◐Partially SupportedBlood work is not necessarily a game-changing aspect for optimizing performance in endurance athletes focused on metrics like Ironman times.

✕Not SupportedMany TRT clinics may have incompetent treatment protocols due to a lack of understanding or profit focus.

◐Partially SupportedDoses between one and two milligrams weekly of semaglutide can achieve benefits with faster titration than in clinical trials.

✕Not SupportedTestosterone therapy is generally not recommended for men who wish to maintain fertility or testicular size.

✕Not SupportedPellet implants for hormone therapy are generally avoided due to control and procedural issues, especially in men.

✕Not SupportedEstradiol levels below 25 pg/mL during testosterone therapy should be avoided.

◐Partially SupportedBio-identical estrogen and micronized progesterone are used in current hormone therapy for women.

◐Partially SupportedInitiating estrogen therapy at the onset of or before menopause leads to good outcomes, whereas initiating it in the middle to tail end of menopause can lead to bad outcomes.

◐Partially SupportedOral estrogen, unlike topical estradiol, increases blood coagulability.

✕Not SupportedTestosterone may help with insulin resistance, but using it solely for this purpose is a 'waste' of its potential benefits.

✕Not SupportedThe use of supraphysiological doses of testosterone or anabolic steroids like Anavar in young men for cosmetic effects is not supported by data and is distinct from treating hypogonadism.

✕Not SupportedPeople may use hormone replacement therapy as a crutch, neglecting essential rehabilitation or lifestyle changes.

✕Not SupportedTypical TRT clinics often administer excessive anastrozole alongside testosterone, which can lead to patients feeling unwell.

✕Not SupportedHigh blood pressure increases the risk of all-cause mortality by 20-25%.

◐Partially SupportedThe adverse cardiovascular effects of fen-phen could have been avoided by using the alternative enantiomer of the drug.

◐Partially SupportedPeter Attia achieved a peak physique at age 38 while overtraining and experiencing low testosterone.

◐Partially SupportedDietary intervention alone is insufficient to achieve an ApoB level of 30 mg/dL.

✕Not SupportedThe headline that HRT increases breast cancer risk by 27% is based on an inappropriate context, as the absolute risk increase was only 0.1%.

◐Partially SupportedMaintaining functional capacity in the 'marginal decade' (the last decade of life) is a key aspect of healthspan.

◐Partially SupportedTraining for a long-term objective, like an athletic event or one's 'marginal decade', requires a clearly defined goal.

◐Partially SupportedThe concept of the 'marginal decade' can inform daily behaviors and protocols for improving healthspan.

◐Partially SupportedOral contraceptives with very low synthetic estrogen are sometimes used for symptomatic control in premenopausal women.

◐Partially SupportedA cholesterol-lowering drug from the early 1960s was pulled from the market in the late 1960s because cardiovascular events increased despite cholesterol reduction.

◐Partially SupportedCycling testosterone on and off, or alternating between testosterone and HCG for eight-week periods, can be used to manage TRT.

◐Partially SupportedA typical starting dose for Clomid is 50 milligrams three times a week, which can increase FSH and LH and lead to increased testosterone production.
