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
Z-score compares against age-matched peers — different intervention threshold than T-score. Z-score < -2.0 in adults under 50 prompts secondary-cause workup. No specific peptide literature; same GH-axis context applies.
Have a recent Z-score, lumbar spine (L1-L4) 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.
