I did a cycle of it with nothing else, 50mg a day, 8 weeks then 75 for 4. Got no head aches or any other physical sides like lethargy. Likely had high BP but did not check it (stupid). Had a pretty bad amount of emotional sides including semi-serious depression. So did my brother (he said it fuc*ed him up!). I got good mass gains. But now thinking back on it, Test would have been a lot better. I did not bulk on it but was watching my diet strictly (but not cutting just staying lean) and stayed lean and gained mass without fat, and gained a lot of strength. I did not retain too much water (but some) but was also doing a lot of cardio.
Today I would leave it for power lifting or for athletics that need you to be emotional and mean as a snake, blue eyed devil, shark, hornet, or a pit bull read to attack someone, (football...). If I was on the football feild again and only cared about ripping people heads off and success and did not care about my future health, I'd be on 100+ mg a day!
I would not take it if in a relationship with a girl or married. Too much PMS like emotions from it (unless you want to smoke pot or something for that which I didn't and don't - but some do) . Others may have had a different experience with it. My 2 cents.
