This is a way loaded question.
First, before I give my extremely uninformed opinion, I am in my 20’s, not overweight, regularly take 1.3 and find no deviation in blood pressure measurings when I’m consistently taking it or not.
That being said, I think it’s probably in your best interest to make an honest assessment if you believe the juice to be worth the squeeze. As much as I’d like to assert 1.3 is perfectly fine and safe, it has recently been banned for a reason (all other merits of the FDA are side-barred here,) because it has not been proven safe -or- anything otherwise in a long-term study. So - if you are noticing negative health effects from taking the substance, only you can ultimately decide if it’s worth it.
Does 130/90 sound like a radical number worth being concerned over? I wouldn’t think so. Do I have the same body as you? Certainly not. I’m also not a medical professional.
That being said, there are many compounds much more beneficial to a physique and its progress (I’m guessing you can surmise what I’m referring to) that also have health risks associated with them. Again - Is the juice worth the squeeze? There are plenty of pre-workout supplements without 1.3 these days that many enjoy.
The time of working out vs when you take your blood pressure have so many X factors. Is it mild White Coat Hypertension? How could your food choices be affecting this number? Stress? So on and so forth.
And lastly, yes, 30 minutes of cardio seems pretty lame if you have any interest in overall health. I know a lot of Really Big people who do cumulative hours of cardio (weekly) even when off-season. Why would you not be good to your heart in this regard? It also won’t hurt the bodyfat levels, either.
