Methodology
How we rank every bag.
Independent and transparent. Every price is read from the retailer's own page and checked daily. Here's what goes into each score.
01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Real prices, checked daily
Prices come from the retailer's own listing, never an RRP, and we re-check them every day rather than leaving a feed to drift.
04
No sponsored placements
Rank order is cost per 25g of protein. Some outbound links earn commission; none of them buy a position in the table.
Questions, answered.
It depends on the specific product and timing. Myprotein runs near-constant sales which can make their headline prices look cheaper, but Bulk's standard pricing is often competitive without needing a discount code. The summary stats on this page show the current average across all products from both brands.
Both brands use similar manufacturing processes and ingredient sources. Independent lab tests generally show comparable protein content to what is stated on the label. The main differences are in flavour range (Myprotein has more options), customer service (Bulk is generally rated higher), and pricing strategy (Myprotein relies on discounts, Bulk on stable pricing).
