10. Julie Gibson Clark



This 55-year-old single mom makes less than $100k per year and is reverse aging without spending millions. Here’s her daily routine.

Unlike the tech millionaires using extreme anti-aging protocols like spending up to $1,000 an hour to see a rejuvenation doctor, Clark’s secret is somewhat ordinary. After all, she makes less than six figures a year and cannot afford to spend her savings trying to live forever since she will need enough to sustain her into extreme old age. She spends $27 a month on a gym membership and $79 a month on a supplement subscription from NOVOS, the company whose trial she entered and worked with to submit her results to the longevity leaderboard. (Also featured in Fortune, Business Insider and NewsNation)

Julie and Amy aren’t the only NOVOS customers making waves. Lil Eskey, a 41-year-old female, is also outperforming Bryan Johnson. In this case, Lil is ranked for her improvement in her pace of biological aging in a before-after NOVOS comparison. Lil slowed her biological pace of aging down from 0.925 per year before NOVOS to just 0.77 after only 6 months of taking NOVOS Core and NOVOS Boost (Julie also had impressive results according to this metric, slowing her pace of aging from 0.765 to 0.65 after 6 months of NOVOS).

And it’s not only women. Men like Rick Chiovarelli, who’s in 7th place on the global leaderboard, have slowed their biological pace of aging by more than 21% to just 0.785 per year.

If you have been diagnosed with cancer, or have a loved one that is suffering from cancer, chances are you have heard about the Joe Tippens Cancer Protocol. The Fenbendazole Cancer Protocol has been gaining rapid interest over the past years following some fenbendazole advanced cancer success stories . We have seen tremendous demand for some sort of guide on how to use fenbendazole for cancer as there is also tremendous confusion both from the healthcare and non-healthcare communities. Joe Tippens founded the protocol (1) after he was told a story about a scientist at Merck Animal Health that had been performing cancer research on mice. The research included injecting different types of cancers into different mice body parts. The scientists discovered, through trial and error, a product in their canine product line, fenbendazole, that was batting 1.000 in killing these different cancers in the mice.

Best Ivermectin Dosage for Humans with Cancer or Different Cancer Types (2025)

By Editorial Team -
Image
Introduction This article discusses dosage considerations and key factors regarding the use of ivermectin in cancer treatment. Commonly available information about ivermectin dosages is often inaccurate when applied to potential cancer-related uses.  Many sources cite standard dosages recommended by Merck for treating parasitic infections, rather than dosages studied specifically in the context of cancer research. The anti-parasitic dosage is not as effective for people looking for a dosage against cancer. Dosage will need to be adjusted according to cancer type and stage. Ivermectin dosage should be based on ivermectin cancer studies. Multiple factors are considered including studies including ivermectin for cancer, anecdotal studies and case series, the aggressiveness of the cancer type and the cancer stage. Cancer dosage estimation can be adjusted based on the time that a person has to beat cancer or its risk to the patient - this includes both the cancer type and whether the ca...

DMSO 101: Benefits, Uses, Dosage and Side Effects (2025)

By Editorial Team -
Image
DMSO is a medical abbreviation for DiMethyl SulfOxide. Modern medicine often sidelines "miracle" drugs that work too well. Despite decades of evidence showing that the naturally occurring chemical Dimethyl Sulfoxide (DMSO) is a remarkably safe and versatile treatment for a range of challenging conditions — such as strokes, head trauma, spinal cord injuries, dementia, and even Down Syndrome (63) — it has been largely overlooked. This sidelining is particularly remarkable as DMSO is also one of the most effective treatments for acute and chronic pain, musculoskeletal injuries, and chronic degenerative conditions (e.g., arthritis). DMSO, Nature’s Healer DMSO is a powerful, natural compound with several unique properties that make it an incredibly versatile healing agent: Rapid absorption —  When applied to the skin or ingested, DMSO quickly spreads throughout the body. ...

Transcription (emphasis 2SG - 2nd Smartest Guy):  Hi, everyone. Welcome to another episode of 15 minutes with Dr. Makis, my new hard hitting medical podcast. This episode is about  fenbendazole  and cancer.  I will give you the most comprehensive review of the use of  fenbendazole  in cancer there is.   Fenbendazole  is an antiparasitic.  It is a dog dewormer, has been used It's been used as an antiparasitic since the 1960s,   and it has been shown to have extensive anti cancer activity.    Now, it's not FDA approved for use in humans. There is a version of it that is almost identical that is approved for use in humans by the FDA, and it's called mebendazole. (2SG: Mebendazole is BigPharma’s money grab whereby they removed a molecule from fenbendazole such that they could egregiously up-charge for a slightly inferior compound based on a bogus patent). I will do a separate video for mebe...

Transcription (Video below): Hi, everyone. Welcome to another episode of 15 Minutes with Dr. Makis, my new hard-hitting medical podcast. It is now pretty well established that Pfizer and Moderna COVID-19 mRNA vaccines cause extremely aggressive cancers called turbocancer. They are gaslighting us about this. The medical establishment is burying their head in the sand. They're pretending that this phenomenon doesn't exist. 0:29 We've got a Wikipedia entry that quotes an oncologist in the States, Dr. David Gorski, who has received funding for his blog from child sex trafficker Jeffrey Epstein. He's written big articles claiming that this is a made-up phenomenon. But what you will find on social media is that thousands of people and their family 0:51 members are repo...
