Hormonal

Allergies

"With allergies, it’s similar to autoimmunity except not so serious, estrogen changes the immune function, tends to shrink the thymus gland, and increase antibody production without the guidance of the thymus cells." - Ray Peat

Problem	Mechanics	Solution	Dose
Thymus shrinkage	Reduces T-cell production, weakening immunity and increasing autoimmunity risk. Hypothyroidism leads to elevated estrogen/cortisol which causes thymus atrophy over weeks.	Address hypothyroidism to maintain thymus function, potentially using thyroid hormone support.

Sexual

Homosexuality

Problem	Mechanics	Solution	Dose
Causes
Prenatal Stress	Positive correlation between prenatal stress and male homosexuality in Germany post-World War II, with 73% of stressful events linked to war influences or unwanted pregnancies.
Prenatal Stress + Nicotine exposure in the womb	Significant feminizing effect of stress on the sexual orientation of male offspring in 1st trimester, 2nd trimester stress increased the likelihood of lesbianism in female offspring.
Prenatal stressors + immune responses	Trigger epigenetic changes like histone acetylation, silencing genes for masculinization and increasing homosexuality risk, with effects persisting across generations via non-coding RNAs
Severe maternal stress during pregnancy	Especially in the second trimester may alter the sexual orientation of male offspring, based on retrospective reports from 283 mothers and their children.
Different hormonal reacion - estrogen feedback loop	They gave straight men lutinizing hormone causing a rise in estrogen then come down, gay men and trannies had positive feedback loop rasiing estrogen in turn raising lutinizing hormone.
Prenatal exposure to sex steroids	Eg. testosterone organizes human sexual orientation, with higher levels promoting attraction to females and lower levels to males, supported by studies on conditions such as congenital adrenal hyperplasia.
Childhood Sexual Abuse (CSA)	In a cohort of 327 homosexual and bisexual men, 35.5% reported CSA,
Childhood Sexual Abuse (CSA)	Among 1,001 adult homosexual and bisexual men attending STD clinics, 37% reported coerced or forced sexual contact before age 19 (94% with male partners)
Childhood Sexual Abuse (CSA)	Gay men and lesbian women reported significantly higher rates of childhood molestation than heterosexuals, with 46% of gay men (vs. 7% of heterosexual men).
Childhood Sexual Abuse (CSA)	2.5 times higher odds of CSA, 1.7 times higher odds of parental physical abuse,
Childhood Sexual Abuse (CSA)	1,500 adults, 83% of LGBQ individuals reported adverse childhood experiences (ACEs) like sexual/emotional abuse.
Prenatal androgen exposure	Lower prenatal testosterone correlates with smaller 2D:4D finger ratios in gay men (feminized) and larger ratios in lesbians (masculinized), linking hormone levels to brain organization for sexual partner preference, as replicated in CAH studies where high androgens increase lesbianism risk by 30–40%.
Gene- and environment-dependent neuroendocrine etiogenesis of homosexuality and transsexualism
Thyroid hormone disruptions	Prenatal thyroid imbalances (e.g., via autoimmune issues on chromosome 14) alter sex steroid metabolism, increasing homosexuality incidence, as thyroid glands act as "sexual organs" influencing fetal brain dimorphism.
Genetics	There is no gay gene.
Brain Differentiation	Alcohol helps (temp), increase CO2, Magnesium, increase mitochondrial function - salt, B3, Coffee, antiinflamatory - Progesterone and DHEA, Thyroid supports GABA by producing CO2, neurosteroids, and ATP, diet- avoid excess phosphate, lactic acid, and iron.
Hypothalamic differences	Gay men's INAH-3 nucleus (third interstitial nucleus of the anterior hypothalamus) is smaller and more female-like, formed prenatally under androgen influence, correlating with sexual orientation.
Amygdala and auditory processing	Homosexual individuals show sex-atypical amygdala connectivity and otoacoustic emissions (inner ear responses), suggesting prenatal hormones organize neural circuits for attraction, with lesbians displaying hyper-masculinized auditory evoked potentials.
Suprachiasmatic nucleus (SCN) size	Larger SCN in gay men (similar to women) indicates prenatal estrogen/testosterone imbalances affect circadian and sexual dimorphic brain regions, influencing partner preference circuits.
Estrogen Response	A single estrogen dose created a positive feedback loop in homosexual men, unlike heterosexuals, supporting brain differentiation differences.
Endocrine Response	ACTH injection revealed abnormal adrenal hormone ratios in female homosexuals and transsexuals, linked to a 21 hydroxylase deficiency.
Baseline Cortisol	Transsexual women showed higher baseline cortisol levels than homosexual or heterosexual women.
Hyperprolactinemia	Stress-induced high prolactin levels may predispose male infants to homosexual tendencies, may prevent brain masculinization, reversible with dopamine agonists like lisuride.	Lisuride
Hormone Influence	Estrogen and melatonin increase prolactin, while progesterone reduces homosexual activity; melatonin gummies may contain excessive levels.
Orgasm and Hormones	Estrogen-driven states and progesterone/vitamin E deficiencies may lead to unfulfilling orgasms, influencing novelty-seeking behaviors.
Conversion Therapy Case	DHEA treatment corrected homosexual tendencies and anti-social behaviors in two teenagers.	DHEA, beautiful imagery of the sexes, and progesterone

