Sure, okay. Also, I can take those questions. With regards to the centers we currently do have eight centers in various stages of development. Two are FDA approved, five centers are collecting plasma at present, by the end of 2022 we want to have 10 centers or more under our corporate umbrella, by 2024 we'd like to have all those 10 centers or more FDA approved, and really being in a place will be self-sufficient to bring in from a supply chain standpoint, the majority if not all of our raw materials, may be 600,000 liters of revenue or liters of plasma coming in from our plasma centers. Now, as you look at our inventories, ending the second quarter of 2021, we have $100 million in inventory, and half of that inventory. And this is a testament to show how much production, we've really been able to ramp up here in Boca, our working processes close to $50 million. And that's a testament to show how much the production has continued to increase here, we just got the 4400 approval process approved by the FDA just in April. So we think that that whip number is going to continue to grow, which is a good sign because as that whip number working process number moves through the manufacturing and filling phase of our seven to 12 month production lifecycle. A lot of that product is then going to go into the final phase, the finished good phase. So to answer your question, roughly, how much finished goods would we estimate to have on a quarterly basis if we're, since we've got it to $250 million Anthony in 2024, we say roughly a blended margin of about 50%. On a quarterly basis, you're looking at somewhere between $60 million and $70 million, a quarter at 50% gross margin, if they can somewhere around $30 million to $40 million. And it's at our cost of finished goods. So we're certainly well on our way, having a balance sheet of $100 million in inventory. At our cost thinking we've got about 50% gross margin on that number. We're certainly setting ourselves up for a very strong foundation that we've created to beat or achieve quarter-on-quarter, year-over-year revenue growth, again, which is a testament to these recently published financials for our second quarter.
