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
In women, progesterone is produced by the corpus luteum after ovulation — a mid-luteal value (~7 days before expected period) >5 ng/mL confirms ovulation occurred; >10 ng/mL is optimal. Postmenopausal women run <0.5 ng/mL. In men, progesterone is normally <1 ng/mL — elevation can indicate exogenous progestational AAS, certain testicular tumors, or extreme stress (cortisol pathway crossover). RANGES SHOWN ARE FOR REPRODUCTIVE-AGE WOMEN; men should be <1. Timing critical — draw 7 days before expected next period for ovulation confirmation. No direct peptide effects in common stacks.
