Aside from the real economic problems, many people have inexplicable or even ridiculous resistance to supplements. Even I can't tell you. I can only say that people who can practice and are willing to practice will definitely eat powder cheaper than meat. It is basically a joke to supplement it by drinking milk (in the 1990s, it was nonsense to say that a glass of milk every day was to strengthen a nation, but nothing could be practiced with this mentality). You need to weigh at least 65,440.70 kilograms of protein a day, and the figure here exceeds × 1.5 grams.
