What it is
A PDE5 inhibitor, the active drug in Cialis. Peak sells it as Peakdalafil.
How it helps
Stronger, more reliable erections. It lasts up to a day and a half, so timing matters less than with Viagra.
What to watch for
Prescription drug. Never with nitrates or poppers: the drop in blood pressure can be dangerous. Headache, flushing and back ache are common.
