T-score, lumbar spine (L1-L4)

Measured in SD

Reference ranges

Optimal
-15 SD
functional-medicine target
Standard
-2.55 SD
lab reference range

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

Tesamorelin and GH-axis peptides (CJC-1295, ipamorelin, sermorelin, MK-677) have documented bone-density-favorable effects via IGF-1 elevation, though direct DEXA-confirmed BMD trials are limited. NAD+ precursors (NMN, NR) — no direct BMD evidence; mitochondrial-health framing is speculative for skeletal effects.

Have a recent T-score, lumbar spine (L1-L4) 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.
