Product Info

NPL Casein Slow Release is a night time protein shake for optimal recovery and muscle gains.

Protein For Muscle

To get muscle growth athletes and lifters regularly consume protein throughout the day.

Each meal has some meat and they may supplement with a protein shake or two.

A serving of this shake is a quick and convenient way of getting 21 grams of quality protein which is similar to a chicken fillet.

Feed While You Sleep

You grow while you are sleeping and not training.

It is very important that you give your body enough nutrition during your recovery periods to maximise gains.

Micellar casein has been used in this shake which is slow digesting, supplying muscle building amino acids for up to 7 hours while you sleep.

Digestive Enzymes

Digezyme® enzymes are included to enhance digestion of protein and absorbability of the other nutrients in this product.

Perfect Desert Replacement

To make a sugar free desert simply add 2 level scoops of powder to a bowl, slowly add water or milk and refrigerate for 5 minutes.

Fills The Nutrition Gap

NPL Casein Slow Release is a complete night time recovery protein shake to give your body the nutrition it needs the most to recover quicker and grow faster.

Epic protein
Review by Guest (19 July 2022)

Nice protein
Review by Guest (18 July 2022)
Very filling and great quality
Excellent product
Review by PD (21 March 2021)
This is by far my favourite from all the different caseins that I’ve tried. The texture is drinkable as it is not extremely thick like other caseins and it also has a relatively nice but sweet taste (I had the chocolate flavour). Recovery is very fast with this product. Well worth the price.
Way too sweet
Review by Flo (10 May 2020)
Impossible for me to drink, it’s so sweet that I can’t even explain it. No idea how anyone can drink this
Filling and Tasty
