Multiple international and Chinese whey protein brands, including Myprotein,
Optimum Nutrition (ON) and MuscleTech, have increased prices since January, with
several domestic brands reporting similar moves. Some 5-lb (≈2.27kg) SKUs are
about 100 yuan above early‑year or prior purchase levels. Overall, mainstream
whey protein prices have risen roughly 20% year‑to‑date.
