Our Final Verdict

7

Lean PM

3.5

Lean PM is a clean, straightforward nighttime fat burner — melatonin for sleep initiation, L-Theanine for relaxation, and green tea extract for thermogenic support while you sleep. It's an honest product with transparent dosing. The limitation is the green tea dose — without the cortisol-suppressive compounds that help high-stress individuals achieve the restorative deep sleep where HGH and fat oxidation peak. SleepLean addresses the cortisol and deep sleep architecture problem that Lean PM doesn't touch.
