    TRT Peaks and troughs or steady levels. Which is correct?

    As @BadassBlues pointed out, the ebb and flow is what creates balance. For example, quite a few of us here have experimented with blends of medium and fast acting esters to create a spike in the morning with a trough at night instead of a constant state of CNS arousal 24 hours a day. I...

    T Propionate protocol

    Funk can you explain how the testing works with this Janoshik? Are individuals sending him samples to test? Or is he doing it on behalf of suppliers?

    New blood work after 12 weeks on 50mg/2x week

    Sounds like you are doing well with minimal side effects. One piece of advice - don't chase numbers that look ideal on paper. While ranges can certainly help guide you, we all respond a bit differently as you will see on this forum. Some guys feel great at 900 TT / 20 FT while others feel like...

    New blood work after 12 weeks on 50mg/2x week

    Great numbers on paper, but how do you feel? Are you getting symptom relief for hypogonadism? Any side effects?

    Impact of TRT and Supraphysiological Testosterone Doses on Biological Aging

    I have read quite a few anecdotes over the years about guys feeling like TRT makes them look aged. From personal experience, I think its the water bloating that does it, especially in the face with telltale circles under the eyes. On the classic cypionate dose of 100mg per week (E3.5 days)...

    Dialed in on Testosterone Propionate, How to Switch to Cypionate

    I recall that you are the Natesto connoisseur ! It seems like a combination of the "bottoming out" plus the E2 tail from the earlier peak (E2 follows T - one of the first rules I learned here!)

    My protocol managing hct and libido

    I had tried E3D before and now trying daily. To be honest, its not going well. I just feel like garbage on the stuff, even Pregnyl.

    My protocol managing hct and libido

    Good to see update from you MJ. Some of your previous posts about protocol change still resonate with me because the only times I've gotten flashes of libido on TRT were from dose changes (or when stopping TRT). The one recent exception was libido from low dose no tester T, in this case...

    7.5mgs daily labs

    You started the smart way. When/if the time comes, its easy to titrate up versus down.

    Updated Labs - Help Please

    Good luck Craig. That T blend might be the oddest one I've seen yet!

    Updated Labs - Help Please

    I would suggest getting new vial of testosterone or better yet a different brand. Either you are not delivering the T correctly as Funk mentioned or there is something wrong with the T

    Updated Labs - Help Please

    TT 706 ng/dL with highish SHBG 44.8 nmol/L on 20mg TC daily seems way too low. Something off there...

    New to TRT. Received first labs. Concerned and need help.

    Its a great discussion to have because Phil and Cat represent two different schools of thought. That's what makes this forum so invaluable versus the steroid culture chat groups. Agreed it would be better if posted in standalone thread. But damn I wish could have seen their discussion early...

    New to TRT. Received first labs. Concerned and need help.

    He lost me when he started talking about titrating up from 120 mg :D which he acknowledges will already put most men at top of range or even well above it. Its like saying one martini makes you feel good so why not two?

    New to TRT. Received first labs. Concerned and need help.

    While there may be other causes, these symptoms are very common for older men (the mid-50 doldrums!). It sucks but its the unfortunate reality of getting older. If you find the solution, let me know.

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.
