Best Initio Side Effect Dupes

Best overall dupe: French Avenue After Effect — ~86% match, 5-7 hour longevity, $34. Described by testers as the closest overall match to Side Effect's addictive rum-tobacco-vanilla-cinnamon combination, close enough that some wearers call it a tie with the original by the dry-down.

Initio's Side Effect is one of the most-cloned niche releases of the last few years, and unusually for a $320+ niche fragrance, its dupe market is well-documented and genuinely competitive.

Ranked comparison

Top picks explained

1. French Avenue After Effect

Loses a bit in the first hour with more alcoholic bite than the original, but by hour four the rum-tobacco-vanilla dry-down is close enough that testers have called it a tie — or even preferred it for being sweeter and more approachable.

2. Alexandria Upside Down

A more premium re-engineering at Extrait de Parfum concentration, with reported 10-12+ hour wear on skin and even longer on clothes. Pricier than After Effect, but built for maximum performance.
