Shipping & delivery


  • 25g of protein per serve
  • 1.7g of carbs per serve
  • Highly bioavailable, rapidly-absorbed whey protein isolate in every serve
  • Packed with amino acids needed to optimise rapid protein synthesis
  • Moves your body from catabolic to an anabolic state
  • Helps control cravings and curb your appetite
  • Increases your your body's natural antioxidant defences

Right after killing it in the gym, there is a window of opportunity to flood your body with the amino acids to optimise rapid muscle protein synthesis. This moves your body from a catabolic state, where muscle is breaking down, to anabolic state, where your body is building bigger, stronger, more developed muscle than before.

ONEST'S Whey Protein Isolate provides 22.8 grams of highly bioavailable, rapidly-absorbed whey protein isolate in every serving, so you spare no time giving your body exactly what it needs to maximise your gains. Did you know engaging in strength training almost double your protein needs?

Fortunately, it’s never been easier to meet your higher protein needs. Plus, since ONEST's whey protein isolate is 90% protein, you don’t have to worry about upping your carbohydrate or fat intake just to get enough protein. That sets you on the fast-track towards awesome muscle hypertrophy and ideal body composition.

Compared to other brands on the market, ONEST Whey Protein uses only 100% pure whey protein isolate. And that’s a big deal when it comes to all things concerning your appetite and hunger levels.

When about 30% of your diet is made up of protein, you have a leg up towards achieving your ideal body weight. But when you consume whey protein isolate, you get a ton more benefits that help with healthy weight management, like diminished hunger and steady blood sugar levels.

ONEST's WPI can actually help suppress the hormones that make you feel hungry, like ghrelin, and stimulate the hormones that help you reduce body weight, like GLP-1. Just another reason why ONEST's Whey Protein Isolate is vital to helping you achieve your body goals.

Exercise actually generates tons of free radicals that wreak havoc on your body, damaging your tissues and cells. Pretty surprising that exercise would have such a dark side to it, isn’t it? Fortunately, there is some good news… Studies show that when the consumption of whey protein isolate is combined with resistance exercise, you massively increase your body’s natural production of antioxidants; exactly what you need to fight those nasty free radicals.

Wondering what free radicals mean for you in real life? Free radical production from exercise may actually be damaging your muscles.

Stimulating your body to cope with this insult not only helps you to maintain healthy muscle tissue, but it may also help combat the loss in muscle force that is characteristic of exercise-induced muscle damage. With Onest Whey Protein Isolate you can rest (and recover) easy knowing you are providing your body with exactly what it needs to protect itself from the harmful effects of pushing yourself to the limits.
