If you don't get PCT right you will lose all gains or possibly end up smaller since your own test production will have shutdown in the cycle and you have to get it going again.... is this a good course to start on?
Not really - for one you need to see how you react to one compound (ie. test) and deca may well make your libido go down.... do your really want this at 22??
how much should i be training?
Train on cycle as you train off cycle - exactly the same
