Pump supplements from the category of nitric oxides cause blood vessels to open, and blood to be pumped to the vessels, and as a result, they bring quick and short-term hypertrophy and are good for muscle energy. Therefore, I recommend not using standard resistance training programs in the early months. Also, this supplement will not be used until we are sure of the athlete's cardiovascular health. Foods like watermelon juice also act as pump supplements. Pay attention to avoiding using pump supplements along with katsu exercises (BFR Training). Some of the best supplements in the field of pumps:
