Performance: products for a wider training goal
Start by deciding whether the goal is alertness, a different training feel, or a specific ingredient with a narrow role.
The useful differences are usually whether the formula is about alertness, training feel, or a narrow ingredient with a specific role. A clear goal usually makes the category much easier to navigate.
A useful way to choose is to separate caffeine products, amino acids, carbohydrate support, and protein rather than treating all performance products as the same category. Sprint training, long sessions, and general gym work often call for different levels of simplicity.
This section works best when the goal is specific and the rest of the week is consistent enough to evaluate one change at a time. If you are still building regular meals, fluids, or sleep, those basics usually deserve priority.
