Good morning Nelson, new to site. I'm 61 yr-old and having issue with ED. I'm in the medical profession and LOSS!!! Problem started that I noticed about a yr-ago( but could of been longer). I've been disenchanted with recommendation given.... I live in Florida and seeked help after I saw a TV new's segment on treatment of ED, I underwent their recommendation(Gainwave, PRP) and thousand dollars later, nothing helped.. Later was informed my Testosterone was low(TT 250, FT 4) and they recommended TRT . Skeptical obtained a 2nd opinion. Lab's were reorder from a on line service (never seen doctor ordering Tx) but accessible on the phone. My repeated labs TT 328, Estradiol 13.6, LH 6.7. I started TRT on 09/2017. Since starting TRT do have morning erections but not sustained long enough for penetration. My drug regimen:Testosterone Cypionate/Anastrozole 200mg/1mg 200mg wk'ly..HCG 500iu twice a wk SQ., Cialis 5mg daily..My recent Labs 07/2018 TT 916, FT 23.7, E2 50.6, PSA 2.3, PL 31.5(which I ordered on my lab orders, after reading your post on your site). On my follow up appointment discussed elevated PL with my doctor and given a script of Cabergoline 0.25 wk-ly as per your site recommendation..Because of my failures in bed given a script of QuadMix which i have used twice with good results but wound like to find out the real problem. A colleague friend of mine performed a US a results were NORMAL CAVERNOSAL ARTERY STUDY;VENOUS LEAK.... Nelson or Gene HELP ME....
