Likelyhood of boldenone significantly increasing hcrit? High.
Likelyhood of 1andro? Relatively low.
I wouldnt be too concerned with dhea compounds or even most designers unless you are polycythemic, or already have high range hcrit and platelets. Cos thats the really lethal (at risk) combo: thick blood, lots of platelets, plus throw in some sh1tty ldl numbers (almost innevitable on-cycle).
Also consider, again if you already have healthy in-range numbers, youll only run these orals for up to 8wks. Not like 16+ weeks of boldenone.
Get some nattokinase, vit d, and k2. Good basic "insurance" for arterial health.
