- For strong lungs and increased elasticity during exercise - Maximizes oxygen uptake for optimum performance Usage: For optimal preparation of the respiratory system before strenuous exercise, we recommend starting with Cavalor Bronchix Pulmo at least 16 (preferably 18) days in advance. If the risk is less high, 6 days is enough. To do so, administer 20 g (1/3 syringe) per day for at least 16 days (high risk) or 5 days (low risk). On the day before the increased workload and on the morning itself (or the previous evening if same day is not allowed) administer 30 g (1/2 syringe). This means 5-6 syringes will be required to prepare for a race, competition or high-intensity training and only 3 syringes if the risk is less. The daily maximum dose per horse is 60 g (1 syringe)
