This comparison covers two exact packs of plain, unflavoured creatine monohydrate powder: Optimum Nutrition (ON) 317g and Bulk 1kg. Compare the total delivered price against the powder weight. Gummies, capsules and flavoured blends need a different comparison; micronised describes processing and does not establish better results.
A useful starting point
ON is the smaller purchase at 317g; Bulk supplies 1,000g. Neither is always cheaper per 100g. Divide each delivered price by its pack weight in grams and multiply by 100; the lower result buys the same powder weight for less. For example only, ON at £20 costs £6.31 per 100g and Bulk at £25 costs £2.50 per 100g. These are illustrative prices, not current offers or a quality ranking.

What matters before you buy
A few checks that make the choice more useful.
Use the checkout total including delivery and any discount you can actually use. Compare the two unit prices before deciding whether the larger pack suits your budget.
Keep the selected variant unflavoured and confirm 317g for ON or 1kg for Bulk. A different size or flavoured formula needs a fresh calculation.
Keep powder weight separate from the label’s creatine amount: Bulk lists 5g creatine monohydrate, of which 4.4g is creatine. This comparison uses pack weight, not active-creatine content or cost per dose.
This buying guide does not prescribe a dose or assess individual suitability. A lower price per 100g does not establish better quality or health results.
