I didnt know i could affect my endocrine system and permanently shut down my natural test until after i got off my first cycle ( which is my fault i shoulda studied up on it alot more) But i was wondering if anyone already think i shut down my natural test and disrupted my endocrine system from my first cycle of 500mg of test e a week for 10 week (actually ended up being 9) i did my pct with chlomid correctly. just curious if i f***ed up already. Is it a gaurentee my natural test didnt start back up and that it stoppped my endocrine system from further developing? i am 20 almost 21. thanks for the help!!
