caber is like baby1 said its for prolactin. if you are having issues reaching orgasim it is going to make it worse. if reaching the peak is an issue you very well could be having prostate issues. if you do some research on caber it can cause heart valve problems when used at high dose and for long periods of time. so using it to aid in sexual function is a risk to me and it does take some time to build up in the system and take effect. some say 2-3wks and most go with a .5mg dose on mon and thursday. caverject is a entirely different compound
