| Time to effects | Works quickly — a shorter time to fall asleep is often noticeable on the very first night of use, typically 30–60 minutes after taking it. | 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 jet lag or working shift schedules | People doing strength or endurance training, for whom GH-dependent tissue recovery has practical relevance |
