Oral turinabol has an a:a ratio of 0:100. this means it has no androgenic effects, and has an anabolic effect equal to testosterone. Halodrol 50 is designer relative of turinabol. With NO androgenic activity, it means no added aggression which is what gives you that edge in the gym
As far as creatine + cycles go, that is just my opinion. I feel that there are more reasons not to do creatine on cycle than to do it. Additional liver stress, cost, lack of results are the main ones. I figure that if you can't get the results you are looking for from the steroid alone, then its probably a bad choice of compound. Creatine makes sense to start again in PCT.
So I really think you would get more aggression from RPM, and likely will get as good gains from Drive as halodrol. Weight gain is far more controlled by diet than by compound. Its just that if you are gaining 2lbs a week, the right compound lets that be 2lbs of muscle instead of 1/2 lb of muscle and 1 1/2 lbs of fat.
