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
Pituitary gonadotropin. In men, LH stimulates Leydig cell testosterone production. In women, LH triggers ovulation. Pulsatile secretion — single draw is a snapshot. Exogenous androgens (TRT, AAS) suppress LH — low LH + low T = primary hypogonadism vs central; LH paired with T distinguishes the two. Kisspeptin (a peptide) directly stimulates GnRH → LH. Gonadorelin (a peptide) and hCG (NOT a peptide, often co-used) mimic LH signaling to maintain testicular volume during TRT. CJC-1295 + Ipamorelin: minimal LH effect. RANGES FOR ADULT MEN; women have cycle-dependent values with mid-cycle peak 25-80.

Have a recent LH (luteinizing hormone) 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.
