| Time to effects | Effects are usually visible from the first night of use — shortened time to fall asleep was observed in studies after a single 3 g dose before bed. | Disruptions to the GH pulse and cortisol rhythm appear after just a few nights of shortened or fragmented sleep; improvement after restoring regular, sufficient sleep is usually visible within several days to about two weeks. |
| Who it's for | People with subjectively unsatisfying sleep quality or a feeling of not being rested despite apparently adequate hours of sleep | People doing strength or endurance training, for whom GH-dependent tissue recovery has practical relevance |
