Calculators
Like clomiphene, tamoxifen is used in PCT, but it works through a slightly different mechanism and has a different tolerability profile.
An oral PCT medication with a half-life around a week for the parent compound, while its active metabolite lingers even longer.

Is tamoxifen more effective than Clomid for PCT?
There’s no clear-cut answer — both are used in PCT, and the choice usually comes down to tolerability and prior experience rather than one being flatly "stronger."
Why does tamoxifen last so long in the body?
Beyond the parent compound, an active metabolite forms with a longer half-life, so the effect lingers longer than the parent drug's own half-life would suggest.
