Calculate it yourself
Delivered pack price ÷ pack mass in grams × 100 = price per 100g of creatine monohydrate powder. For example, £20 ÷ 317 × 100 = £6.31 per 100g, while £25 ÷ 1000 × 100 = £2.50 per 100g. These are example prices, not current offers.
Round each unit price to two decimal places, then subtract the lower displayed price from the higher one. In the example, Bulk is £3.81 less per 100g. Equal displayed prices are a tie at penny precision, even if their unrounded values differ slightly. Very small unit prices can round to £0.00.
You can use this method without JavaScript. A lower unit price does not establish better quality or suitability, and the larger pack can still cost more upfront. For ingredient and label context, read our plain creatine monohydrate buying guide.
