It is under active study, but there is no diagnostic test and no treatment proven in randomized trials . The FLCCC/IMA I-Recover protocol is a layered, off-label regimen (time-restricted eating, ivermectin, nattokinase, low-dose naltrexone, supplements) built from proposed mechanisms, clinical observation and patient anecdotes. Evidence-based first steps: see a clinician to exclude treatable causes (myocarditis, thyroid disease, anemia, POTS, sleep disorders), pace your activity, and consider joining a research study. The Independent Medical Alliance (IMA), previously known as the FLCCC, offers a detailed plan called the I-RECOVER protocol. It's a detailed guide for addressing post-...

Dr. McCullough explained (1) that the spike protein is an engineered, synthetic molecule roughly 1,200 amino acids long and resistant to degradation by the body’s normal proteases. He described how the protein was modified in laboratory settings (notably at the Wuhan Institute of Virology) to tightly bind to the ACE2 receptor, which is found throughout the body—in the lungs, heart, endothelium, kidneys, and brain. Because this receptor regulates angiotensin metabolism, older individuals with fewer ACE2 sites catabolize the spike less efficiently, leading to worse outcomes. Whether introduced by infection or by genetic‑code‑based vaccines, McCullough asserted, the persistent spike damages tissues directly and through chronic inflammation, micro‑clotting, and autoimmune cross‑reactivity.
