That is why IMHO on cycle support and post cycle therapy (pct) are the most critical aspects to any AAS cycle...on cycle to minimize testicular shutdown and protect your extremities (heart, liver, kidneys, BP, and immune system)...
post cycle therapy (pct) is dictated by cycle support and AAS (harshness of cycle)...your post cycle therapy (pct) will be much more effective if you take the necessary precautions to minimize shutdown and keep the boys alert during cycle instead of having them shutdown completely and having to revive them...make sense? This is where HCG and/or HCGenerate come to play, liver support supplements...or basically my cycle support supplement N2 Guard.
It is like this...when we have a water main break at my work, if we shut down the main to work on it and shut it down 100%, it causes a vacuum where dirt and contaminates can enter the water main which creates a list of things we have to do in order to put it back in service for the residents to have safe potable water (flushing of the main for hours, bacterial sampling, flushing individual water services before the water meters, pain in the you know what!). Where if we just throttle the main down and let it still be active and perform the repair without shutting it down 100%...then all the other things are not needed and we have brought the main back to normal operating condition more effectively...make sense?
Minimize testicular shutdown and not have them shutdown 100%, the post cycle therapy (pct) has a better effect of bringing hormone levels back up to normal operating condition without drastic measures and feeling like a piece of sh*t! Depression is one.
Also consider bridging in between cycles too to keep gains coming and keep your mind focused at continuing to build muscle and feel great! SARMs is a great way to go, as well as a supplement I use personally which is Bridge.
This is just my opinion and what I like to follow, but feel strongly about..."on cycle support and post cycle therapy (pct) are the most important components to all AAS cycles...period!!!"
