and since we are talking about a product that has no such studies, is the risk of it causing that worth the limited effect? Sure there are blood tests at x days in showing a higher total testosterone, are there any studies showing DAA causes an increase in strength or lean muscle mass? no.
Its one thing to separately dismiss side effects in a product where there isn't any particular MOA of the product that is reasonable to cause them but its worth considering when there is an MOA for it to cause them.
This doesn't mean I think people shouldn't use DAA, but they should be aware that this is a possible issue, and decide for themselves. if they already have anxiety issues to a lesser or greater extent, they might be better off using something else.
