Ideally, you want to have all aspects of your body and brain in optimum performance mode before a competition and then continuing throughout it. Since Aimcise supplements are not drugs, that means the supplements need some time to work and allow your body to start achieving improved performance.All Aimcise products have a recommended serving size per day (all bottles typically contain 30 days worth of servings). Please follow the instructions on the label. Depending on what kind of shooter you are and how often you have competitions, leagues, or just fun shoots, here is what we recommend:Tournament shooters & Year-Round competitors: For those of you that don’t have significant breaks between shoots and essentially shoot year-round, Aimcise suggests taking your Aimcise supplements every day throughout the year, without any breaks. If you are looking to keep your performance at its highest level, you can’t stop taking the supplements and expect the same results year-round. This is similar to working out – you don’t expect to be able to work out with the same strength and endurance if you take a couple of months off, versus continuing to workout without any breaks. Daily supplementation ensures you have given your body everything it needs to perform year-round.Occasional shooters & seasonal competitors: For those that don’t compete all the time, or go significant amounts of time between competitions and shooting we suggest you should start your Aimcise Professional Shooting System plan at least 30 days before a big tournament, shoot, or league event, and continue to utilize the products throughout the competition to maintain the peak condition you have achieved. Trying to utilize Aimcise products less than 30 days before an event generally will not allow your body and brain enough time to rely on the benefits of the ingredients to achieve maximum performance.
