I ordered some cia from AR to give it a go, maily for BP upkeep, but really not need the extra blood flow to the penis. It's only been a couple days, but have already noticed it's much harder to get off! lol, also orgasms are a little more intense due to the nature of concentration needed to get off, I usually end with a long scream lol, NO change in BP yet, so I will give it a week and if my BP 135/82 does not drop I think I will discontinue use of this reasearcg chemical lol.
