Pre-Workout Supplements
So, you have had a good meal with a wholesome meal, added carbohydrates to the body to replenish glycogen stores and provided some complete protein. Now you need to immediately provide the body with additional nutrients in the form of supplements to increase the effectiveness of the workout. Sports nutrition is quickly absorbed, therefore, it should be taken 15-30 minutes before training. The following is a list of some popular pre-workout supplements:

Whey protein is arguably the most important pre- and post-workout supplement. Provides you with protein and branched chain amino acids, which will be delivered to muscle cells as quickly as possible during training.
Creatine – increases muscle volume and energy, and also retains water in the muscles, which contributes to good hydration. It is a safe supplement.
BCAAs are undoubtedly essential amino acids in any bodybuilding diet. They promote muscle growth and recovery. However, the need for their use may be questionable. After all, protein powders (especially whey protein concentrate, not isolate) already have an excellent set of amino acids. Therefore, there will simply be no point in using BCAA, and it is worthwhile to better see the label on your whey protein in advance.
NO2 – nitric oxide, dilates the blood vessels so that more blood can be delivered to the muscles. This means that more nutrients can be delivered to the muscles.
Caffeine is an excellent stimulant that provides the body with energy and helps to concentrate. Caffeine works in the opposite direction of creatine (the former acts as a diuretic, the latter stores fluid), so you should choose one.
Leukic Hardcore – a complex of nutrients that maintains an optimal level of insulin in the blood and creates favorable conditions for maximum growth of muscle tissue.
Nano Vapor – a complex of special biologically active compounds, stimulates the anabolism of muscle cells and prevents the catabolic effect.
