    Latest labs

    I inject 125mg/week divided into two injections and 1000iu of hcg/week divided into two injections. The hcg injections happen 24 hours before the T injections. The basic stuff looked good but a few things popped up as high or low. LH and FSH low .1 and <.2 respectively - guessing this is due...

    Which labs to order

    Started TRT 4/17. Last labs, blood draw was at my trough, had my T at 814, E was within range, everything else was within range. Labs were done 9/17. No specific thyroid testing that I remember. Both times I had labs done I used the TRT follow-up panel.

    Which labs to order

    through discountedlabs? Since my last labs I have added HCG and Tadalafil to my regimen. My main complaint is a loss of sensitivity in the equipment. DL has a Pre-TRT and Followup TRT lab. The pre TRT panel is pretty expensive though. Last, should I add a Prolactin test to the order and...

    Do you tend to build up a tolerance to testosterone TRT?

    I know when I first started I could have launched a rocket to the moon with my morning wood. Libido was off the charts. Wife was getting tired of telling me to get off her. I put of good weight, great energy, just felt good overall. I was getting stronger at the gym. Then I plateaued and I...

    Do pde5 increase length of intercourse time or could it be tied to estrogen

    I have noticed that since starting TRT my equipment has lost sensitivity making it almost impossible at times to finish. Sex had become a chore instead of a pleasure. We were having sex almost daily and I think was Vince that suggested the frequency could be a contributing factor. A week ago...

    Labs look good but libido is still shot; help!

    Ugh, T therapy is so confusing. I have read in other threads that an E above 35 is too high and causes issues.

    Labs look good but libido is still shot; help!

    So if my T was 879 and my E was 25 that would make my ratio 35.16? If a recommended ratio is between 14-20:1 does that mean I need to lower T or raise E?

    Loss of penis sensitivity, achy joints, dull orgams

    So my next question is when to pull labs. I am waiting six weeks before doing so since I added HCG into my schedule but should I pull labs at my trough or peak? Last time I did trough and my T was 879, Free T was 21.3, E was 25, SHBG was 26. Thinking about adding a Prolactic test next time...

    Loss of penis sensitivity, achy joints, dull orgams

    Much thanks to MM and Saul. I do not think the ED issues are being caused by the overdosing of zinc. I did some research on the side effects of too much zinc and ED was not listed. The mental weight of "will I be able to perform" pops up every time we climb into bed and that is no doubt...

    Loss of penis sensitivity, achy joints, dull orgams

    Just read the bottle, 455% of RDA. Add the 73% of my RDA my multivitamin was giving me and I was taking over 500% of the RDA. Think I'll stop the zinc tabs

    Loss of penis sensitivity, achy joints, dull orgams

    We are having sex almost daily, sometimes twice in a 24-hour period. On occasion I have taken 10mg of tadalafil but the last time I took it it seemed to have no effect

    Loss of penis sensitivity, achy joints, dull orgams

    What are you seeing that makes you think I should lower my dose? Is it my trough T level being as high as it is?

    Loss of penis sensitivity, achy joints, dull orgams

    Splitting the injections in half is not hard with the syringes I'm using. The reason I do Sunday morning and Wednesday evening is that it's easier for my wife to handle my injection on Sunday morning rather than a Monday morning because I leave very early for work

    Loss of penis sensitivity, achy joints, dull orgams

    I started TRT nine months ago. At first the results were amazing, better energy, better libido, put on good weight, muscle definition and for the first time in a long time I just felt better about life. Things leveled off and over the past few months I am having issues. Just laying next to my...

    New guy with Estradiol question/problem

    Thin build, not much of a butt and I use the upper outer quadrant. When I first started I was using a 1.5" and doc said to go about half way in but that was with a 22ga. I order some 1" 25ga and fully insert. No vitamin D and I've never heard of DIM. I just checked my multivitamin and it...

    New guy with Estradiol question/problem

    The Labcorp paperwork says it was a sensitive test, is there a different test for men and women? I too thought my T would come back higher. I do my own injections and will be switching to 2X/week

    New guy with Estradiol question/problem

    Back in 2015 my T was at 484 and doc said that was fine and not knowing better I said okay. About four months ago I started back at gym but had little energy/drive so I looked into TRT. My GP started me on 100mg/week IM and in the third week I felt GREAT. Energy, drive, the wife was holding...

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.
