Analysis of growth hormone releasing hormone and its analogs in urine using nano liquid chromatography coupled with quadrupole/orbitrap mass spectrometry.

Scientists created a super‑sensitive urine test that can spot growth‑hormone‑releasing peptides like sermorelin at very low levels (0.5 ng/mL). The method uses tiny‑scale liquid chromatography and high‑resolution mass spectrometry, and it meets anti‑doping lab standards.
