HGH vs Ipamorelin

Side by side
| HGH | Ipamorelin | |
|---|---|---|
| Class | Recombinant human growth hormone (191 amino acids) | Growth hormone secretagogue (GHRP) |
| Acts on | A recombinant form of the 191-amino-acid pituitary hormone. Acts directly at the GH receptor and indirectly through hepatic IGF-1 production. | A pentapeptide ghrelin-receptor agonist studied for selective growth hormone release with minimal effect on cortisol or prolactin, which distinguishes it from earlier GHRPs. |
| Supplied as | Lyophilised powder supplied in international units (iu), commonly as 10iu vials in 100iu kits, or as a pre-filled pen. | Lyophilised powder or pre-filled pen. Also supplied blended with CJC-1295. |
| Half-life | Short in circulation, typically two to three hours; downstream IGF-1 elevation persists considerably longer. | About two hours. |
| Storage | Refrigerated at 2-8 C both before and after reconstitution. Never frozen. Growth hormone is a folded protein and loses activity if frozen or shaken vigorously. | 2-8 C. Reconstituted: refrigerated. |

What actually differs
The clearest difference is class: HGH is a recombinant human growth hormone (191 amino acids), Ipamorelin is a growth hormone secretagogue (GHRP). They are not supplied the same way. HGH comes as a lyophilised powder supplied in international units (iu), commonly as 10iu vials in 100iu kits, or as a pre-filled pen, Ipamorelin as a lyophilised powder or pre-filled pen. Also supplied blended with CJC-1295. Half-life differs as well: Short in circulation, typically two to three hours; downstream IGF-1 elevation persists considerably longer for HGH against About two hours for Ipamorelin.
