Slow Release, Anti-Catabolic Formula

The combination of Micellar Casien and Calcium Caseinate makes Casein SR the perfect slow release formula to drip feed your body throughout the day or while you sleep. This timed release action makes it the perfect formulation for anyone who finds it hard to gain muscle weight (e.g. - hard gainers), or wants to take their training and nutrition to the next level and recover while they sleep.

Protein For Hard Gainers

Many trainers find it difficult to build muscle and gain weight no matter how hard they train or what they eat. Genetics and metabolism play a big role, but the good news is that a well planned diet can help overcome this dilemma! A diet rich in slow digesting and absorbing protein is one of the key factors in help "hard gainers" to pack on muscular weight. Protein sources like red meat are preferred protein foods as they are slower to digest and keep the body fueled for hours. The gold standard protein supplement for hard gainers should be based on casein - one of natures slowest digesting proteins. Casein is great for hard gainers because it reacts with stomach acids to take on a thick gel like consistency which is slow to digest and absorb. The result is that casein proteins provide muscle building amino acids to your body for up to 7 hours, giving your system a much longer stream of nutrients to use for recovery and growth. MAX'S Casein SR is the ideal protein for "hard gainers". Anyone who finds it difficult to add size and strength should simply add 2 serves a day to their diet.

Slow Release Night Protein

Casein proteins aren't just good for hard gainers. Every trainer can benefit from using a slow release protein while they sleep. That's because up to 60% of new muscle growth occurs while you sleep – if you give your body enough of the right nutrients. Don’t waste your hard hours in the gym with poor night time nutrition. MAX’S Casein SR is great protein to take before bed because it provides up to 7 hours of continuous protein release to keep you recovering and growing all night while you sleep. It combines ultra-slow releasing Micellar Casein with slow releasing Calcium Caseinate and medium releasing Whey Protein Concentrate so you will wake up recovered and ready to tackle each new day and each grueling workout.

MAX'S Casein SR Contains:

  • Milk Protein Concentrate - is produced by ultrafitration of whole milk. It is high in casein protein fractions including Micellar Casein and Calcium Caseinate.
    • Micellar Casein - is an ultra-slow digesting and anti-catabolic protein that inhibits muscle breakdown after hard training. Clinical trials show Micellar Casein can sustain elevated blood amino acid levels for up to 7 hours.
    • Calcium Caseinate - is a slow digesting protein that is ideal for trainers with a faster metabolism. During digestion, bioactive peptides are released to enhance anabolic growth and improve your metabolism.
  • Whey Protein Concentrate -  is a medium digesting and releasing protein, faster acting than Caseins. It provided the initial boost of amino acids for the initial few hours of sleep. WPC is also a rich source in immune boosting protein fractions to help keep you healthy during intense training phases.

Tried it

It’s not like the other night drink but if you have it not long after dinner the 30 minutes before bed have anabolic night it’s ok 👍🏼

Great order

It’s a good service

Nice protein

I like this protein as it serves me more as a weight gainer than a slow release

Great Taste!

Not too thick and overwhelming like other powders and dissolves well. Taste is on point. Great product


I typically do not prefer vanilla but it taste great and mixes well.

MAX'S Casein SR Ingredients

Milk Protein Concentrate (Micellar Casein, Calcium Caseinate), Whey Protein Concentrate


Does Casein SR contain any stimulants that could keep me awake?

No, Casein SR is stimulant free. In fact the formula is designed to promote peaceful sleep.

Can I add other supplements to Casein SR like BCAA’s?

Yes, adding supplements that don’t contain any stimulants will contribute to your recovery even further.

Will training late in the day or in the evening affect my sleep?

Everyone’s metabolism is different, but generally weight training will speed up your metabolism for several hours after the completion of your workout. If you find it hard to sleep peacefully after training late in the day you may need to change your training time to a little earlier. Casein SR will definitely help calm down your metabolism however you may need to adopt some other techniques to bring your metabolism down to normal. These include hot and cold showers, a hot bath, massage or yoga.
