Comparison
DHEA vs Testosterone
Side-by-side of DHEA and Testosterone. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
DHEA
DHEA supplement profile: adrenal androgen precursor, typical 25-50 mg dose, DHEA-S targets, evidence for adrenal insufficiency and vaginal atrophy, side effec.
Testosterone
Testosterone replacement therapy for hypogonadism: TRAVERSE 2023 cardiovascular data, cypionate dosing, body composition gains, Schedule III status.
Effects at a glance
DHEA
- •Adrenal androgen precursor; serum DHEA-S declines progressively after the third decade of life
- •OTC dietary supplement in US under DSHEA 1994; prescription in EU, UK, Canada, Australia
- •FDA approved as Intrarosa (6.5 mg vaginal insert) for postmenopausal dyspareunia in 2016
- •Acts as tissue-specific prohormone converted intracrinologically to testosterone and estrogens
- •Best evidence: adrenal insufficiency replacement and vaginal atrophy; weaker on cognition and longevity
- •WADA banned in competitive sport; banned in NCAA, MLB, NFL, IOC settings
Testosterone
- •Primary androgen; FDA approved for hypogonadism with confirmed deficiency and symptoms
- •Testosterone Trials (2016) showed sexual function and bone density improvements in older hypogonadal men
- •TRAVERSE 2023 (n=5,246) found non-inferiority on MACE versus placebo, with higher AF and PE rates
- •Schedule III controlled substance in US; WADA banned in sport
- •Aromatizes to estradiol; converts to DHT via 5-alpha reductase; both metabolites matter clinically
- •Erythrocytosis (HCT above 54%) affects 5 to 25% of users and is the most common dose-limiting effect

Safety profile
DHEA
Common side effects
- acne
- oily skin
- hirsutism (women)
- gynecomastia (men, higher doses)
- irritability
- insomnia
Contraindications
- hormone-sensitive cancer (breast, ovarian, prostate)
- active liver disease
- uncontrolled lipid disorder
- pregnancy and lactation
Interactions
- warfarin: case reports of altered INR; monitor(moderate)
- estrogens (HRT): additive estrogenic effect via conversion; monitor(moderate)
- insulin: may improve insulin sensitivity slightly; monitor glucose(minor)
- anastrozole: may reduce DHEA-derived estrogen; clinical relevance unclear(minor)
Testosterone
Common side effects
- erythrocytosis
- acne
- oily skin
- fluid retention
- increased body hair
- fertility suppression
- injection-site reactions
Contraindications
- active prostate cancer
- active breast cancer
- untreated severe sleep apnea
- untreated severe BPH
- uncontrolled heart failure
- polycythemia at baseline
Interactions
- warfarin: may potentiate anticoagulant effect; monitor INR(moderate)
- insulin: may improve insulin sensitivity; monitor glucose in diabetics(moderate)
- 5-alpha reductase inhibitors (finasteride): blocks DHT conversion; reduces some androgen effects(moderate)
- aromatase inhibitors (anastrozole): lowers estradiol; risk of over-suppression(moderate)
Which Should You Take?
DHEA comes out ahead for most readers on the criteria we weight: 2 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. Testosterone is the right call when one of the conditionals below applies.
- → If your priority is healthspan extension, pick DHEA.
- → If your priority is sexual function, pick Testosterone.
- → If your priority is body composition, pick Testosterone.
Edge case: If you want to avoid controlled substance, DHEA is the more accessible choice.
Default choice: DHEA. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for Testosterone only if your priority sits squarely in the goals it owns above.

Common questions
What is the difference between DHEA and Testosterone?
DHEA and Testosterone differ in category (hormone vs hormone), mechanism, and typical dosing. See the side-by-side table for full details.
Which has a longer half-life, DHEA or Testosterone?
DHEA half-life is 12 hours; Testosterone half-life is 192 hours.
Can you stack DHEA with Testosterone?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
