    Endo says SHBG doesn’t need to be tested. Need advice

    If you really want to know your SHBG levels, just get the test done yourself. Self-pay cash lab costs are pretty cheap and easily accessible.

    What needle length for IM TRT? Thinking of changing from subQ to IM to feel better

    If you’re really lean, there really isn’t any difference between subQ and “shallow” IM. I use 29g 5/16 directly into muscle (I have very little fat). I do daily mainly because my SHBG is very low.

    Guys on daily SubQ

    ~18mg daily - gets me around 850-900 TT - low SHBG (about 12-15) - use 29g 1/2” needle into shoulders, glute - No HCG, No AI - no hematocrit issues - I started daily injections several years ago, originally thinking SubQ into abdominal fat - didn’t see any specific benefit to trying to hit fat...

    Pregnenolone, missing piece?

    The main (and perhaps only) thing I noticed was that for nearly the first time in my life, I would have more vivid dreams / remember them in the morning. Sometimes that’s a good thing, sometimes bad!

    After one week on Tadalafil

    I started at 5mg per day and had back and leg pain. Went down to 2.5mg per day and no pain, but still providing all of the benefits.

    Cypionate Dose Reduction

    How often are you injecting and at what dose? I do EOD and have done labs at 24 hours and 48 hours post injection- you might consider that to really get good data on what’s happening in your own body. Perhaps T levels are spiking more than you realize, which also causes e2 to spike? Just a...

    Cypionate Dose Reduction

    Nope - I’m pretty consistently about 120/80. Body fat about 13-15%, exercise about 4 times per week.

    Cypionate Dose Reduction

    Took 4-5 weeks to really get through it. I take 30mg EOD, no AI. Also now taking 2.5mg Cialis every day.

    NO MORE AI !!! FEELING AMAZING!

    SHBG is actually quite low (11 last test). Nearly five years ago when I started test, I had been put on 1 mg Arimidex per week. I’ve never felt worse in my life. From there, I’ve been experimenting and learning. My problem has always been that rollercoaster of feeling great and then crappy...

    NO MORE AI !!! FEELING AMAZING!

    I, too, quit AI six months ago. Doing EOD injections. No HCG. Best thing I ever did.

    Cypionate Dose Reduction

    I’ve had similar issues in the past trying to chase E2 and varying dosages of Arimidex. Finally figured that’s what was causing the roller coaster feelings. Haven’t taken a AI since December and it’s been by far the best six months out of the past four on T. Try to let go of the AI.

    The benefits of long term use of Cialis

    Keep looking at GoodRX for cash pay discounts; prices are really coming down. Just got 30 5.0mg generic at Kroger pharmacy for $23

    Someone with low shbg had little/no success with once/twice week injection, but ED/EOD?

    Started pregnenolone in January immediately after stopping HCG and AI. I had done testing for pregnenolone and my number was at the bottom of the Quest range. Hard to know exactly what’s its doing vs. stopping HCG/AI. I do know that I tried increasing pregnenolone from 30mg 1x day to 50mg 1x...

    Someone with low shbg had little/no success with once/twice week injection, but ED/EOD?

    I’ve got very low SHBG (usually 13-18). Tried weekly, 3x week, EOD and daily injections. Tried test cream on scrotum. Tried all different iterations of HCG doses and timing. Tried all different iterations of AI doses and timing. After 3-4 years of experimenting, and lots of lab work, I’ve...

    ED vs EOD - Any difference?

    Yes - about 32mg EOD

    ED vs EOD - Any difference?

    I did ED for several months. Switched to EOD and can’t say I noticed much difference at all. Given that, I’ll stick with EOD as it’s a little less hassle.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
