Nothing is comparable to the above except for the now defunct Aspire. You can also try coq diesel. I liked it.
Icariins didn't work for me, I think they may only work for people with healthy test levels, as do most test boosters. Nothing works for hardness like cialis, best thing out there, even when low dosed. There are very little sides if dosed at 5mg ed and it's still very effective. Were you taking liquid cialis or the pills? The legit pills definately worked much better I found.
Also, try dosing l-dopa 30-60 minutes before sex to greatly reduce refractory time.
