The goal of this prospective, observational study is to compare the quality and quantity of the cellular content of platelet-rich plasma harvested after administering one of two cell-stimulating proteins, filgrastim and pegfilgrastim. The main question it aims to answer is: • Will participants have a similar cellular content when comparing a 4-day filgrastim treatment to a one-day pegfilgrastim treatment? Participants will have the following intervention administered: * 130mL of blood will be drawn on the first visit after consent and in followup visits after administering treatment (4 days for filgrastim, 7 days for pegfilgrastim) * Half of all participants will receive filgrastim first, followed by pegfilgrastim 8 weeks after filgrastim treatment concludes. The other half will receive the treatments in reverse order Researchers will compare the quality and quantity of cell content after each treatment administration as well as comparing differences in data dependent on which order treatment was given.
