    TSH Labs / Hypothyroidism

    Has anyone heard of estrogen levels, and/or the use of an AI being responsible for thyroid issues?

    TSH Labs / Hypothyroidism

    That sounds like solid advice. I have read an iodine deficiency could be the root. Until I can get labs done, what type/dose supplement would you recommend to start the restoration process?

    TSH Labs / Hypothyroidism

    Can some please take a look at my TSH lab by Quest, and tell me if this is ok? I can see that it looks to be in range, but I’ve read in various places that it’s high. Thank you in advance.

    Subcutaneous Injection

    Interesting development - on Saturday night I injected 70mg IM. I started to feel better on Sunday evening, and felt pretty good last night. This evening, 3 days later, I’m starting to feel excessively tired, a smidge moody, headache, etc. - exactly the same way I felt when I wrote the post...

    Subcutaneous Injection

    Lots of good information, thank you. Would anyone care to make a dosing recommendation? It’s been 6 weeks, so I know my T levels are stable, and I think I have a pretty good AI plan in place. I would like to be in the 1k total, and 3.5-4 free. I am considering going back to IM 65mg x2 weekly, or...

    Subcutaneous Injection

    Thank you for the advice. What are the challenges with the midline? I switched in an attempt to mitigate the challenges associated with high estrogen. While it has certainly lowered it, my free and total T is considerably lower too. I just got labs back this morning, and it looks like I’m stable...

    Subcutaneous Injection

    That’s good to hear. I thought maybe I had been improperly injecting, and maybe it caused my T levels to tank. It doesn’t make sense. I went from Superman to bone crushing fatigue, weakness, sleepiness, etc. at the drop of a pin. It’s like my gas tank ran empty, and has stayed that way for 2...

    Subcutaneous Injection

    Everything else is good, no issues. It was just weird that I was Superman throughout the day, and then mid-workout Friday everything went to garbage.

    Subcutaneous Injection

    Thank you, for your insight. I’m at a loss. I feel like garbage - like I don’t want to get out of bed, I’m so weak it’s taxing to lift my arms, I just want to sleep....a lot.

    Subcutaneous Injection

    5.5 weeks ago I changed my dosing from 140x1 IM weekly, to 70x2 SC. I am a relatively lean guy, so it’s hard to tell if I am getting the needle into the fat. What happens if the oil goes into the space between the muscle, and the actual fat layer? I am asking because I finally hit my “sweet...

    thank you. I would have expected my dr. to know that. He’s a true TRT dr. I guess nothing is a given.

    Subcutaneous Split Transition - Complete Labs

    I posted a couple weeks ago, seeking advice on managing my dose, and transitioning from a 140mg weekly IM injection to a 70mg 2x weekly sub q regiment. I feel like my estrogen is somewhat stabile with .15 Arimidex at injection time. The labs support this notion. It’s only been a couple weeks...

    Sub Cuetaneous Transition

    I received partial labs today: Quest Diagnostics 1.61 Free 776 Total 18 Estradiol This was exactly 3 days after my last .70 injection, and .35 adex. At the time of lab work I have been on .7 x2 weekly for about 3 weeks. Looks like a pretty big drop in test free/total. Wouldn’t this cause...

    Sub Cuetaneous Transition

    What does everyone suggest to start? I’m at 70mg cyp x2 weekly. I’m considering dropping the adex to .15 at time of injection. Thoughts?

    What do you think the liklihood of the change to split being the source of my symptoms?

    Good call - I will pull my last labs. How long does it take to adjust/stabilize when switching to split dose ?

    Sub Cuetaneous Transition

    I have been battling high estrogen, for a few months. After posting my challenges on here, I received great advice - split my dose of 140 weekly, in 2 - 70 mg doses. I started out by doing .35 dex at injection time and I tanked, went to .25 tanked, so this week I didn’t take any with injections...

    I don't have to wait, I can go get them at the drug store. Taking into consideration I injected last Wednesday evening, when should I start the 2x dosing?

    How would I make the transition to 2x weekly from my current 1x weekly? I injected on Wednesday night.

    What do you mean? Is it not mixed evenly, is it a bad product? I have arimidex, but it's too hard to split evenly.

    HELP - Beyond miserable

    More labs as in more estrogen labs, or more labs as in additional types of labs? If I split the dose, is there a specific syringe I should use? What I am currently using has hash marks at every .2, making it impossible to inject .70 x2. If I were to do that, how should I make the transition? My...

    I have continued to look back at my training log, and it shows I was in extremely poor condition on 9/29, and absolutely killing it on 10/06, 10/10, & 11/04. I felt like that might bring a little clarity. I find it a way to look back, and see how I was feeling.

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.