Inability to climax

"Having an orgasm without enough vitamin E would be like sneezing without first inhaling, the effect is a series of very small, quick sneezes." - Ray Peat

Masters, the sex researcher, recently mentioned that

quite a few women have been losing their ability to have an orgasm after being on the pill for 18 months or longer, and

For certain nerve systems, both taking vitamin E and having an orgasm might be compared to taking a good deep breath.

Tocontinue the analogy between breathing and orgasm. having an orgasm without enough vitamin E would be like sneezing without first inhaling. Some people really do this, and the effect is a series of very small, quick sneezes. That is.

Early Menarche

Problem	Mechanics	Solution	Dose
Fatherlessness	Not having a father	Get dad	1 father
High PUFA diet
High stress enviroment
Early Menarche Risks	Early menarche (onset <13 years) increases risks of breast cancer, obesity, diabetes, liver disease, depression, eating disorders, substance abuse, and autism in offspring due to elevated estrogen, growth hormone, and prolactin from perceived environmental stress and resource scarcity. Rising tissue iron concentration post-growth cessation exacerbates these risks. (Martinez, 2020 - Lyall et al., 2010 - Villamor et al., 2011 - Barrero et al., 2022 - Zacharias et al., 1964)	Increase progesterone and thyroid levels with a thermogenic diet, reduce environmental stress, and optimize light exposure and vitamin D to delay menarche and extend differentiation.	- Thermogenic diet: Adjust based on individual response (e.g., frequent meals with 50% carbs, moderate protein/fat). - Vitamin D: Sufficient levels to delay by ~1 year (specific dose not quantified, consult health professional). - Light optimization: Natural sunlight exposure, avoid artificial light impairment.
Declining Core Body Temperature	A steady decline in core body temperature since the Industrial Revolution (linked to metabolic slowdown) correlates with earlier menarche, possibly due to reduced thyroid function and increased stress responses, accelerating puberty.	Maximize thermogenicity through diet (e.g., sugars, saturated fats) to boost metabolism and thyroid activity, countering the temperature drop and delaying menarche.	- Thermogenic diet: Start with small amounts (e.g., 1 tsp coconut oil) and build to 1-2 tbsp/day, paired with 200-400g carbs/day from fruits/juice.
Environmental Stress Impact	Stressful, resource-limited environments (e.g., urban vs. rural 17th-19th century data: 17-22 years menarche in peasants vs. 13-15 in townspeople) trigger hormonal shifts (high estrogen/prolactin) to hasten puberty, linked to poor health outcomes. (Tanner (historical data) - Roberton, 1846 - Guarinoni, 1610)	Lower environmental stress by improving light exposure (sunlight vs. artificial), reducing iron overload, and supporting a high-metabolism state to mimic less stressful conditions.	- Light exposure: 15-30 min morning sunlight. - Iron management: Avoid excess (e.g., limit fortified foods), consider donating blood if applicable. - Diet: High progesterone/thyroid foods (milk, eggs).
Light Perception Impairment	Impaired light perception (e.g., in blind individuals) moderately advances menarche by disrupting circadian rhythms and hormonal regulation, increasing estrogen dominance. (Barrero et al., 2022 - Zacharias et al., 1964)	Optimize natural light exposure and minimize artificial light (e.g., blue light at night) to regulate puberty timing via circadian alignment.	- Light optimization: Morning sunlight (10-15 min), blue-light-blocking glasses at night.
Vitamin D Deficiency	Deficiency in vitamin D accelerates menarche, while sufficiency delays it by about one year, likely due to its role in hormonal balance and thyroid support. (Villamor et al., 2011)	Ensure adequate vitamin D intake through diet or sunlight to support delayed menarche and reduce associated disease risks.	- Vitamin D: Sufficient levels (consult health professional for dosing, e.g., 1000-4000 IU/day typical range).

