Is IGF-1 LR3 stronger than HGH?

They do different jobs in the growth axis, so stronger doesn’t really apply. Growth hormone (HGH) binds its own receptor and signals the liver to make IGF-1, and it also has direct effects, such as on fat breakdown. IGF-1 LR3 skips that step and acts directly on the IGF-1 receptor, without growth hormone’s other actions.

What researchers can say is that IGF-1 LR3 is more potent than native IGF-1 in many cell assays, because it escapes IGF binding proteins. Comparing it with upstream peptides such as Sermorelin 10mg or Ipamorelin helps separate growth hormone effects from IGF-1 effects. Growth hormone is approved for specific deficiencies, but IGF-1 LR3 and these research peptides aren’t. Shop IGF 1 LR3 for growth axis research.
