Is BSN a good brand?
BSN is a flavour-led brand, and Syntha-6 is the reason most people buy it: a multi-source blend that has kept a following on taste rather than on protein percentage. Syntha-6 Edge is the leaner version of the same idea. The True Mass line covers gainers for anyone eating for weight. Be clear about which you want, because a blend built for taste and a gainer built for calories will both look dear per 25g of protein next to a plain isolate. WheyWise tracks 3 BSN products across 3 types, from £1.69 per 25g of protein on Syntha-6 Edge Protein Powder 1.82kg up to £2.83, across 1 UK retailers.

Frequently Asked Questions
How much does BSN protein cost in the UK?
BSN currently ranges from £1.69 to £2.83 per 25g of protein across the UK retailers we track. The cheapest right now is Syntha-6 Edge Protein Powder 1.82kg.
What is the difference between Syntha-6 and Syntha-6 Edge?
Syntha-6 is the original multi-source blend, carrying more fat and carbohydrate per serving. Syntha-6 Edge is the leaner version, with more of each scoop given over to protein. If you are tracking calories, Edge is the one to compare; if you are buying on taste, the original is the one people come back for.
Is BSN True Mass a protein powder?
No, True Mass and True Mass 1200 are weight gainers. Most of each serving is carbohydrate, so they add calories rather than protein alone and will always look expensive on a cost-per-25g-of-protein basis. Compare the Syntha-6 products if protein is what you are buying.

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
Rankings can't be bought
Rank order is cost per 25g of protein. Some outbound links earn commission, and some Amazon links marked Ad pay per click; none of them buy a position in the table.
