- Dorr et al. 1996
- 10 days
- 10
- Melanogenesis, erections
- None
- No chronic dosing pattern
- Wessells et al. 2000
- 20
- Tanning, erectile function, BP
- Acute only (2hr post-dose)
- No sustained BP tracking
- University of Arizona 2006
- 60 days
- Eumelanin, MED
- Longest published trial. Still under 9 weeks
- Netherlands Case Series 2019
- 6–18 months
- 14
- Dermatoscopic changes in nevi
- Observational only
- Retrospective. No baseline measurements
- The table makes the problem clear: even the longest controlled trial (60 days) wouldn't capture the effects most relevant to typical use patterns, and the only data approaching real-world use comes from uncontrolled case reports.
