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
Anaerobic metabolism end-product; widely considered the most accessible proxy for mitochondrial efficiency. Elevated resting lactate suggests inadequate oxidative phosphorylation (mitochondrial dysfunction, severe illness, sepsis); low optimal range suggests efficient mitochondrial function. Post-exercise lactate clearance rate is more informative than resting value alone — slow clearance = poor mitochondrial capacity. Mitochondrial peptides like SS-31 (elamipretine) and MOTS-c are theorized to improve lactate handling but human data is limited. CJC-1295 / Ipamorelin / Tesamorelin: GH-axis activation modestly improves mitochondrial biogenesis over months; effect on resting lactate is small. KEY CAVEAT: must be drawn at rest (sit 15+ min before draw); recent exercise, anxiety, or breath-holding during venipuncture elevate lactate transiently 2-4x. Tourniquet time matters: prolonged tourniquet > 1 min falsely elevates.
