yes it's true "Some" people can use D-bol without using an anti-estrogen and not grow tits. However the key word here is "some" The rare and the few might be able to pull this off. The question is, why the fuck would you even want to risk it? Arimidex is not that hard to obtain which means you are either lazy, broke, inexperienced or all of the above. you need to run an anti-estrogen so that you dont have tits when you are done with your cycle. Gyno aint no joke and gyno removal surgery is expensive. Also, D-bol has an extremely short half life which means you need to spread your 50mg dose up throughout the day to try and keep your blood levels stable. Your natural testosterone will be suppressed after being on D-bol for only 10 days so you can kiss your nuts goodbye. Do yourself a favor and do some more research.
This would be a better gameplan little brother
Test Enthanate weeks 1-12 400mgs weekly
Dbol weeks 1-5 35mgs dbol daily
Arimidex .5mg daily (you could probably get away with .25mg arimidex daily but I prefer to be extra cautious)
Followed by proper PCT
