Thread is a bit old, but I would like to chime in: HCG will jack your e2.
A few months ago, I discussed my strategy for getting my wife to lose some weight was, A, to lose some myself (lost 16 lbs....did my first real cycle in 8 years, so I also built some muscle) and B, stop initiating sex.
Towards that end I did a HUGE amount of EQ and deca (more than 1kmg a week for each, for 2.5 weeks). Sure enough, it killed my sex drive. I went off my last cycle a few weeks ago, and ran 2k IUs of HCG eod. I had a small amount bof Letro, but it ran out before the HCG did. I figured "well, lets see if I am OK just taking some Nolva.
Boy was I wrong. I have been having erectile issues for a few weeks. I purchased some Letro from Meso (good stuff) and am on my third day.
Well, the wife has not lost much weight[

)] but my ED seems to be gone, as I had a satisfactory date w/ Rosy palm and her sisters.
Of course having too little estrogen is also a problem. That is why I don't rely on labs (w/ I get only every 6 months anyways) but purely on Mr Johnson. I just remedied a situation were e2 was, I am sure, too high. Now If I started taking lots of Letro, it would probably become too low, which also causes ed. It is always a fine line, but the proof is in the penis. A small amount of Letro eod works best for me.
To you young guys, you have my sympathy. Man, when I was 30, (when I started using gear) I could bang all night. I am 50 now, on trt, and the stars have to line up correctly. It must be especially tough on the young guys who have these problems.
BTW, Cubbie: You are taking very, very tiny amounts of Test. I need 200 mg a week for good results. You can take that much and be healthy for the next 60 years. Gear, if used responsibly is not as dangerous as all the hype make it out to be. You just have to follow a few rules, 1: Don't use before 25 as the brain and endocrine system are still developing, and 2: Take as much time off as on. I am referring to full blow cycles. Say you run 350 Mast, 350 test, and 250 var a week. You are on that for 6 weeks. You then drop the var and mast, I also like to drop the test back to 200, and then HCG (unless you were using it on cycle) followed by a full pct (Clomid/Nolva). The pct can count as time off. Discipline yourself to take 5 more weeks off, and you will have a healthy and still performance enhancing lifestyle..
