hey bro
my opinion is yes to different recovery times for different AS some things stay in your system longer (deca) and ya have to take that into account....also somethings just shut people down HARD (fina/deca) but again everyone is different as you will tell if you keep reading....bro my suggestion to you is read EVERYTHING you can and take what is said here with a grain of salt because we are all going to react differently....if and when you do decide you are ready to give AS a go just use one thing whether it be test,dec,eq, or winny (my first) because doing it this way will let you know how you react to that certain item instead of guessing.....say you do deca and test and you start to grow boobs you wont know if its through progesterone or estrogen....read read and read somemore...good luck....peace
