Why not figure out what you are trying to do first of all. You go to your doctor and he gives you the dime store treatment by telling you to go on TRT because of a single low test reading and no other bloodwork. That is absolutely terrible and any doctor that tells you to go start this with mid 500 levels and no other testing is just plain out of their element. There are many factors that could be causing low energy, lower libido, etc.. and TRT is where you end up, not where you start. So, if you say that you don't plan to do this for life, but seem to want to be fixed (because it bothered you enough to go to the doc), figure out what you are really after. Do you want to find out and fix what is bothering you or do you want to run a quick cycle? You BB friend is doing you no favors by telling you about pros like that and leaving out that most people have e2 issues that need to be addressed at levels that 200-250 will bring and then what? You going to just stop and then run a PCT only to be back where you were?
This site is a wealth of information, but also has some really ignorant people on it that are willing to just tell you what you want to hear and how much to take of something. If you want to go for it, then do it. Just realize that you are only running a tiny cycle and not addressing anything.
