Well worth knowing!

🛑IVERMECTINE ET FENBENDAZOLE METTENT FIN AU CANCER 🎯CONFIRMÉ : L’épidémiologiste Nicolas Hulscher affirme que des rémissions complètes de cancers de stade IV à l’aide de médicaments antiparasitaires sont déjà documentées dans la littérature scientifique évaluée par les pairs. Selon lui, des centaines d’études montrent que l’ivermectine et le fenbendazole activent plus de 12 mécanismes anticancéreux différents et agissent contre plus d’une douzaine de types de cancer. Parmi les travaux les plus marquants cités par Hulscher figure un rapport de cas publié dans *Case Reports in Oncology*. Là, trois patients atteints de cancer métastatique de stade IV sont décrits, qui ont obtenu une rémission complète documentée par imagerie et marqueurs tumoraux : 📌Une femme de 83 ans atteinte d’un cancer du sein ayant métastasé au foie, aux poumons et aux os. Après traitement, le scanner PET a montré une rémission complète, et elle n’a présenté aucune récidive en près de trois ans. 📌Un homme de 75 ans atteint d’un cancer de la prostate métastatique aux os. Son PSA est tombé à des niveaux indétectables, et les métastases ont complètement disparu. 📌Un homme de 63 ans atteint d’un mélanome BRAFV600+ très avancé. Son ADN tumoral circulant est passé de 123 à 0 en moins de deux mois, avec une rémission confirmée. De plus, une récente revue systématique a analysé 26 études portant sur 36 patients réels traités à l’ivermectine. Aucun effet indésirable grave n’a été signalé, et des améliorations cliniques ont été observées même dans les cas de leucémies et lymphomes, beaucoup d’entre eux tout en continuant à recevoir une chimiothérapie conventionnelle. Les scientifiques alternatifs expliquent que ces médicaments attaquent le cancer de multiples façons : ils déstabilisent les microtubules, induisent l’apoptose programmée, bloquent la voie mTOR, coupent l’approvisionnement en glucose des cellules tumorales, inhibent la formation de nouveaux vaisseaux sanguins et éliminent les cellules souches cancéreuses. Tout cela avec des médicaments qui coûtent quelques centimes et qui sont utilisés chez les humains et les animaux depuis des décennies. Alors que la médecine conventionnelle investit des milliards dans des thérapies à coût élevé, sur les réseaux sociaux, des milliers de patients partagent déjà des témoignages personnels : des tumeurs qui rétrécissent ou disparaissent, des marqueurs qui se normalisent, et des chirurgies qui finissent par être annulées. La question qui déferle sur le monde est de savoir si cela représente la plus grande suppression médicale de l’histoire ou la découverte la plus importante du XXIe siècle. La communauté scientifique dissidente exige des essais cliniques contrôlés avec urgence. Pour de nombreux patients atteints de cancers en phase terminale, le temps a tout simplement expiré. Qu’en pensez-vous ? Faites un RT et partagez cette information avant qu’elle ne disparaisse, car elle pourrait sauver de nombreuses vies. Vos amis ou votre famille qui luttent contre le cancer doivent lire cela aujourd’hui. SUIVEZ-MOI, LA PROCHAINE INFO VA ÊTRE CHOQUANTE

🚨🚨 Después de años de investigación, el Dr. William Makis comparte el protocolo censurado de dosificación de IVERMECTINA para la lucha contra el cáncer... Según el Dr. Makis, para la mayoría de los cánceres, incluidos el de mama, colon, pulmón, páncreas, riñón, gástrico y las leucemias, se recomienda una dosis inicial de 1 mg por kg de peso corporal por día... Para una persona de 60 kg, esto equivale a 60 mg diarios: - Cinco pastillas de 12 mg - O 6ml de líquido (aprox. una cucharadita + 1ml) La evidencia de eficacia es convincente y depende de la dosis: - El Dr. Shankara Chetty observó cómo el PSA de un paciente con cáncer de próstata disminuía de 89 a 11 con una dosis de 45 mg/día. - Un caso de la Dra. Tess Lawry mostró una caída del CA125 (marcador de cáncer de ovario) de 288 a 22 con solo 0,2 mg/kg. - Un estudio a largo plazo de Castro en niños con leucemia no mostró efectos secundarios después de 6 meses con 1 mg/kg. En el caso de cánceres agresivos (páncreas, cerebro), la barrera hematoencefálica puede requerir una dosis mayor. El Dr. Makis cita: - Colega del Dr. Landrito con cáncer de vesícula terminal: el cáncer desapareció después de 14 meses con 2 mg/kg/día. - La dosis más alta documentada es de 2,5 mg/kg (Dr. Chetty), con solo efectos secundarios visuales transitorios que se resolvieron. La oncología convencional no ofrece esto. ¿Por qué? La ivermectina es genérica, no tiene patente y no es rentable. Por consiguiente, no hay ensayos clínicos financiados... "Usar ivermectina para el cáncer es, sinceramente, muy sencillo. Es un fármaco sumamente seguro"... Su recomendación más importante para quienes tienen dificultades es comenzar con 1 mg/kg/día. Se puede tomar durante muchos meses, incluso más de un año, con un excelente perfil de seguridad basado en evidencia anecdótica a largo plazo, nada que perder...

