I've heard you can negatively impact lipid values from too much cardio in addition to the bp issues. Hdrol is generally the go to compound for first timers because the cycle is shorter and less intense. You have a better shot at keeping the gains and the sides are less intense to the extent that they occur at all.
Im thinking of ultradrol for my second cycle. 4wks at 12mg a day. I've been able to assess my tolerance to some degree from running pmag as a first cycle, so I know a little of what to expect. I also had the experience if learning from beginner mistakes, which might help me get more from a compound that has more to give.
