After discovering muse (alprostadil) pellets I tried both simultaneously and found incredible results.I also use an erction ring that prolongs the erction. However it has been such a success I am suspicious and skeptical since it is too good to be true and I would like to know what harm this combination
may cause? After removing the ring my erection lasts about one hour and then subsides . Has anyone tried this combination ?

what harm can it cause?
