For me ..... I don't really " feel " any different on it , i know of guys who stay on it just about year round for various reasons .
I played around with dosages till i found the upper " boner " limit , for me it was 150 mg and they were calling me Mr Handy ... LOL
Body weight and tolorance will determin how each individual reactes to it , like i get a real sense of well being on d-bol yet my training partner does not . So it depends on the person alot
