With bodybuilding most bodybuilders will agree that the only (legal) effective supplement for weightlifting is creatine, with vitamin D, fish oil, and multivitamins generally recognized as also useful for general health. But the most important “supplements” are anabolics which of course can’t be legally advertised. The problem is average Joe doesn’t know that, and bodybuilders need to make money (most make very little if any money from bodybuilding) so they do endorsements and marketing for health brands which are legal even if they may not be effective. Preworkout is a bit different because it actually is marginally useful for workouts, and I think most actual bodybuilders take some form of it. But it’s super cheap to produce so most of the expense is on marketing. You can make homemade PWO with stimulants and “pump supplements” for super cheap if you buy the raw compounds
