###Human: I was advised to take Nano Leo to improve my sexual desire. Will it help? ###Assistant: Hi. Your testosterone levels are in normal range, but still, they are at low normal levels. You are a hypertensive too and also taking antidepressants. Both these, along with age are contributing to reduced libido in your case. First of all, there is no need to feel ashamed to talk about sex. You can speak to the psychiatrist and consult him properly. If there is no improvement on taking Nano Leo (Elemental zinc with Tribulus Terrestris), then you can think of taking PDE5 inhibitors (Phosphodiesterase) like Sildenafil or Tadalafil. Both are good drugs, and they are safe to use. Tadalafil has a long duration of action, and it will provide a good erection.
