Stanozolol is a bad choice for female, but if you want to do it, do it. It's your body, your choice, your consequences.
But...
Do you know why you did not succeed? I'm pretty sure because your diet and training were not correct or if they were, maybe you have a wrong idea about what kind results you can get.
Steroids are not magic pills that give us wonderful bodies without work. The job is still yours, you have to eat, train and rest right, the steroid potentiates the result of what is already correct.
Your atitute is typical for many girls, you don't do the basics and believe that failure is due to the choice of drug or dosage. So you begin to throw more drugs into the body with higher dosages. In the end you end up with bad skin, bad hair, thick hair all over your body, thick voice, swollen clitoris, you end up like a pubescent boy and yet the results are mediocre.
