I have just finished my first 5 mg vial of DSIP and can say that this is a great peptide.
The reason I used it is because I read that this peptide stimulates the release of LH (luteinizing hormone). I started using it right after I finished my PCT. After PCT, I recovered pretty good, my libido was great and my testicles were normal size. But after I started using DSIP, my balls have increased in size, even more, even my girlfriend noticed it. Also, I every morning I wake up with a boner, while I didn't have any morning erections on PCT or cycle. It is hard as hell and usually takes about half an hour for it to become flaccid again.
I definitely suggest trying this peptide to everyone who haven't recovered after a cycle properly or experienced difficulties in PCT. I think that this peptide is a great addition to any PCT.
