How Long Does 7-OH Last?

When exploring kratom extracts and alkaloids, one of the most common questions people ask is: how long does 7-hydroxymitragynine (7-OH) last? 7-OH is the most potent alkaloid found in kratom and is often isolated into products like tablets, vapes, and shots. Since it binds strongly to opioid receptors, its effects can feel more intense and last longer than plain kratom leaf.
