Alow me to answer your question.
First let me start by saying I juiced from the summer of my sophomore year until my senior year, but I did it in cycles.. AND I didn’t take horse steroids (winstrom). I took pure testosterone with breaks in each cycle built in.
(Its pretty funny that on my drivers license it says i’m 130 lbs, but at one point i was 198. - i’m now 190)
I also did PE at the same time i was on roids one year. I noticed that, a) It seemed to help my gains (My first experience with PE i did not use roids). and B) it helped me achieve a somewhat erect cock almost all of the time. As well as leaving some stretch marks, slightly increased acne, and a short fuse.
So to answer your question, I have no doubt extra testosterone does help with PE, As I have first hand evidence it does. However just taking roids and not doing PE you might only become more erect, or have un noticeable gains.
I personally had NO negative side effects from taking roids, other than increased acne. However, I was smart and drank a shitload of water while i was taking them. A good indicator is that my urine was never bright yellow because of the amount I drank. I would not be overestimating to say I drank a gallon of extra water a day. Infact, one of my coaches actually carried a milk carton filled with water and drank it every day.
I’m not suggesting anything- just offering my 1st hand knowledge of this subject.
