When bulking you can expect to put on some fat but mainly muscle wil be added.Yes you will add water weight aswell but if you keep water intake high you will be fine i.e 4/5lt per day.Eat plenty protein to retain muscle mass and do this for atleast 1 month after stopping them aswell to help hold onto gains aswell as keeping calories high aswell

As vroom said if dont drink enough water liver and kidney damage can occur but i all honestly ive ran these at 50mg per day and ive had liver and kidney trouble in past and i had no trouble whatsoever so not as dangerous as people make out tbh.Ive also ran oxies at 150mg per day and suffered even less trouble and better gains but alot of water weight added in with that dosage but as i was running sust and deca alongside oxies and oxies were only kickstart i have actually kept most gains thankfully

Personally i prefer oxies as i dont loose appetite as i do on dbol but everyone is different.Some guys cant take sides of dbol like shin pumps,back pumps loss of appetite etc etc but some are like that on oxies.Its all trial and error really you dont know till you try
