Comparison
Creatine Monohydrate vs DHEA
Side-by-side of Creatine Monohydrate and DHEA. 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.
Creatine Monohydrate
Creatine monohydrate supplement guide: 3-5 g/day raises phosphocreatine stores, lifts anaerobic output 5-15%, supports lean mass and cognition under sleep loss.
DHEA
DHEA supplement profile: adrenal androgen precursor, typical 25-50 mg dose, DHEA-S targets, evidence for adrenal insufficiency and vaginal atrophy, side effec.
Effects at a glance
Creatine Monohydrate
- •Increases anaerobic strength and power output by ~5 to 15% across multiple training studies
- •Adds ~1 to 2 kg of lean body mass over 4 to 12 weeks, partly intracellular water and partly true tissue gain
- •Improves 1-rep max on bench and squat by ~5 to 10% versus placebo in resistance-trained adults
- •Cognitive benefit appears mainly under sleep deprivation or high mental load, less so in well-rested individuals
- •Saturation reached in ~28 days at 3 to 5 g/day, or ~5 to 7 days with a 20 g/day loading phase
- •No evidence of renal harm in healthy adults across long-term studies; caution in pre-existing severe renal disease
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

Safety profile
Creatine Monohydrate
Common side effects
- water retention
- mild GI upset at loading doses
- weight gain (2 to 4 lb from intracellular water)
Contraindications
- severe renal impairment
Interactions
- caffeine (high-dose acute): mixed data on ergogenic interference; chronic use appears compatible(minor)
- nephrotoxic drugs (NSAIDs, cyclosporine): theoretical additive renal strain in at-risk patients(moderate)
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)
Which Should You Take?
Creatine Monohydrate comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. DHEA is the right call when one of the conditionals below applies.
- → If your priority is strength or hypertrophy, pick Creatine Monohydrate.
- → If your priority is focus or working memory, pick Creatine Monohydrate.
- → If your priority is hormonal optimization, pick DHEA.
- → If your priority is healthspan extension, pick DHEA.
Edge case: DHEA is contraindicated in pregnancy; Creatine Monohydrate is the safer pick if that applies.
Default choice: Creatine Monohydrate. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for DHEA only if your priority sits squarely in the goals it owns above.

Common questions
What is the difference between Creatine Monohydrate and DHEA?
Creatine Monohydrate and DHEA differ in category (supplement vs hormone), mechanism, and typical dosing. See the side-by-side table for full details.
Which has a longer half-life, Creatine Monohydrate or DHEA?
Creatine Monohydrate half-life is 3 hours; DHEA half-life is 12 hours.
Can you stack Creatine Monohydrate with DHEA?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
