What is Somatropin?
Somatropin is the standard recombinant form of human growth hormone used in clinical and research settings. It binds the GH receptor to stimulate IGF-1 production and promote growth and anabolic signaling.
Key Benefits & Mechanisms
linear growth support
lean mass preservation
bone mineral accrual
IGF-1 elevation
Research Summary
Somatropin is the best-studied growth hormone peptide, with decades of clinical use in pediatric and adult GH deficiency. Trials consistently show increases in IGF-1 and growth velocity, with adverse effects mainly reflecting excessive GH exposure.
Related Peptides
Ibutamoren
Ibutamoren mesylate (MK-677)
Ibutamoren is an orally active ghrelin receptor agonist that increases pulsatile growth hormone and IGF-1 secretion. It has been studied for effects on lean mass, recovery, and age-related anabolic support.
Growth HormoneAnamorelin
Anamorelin hydrochloride (ONO-7643)
Anamorelin is a selective ghrelin receptor agonist developed to stimulate appetite and growth hormone signaling. It has been investigated primarily in cancer cachexia and other wasting states.
Growth HormoneMacimorelin
Macimorelin acetate (AEZS-130)
Macimorelin is an orally active ghrelin mimetic used as a growth hormone stimulation agent. It produces a rapid GH rise after a single dose and is used clinically to help diagnose adult GH deficiency.
Growth HormoneCapromorelin
Capromorelin hydrochloride
Capromorelin is a ghrelin receptor agonist that stimulates growth hormone release and increases appetite. It is best known in veterinary medicine, but it has also been explored in human research settings.
