COMPARISON: TESAMORELIN vs HGH
Tesamorelin vs HGH: What's the Difference?
Stimulating your own hormone vs replacing it
Tesamorelin vs HGH (human growth hormone) is a common question, and the difference is mechanistic: one stimulates your body's own hormone, the other supplies the hormone directly.
At a Glance
| Tesamorelin | HGH (somatropin) | |
|---|---|---|
| What it is | GHRH analog (secretagogue) | Recombinant growth hormone |
| Mechanism | Prompts your own GH release | Replaces GH directly |
| Approved use | HIV-associated lipodystrophy | Specific GH-deficiency conditions |
| Monitoring | IGF-1, glucose | IGF-1, glucose, others |
| Category | Prescription (specific use) | Prescription (specific uses) |
Stimulate vs Replace
Tesamorelin is a GHRH analog — a secretagogue that prompts the pituitary to release the body's own growth hormone. HGH (somatropin) is growth hormone itself, given directly. This is the central difference.
