The side effect is different with everyone I think.
PT-141 doesn't comes with negative side effect for me currently.
But it is true, positive effects neither comes together just a few.
Last time I injected 1.2mg at the morning 2 days ago. I am waited an hour, there was not any effect, so injected an other 1.2mg. I am waited all day, watched myself, but there was not any effects daytime. Nothing positive, nothing negative.
In the night.... I woke up 2-4 times, because needs to go to piss, every time my penis was erected, not rock hard, but was enough hard.
The last erection was really rock hard in the morning before I got up.
My penis strongly throbbed. The pc muscles stretched and moved it in every 3 sec which was very good feeling. After half hour still was rock hard, so I decided I need to get up to masturbate. So I got up and went down for a coffee. While I drank the coffee my penis went down to a bit soft. I started to watch some porn and I got back the rock hard erection. After an hour I couldn't hold back myself, so stood up to start ejaculation.
The first 3 shoots was the strongest and flew away for 2-2.5 meter. It's unbelievable I know, but it was true! The following 10 shoots was smaller, but I pressed out really lots of semen, what quantity never comes before.
Then started the refractory period, normally it is 2-3 hours with me.
But at this day was only 5 minutes and I got back an other hard erection. I was really surprised and very happy. I was very aroused again, but I couldn't ejaculate because my time is gone and I went to work. Since that time I haven't got spontaneous erection. So those are all of mine positive effects. The only negative effects was the night erections. I wanted to get them in day time. But day time nothing comes.
