All items were ran for 3 days.
CIA started off at 15mg for one day then down to 5 for 2
T3 started at 100mcg and is now at 50mcg for 2 days
B12 is still at the 1000mcg from day 1
T3 does look to increase blood pressure
Everyone loves rat studies right!?

I'm probably wrong like I usually am, someone may want to clarify.
One option is to stop all of them and reintroduce them one by one and wait a few days or a week before introducing the next. When you get the sides you'll know which compound is doing it or which combination of compounds. Another option is maybe you're hypersensitive to PDE5 inhibitors so maybe try 5mg EOD than bump it up to 10mg EOD or 5mg ED. Work your way up until you hit the desired dosage or sides show.
B12 injections or sublingual? I would have to double check but i think B12 can cause certain things that you described. Also the study you posted uses doses of .2mg/kg BW. We are using much much smaller doses.
