Training creates the signal recovery decides how much of it you keep. Miss the window and the session was mostly wasted. 7 things that decide whether your training turns into muscle, and where one sachet fits.

Training sets the demand. Protein is the supply, and neither one makes up for the other. OneFit gives you 25g of supply every day, so protein’s never the reason you fall short.
Muscle responds to hitting your numbers every day, not to one big effort a week. Most people don’t fall short because the target’s too high. They fall short because a rushed day turns into a skipped one, and skipped days add up fast. OneFit makes the daily number simple enough to hit anyway.
OneFit® is one 35g serve at 100 calories, taken once a day.
Training sets the demand, and some sessions go better than others. Protein is the side you fully control, every single day. 25g of hydrolysed collagen protein from OneFit, after you train, is the part you can always get right.
OneFit’s creatine isn’t a hormone, and it isn’t a stimulant, so you won’t feel it working. Your muscles store it and use it to refuel every rep. That’s the whole job, which is why the result is one more rep, not a feeling.
5g a day is creatine’s real, established dose, and it’s what OneFit gives you every serve. Most blends carry only a fraction of that, just enough to put the word on the label. Check the number per serve. That’s the only one that matters.
Not protein alone. Not creatine alone. OneFit is both, plus the electrolytes and micronutrients hard training burns through. One sachet. 100 calories. Once a day, after you train.
One 35g serve: 25g protein, 5g creatine, 1g L-Carnitine, 1g electrolytes and 16 vitamins and minerals, at 100 calories and 0g sugar.
Week 4 on OneFit, strength climbs and recovery keeps pace. Week 8, definition starts showing in the waist and face. Week 12, the difference is clear and energy stays steady. Individual results vary and depend on training, diet and consistency.
Week 4: strength climbs, recovery keeps pace. Week 8: waist and face lean out. Week 12: definition is clear, energy steady.

See all reviewsA training stimulus your body has to adapt to, repeated often enough, with enough protein and enough recovery for the adaptation to be paid for. Protein on its own does not build anything. It is the material the adaptation is built out of. That is why this page argues for the whole set rather than for one ingredient.
Most guidance for people training for lean mass lands somewhere around 1.6 to 2.2g per kilogram of bodyweight a day. The exact figure matters far less than hitting a sensible one consistently, which is where most people fall short, not on the number itself, but on the days a meal gets skipped. 25g in one serve is a floor you can put under those days.
No. Loading reaches saturation faster; taking 5g a day reaches the same place in about three to four weeks without the larger doses. Since OneFit is a daily serve, that is the route it takes. What matters is that you keep taking it. Saturation falls away when you stop.
Creatine monohydrate is among the most studied supplements there is, and 5g a day is the amount most of that research uses. It does draw water into muscle cells, which is part of how it works, so the scale can move early. That is intramuscular water, not fat. If you have a kidney condition or take prescription medication, speak to your doctor first, as you would with anything.
25g of hydrolysed collagen protein and 5g of creatine monohydrate per 35g serve: one sachet or one scoop, shaken into 300ml of water or a beverage of your choice. One serve daily.
After training, ideally. Exercise acutely increases metabolic responsiveness, so that’s the most useful window. On rest days take it at the same time each day, because creatine works by staying saturated, so the rest days count. Daily consistency matters more than perfect timing.
People who train at least a few times a week and want one daily serve covering protein, creatine, electrolytes, probiotics and micronutrients instead of managing four or more separate products. It isn’t a weight-loss product and it isn’t a replacement for meals.
It replaces the stack rather than adding to it. One sachet after training covers what most people were buying as four separate tubs. It does not change your programme, and it is not a substitute for one. The formula is built around lean mass and recovery, which is why 25g of protein sits beside 5g of creatine rather than either being sold on its own.
You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.
Per 35g serve: hydrolysed bovine collagen protein, micronised creatine monohydrate, L-carnitine tartrate, BCAA 2:1:1, glycine, magnesium citrate, potassium citrate, sodium chloride, turmeric extract, Lactobacillus paracasei, plus 13 vitamins and minerals, natural flavouring and sweetener.
Gluten: nil detected. Plant-based options use pea protein in place of collagen. Not intended for children, or for anyone pregnant or nursing, without medical advice.
Third-party lab tested every batch, with results published. Made in Australia to premium ingredient standards. The formula is versioned and revised as evidence develops. The current supply is v4.7.
Doses are set at amounts intended to be meaningful rather than label-filling: 25g protein, 5g creatine monohydrate, 1,000mg l-carnitine and 1g of elemental electrolytes per serve.
Take one serve daily, after training. Blend or shake one 35g sachet (or one scoop) into 300ml of water or a beverage of your choice. On rest days, take it at the same time each day.

Per 35g serve (1 sachet or 1 scoop), Chocolate Milkshake. 20 servings per package.
