- 0.5–1.5mg per dose, 2–3x/week
- Libido enhancement, central arousal, spontaneous erection
- 60–90 minutes
- 6–8 hours
- Mild flushing, stretching/yawning at higher end of range
- Therapeutic window for sexual function research. Minimal tanning at this dose range
- 1.5–3mg daily for 7–14 days
- Pigmentation (tanning), melanogenesis in melanocytes
- Cumulative (3–5 days)
- Persistent (weeks after cessation)
- Nausea (50–70% incidence), darkening of moles, facial flushing
- Doses required for tanning consistently produce GI side effects that interfere with libido studies
- >3mg per dose
- Severe adverse events
- Immediate
- Variable
- Vomiting, prolonged erections (>2 hours), hypotension, melanocytic activation
- Not recommended. Side effect profile exceeds any research benefit
