My blood pressure borders on pre-hypertension so I watch it closely. I have found that 1,3 Dime, which is the primary stim in Jacked3d does not increase BP nearly as much as most other stims, nor does the effect wear off as quickly. If you've ever used a product like NO Xplode you will notice that it works great the first few times you use it but the effects quickly dissipate if used to frequently.
