Dehydroepiandrosterone Sulphate
Hormones marker
DHEA-S
Dehydroepiandrosterone Sulphate
Category: Hormones
Unit: umol/L
Adrenal androgen precursor. Most abundant circulating steroid. Declines with age. Reflects adrenal androgen production.
PED Notes
Exogenous AAS suppress HPTA but DHEA-S is primarily adrenal, so it may remain relatively stable on cycle. Low DHEA-S can indicate adrenal insufficiency or chronic stress. Some athletes supplement DHEA as a mild androgen precursor during PCT.
When LOW (<2.2 umol/L):
- May indicate: adrenal insufficiency, chronic stress/cortisol elevation, ageing (DHEA-S peaks at 20-30 and declines ~2% per year), overtraining
- DHEA-S is the most abundant circulating steroid and serves as a precursor to both androgens and estrogens
Supplementation (for low DHEA-S):
- DHEA -- 25-50mg/day (morning, with fat-containing meal)
- Start at 25mg/day and retest after 6-8 weeks; increase to 50mg only if still low
- Higher doses (>50mg/day) can elevate estradiol and DHT -- monitor E2 and DHT if using >25mg
- DHEA converts to androstenedione, then to testosterone and estradiol -- can raise both
- In PCT: 25-50mg/day may provide mild androgenic support while HPTA recovers
Supporting supplements:
- Vitamin C -- 1-2g/day (supports adrenal function)
- Pantothenic Acid (Vitamin B5) -- 500mg/day (adrenal support)
- Ashwagandha -- 300-600mg/day (adaptogen; reduces cortisol which may preserve adrenal DHEA output)
- Pregnenolone -- 25-50mg/day (upstream precursor to DHEA; can support both cortisol and DHEA pathways)
Lifestyle:
- Manage chronic stress (elevated cortisol "steals" pregnenolone from the DHEA pathway -- pregnenolone steal)
- Adequate sleep (7-9h) -- adrenal recovery depends on sleep quality
- Avoid overtraining -- excessive training volume with inadequate recovery depletes adrenal reserves
When HIGH (>15.2 umol/L):
- Uncommon unless supplementing DHEA exogenously
- Can indicate: adrenal hyperplasia (congenital or late-onset), adrenal tumour (rare), PCOS-related (not applicable in males)
- High DHEA-S can increase conversion to estradiol and DHT -- may worsen androgenic side effects (acne, hair loss)
- If elevated without supplementation: investigate adrenal function (17-hydroxyprogesterone, cortisol, ACTH)
- Reduce or stop DHEA supplementation if levels are above range
Clinical context:
- DHEA-S is primarily adrenal, not gonadal -- it is NOT directly suppressed by AAS/TRT (unlike LH/FSH/testosterone)
- However, chronic AAS use with elevated cortisol (common with trenbolone, heavy training) can indirectly lower DHEA-S over time
- Useful marker for overall adrenal health and stress status in athletes