VOCÊ SABIA? Astaxantina é 6000 vezes mais potente que a vitamina C em combater o estresse oxidativo. O que é astaxantina e por que falam tanto dela? A astaxantina é um carotenoide natural (pigmento vermelho-alaranjado) encontrado principalmente em microalgas (como a Haematococcus pluvialis). É o que dá aquela cor rosa/vermelha característica ao salmão selvagem, por exemplo. Ela é considerada um dos antioxidantes mais potentes da natureza e o número 6000 vezes mais forte que a vitamina C, aparece em dezenas de artigos científicos, revisões e sites de suplementos. Esse valor vem de estudos que medem a capacidade de neutralizar o oxigênio singlete (um tipo muito reativo de radical livre/ROS – espécies reativas de oxigênio). Nesses testes, a astaxantina mostra uma potência muito superior comparada a outros antioxidantes. Comparações comuns citadas em estudos e revisões: - Até 6000 vezes mais potente que a vitamina C (ácido ascórbico) contra oxigênio singlete. - Até 100–550 vezes mais potente que a vitamina E (alfa-tocoferol). - Até 40–110 vezes mais potente que o betacaroteno. - Até 770–800 vezes mais potente que a coenzima Q10. Esses números são baseados principalmente em testes de extinção de oxigênio singlete e scavenging de radicais livres em sistemas livres de células ou membranas modelo. Um artigo de revisão bem citado (Bjørklund et al., 2022, no PMC) e vários outros em ScienceDirect confirmam essa faixa. - A astaxantina é lipossolúvel, atravessa membranas celulares com facilidade (inclusive barreira hematoencefálica e da retina), protege tanto a parte interna quanto externa das membranas lipídicas, e não se torna pró-oxidante facilmente. Por isso, em contextos como proteção da pele contra UV, redução de inflamação, saúde ocular, cerebral e muscular, a astaxantina frequentemente mostra resultados superiores ou complementares à vitamina C em estudos clínicos e pré-clínicos. Muitos especialistas dizem que os dois se complementam muito bem. Benefícios mais estudados da astaxantina - Proteção da pele (melhora elasticidade, diminui rugas finas). - Saúde ocular (protege retina, ajuda em fadiga visual). - Suporte cardiovascular e cerebral (reduz inflamação e estresse oxidativo). - Melhora na recuperação muscular e endurance. - Ação anti-inflamatória geral. As doses comuns em suplementos variam de 4 a 12 mg/dia (às vezes até 24 mg em formas lipossomais), e é considerada muito segura. cyanotech.com/pdfs/bioastin/… researchgate.net/publication/28… pmc.ncbi.nlm.nih.gov/articles/PMC96…

