While it is of course physically possible, you should not.
As of DMSI 3.1 it contains programming for changing your pheromone expression to what is ideal for achieving the program’s goals, causing your sexual attractiveness to be optimized for those who you are most attracted to sexually. Using additional artificial pheromones will unbalance that and lead to unpredictable results. In almost all cases, adding more will degrade the results that your subconscious mind achieves through this optimization process.
Therefore, do not use artificial pheromones while you are using DMSI 3.1 or later.
