6 Key Concepts
SHBG (Sex Hormone-Binding Globulin)
SHBG is a protein that binds to androgenic steroids, including DHT, testosterone, DHEA, and estrogens, with varying strengths. It plays a crucial role in determining the amount of 'free' (unbound) hormones that are biologically active in the body.
Androgen Receptor
The androgen receptor is a gene located on the X chromosome that mediates the effects of androgens like DHEA, testosterone, and DHT in both men and women. The binding of these hormones to the receptor triggers their specific biological actions.
Polycystic Ovarian Syndrome (PCOS)
PCOS is an underdiagnosed condition in women characterized by a combination of androgen excess, insulin resistance, and sometimes polycystic ovaries. Symptoms can include hormonal acne, excessive hair growth (hirsutism), male pattern baldness, and irregular menstrual cycles.
Dopamine Wave Pool
This metaphor describes the ideal balance between dopamine and prolactin levels. The goal is to maintain consistent, moderate dopamine levels ('nice, even waves') to avoid extreme fluctuations that can lead to an undesirable increase in prolactin.
Peptides
Peptides are a diverse group of compounds composed of chains of amino acids. They vary greatly in their safety profiles, with some being very dangerous and others being very safe and even FDA-approved (e.g., insulin, growth hormone). Safe use often requires medical prescription and careful sourcing.
VEGF (Vascular Endothelial Growth Factor)
VEGF is a factor that stimulates the growth of new blood vessels. While beneficial for healing (e.g., BPC-157 increases it), increasing VEGF can pose a theoretical risk for individuals with cancer or a high cancer risk, as it could promote tumor growth, similar to how anti-cancer drugs often inhibit VEGF.
14 Questions Answered
To encourage your doctor to order a comprehensive hormone panel, describe pertinent symptoms such as decreased energy, focus, or athletic performance compared to how you felt at a younger age, as these symptoms can indicate a need for hormonal investigation.
For preventative purposes, it is recommended to get blood tests every three to six months. These tests should ideally include both fasting and non-fasting samples to provide a comprehensive picture.
Caloric restriction can improve testosterone levels if you are obese or have metabolic syndrome. However, in young, healthy, lean men without metabolic syndrome, caloric restriction is likely to decrease testosterone.
If a lean, healthy individual practices intermittent fasting while maintaining caloric maintenance (consuming sufficient calories overall), it is not expected to be detrimental to their hormone health and may even help growth hormone and IGF-1 levels, particularly in older age groups.
Low testosterone can contribute to poor sleep in men. Conversely, starting Testosterone Replacement Therapy (TRT) can sometimes lead to poor sleep, often due to an increased risk of sleep apnea, especially during the initial one to two months of treatment.
For overall health optimization, knowing a woman's testosterone level is as important as knowing her estrogen and progesterone levels. However, for preventing specific pathologies like breast cancer or osteoporosis, estrogen and progesterone levels are more critical to monitor.
Diets rich in plant polyphenols, such as those found in turmeric and black pepper extract, can inhibit the enzyme that converts testosterone to DHT. Individuals with naturally low DHT or less sensitive androgen receptors might consider avoiding highly bioavailable curcuminoids for this reason.
While cannabinoids (THC or CBD) themselves don't directly reduce testosterone, smoked marijuana can increase aromatase activity, which converts testosterone into estrogen. Elevated estrogen then signals the pituitary to produce less LH and FSH, ultimately leading to decreased testosterone.
Testosterone supplementation does not cause prostate cancer. However, normal aging inherently increases the risk of developing prostate cancer, and if a prostate cancer is already present, testosterone will cause it to grow.
Yes, foods containing casein (milk protein) or gluten can act as mu-opioid receptor agonists in the gut, which may lead to an increase in prolactin levels.
There are significant risks associated with GHRH peptides, primarily an increased risk of tumor growth and cancer. High growth hormone levels are linked to a higher incidence of various cancers, similar to observations in type 1 diabetics.
Yes, individuals with cancer or a high cancer risk should likely avoid BPC-157. This peptide increases Vascular Endothelial Growth Factor (VEGF), which promotes blood vessel growth, and could theoretically aid in cancer growth, contrasting with anti-cancer drugs that often inhibit VEGF.
Yes, there are three FDA-approved indications for Melanotan (specifically brimelanotide or PT-141): hypoactive sexual desire disorder in women (and can help men), lipodystrophy, and a rare genetic condition causing hypopigmentation and morbid obesity in children.
Caffeine has a negligible direct effect on hormones such as testosterone or estrogen. Its primary impact on the body is by acting on adenosine receptors, and any hormonal effects are typically indirect, mainly if it disrupts sleep.

9. Individualize Your Diet Approach
Tailor your diet based on your unique genetics and biofeedback (how you feel), recognizing that dietary needs vary significantly among individuals.
10. Engage in Zone Two Cardio Weekly
Aim for a minimum of 150 to 180 minutes of Zone Two cardiovascular exercise per week, as this is a general recommendation for improving health span.
11. Consider Caloric Restriction for Metabolic Syndrome
If you are obese or have metabolic syndrome, implement caloric restriction (including intermittent fasting) to improve testosterone levels and overall health span.
12. Avoid Caloric Restriction if Young and Healthy
If you are young, healthy, and do not have metabolic syndrome, avoid caloric restriction as it can lead to a decrease in testosterone levels.
13. Optimize Growth Hormone Through Fasting
To enhance growth hormone output, especially overnight, consider intermittent fasting or at least avoid eating in the two to three hours before sleep.
14. Address Sleep Issues from Hormonal Causes
If experiencing sleep disturbances like waking at 3-4 AM, investigate potential hormonal causes such as growth hormone deficiency or vasomotor symptoms of menopause/andropause.
15. Monitor Testosterone Levels in Women
For overall health optimization, women should know their testosterone levels, as this is as important as understanding estrogen and progesterone levels.
16. Be Cautious with TRT and Sleep Apnea
If starting Testosterone Replacement Therapy (TRT), be aware of the significantly increased risk of sleep apnea and potential hypersympathetic state, which can disrupt sleep.
17. Avoid Smoked Marijuana for Hormone Health
Refrain from smoked marijuana, as it can increase aromatase activity, leading to higher estrogen levels and a subsequent decrease in testosterone by inhibiting LH and FSH.
18. Limit High Alcohol Intake
Reduce high alcohol consumption, as it, along with other potent GABA agonists, can significantly decrease testosterone levels.
19. Understand TRT and Prostate Cancer Risk
If considering testosterone supplementation, be aware that while it doesn’t cause prostate cancer, it can accelerate the growth of existing prostate cancer, requiring careful individual assessment with aging.
20. Balance Dopamine and Prolactin Levels
Aim for stable dopamine levels to prevent excessive prolactin, as high prolactin can inhibit the release of testosterone from the pituitary.
21. Eliminate Prolactin-Increasing Foods
If concerned about elevated prolactin, consider eliminating foods like casein (milk protein) or gluten, which can act as mu opioid receptor agonists in the gut and increase prolactin.
22. Incorporate Time Apart in Relationships
Purposely build periods of separation into long-term relationships to allow dopamine levels to reset, fostering renewed excitement and connection upon reunion.
23. Plan for Relationship Challenges
Anticipate that relationships will face crises and proactively plan for positive experiences or strategies to navigate these challenging periods effectively.
24. Consult a Doctor for Peptide Use