This scientist found nattokinase. At 10,800 FU daily, it reversed arterial plaque in 66.5% of patients over 12 months, with no side effects. The rest of the data is even more insane. Researchers tracked 1,062 people with confirmed hyperlipidemia and carotid artery plaque. These weren't just healthy volunteers. Every person had an ultrasound at the start and another after 12 months of daily nattokinase. The study used two dose groups: 3,600 FU and 10,800 FU per day. The low-dose group saw almost no change in their plaque or lipid markers. Even though it was the same supplement for the same amount of time, the dose made the difference. At 10,800 FU, carotid artery plaque shrank by up to 36%. The arterial wall thickness decreased by 21.7% on average. These are physical, structural changes that doctors measured and confirmed on ultrasound. 77.7% of participants showed measurable improvement in arterial wall thickness. 66.5% showed measurable reduction in plaque size. Improvement rates across all markers ranged from 66.5% to 95.4% for the majority of over 1,000 people, not some few lucky responders. The participants lipid results moved in every right direction simultaneously. - Total cholesterol: down - LDL: down - Triglycerides: down - HDL: up No adverse effects were recorded at any point across the full 12 months. Lifestyle also amplified everything. Participants walking more than 5,000 steps daily responded better than sedentary ones, and those with higher BMI saw larger relative improvements, likely because they started from a higher risk baseline where there was more room to move. The study also tested co-administration. Vitamin K2 and low-dose aspirin taken alongside nattokinase produced a synergistic effect, outperforming nattokinase alone across cardiovascular markers. If you're building a stack, that's the combination the data points to. The researchers found the effective range is 6,000 to 12,000 FU daily. Most supplements in Europe are only 2,000 FU. That's a huge gap. The data shows 2,000 FU does almost nothing to plaque, while 10,800 FU actually shrinks it. All in all, truly an incredible enzyme.

🚨🚨Uno de los secretos ocultos para no padecer cáncer: protege tus mitocondrias, tu salud está en tus manos... El cáncer no surge de la nada; comienza cuando las mitocondrias de una célula normal se descomponen y dejan de funcionar. La clave para la prevención del cáncer reside en proteger estas células: 1. Optimiza los niveles de vitamina D Mantén niveles sanguíneos de 70–80 ng/mL. La vitamina D es un potenciador mitocondrial que refuerza el sistema inmunitario y mantiene las células funcionando de forma óptima. 2. Aprovecha el poder del ayuno El ayuno intermitente regular, combinado con ayunos periódicos prolongados (como un ayuno de agua de dos días al mes), desencadena la autofagia (el proceso de limpieza natural del cuerpo) que elimina las células dañadas y rejuvenece las mitocondrias. 3. Reduzca los carbohidratos refinados y los almidones Las dietas ricas en carbohidratos son la criptonita mitocondrial. Adopta una dieta baja en carbohidratos para reducir el estrés oxidativo y proteger la producción de energía celular. 4. Consuma alimentos que estimulen las mitocondrias El ajo, la cebolla y las verduras crucíferas (brócoli, col rizada, coles de Bruselas) están repletas de compuestos de azufre que desintoxican y fortalecen las mitocondrias. 5. Evita el exceso de hierro El exceso de hierro —proveniente de suplementos, alimentos fortificados o utensilios de cocina de hierro fundido— acelera el daño mitocondrial. Controla tu consumo para mantener el hierro en niveles adecuados. 6. Haz ejercicio con regularidad El movimiento no solo sirve para estar en forma; es un elixir para las mitocondrias. El ejercicio regular mejora su eficiencia, reduce la inflamación y disminuye el riesgo de cáncer. La ciencia es clara: el cáncer prospera en un cuerpo con mitocondrias débiles. Fortalécelas y construirás una defensa impenetrable... Dr. Eric Berg.

everyone talks about BPC-157 for tendons and gut lining, but that's barely scratching the surface. the rabbit hole goes MUCH deeper for this incredible peptide originally derived from gastric juice: - it reverses dopamine receptor desensitization from chronic stimulant use leading to actual receptor restoration - it counteracts alcohol damage to the liver, stomach, and brain at the same time - it modulates nitric oxide bidirectionally - raising blood pressure when too low, lowering it when too high. - it repairs peripheral nerve crush injuries through VEGF and growth factor upregulation. - it promotes organized collagen deposition instead of scar tissue; better function and appearance post-injury. - it restores gut barrier integrity, which cuts lps translocation into the bloodstream, indirectly resolving neuroinflammation-driven depression and anxiety - it accelerates closure of intestinal fistulas, which almost nothing else does clinically - it protects the gut lining while you're on NSAIDs instead of fighting them - it upregulates VEGF in hair follicles - improved blood supply, better density in diffuse thinning. - it repairs oral and periodontal tissue - documented in dental research almost nobody reads - it is one of the only compounds with legitimate TBI recovery data at the structural level most compounds treat symptoms but BPC-157 repairs the root issue - and when they're fixed and you get off it, the effects stay. because you've fixed them at the root. not medical advice but i theoretically think pretty much anyone would benefit from one 30-day cycle of oral BPC-157... 500mcg (1 cap) daily. i am young and practically at peak health, yet it completely fixed a half-decade old shoulder injury and made me realize i'd been living with a fucked up gut for years. made my mood a lot smoother and obliterated my brain fog to the point i barely even remember what it felt like. life changing. watch out for fake products. they're everywhere. this is what i use, made in a US GMP certified lab and 3rd party tested. full disclosure; these are affiliate links.

