Have you ever researched the PGE-1 2MG

it is sold as a research peptide on peptide websites for pretty cheap wondering what doses and the effects are like on this stuff, I am assuming it is injectable? not sure though.
This is the Brand name of the PGE-1 : MUSE(R) (alprostadil) urethral suppository:The only FDA approved noninjectable localized drug therapy for ED
I just found out about it.
I was wondering because Avanafil 50mg Had zero effect on me.

I have good effect with viagra.
Cialis not so much.
Thanks brothers!
