If you like the fullness and water retention by all means stay with deca.its all personal preference.The longer the ester the more water retentive it is.(higher bp,estrogen etc)npp much shorter estrogen less water retention.im honestly at the end of the day not a fan at all of nandrolone(npp,deca)i only run npp in tje off season and not for long.running tren along with npp/deca both compounds are nor19.trens binding affinity is bar none to npp/deca so you wont even get much out of npp or deca while on tren.id personally run anadrol50 eod 50mg if you like fullness and drop the deca/npp all together.far as dhb goes thats one of my favorite compounds in the world.shame sb doesnt carry it bit dragon pharma does and its insane dhb.at the end of the day to each thier own thats just my 2 cents.but yes by far if you choose to run anything run npp opposed to deca
