- Onset Timeline
- 3–5 days (initial), 2–3 weeks (peak)
- 7–10 days (first visible darkening)
- Appetite effect precedes visible tanning by several days
- Dose Threshold
- 0.5mg daily produces noticeable effect
- 0.25–0.5mg sufficient for tanning
- Appetite suppression requires higher or more consistent dosing
- Mechanism Pathway
- MC4R activation in hypothalamus → leptin-like satiety signal
- MC1R activation in melanocytes → melanin synthesis
- MC4R binding affinity is higher than MC1R. Appetite effect is stronger pharmacologically
- Duration Per Dose
- 12–18 hours (receptor occupancy)
- Melanin persists weeks after stopping
- Appetite effect reverses within 24–48 hours of cessation
- Tolerance Development
- Partial tolerance after 3–4 weeks continuous use
- Minimal tolerance. Tanning deepens with continued use
- MC4R may downregulate; MC1R does not
- Adverse Event Rate
- Nausea in 25–40% at doses >1mg
- Flushing, mild nausea in 15–20%
- GI side effects track with appetite suppression intensity
