Ok lots of hits and misses finally got my injection thing down still trying to find my dose.... I am using straight powdered alprostaqdil but truthfully its coming from china and not sure how strong ... so I find doing 20units then 30units then 35units gets pretty hard but sure not rock by far.. and last at best 45 min... still possible if she is well lubed I can get it in but not there yet..... is it the amount can I expect to get real hard at some point or is it the product is not there I hear trimix works better but why is it the other chemicals ?
