woah woah woah - in about 20 minutes you are going to get reamed by other members so let me get in a word first.
1. PCT = Post cycle therapy. When you take any anabolic, prohormone (PH), or designer steroid (DS) your body shuts down its own testosterone production and therefore you need to line up a series of medication to take to reboot your system.
2. You should not be asking for help setting up a cycle you are almost done taking. You should diligently research a cycle, then start. And you must set up and acquire PCT before starting.
3. You should NOT do back-to-back cycles. If you are finishing a cycle now you need to take time off equal to time on before starting your next cycle. Time on = time of cycle + time on PCT.
4. If you don't know what PCT means you probably aren't taking the right cycle support supplements. You need a whole bunch of stuff and I can't go into it all here.
5. At 6'3" and 165 lbs. you probably have alot of room to grow naturally. You could probably get the results you are looking for with a change in diet. How old are you?
