    Testosterone Cream- Scrotum VS other areas

    Did you do DHT? Would be interesting to see the DHT difference between scrotal and inner bicep applications. I've done scrotal at various amounts and my DHT was off the charts each time. My lowest was 1 click (50mg) which resulted in a DHT of 287ng/dL (top of range is 65). I'm doing inner...

    Starting on TRT Compound Cream and Joining the Forum

    Ive been doing it for a couple of weeks now. 4 clicks (50mg each/200mg total). Feeling less wired. I assume it's because of less DHT. I'll get some labs done in the next few weeks.

    Starting on TRT Compound Cream and Joining the Forum

    Ive tried cream, pellets, injections and now compounded gel. When you apply to scrotum your numbers will go up, but watch DHT levels. Mine were very high. Now trying on biceps and inner forearm.

    Testosterone Cream- Scrotum VS other areas

    Too early to judge how I feel. E numbers were high on prior labs with gel on scrotum (70).

    Testosterone Cream- Scrotum VS other areas

    E2 on scrotum was 5 but I as taking aromasin, which I stopped. E2 non scrotum was 32 but it was not sensitive, so not sure my E levels help at all. Went back to injections and now back to gel last week. Too early to judge how I feel.

    Testosterone Cream- Scrotum VS other areas

    When I first went on TRT about 8 years ago I tried regular cream and Axiron and didnt absorb. Atrevis gel definitely much better. I have also tried pellets and been on injections for a long time.

    Testosterone Cream- Scrotum VS other areas

    I have. One click (50mg) atrevis based compounded gel had by T levels at 888, FT at 211 (35-155) and DHT at 287 (12-65). Labs done 9 hours after application. 4 clicks total on my biceps and inner arms had my T level at 1026, FT at 21 (7-24) and unfortunately, I did not have DHT measured...

    TRT and penile blood flow

    High T can lead to high norepinephrine which will constrict blood flow. Lower dose, split into smaller more frequent doses and/or try an alpha blocker (flomax/doxazosin).

    Pregnenolone IR vs SR

    Which progesterone cream do you use? 20mg-40mg nightly on scrotum before bed sounds like a lot. How do you currently feel? Thanks

    Gel vs injections

    My results have been all over the place. E too high and too low. There was a longtime poster here (Phil?) who measured his E by his EQ. When strong nighttime wood happened, that was the right E spot. Ive tried to mimic that but its hard (pun intended LOL) to do.

    Gel vs injections

    We sound very much alike re DHT and E. I'm on and off HCG. I have better EQ without it but then my testicles and flaccid hang are small. I believe E can be an issue. I have both arimidex and aromasin and have trialed some here and there in search of the perfect spot. Im taking Pure...

    ExcelMale members thoughts on dim?

    Thanks for that info. What's your DHT at? What's your Free T at? Libido? EQ? What is your age? Do you have any BPH symptoms? Why no hcg? Im always on and off hcg. Like the way it makes the boys bigger and flaccid hang, but seems to raise my E levels and I have better EQ off HCG. No DHEA...

    Gel vs injections

    Your DHT sounds a lot like mine. I was only on two clicks per day and my DHT was in that 360 range also. Are you on injections? My DHT on injections is 100ng/dL (60 mg T cyp twice per week). Not as bad as 360 but still quite a bit over range. Started taking Pregnenlone to increase...

    Gel vs injections

    DHT did come down when not on scrotum, but still very elevated and my free T dropped significantly when not on scrotum.

    Gel vs injections

    BPH increase, E was also very high. Poor EQ. Generally not feeling great. My DHT was over 4 times the upper limit.

    Gel vs injections

    I started with gels, went to pellets, then went to injections, then back to gel (Atrevis base) and then back to injections. First gel on inner arm was not absorbing. Pellets I couldn't control and sometimes would pop out and you had a bump under your skin. Injections were good but I wanted to...

    Progesterone Dose for Men

    For those applying progesterone cream scrotally, do you apply once a day or twice a day? I have read sites that state to apply twice a day, but it appears that most apply once a day before bed. I have read conflicting info on half-life of the cream, 30-40 hours and there is a site stating...

    Pregnenolone IR vs SR

    Wish I would have. I did have DHT measured when on preg raising my prog level to .7. DHT was still over the top at 100 ng/dl (top of range is 65). I have been over the top on DHT no matter what my protocol or delivery method (injections or cream). My total T is usually in the 700 range with...

    Pregnenolone IR vs SR

    Have you measured your pregnenolone level when using progesterone only? If using progesterone only will your pregnenolone levels be low? Don't we want good pregnenolone levels? I'm with Defy and they always measure my pregnenolone level. I was using prog cream only and did have good morning...

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.
