It's potent steroid and I think anyone serious enough about this game need to try it at least once. I found it decent overall, perhaps if I would have not read all the hype about it's crazy strength and mass gains, I would have had my expectations lower.
At 50mg/day it was ok, at 100mg it was where things started to get better and at 150mg is where it's full power, however side effects to gains ratio are better and I'd advise 100mg/day.
There are two camps, some say it's stronger than dbol, others say otherwise. I belong to the latter camp, dbol at 50mg/day is stronger than 100mg/day drol.
When we talk about lower dosages 30mg dbol is way more fun to take than drol at 50mg, the effect is greater too. Mg vs mg dbol is significantly stronger.
As far as weight gain I'd say it's similar to dbol, perhaps more inflated and full on drol, strength gains for me personally dbol as far as 1RM goes, if we talk about volume and power drol wins, I feel I have more left in the tank with drol.
What I didn't like about it was feeling like on medication instead of steroid, for example some steroids make you feel good, where as with anadrol it felt like I was on treatment. As for sides minor increase in BP, appetite was fine, pumped up all day, some lethargy towards the end of cycle. I took it for 5 weeks, overall decent steroid.
