A couple of years ago while using tren I went to the doc for a check up . He checked my bp and it was 160/100.my blood pressure is always high normal even with the 2 monsters I drink a day .so I would have to say tren definitely raises bp more than caffeine
For 7 years of Tren use (intermittent) my BP was fine. Then something happened to me and I had to lower the dose to keep my blood pressure in normal ranges. I did cardio every other day and ate clean and took all kinds of supps but that didn't help. I guess it's age dependant.
For me the tren didn't but other said it did. At times I felt like I would get more if a flush similar to niacin but my niacin was low that day so I factored it to be tren, with the BP
