate flavour that almost has like a hint of coffee/caramel taste. I take whey in the am and casein in the pm before bed for slow overnight recovery. Love it and will stick to it.

Great product, love the flavor. Perfect protein drink after an early evening workout just before going to bed. Feeds the muscles while sleeping and aids in quicker recovery time. I will be ordering this product again soon.

Best protein product I’ve used. Mixes really well in porridge and if you add around 150ml of water it makes a protein pudding. Should be advertised more.

I use the Chocolate Supreme and Creamy Vanilla in drinks and in my home made protein muffins. It taste great and mixes well in the drinks and the muffin mix. It's a great product!
