What is Somapacitan?
Somapacitan is a long-acting growth hormone analog designed for once-weekly dosing. It retains GH receptor activity while extending exposure through reversible albumin binding.
Key Benefits & Mechanisms
once-weekly dosing
sustained IGF-1 elevation
adherence improvement
gh-deficiency replacement
Research Summary
Somapacitan has been studied as a once-weekly alternative to daily GH therapy in both adults and children with GH deficiency. Trials show durable IGF-1 control and noninferior growth outcomes relative to daily comparators in selected populations.

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.
