Product Description

Product Description


Supports rapid muscle growth, definition, strength and recovery.

Powerful support nutrients: Beta-Ecdysterone, Methoxyflavone and Chromium Picolinate.

Fast-Acting Whey Protein.

High Protein for lean muscle growth.
Creatine for strength & power.
Glutamine for muscle repair and recovery.
Rich in BCAAs for muscle maintenance.

PROMAX EXTREME is an advanced whey protein shake ideal for supporting your lean muscle, definition, strength and recovery goals. Loaded with a powerful array of 7 muscle building and performance nutrients including Biomax whey protein, Maxpure creatine monohydrate, glutamine, beta-ecdysterone, methoxyflavone and chromium picolinate. Promax Extreme is one of the most advanced protein products available.


Packed with 25g of protein per serving to support lean muscle growth and recovery.

Includes the highest quality Maxpure® creatine monohydrate for increased strength and power.

To aid muscle repair and recovery, Promax Extreme is rich in glutamine. Glutamine is considered by many nutrition experts to be essential for anyone exercising regularly. Glutamine reduces the risk of overtraining as well as supporting your natural immune defenses, one of the most important amino acids in muscle tissue.

Rich in Branch Chain Amino Acids (BCAAs) which are used for energy during exercise and play a key role in supporting muscle growth and repair.

Because it's digested so quickly, Promax Extreme is perfect for use before and after exercise. Studies show that protein taken at these times stimulates muscle growth more quickly than at any other time†.

To further support your physique and supporting goals. Promax Extreme is loaded with a potent collection of popular ingredients currently available including beta-ecdysterone (Suma extract), methoxyflavone and chromium picolinate.

Our easy digesting formula is virtually lactose free and therefore suitable for people with lactose intolerance when mixed with water.

Promax Extreme contains Biomax - an exclusive blend of whey protein isolate, hydrolysed whey and whey peptides. With a high Biological Value and rich in both Essential and Branch Chain Amino Acids (BCAAs), Biomax provides a rapid delivery of amino acids after every workout to help repair and rebuild lean muscle tissue.

Biological value relates to how much of the protein consumed is actually absorbed, retained and used by your body. It's a more accurate and up-to-date method of measuring protein quality than PER, NPU or Chemical Score.
Whey (as found in Biomax) 104 +.
Whole egg 100.
Egg white 88.
Fish 83.
Beef 80.
Chicken 79.
Casein (including micellar) 77.
Soya protein 74.

Promax Extreme contains a unique blend of whey proteins (Biomax), considered by experts to have a higher Biological Value than any other protein source, including casein, egg, chicken or fish. NOTE: BV is not a % but a value that takes egg as a constant at 100. Wheys unique amino acid ratio exceeds that of egg.

1.0 out of 5 stars NOT the same product as advertised 2 Nov 2011
Flavour Name:Chocolate|Size Name:908g
I have to mark/edit this down to 1 star from my previous 5 stars. I get my monthly hit of Promax extreme from Amazon subscription and my latest batch I received tasted different and a little sour. I also noticed that it did not mix as well in Milk as it all clumped up at the bottom of the shaker (mixes well in water but require more shaking effort). Now, I knew from past experience, this is not the great Maximuscle Promax Extreme that I have been taking, so I contacted Maximuscle to ask if it was safe to drink as I may have a bad batch. While I was waiting for them to reply, I did a little bit of investigation to the tub and realised the nutrition value is different. My immediate thought was that Amazon has sent me a fake tub. I then went on to the Maximuscle website and confirmed that they have changed the product by downgrading (IMO) it's quality.

Instead of the previous 85g of protein per 100g, You now get only 65g per 100g. A massive drop in protein levels.

Glutamine has decreased from 5.5 to 3.7g per 100g. Creatine looks to be at the same level.


I then received an email back from Maximuscle (looks like part of GSK), that I should not be mixing with milk and should only be used with water. I swear they have always stated to use milk to take advantage of the casein during bed time? I have lost all confidence with the brand. I am now changing product to Optimum Nutrition and staying well clear from Maximuscle.

I did reply asking a reason for the sudden change of quality, no reply and that was over 7 days ago.

This is for the Chocolate flavour, so who knows about the other flavours. Amazon - please update the product description please, In fact create a new product page as all the previous reviews are not accurate anymore.

5.0 out of 5 stars An excellent supplement to help you bulk up 13 Jun 2011
Flavour Name:Chocolate|Size Name:908g
The combination of high quality protein, creatine and glutamine makes this product perfect for building muscle mass when weight training intensively 3-4 times per week. The creatine helps improve strength and power and the glutamine helps aid muscle repair which is very important after training sessions.

I would recommend taking one scoop before training and one scoop after training. The powder mixes well with water or milk and the majority of the flavours are very tasty. Having tried all of the flavours, I would recommend Strawberry, Cookies & Cream or Chocolate.

After having taken Promax Extreme for approximately 3 months I have noticed an increase in my strength and my physical size after regularly playing rugby and participating in weight training.

Overall, a great supplement for anyone looking to increase their muscle size and strength.

2.0 out of 5 stars Some Warnings 20 Feb 2012
By Athlete
Flavour Name:Banana|Size Name:908g
As the other reviwer mentioned, this product does indeed give you some digestion problems. It is a very effective product if you take it regularly, twice a day even on days you don't train, you will notice very good results within 1.5 - 2 weeks. However, as mentioned by the product itself, that result is usually the build up of water in your muscles which you then use to lift heavier weights/train harder then shed the water to leave the newly built muscle. However the gain in water was a huge problem when playing sports like football and rugby. You will suffer from a significant slow down in carrying additional weight which is not muscle. I would recommend Promax instead if you are an athlete. If you desperately want to look muscular and show off then this could work for you.

By TAB91
Flavour Name:Chocolate|Size Name:908g
Excellent product but slightly hard to distinguish a difference between promax extreme and ordinary promax. However, after a while of taking this product there is probably a more rapid change noticable. But great-tasting and easy to drink

5.0 out of 5 stars Amazon price hikes 18 Dec 2009
Flavour Name:Strawberry|Size Name:908g
The product is as good as it has always been but I have stopped buying it from Amazon as the price just kept going up and up - I can now buy it a couple of pounds cheaper on the high street and I din't have the bother of waiting at home for the delivery man.
