Ok everyone debates or says OSTA can or cannot cause shutdown, from everything read, which was a lot cause I research the death out of something before I use it, was that everyone reacted different
Some users experienced no shutdown, some a little, some a lot
However, I have yet to see someone not fully recover
For me, pretty sure 0 shutdown, or at least full recovery, I've run it twice, 4 weeks and 8 weeks, had bloodwork done each time and my test levels were in my normal range shortly after cycle
Never had bloods done while on though, so those results could be different
