It is difficult to answer exactly how long it takes to take Luo Teng Fu Ke Bi Ri Pill, because the effect of taking the medicine will vary depending on the patient’s condition and constitution. The main reason for this is that it is a good idea to take a look at the actual product. Some patients with mild symptoms of sexual dysfunction may have some effect after taking Rohypnol Pill for two weeks, while some patients may take the medicine for a month or even three months to have effect, so the specific effect time is not fixed and needs to be combined with the patient’s personal situation. The patient should also pay attention to avoid spicy, cold, greasy food during the medication, and patients with sexual dysfunction should also pay attention to a balanced diet, more protein and other nutrients, and do more exercise.
