| Side effects | Nausea and facial flushing · Darkening of existing moles and freckles · Spontaneous erections · Melanoma risk concerns |
| Half-life | About 33 hours |
| Administration | Subcutaneous injection |
| Dosing overview | Loading 250–500 mcg daily, then weekly maintenance |
| Storage | Refrigerated after reconstitution |
| Legal status | Not approved anywhere; illegal to sell for human use in the UK, EU and US. |
