Safety at a glance

Full safety details

Most-reported side effects

  • Mild injection-site reaction
  • Rarely headache

Don't use if…

  • Pregnancy

What it is

Modified C-terminal fragment of human growth hormone designed to retain GH's lipolytic action without raising IGF-1 or affecting blood sugar.

Mechanism of action

Activates beta-3 adrenergic receptor signaling in adipocytes, stimulating lipolysis and reducing lipogenesis. Does not bind GH receptor classically.

Reported benefits

  • Targeted fat loss—particularly stubborn / visceral fat
  • No IGF-1 elevation; no growth-related side effects
  • Often added to GLP-1 or GH stacks for adipose-specific support

Evidence notes

Met-X obesity trial (Phase IIb): modest fat loss but did not hit primary endpoint. Safe profile across human studies.
