Is it safe to still use if it expired in the last 2 mo, or is it just effecting it’s efficacy?

Oxy-Powder typically has a two-year shelf-life from the purchase date. It's best to use Oxy-Powder by this time to ensure maximum results. At your discretion, you can still consider using Oxy-Powder beyond the Best By Date.
