Trained by JP
Every Trained by JP protein product tracked, ranked by cost per 25g protein. UK pricing across stocking retailers, each price shown with its check date.
Trained by JP is worth a look if you want a range that covers most protein formats without leaving one brand. The line splits into a Performance tier (Performance Protein and Performance Isolate), a leaner Iso Pro and Clear Iso, and a vegan option, so you can move between a blend, an isolate and a clear juice-style shake without changing brand. WheyWise tracks 9 Trained by JP products across 4 types. The cheapest works out to £0.64 per 25g of protein on TBJP Vegan Protein 2kg, with the range running to £1.64 across 4 UK retailers. It is sold almost entirely through third-party supplement retailers rather than direct, so the spread between shops is where the saving is.
UK prices on every Trained by JP product we track, ranked by cost per 25g of protein. Every price is shown with the date it was checked.
Trained by JP currently ranges from £0.64 to £1.64 per 25g of protein across the UK retailers we track. The cheapest right now is TBJP Vegan Protein 2kg.
Performance Protein is a blend, so it carries more of the carbohydrate and fat that come with whey concentrate and generally costs less per gram of protein. Iso Pro is an isolate, filtered further so more of each scoop is protein. Compare them on cost per 25g in the table above rather than on headline tub price, because the isolate delivers more protein per scoop.
We see it at several independent supplement retailers rather than at the brand's own checkout, so prices move around more than for direct-sale brands. The table above shows every UK retailer we track with the date each price was checked.
