go w/ a T3/T4 combo say around 25mcg/100mcg respectively, for your last 4 weeks.. just make sure your off of them before you start pct.
if your running long esters .. no need to start pct protocol after last stick.. thats absolutly pointless.. you need to wait the proper time so that when u do administer your SERM and AI that your exogenous adrogen levels are low enough not to prevent recovery.
