A4M Practice Test 2026/2027 | Anti-Aging Medicine Certification Exam Prep
• This practice test contains 200 carefully curated questions mirroring the actual
A4M board exam format, covering all core domains including hormone therapy,
nutrition, longevity medicine, metabolic health, and integrative therapeutics — use
it to identify weak areas and reinforce strong ones.
• Each question includes five answer options (A–E), a highlighted correct answer,
and a detailed EXPERT RATIONALE to deepen your clinical understanding, not just
memorization.
QUESTION 1
Which hormone is most commonly associated with the regulation of the
sleep-wake cycle and antioxidant function in anti-aging medicine?
A) Estrogen
B) Testosterone
C) Cortisol
D) Melatonin
E) DHEA
Correct Answer: D) Melatonin
EXPERT RATIONALE: Melatonin, produced by the pineal gland, regulates circadian
rhythms and is a potent antioxidant. It declines significantly with age, contributing to
sleep disturbances and increased oxidative stress — both hallmarks of aging.
QUESTION 2
,What is the primary anabolic hormone that declines significantly in men after
age 30, contributing to sarcopenia?
A) Cortisol
B) Estrogen
C) Insulin
D) Melatonin
E) Testosterone
Correct Answer: E) Testosterone
EXPERT RATIONALE: Testosterone is the primary male anabolic hormone. After age
30, levels decline approximately 1–2% per year. This decline is associated with muscle
mass loss (sarcopenia), increased fat mass, reduced bone density, and diminished libido.
QUESTION 3
Which of the following best describes the mechanism of caloric restriction in
extending lifespan?
A) Increases mTOR signaling
B) Decreases AMPK activation
C) Promotes glycolysis over oxidative phosphorylation
D) Increases IGF-1 levels
E) Activates AMPK and inhibits mTOR pathways
Correct Answer: E) Activates AMPK and inhibits mTOR pathways
EXPERT RATIONALE: Caloric restriction activates AMPK (AMP-activated protein
kinase) and inhibits mTOR (mechanistic target of rapamycin), promoting autophagy,
reducing oxidative damage, and extending lifespan in multiple model organisms.
QUESTION 4
,Which telomere-related enzyme is primarily responsible for maintaining
telomere length in stem cells?
A) DNA polymerase
B) RNA polymerase
C) Helicase
D) Telomerase
E) Topoisomerase
Correct Answer: D) Telomerase
EXPERT RATIONALE: Telomerase is a ribonucleoprotein enzyme that adds repetitive
nucleotide sequences to telomere ends. It is highly active in stem cells and germ cells,
preserving telomere length and thereby delaying cellular senescence.
QUESTION 5
A 55-year-old woman presents with fatigue, weight gain, cold intolerance, and
dry skin. Which lab finding is most consistent with her condition?
A) Low TSH, high T4
B) Normal TSH, low T3
C) High TSH, low free T4
D) Low DHEA, high cortisol
E) High estrogen, low progesterone
Correct Answer: C) High TSH, low free T4
EXPERT RATIONALE: This clinical picture is classic for hypothyroidism. Elevated TSH
indicates the pituitary is attempting to stimulate an underperforming thyroid. Low free
T4 confirms insufficient thyroid hormone production.
QUESTION 6
, Which dietary pattern has the most robust evidence for reducing all-cause
mortality and cardiovascular disease in aging populations?
A) Ketogenic diet
B) Carnivore diet
C) Low-fat diet
D) Mediterranean diet
E) Paleo diet
Correct Answer: D) Mediterranean diet
EXPERT RATIONALE: The Mediterranean diet, rich in olive oil, vegetables, legumes,
whole grains, fish, and moderate red wine, has extensive evidence including the
PREDIMED trial demonstrating significant reductions in cardiovascular events and all-
cause mortality.
QUESTION 7
What is the primary role of DHEA in anti-aging medicine?
A) Direct anabolic muscle building
B) Stimulation of thyroid hormone synthesis
C) Inhibition of cortisol at cellular level
D) Regulation of the renin-angiotensin system
E) Precursor to androgens and estrogens with immune-modulating effects
Correct Answer: E) Precursor to androgens and estrogens with immune-
modulating effects
EXPERT RATIONALE: DHEA (dehydroepiandrosterone) is the most abundant
circulating adrenal steroid. It serves as a precursor for both androgens and estrogens
and modulates immunity, mood, and metabolism. Levels peak in early adulthood and
decline with age.
