Ten athletes made headlines in just three weeks. Blood clots. Cardiac emergencies. Cancer. Sudden deaths. A heart transplant. Different athletes, different circumstances, and some questions that remain unanswered.

Unbelievable ... 😡😡😡 The CDC tracked 10M Americans after each COVID shot. 7.7% reported needing medical care. 81% of US adults took at least 1 shot. Millions of Americans deserve answers: Where's the follow-up? Where’s the transparency? Who's being held accountable? From @P_McCulloughMD:

COVID Causes Blood Clots. That Isn’t Controversial — Except, Apparently, at the Bedside. Thrombosis after SARS-CoV-2 infection has been in the peer-reviewed literature SINCE 2020. Textbook, not fringe. And patients who had COVID and then threw major clots report being told by major institutions the infection had NOTHING TO DO WITH IT. Not “uncertain.” Not “possibly.” Flatly ruled out, with nothing offered instead. That’s not caution. That’s declining to think. @stinchfield1776 #MedicalFreedom

“NATURAL CAUSES” — OR ARE WE MISSING SOMETHING? Why are healthy young people and professional athletes experiencing blood clots and premature deaths? “So if someone takes the vaccine and they're producing tons of spike protein, but the antibodies are perfectly neutralizing it, they're gonna be fine. They can have a very high antibody tighter, but they'll be fine. But if the antibodies begin to switch to less neutralizing antibodies, I think this happened in Jalen Hertz, then the spike protein can roam free, cause blood clause, heart damage, stroke, and all kinds of problems.” Dr. Peter McCullough joins Grant Stinchfield to discuss: • Jalen Hurts, Deion Sanders, Damar Hamlin & more • COVID vaccines, spike protein & blood clots • mRNA cancer vaccines • Peptides, testosterone & healthy aging WATCH the full interview with @P_McCulloughMD and @stinchfield1776:

Year-to-date as of September 25, 2026, there have been 231 American COVID-19 vaccine deaths reported to the CDC. They have told us nothing. How many boosters? When was the last shot? Cardiac arrest, blood clots, cancer? Any other product would be off the market with these 2026 numbers alone. How can the current administration seeking to maintain power in the midterms stand behind this? @POTUS @SecKennedy @MAHA_Action @MaryBowdenMD @ShannonJoyRadio

Mass death reported to the CDC did not need sophisticated algorithms. Prompt action was required to shut down the program early in 2021. Every VAERS reports has patient contact information--CDC has 12,000 employees all able to call and get more information. @OpenVAERS

The Problem May Be the Processing, Not the Food Phthalates — plasticizers with DOCUMENTED ENDOCRINE ACTIVITY — leach into food from processing equipment, tubing, gloves and packaging. Measured exposure in people tracks with HOW PROCESSED THEIR DIET IS. That’s a separate question from the ingredient list. And ultra-processed food drives the obesity that suppresses testosterone directly. Two mechanisms, same supply chain. @jsolomonReports @AmandaHead @RealAmVoice #MedicalFreedom

Dr Ralph Baric and the Wuhan Institute of Virology published a fully functional SARS-CoV-2 prototype capable of invading humanized respiratory tracts of animals. So it was able to dock with ACE-2 and had the furin cleavage site in the code--never revealed in the Menachery papers. All the subsequent events flow from this primordial strain and work that started circa 2012 by Baric, NIAID, DARPA, and WIV. @Baric_Lab @NIH @DARPA @johnsearsleake

What does a law passed 40 years ago have to do with vaccine safety today? Dr. Mary Talley Bowden explains the connection in three minutes. Watch the full video.

Olivia Munn had a normal mammogram. She had also tested negative for BRCA and other cancer-related gene mutations. But her doctor went one step further and calculated her lifetime breast cancer risk. Her score came back at about 37.3%. That result led to additional imaging — an MRI, followed by an ultrasound and biopsy — which ultimately revealed breast cancer in both breasts. Munn has since credited that risk assessment with helping lead to her diagnosis. Tools such as the Tyrer-Cuzick model estimate breast cancer risk using factors beyond a mammogram, including family history, age, reproductive history, breast density, and other personal risk factors. A screening test tells you what can be seen today. A risk assessment asks a different question: how closely should we be looking in the first place?

🧬 New @McCulloughFund report | 5/6 Beyond killing cancer cells directly, ivermectin and mebendazole may also help the immune system find and attack them, from two different sides. 👇 🔹Ivermectin (mouse breast tumors): triggers immunogenic cell death, draws in T cells, and depletes MDSCs and regulatory T cells 🔹 Mebendazole: activates innate immunity, shifting macrophages into tumor-fighting (M1) mode and boosting natural killer cell activity 🔹 Together they could engage both arms of antitumor immunity.
The @McCulloughFund just released the most comprehensive review to date on the anticancer mechanisms of ivermectin and mebendazole. Let’s break down one group of mechanisms at a time. Resistance and Dissemination 🔸One of the biggest problems with chemotherapy is the fact that cancer cells can become resistant to the treatment and continue to spread 🔸Ivermectin and Mebendazole fights both problems. They turn off the pumps that "spit" chemotherapy out of the cell, shrink the population of the toughest “stem-like” cancer cells, cut off the blood vessels that feed new tumors, and make the remaining cancer cells more sensitive to regular chemo. 🔸They also slow down the ways cancer invades nearby tissue and spreads to other organs by: 🔹Suppressing the Wnt/β-catenin–integrin β1/focal adhesion kinase (FAK) pathway 🔹Inhibiting epithelial–mesenchymal transition (EMT) 🔹Blocking neutrophil extracellular trap (NET) formation by binding gasdermin D @twc_health @YaleSPH @AmericanCancer

I just reviewed the DEFUSE proposal, and to my astonishment, Baric and Shi do NOT once mention RaTG13 in the document. In my twenty years of doing true crime investigations, I have often found that what is omitted from documents often speaks louder than what is included in them. Given that it was almost certainly Baric who wrote the technical language in the DEFUSE proposal, it strikes me as very strange that he didn’t once mention RaTG13 as a shining example of a SARS Bat Coronavirus of concern for the work he proposed. It was a naturally occurring virus with some affinity to the human ACE-2 receptor, found in a mine in which 6 men had fallen ill with pneumonia. Jim Haslam has raised the suspicion that Shi published the RaTG13 genome (closely related to SARS-CoV-2, only without the decisively import furin cleavage site) as a insider’s message to Baric—something along the lines of, “My team at the WIV did NOT insert the furin cleavage site, so don’t even think about blaming us.” open.substack.com/pub/peterm…

UPDATE: The controversial U.S.-backed hepatitis B vaccine trial involving 14,000 newborns in Guinea-Bissau will not move forward. The $3.2 million study, which we previously covered, faced international scrutiny over its design and the ethics of delaying vaccination for some infants. Now, lead researcher Frederik Schaltz-Buchholzer has confirmed that the trial will not proceed after the team failed to secure the necessary government approval. The decision follows months of controversy surrounding the proposed research.
