If you are taking Test Enanthate, you wait till 3 wks after last injection
If you are taking orals, such as d-bols or winny, you start hours after last pill.
Question is what about other AAS. Are all single esters like Enan, Prop, Sust, all 3 wks?
What about Tren?
Inj. Winny?
Deca?
This is hypothetical, assuming you weren't running test.
