    High SHBG - any way to lower?

    I recently was able to view lab results from 2018 to present day. Every time I have had lab work done (hormone panel) my SHBG is always higher than it should be. The higher than normal value presented even before I tried self prescribed TRT. 2018 (prior to testosterone) - Testosterone 26.9...

    What to ask for...

    Libido Supplements

    I have posted on this board in the past regarding TRT and libido. I had briefly dabbled with self prescribed TRT a few years back. It was initially amazing (honeymoon) with regards to energy and libido but that quickly paled in the face of the negative sides I experienced. I ultimately stopped...

    No libido, unable to orgasm

    So I've been off testosterone for four months. Didn't do much of a PCT. Tried clomid briefly - it was awful, tried a few test booster and "pct" supplements - who really knows if they work or not. I'm not feeling awful but I am feeling sub-par. Still trying to work out at least 5 times a week...

    Supraphysiological test levels after stopping TRT

    I am throwing this question to the vast amount of knowledge on this board. My last Test-Cyp injection was February 4th (75mg, shallow IM, which I had been injecting weekly for less than 2 months). I had started low dose clomid (25mg eod) but stopped that 4 weeks prior to scheduled blood work...

I don't mean injection site issues like redness and inflammation but systemic hive like, extremely itchy raised lesions on the back, chest, right and left flank. I have been off TRT for a few months now and the issue has increased. The...

    Appropriate duration of Clomid use post self prescribed TRT

    Just throwing another question to the masses. I am currently into my third week of Clomid only, post a two month (or so) duration of self administered TRT (75mg weekly test-e). I started a week after my last injection with 12.5mg of Clomid daily (week 1) then upped it to 25mg daily from week 2...

    Weekly Injections

    I currently inject 100mg Test-cyp weekly. Shallow IM. Every Friday. I have been finding lately that the few days prior to my injection is when I am feeling the best.

    Libido...to titrate up or down while on TRT?

    Just wondering if anyone else has had the same experience. I am "self dosing" testosterone cyp. Weekly shallow IM injections of 87.5mg. The first 3-4 weeks were great. Libido and energy took quite a jump. Going in to weeks 5-6 things started slowing down, especially the libido. I have read in...

    Question about Test and dosing

    Does exogenous testosterone, no matter the dose completely shut down the natural production of testosterone. I was talking to a physician about this at one time and he said no it doesn't. But that is in contrast to a number of articles I've come across. If a person (say age 53) self prescribes...
