Looking around a little bit, it's not limited to Ibuprofen. It seems to be all NSAIDs, but also not limited to NSAIDs. This includes Claritin, Zyrtek and most if not all other antihistamines.
In addition SSIRs (antidepressants) have an antagonistic effect on testosterone as well as Spironolactone, and corticosteroids (Asthma inhalers).
I thought maybe acetaminophen would be safe since it's not a NSAID but it also has a negative effect on testosterone.
I looked up opioids, yep... they lower testosterone too.
So basically, don't take pain killers or at least limit their use as much as possible.
Too many ibuprofen after doing the decathlon back in 1978! I am kind of kidding - and kind of serious here. I feel that there may be something to this - and it is possible that there is some form of collusion. When crazy stuff goes down that curtails populations (reproductive issues), including plasticizers in water bottles, etc., BE SUSPICIOUS. It is a NWO agenda item to radically reduce populations and to do so with no major resistances. Fluouride in is just one of the pieces of that tangled puzzle.
