The issues that these questions cover, would you call them detrimental to my health?
Don't bother answering that, I'd like to keep the thread on topic.
I will answer anyway.
Mainly just an old man trying to get a boy to consider the benefits of forethought.
We do not encourage the use of steroids here at AM but understand that they are going to be used regardless so intelligent, well planned use is to be preferred over the ignorant variety. Yes, you are ignorant. That is not an insult, it just referencing a lack of knowledge which you acknowledged by asking elementary questions and in no way reflects actual intelligence.
Whether or not these issues relate to health is mute. A wise man will gather all necessary information before launching an endevour as to ensure that all necessary requirements are met beforehand thus reducing the chances of failing to accomplish intended goal. Was a successfull post cycle therapy part of the original goal and thus included in planning?
You asked some very basic questions that could and should have easily been answered long before you swallowed the first dose of your steroid cycle. That and your only 21. Your hormone levels should be at a level that will be unriveled at any future point in your life. Stupid is as stupid does. Wisdom is the ability to make right choices. Intelligence lacking wisdom is foolishness.
