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
