When to stop

  • Numbness, tingling or pain in the hands or wrists that persists. This can indicate fluid-related nerve compression.
  • Noticeable swelling in the hands, feet or face.
  • Symptoms suggesting raised blood sugar: unusual thirst, frequent urination, or blurred vision. Growth hormone opposes insulin.
  • Any new lump or growth. Growth hormone and IGF-1 promote cell proliferation, so this warrants prompt investigation rather than watching.
  • Signs of infection at an injection site, or any allergic response. Seek urgent care for the latter.

Not approved for human use in the United States for any indication. The FDA has identified ipamorelin as a substance raising concerns for use in compounded preparations. Material sold online is a research chemical.
