I have ran dhb for 16 weeks from Jan to may. Pulled bloods in March, hematocrit was good, although I do donate regularly. But you're right keep an eye on bloods for sure. I've never had issues with hematocrit no matter what I run. But everyone is different.
Cycle was 500 test cyp, 600 dhb, added tren a last 8 weeks at 350. Wish I pulled bloods at end of cycle but waited till August to see where I was at to start another blast. The test and tren were stanny's, dhb I got from good friend that was tested by analyzer.
