Sure. So thanks, Anthony. As far as your first question prescribing habits of our writers, obviously it's mixed. We have some big writers that have adopted XYOSTED and it's probably their first-line therapy for most patients. What we see is that, obviously, they're offering it to new patients, and we're seeing a really nice number of patients that are new to therapy. About 50% of our scripts are patients who've never been on another testosterone therapy. So that shows that the doctors viewed as a strong first-line therapy, as well as when the patients given the option between gels, IM injections, or XYOSTED, they are picking XYOSTED. So we're seeing a good mix of patients. And then other doctors are switching their IM patients. Again what we found is that most doctors will say, hey, if the patient doesn't complain, we're not going to offer it. But if they're complaining, they offer XYOSTED, and if they switch, they tend to be happy. But a lot of it has also do with coverage. We're really now at a nice percentage of lives covered for XYOSTED, but it took through October to get there. And with any product launch, it takes anywhere from six months to a year to get relatively good coverage, if you get it at all. And we got 70% of all lives covered. So I think we'll start to see the patient demographics really changing based on their coverage. If they weren't covered, it was an expensive proposition to change from a generic IM or generic gel to XYOSTED. So we're seeing all kinds of doctors, we call them internally like dabblers, adopters and something else, I can't recall exactly what it is, but it's – I think it's normal. In that, you have doctors who are aggressive in looking at new therapies and adopt them and it becomes a big part of their practice, and then others who take time, and they want to hear from other doctors, they want to hear from patients and so forth. So I can't say that we have one particular doctor – type of doctor that writes heavily and ones that don't. I think we're seeing a really nice mix of doctors like I said in my prepared script, 3,500 physicians have written XYOSTED, we call on about 12,000, and probably 10,000 on a regular basis. And so that's a pretty good mix in a very early – in a very short period of time to get that number of doctors writing, and then also the number of patients that are using XYOSTED. I think what's important is, as we continue to get new patients, the persistence has been really strong and so the refills become more and more important. And we're – and again, I think we're seeing better persistence than what you typically see in testosterone products. And if that trend continues, we think we'll continue to see a really nice growth with the product. Your second question...
