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
DEXA body-fat % is gold-standard relative to BIA / circumference methods. Range above is generic — actual optimal varies meaningfully by age and sex (30y M: ~10-15%, 30y F: ~18-23%, older adults: higher). GLP-1 agonists (tirzepatide, semaglutide, retatrutide), 5-amino-1MQ, AOD-9604 — all documented to lower body fat in trials. GH-axis peptides have mixed evidence.

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.
