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
Percentage of blood volume occupied by red blood cells; tightly correlated with hemoglobin (HCT ≈ HGB × 3). Same peptide interactions as hemoglobin — TRT and AAS reliably raise HCT; values >52% in men or >48% in women often trigger therapeutic phlebotomy on TRT to reduce stroke risk. CJC-1295 / Ipamorelin: minimal effect. KEY CAVEAT: dehydration acutely raises HCT 2-5% — interpret in context of hydration status. Smoking chronically raises HCT (hypoxic stimulus). RANGES SHOWN ARE FOR ADULT MEN; women typically 34.9-44.5%.
Have a recent Hematocrit (HCT) 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.
