Startup cost: $0 - $50

Plasma donation itself does not require any upfront investment as donors are typically compensated for their time and plasma. However, for those who want to optimize their experience, potential costs could include transportation to and from the donation center, nutritional supplements to maintain health, or a fitness membership to ensure physical eligibility. These are optional and not necessary to start. Most people find this to be a low-cost side hustle, but costs can increase if one chooses to invest in health and wellness to improve donation outcomes.
