Hexarelin vs Ipamorelin
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| Hexarelin | Ipamorelin | |
|---|---|---|
| Evidence | Preliminary human | Preliminary human |
| Class | GH secretagogue | GH secretagogue |
| Summary | A synthetic ghrelin-mimicking peptide that reliably spikes growth hormone in small studies, but was never approved and is banned in sport. | A selective growth-hormone-releasing peptide with early human safety data but a failed efficacy trial; never approved and banned in sport. |

Hexarelin
Hexarelin is a synthetic peptide that mimics the hunger hormone ghrelin to provoke a sharp, short-lived burst of growth hormone (GH). Small human studies in the 1990s showed it does this reliably, but every trial was tiny, brief, and measured surrogate markers rather than real-world outcomes. It…
Ipamorelin
Ipamorelin is a synthetic peptide that briefly raises growth hormone (GH) levels. It has been tested in humans, but the one trial that measured a real clinical outcome did not work, and it has never been approved for any use.
