When to start PCT after Sust?

Can anyone tell me how long after last Sust shot should PCT be started?

-Thanks

3 weeks from your last sust shot.

Below you'll find starting times for your PCT based on the active life of each compound. The active life is the duration of time it takes for the exogenous hormone to be absorbed, utilized, and expelled; no longer being bioavailable. Keep in mind that active life is an approximation which is dependant on dose, ester, as well as the individuals metabolization of the compound ; but for the moderate user, these are as close to precise as you'll find.

Anadrol/Anapolan: 24 hours after last administration
Deca: 21 days after last injection
Dianabol: 24 hours after last administration
Equipoise: 21 days after last injection
Fina: 3 days after last injection
Primobolan depot: 14 days after last injection
Sustanon: 18 days after last injection
Testosterone Cypionate: 18 days after last injection
Testosterone Enanthate: 14 days after last injection
Testosterone Propionate: 3 days after last injection
Testosterone Suspension: 24 hours after last administration
Winstrol: 24 hours after last administration
