Treinando is a database for training decisions, built around comparison instead of marketing. It organises supplements, equipment, exercises and training data in one place, so the question you are asking is answered by two rows next to each other rather than by a headline. Four paths organise the content: what to observe in a supplement, with composition, dose and format; what an ingredient does, with usage, timing and limits; how two options compare, with metrics side by side; and how to organise a movement, with execution and the muscles involved. The ingredient library covers beta-alanine, caffeine and micellar casein. A whey protein concentrate is listed with 24 g of protein per serving in a 900 g tub, and the zero-lactose variant with 22 g per 30 g serving, and where a product comes from an affiliate offer the site asks you to confirm the variant, the price and the availability before buying. The exercise library covers rope cable crunch, wheel crunch and dumbbell lunges. Everything is searchable, in Portuguese.
