    Cabergoline starting dosage at 20 ng

    Hello, since starting trt my prolactin has risen to 20 pg/ml. It is causing ED/low sex drive and some nipple sensitivity. I was given cabergoline to help, however I'm not sure on the starting dose at moderately high level. I see most people start at .25mg twice a week, but their numbers are 3 or...

    Length of Testosterone increase with HCG

    Hello, guys. Quick question. How long does HCG boost testosterone before levels return to base line? I.E. If I inject 200mg of test on Monday with 500ui of hcg, when will the boost of test I see on a blood test just be from the testosterone its self, and not hcg? I've read a study on rats that...

    Yes, I refrained from sex and all. Not sure about previous prolactin levels. This is a new trt doc for me. The previous ones didn't ever pull labs for prolactin.

    High prolactin on recent blood test. What to do?

    Hello, ya'll. My recent blood test showed a prolactin level of 21.3. My TRT doctor wants to keep an eye on it and recheck in a couple of weeks, and if still elevated send me for an MRI to check for a tumor (great!). What should I do at this point? Wait? Take a supplement like vitex? Or go get an...

    High T dosage not working

    Okay, I'll have to sit down this next go around with the doctor and see what we can do about moving to 2 shots. Is it normal for midrange shbg guys such as myself to have problems with obtaining proper T levels with large dosages? Or does my body maybe metabolize it faster? Thanks

    High T dosage not working

    Yeah, fifty, I do feel like that is the case sometimes. It's why I left the first place. What's telemed? Do they take insurance? I've tried defy or primebody, they dont take insurance. It's just hard to beat that 25 dollar co-pay.

    High T dosage not working

    Would it be beneficial to start taking boron? Or if I'm low and not high could that cause more problems than it's worth.

    High T dosage not working

    Yes, I inject every Wednesday morning at a local low t center near me. I'm going to call and ask if I can get a copy of my labs. They just told me the numbers, I didn't see anything. This is my second clinic I've been to. I'm getting tired of this incompetence.

    High T dosage not working

    They didn't give me those #'s. I would imagine if there was a problem there they would have said something, but ya never know. If they are the problem, what could I do to help fix it?

    Hey y'all, to those on a therapeutic dose of 140mg, what is your average peak and trough levels? I just started doing weekly shots of 140mg and was wondering what my levels might be roughly. I know getting a blood test would answer my question, but I have to wait another month before they'll...
