Free T percentage

This is a tough one to find out among the typical recommendations and outlooks regarding optimal levels. I am really glad you found this out about yourself and shared it!

In retrospect I really wish when I went on injection I was started MUCH lower and increased until I felt well. Coming the other way, peaking and having to reduce dosage due to hematocrit absolutely sucks! In the process, I felt best with free T somewhere between 39 and 23 while it was a moving target during dosage reduction, though Free T may not have been the sole reason for feeling well. Reducing dose a lot farther for the last 8 months has been nightmarish. For me, to attempt to reach Free T of 10-12 just to find out seems like a recipe for disaster!
Really free t is all relative to how you feel. I have shbg in the 60-70 range and have been on trt well over 8 years and feel best with free to in the 10-12ng range with total t in the 6-700ng range. I’ve had free t as high as 45ng at one point and for me anything north of 18-20ng makes me feel like complete shit no matter what other labs are. I can tell you from years of mistakes that fixating on a certain lab value isn’t prudent. If you feel great with 1.5% free t then why on earth would you want higher.
The main reason to try to increase FT would be to improve erection quality. Probably 30% of the time I can not finish. Erection is lost or I stay hard and just do not orgasm. Typically if it is relaxed Saturday morning all is good. Weeknight is prone to failure. I do usually take 25 mg viagra or 10 cialis. Was in daily cialis but tore up stomach
 
Mooseman,

Are you taking any other medications?

I’m taking no other medications. Hcg and dhea are disastrous for me, I do better on t only. I was told from the beginning with my very high shbg I’d have to dose high. This for me was so far from the truth. I feel great at 60-70mg cypionate once weekly but that’s me.
 
You are unaware of what your SHBG is? What type of TRT protocol are you on Dragon?

I was unaware of what my SHBG WAS.

I don't want to derail the thread, but to clarify this was 5 years ago, I was taking Nebido, and mostly self directed. With nebido you don't change dosing though you could slightly alter frequency of injections.

I stopped TRT for two years, currently i am with Defy medical.

The last three years I have blood tests that included SHBG, my SHBG tends to be around 35-42.

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.
