Quick Rules

  • Subcutaneous administration only.
  • Mix 10 mg vial with 2 mL (200 units) BAC water.
  • Initial dose: 10 units (500 mcg) to test tolerance.
  • Standard dose: 40 units (2 mg).
  • Maximum dose: 50 units (2.5 mg) only if tolerated.
  • Inject 45–60 minutes before sexual activity.
  • Do not exceed 1 injection in 24 hours.
  • Do not exceed 8 standard doses (16 mg total) per month.
  • Rotate injection sites for comfort and hygiene.
  • Long-term use may desensitize the melanocortin system.
  • If more frequent use is needed, rotate with alternate peptides.
  • Dizziness and blurred vision together may indicate a serious issue — seek medical attention immediately.

Do NOT use if

Uncontrolled cardiovascular disease · severe hypertension · history of severe allergic reactions to melanocortin agonists · pregnant or breastfeeding · uncontrolled mood disorders. Always test tolerance with the initial dose before using a standard therapeutic dose.
