Sparks is definitely an improvement …
Sparks is definitely an improvement upon sildenafil alone. In my case I noticed less side effects (I have had mild skin flushing, stuffy nose, peripheral vision issues). Also in my case, my erections not only last longer, but I notice I have been able to get erections quicker (less refractory period) and can have multiple erections and multiple ejaculations in one day. Thank you for this product!
