Maxs WPI HL Review

Maxs WPI-HL Whey Protein Isolate

Max’s WPI HL Review

In March 2014, the hugely popular Max’s protein range was completely revamped as part of their ‘Back in Black’ campaign. All your favourite products – whether a weight gainer, lean protein, WPI or whey blend has been reformulated and repackaged. No longer do Max’s proteins come in the black plastic tubs they’ve been known for using for many years – they’re now all in boxes similar to the Supershred and Superwhey products. Not only has the packaging undergone extensive redesign, but most of the products have too – and we think they’re going to be more popular than ever.

Max’s WPI-HL is the new version of the Bioengineered WPI, which was a hugely popular protein supplement for many years for anyone looking to boost their lean muscle gains. The new Max’s WPI High Leucine boasts a greater leucine content than the previous version – meaning greater anabolic signalling and even better muscle growth and recovery. It still has a whopping over 90% protein, which was one of the biggest selling points of the original blend, as well as ultra-low carbs and fat.

Max’s WPI-HL Key Ingredients

  • Whey Protein Isolate – The main ingredient in Max’s WPI-HL is a high-leucine whey protein isolate. This is one of the purest protein sources you can find, and is already normally very high in leucine – that key amino acid that stimulates muscle growth through mTOR signalling. Whey isolate is the ideal protein for anyone looking to make lean gains, and is best used first thing in the morning or around workouts.
  • Pepform Leucine Peptides – Pepform is a brand of leucine peptide that is becoming more popular particularly in BCAA supplements and protein powders. By using leucine peptides rather than standard l-leucine, there is an even greater (and faster) insulin response and muscle growth signal leading to (you guessed it) quicker and more effective muscle gains.

Max’s WPI-HL Flavours & Sizes

Max’s WPI-HL comes in a 1kg and 2.2kg box, which gives you 33 and 73 serves, respectively. The current flavours on offer are Chocolate and Vanilla.

Max’s WPI-HL Dosage

Each scoop of WPI High Leucine is 30g, which gives you (an almost unmatched) 27.1g of protein. This is fantastic, and means that there is very little else in the mix other than high quality whey protein isolate. With the high leucine content and the Pepform added to the blend, you’re getting a huge anabolic signal with each serve, so you don’t actually need to take that much. Start with 1-2 scoops per day and assess your results.

Why we like Max’s WPI-HL

  • Ultra-pure blend
  • Boosted with leucine peptides
  • Over 90% protein


Max’s new WPI-HL has given an upgrade to an already excellent whey isolate supplement, and is clearly one of the best whey protein isolates anywhere in the world. With over 90% protein, boosted with a higher leucine content, and with an ultra-low fat and carb ratio, the new Max’s High Leucine WPI is the perfect tool to boost your muscle growth.
