Ok so It's been awhile since I've been on here but I'm currently running 1500mg of test with 700mg of npp along with .5mg of prami and I have been running 2.5mg of letro to kill the tiny lumps I had and I've been running that for about two months now along with 500iu of hcg. I noticed my sex drive went down a little when I started the letro but now it's really low and It's hard getting it up my erections are kinda limp. So I figured my estrogen has just gotten way to low so currently I haven't taken any letro for about a week hoping my sex drive and erections will return. Anybody else have this problem and how long until I'll have my sex drive and erections back. I figured as long as I keep running the test it shouldn't take to long but I've never had this problem so I don't know.
