Reference ranges
Optimal ranges are tighter than standard lab ranges and reflect functional-medicine targets, not the populations they were derived from. Reference bands depend on sex, age, and circumstance — Juno's lab analysis layers your profile context onto the printed range when you paste a value.
Peptide relevance
Adrenal androgen precursor; stable surrogate for DHEA production (sulfated form has longer half-life). Strongly age-dependent — declines by ~10%/decade after age 25, so older users will read lower regardless of any intervention. No direct peptide effects documented for the common stack peptides (BPC-157, TB-500, CJC/Ipamorelin, Tesamorelin, GLP-1s). DHEA supplementation (not a peptide) raises both DHEA and downstream androgens including testosterone — often used alongside peptide stacks but tracked separately. RANGES SHOWN ARE BROAD ADULT MALE; reference labs band by age (men 30-49 ~280-640, men 70+ ~40-325) and sex (women ~150-410 at 30, ~20-200 at 70+).
Have a recent DHEA-S (dehydroepiandrosterone sulfate) value?
Paste it on the lab analysis page. Juno reads your active stack + (if shared) your medications and conditions, and surfaces plausible contributors with citations. Doesn't diagnose.
