Looking at your past threads, it would appear that most of your cycles have thus far been completely oral with no test base. Mainly composed of some of those flaky designer steroids, no less. You're in different territory now, the assumption that you won't need an AI is ridiculous, especially given the fact that you have people in this thread who have taken what you're about to take and have advised you to take medication to help control estrogen. Their examples may be anecdotal, but it is more than medically proven that testosterone will aromatize in your body. Your estrogen levels WILL increase, and if it's too much, you'll thank the heavens that you have a safety net in the form of an aromatase inhibitor. Gynecomastia is a hell of a lot easier to get than it is to get rid of.
Secondly, I hate to be the party-pooper, but are you on any other medications? You have a previous thread which talks about being on a pretty potent antipsychotic, are you still taking medication for the sake of bipolar behavior and/or sleeping issues? It's an important part of the process to really analyze how an anabolic steroid will interact with your current medication. I'm not a believer in the "roid rage" mythology, but if you already suffer from a bipolar disorder, I certainly do believe that heightened (or lowered) hormone levels could have a significant effect on your mood swings.
I realize a large part of this forum seems to be relatively self-destructive when it comes to just taking steroids and saying **** tomorrow, live for today, but you really do have a lot to consider when doing this. I'm not trying to be the pot calling the kettle black here, trust me...I take AAS as well. But every user has a different set of issues to overcome, and I just want to make sure you're assessing yours correctly. This is your first "real" cycle...you should be extremely concerned about how you handle it. It could easily dictate habits in your steroid use for years to come. One too many people I've heard saying "I ate like **** on my last cycle and I was fine (ie 'I didn't die'), so I'll do that for this cycle too." Too much assumption and not enough bloodwork on these forums.
To weigh in on supports...one of the big downfalls of the "Cycle Assist" product is that a lot of people seem to take it and assume their bases are covered. I really think your money could be better spent other places, often times there are many natural resources for health on-cycle. Just as general suggestions, I enjoy Hawthorn Berry for blood pressure management, cranberry for kidney health (although there are significant examples of cranberry being beneficial to our liver as well), s-AME for liver function, and then finally as a general health promoter, a multivitamin and fish oil.
Just to establish it - I am not opposed to the use of anabolic/androgenic steroids. I am, however, opposed to irresponsible or uninformed decisions in use. Just making sure you've really analyzed your situation and are 100% on the safety of taking the substances you mention. On top of that, I want to make sure you have all your ducks in a row to maintain health as best you can while on-cycle. Best of luck to you