Grey hair

“I would rub vitamin A and vitamin E (sometimes with DHEA), or a solution of copper acetate, into the skin around the white hairs. Within a few weeks, the bottom of one of the white hairs had begun to darken” - Ray Peat.

Problem	Mechanics	Solution	Dose
Progressive loss of hair pigmentation due to T3 deficiency	low T3 → prolonged telogen phase → reduced melanocyte stem cell activity → decreased melanin transfer to keratinocytes → graying/white hair	Topical or systemic triiodothyronine (T3) → shortens telogen phase → induces early entry into anagen phase → stimulates follicular melanocytes → repigmentation of gray hair Excess or restoration of T3 shortens telogen, stimulates keratinocyte growth, reactivates dormant melanocytes, and restores melanin productionr	Human cases (systemic): • IV T3 + levothyroxine during myxedema coma treatment (T3: 25 μg every 8 h → 12.5 μg every 8 h) • Oral levothyroxine adjustment leading to transient high-normal or elevated T3
Mitochondrial depletion	DGUOK depletion → ROS accumulation → melanocyte stem cell exhaustion	N-acetylcysteine (NAC) to reduce ROS and restore MeSCs	NAC (0.25–2.5 mg/mL in drinking water)
Reduced melanin synthesis due to low thyroid hormone	Thyroid hormone deficiency (low T3) → impaired melanin production in melanocytes	Thyroid hormone T3 to restore melanin synthesis	T3 (adjust to 2.5–5 mcg/day orally, per symptom monitoring)
Oxidative damage to melanocytes	Excess reactive oxygen species (ROS) from poor diet/stress → melanocyte depletion	Vitamin C as an antioxidant to reduce ROS and protect melanocytes	Vitamin C (500–1000 mg/day)
Oxidative stress-induced melanocyte loss	Excess ROS and lipid peroxidation → accelerated melanocyte death	Vitamin E as an antioxidant to mitigate oxidative stress	Vitamin E (200–400 IU/day)
Insufficient micronutrients for melanin production	Low copper/iron from poor diet → reduced tyrosinase activity and melanin synthesis	Nutrient-dense diet (e.g., liver) to supply copper	Liver (100g 2x/week)
Melanin destruction	Severe stress or injected cortisone destroys melanin (causes local or sudden greying)	Oppose excess cortisone by supplementation	Progesterone, pregnenolone, DHEA,
Iron Overload	Iron accumulation with aging + oxygen wastage; iron becomes highly toxic when oxygen is deficient	Greatly reduce dietary iron	Very low-iron diet (mostly milk, cheese, eggs, citrus fruit; very little meat) for several weeks
Copper deficiency	Copper is needed to keep iron non-toxic and for melanin synthesis)	Increase copper intake	Cooked eggs in copper pan daily; topical dilute copper acetate rubbed into skin around white hairs
Excess molybdenum	Displaces copper (turns black sheep’s wool white)	Avoid high molybdenum
Mineral defficiency	Wrong pattern or deficiency of trace minerals (Japanese study: removing all trace minerals → white hair)	Supply the specific trace-mineral pattern associated with the desired color
Youth hormone defficiency	Low pregnenolone/progesterone/DHEA with age or stress	Supplement pregnenolone and DHEA
Oxidative stress	Low antioxidant protection when oxygen is low	High-dose vitamin A (retinol) and vitamin E	Oral: large amounts of preservative-free vitamin A daily Topical: vitamin A + vitamin E (sometimes with DHEA) rubbed around white eyebrow hairs on alternate days

Ménière's disease

“Hypothyroidism leads to increased estrogen and nitric oxide, and a decreased serum osmolarity (increased dilution of body fluids) and hyponatremia. Salt, magnesium, calcium, aspirin, antihistamine, progesterone, tetracycline (or minocycline, doxycycline) and thyroid can correct the fluid imbalance.” - Ray Peat

Problem	Mechanics	Solution	Dose
High prevalence of hypothyroidism in patients with Ménière’s disease (32% of MD patients vs. 4% of controls	Hypothyroidism contributes to Ménière’s through altered endolymph production or regulation, possibly due to thyroid hormone’s influence on inner ear fluid homeostasis. Thyroid dysfunction could exacerbate or trigger symptoms like vertigo, hearing loss, and tinnitus.	Fix underlying thyroid issues or supplement T3/T4.
