HGH vs HGH Fragment 176-191
HGH and HGH Fragment 176-191 are compared here on the things that actually differ between them: what class each belongs to, what each acts on, how each is supplied and what each costs per milligram. Where the registry has no figure for one of them the row is left out rather than filled in.
Side by side
| HGH | HGH Fragment 176-191 | |
|---|---|---|
| Class | Recombinant human growth hormone (191 amino acids) | C-terminal fragment of human growth hormone |
| 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 fragment of the C-terminus of hGH, studied for lipolytic activity in adipose models without the full growth-promoting or glucose-affecting profile of intact growth hormone. |
| 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. |
| Half-life | Short in circulation, typically two to three hours; downstream IGF-1 elevation persists considerably longer. | Short. |
| 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, protected from light. |

What actually differs
The clearest difference is class: HGH is a recombinant human growth hormone (191 amino acids), HGH Fragment 176-191 is a C-terminal fragment of human growth hormone. 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, HGH Fragment 176-191 as a lyophilised powder or pre-filled pen. Half-life differs as well: Short in circulation, typically two to three hours; downstream IGF-1 elevation persists considerably longer for HGH against Short for HGH Fragment 176-191.
