It obviously sounds like you're kinda new to the world of AAS. I don't know how old you are, but at 6.2ft I assure you that your genetic potential is not 165 lbs. At that height, you are nowhere near ready for gear. You still have years of natural potential that you haven't even begun to tap into. I'm not saying this to be a dick, I'm just trying to look out for you. If you can't get past 165 naturally then something is wrong with either your nutrition or your training routine, or quite possibly both. These two things are crucial in the world of bodybuilding and aesthetics. If you do not have these two things nailed down, then running a cycle is pointless. You won't be making anywhere near the kind of gains you could make with a good diet and solid routine.
My best advice for you at this point is to visit the diet and training section and have people look at your routine and or diet. Furthermore, I don't think you really know what a cycle of gear involves, and I highly encourage you to read all of the stickeys for newbies on this forum and use the search feature to find any information on topics you're curious about.
Remember there are no shortcuts in life, and steroids are no exception. There's a lot more involved then just injecting yourself or popping a few orals. If you are not careful you can cause severe harm to your health and shut down your natural testosterone production. Also be sure to read about PCT (post cycle therapy).