Here's hoping this link works for you all. DMSO for eyes, amazing benefits you should not ignore. DMSO Heals the Eyes and Transforms Ophthalmology DMSO's unique therapeutic properties reveal the unifying thread between many different "incurable" eye diseases. A Midwestern Doctor Story at a Glance: • DMSO is an “umbrella remedy” capable of treating a wide range of challenging ailments due to its combination of therapeutic properties (e.g., reducing inflammation, improving circulation, and reviving dying cells). • DMSO has a unique affinity for the eyes, resulting in it (often spontaneously) treating a wide range of visual disorders that frequently cannot be treated with conventional therapeutic options. • DMSO’s ability to restore circulation, revive dying cells, and stabilize misfolded proteins allows it to treat a variety of retinal diseases (e.g., macular degeneration, diabetic retinopathy or retinitis pigmentosa—in some cases reversing permanent blindness), eliminate visual obstructions (e.g., floaters and cataracts), reverse glaucoma or Fuchs’ dystrophy, and restore normal focus (frequently eliminating the need for glasses). • DMSO’s anti-inflammatory and antimicrobial properties allow it to treat dry eyes, inflammatory diseases around the eye (e.g., blepharitis, styes, and psoriasis) or within the eye (e.g., iritis, uveitis, conjunctivitis, keratitis), along with bacterial, fungal, parasitic, or viral eye infections such as shingles. •DMSO’s healing properties also allow it to heal a variety of eye injuries (including severe ones which would otherwise require eye removal), skin issues around the eye (e.g., burns, skin tags, and under-eye bags), and eliminate eye muscle spasms. •This article will review the extensive data demonstrating DMSO’s efficacy for eye diseases, along with an examination of the most common protocols used for them and other natural approaches that also aid in the treatment of common eye disorders. Since 2024, I have been working diligently to present the extensive data that DMSO is a remarkable therapeutic that is uniquely suited to treat many highly challenging medical conditions due to its counteracting many root causes of disease (whereas, in contrast, vaccines cause a myriad of health issues by inducing those key drivers of illness). From this, I’ve compiled a series of articles synthesizing thousands of studies that have shown DMSO effectively treats: • Strokes, paralysis, a wide range of neurological disorders (e.g., Down Syndrome and dementia), and many circulatory disorders (e.g., Raynaud’s, varicose veins, hemorrhoids) • A wide range of tissue injuries, such as sprains, concussions, burns, surgical incisions, and spinal cord injuries • Chronic pain (e.g., from a bad disc, bursitis, arthritis, or complex regional pain syndrome) • A wide range of autoimmune, protein, and contractile disorders, such as scleroderma, amyloidosis, and interstitial cystitis • A variety of head conditions, such as tinnitus, vision loss, dental problems, and sinusitis • A wide range of internal organ diseases. • Many different respiratory disorders, including asthma and COPD • Many different gastrointestinal disorders, such as bowel inflammation, cirrhosis, and pancreatitis • A wide range of skin conditions, such as burns, varicose veins, acne, hair loss, ulcers, skin cancer, and many autoimmune dermatologic diseases. • Many challenging infectious conditions, including chronic bacterial infections, herpes, and shingles. • Many aspects of cancer (e.g., many of cancer’s debilitating symptoms, making cancer treatments more potent, greatly reducing the toxicity of conventional therapies, and turning cancer cells back into normal cells). Since the evidence in those articles (along with one on how DMSO can be synergistically combined with pharmaceuticals and another on how DMSO combines with natural therapies) made a compelling case for the use of DMSO, many readers opted to start using it. amzn.to/4t0TWaR
