    9 years on Gel - Switch to Injection - Effect on HCT?

    Hi, I've been on 1% Gel 1.25grams 4 pumps total for 9 years. Peaks are 2 hours after applying the gel. Generally in the upper 600's to low 700's total.

    What affects Test Level's when on TRT?

    Interesting, I am going to do an experiment and apply the gel to my ribs/abdomen for a month and then test my levels. I did some reading on this site and it seems applying it to the ribs/abdomen can increase estrogen in many men. So, it may not be a good idea. But if it does work well for me...

    What affects Test Level's when on TRT?

    That makes sense. I am curious as I now have 7 years of bloodwork. 6 years being on TRT. I've been on Testosterone gel 1% (4 pumps total) for 6 years now. Prior to going on TRT I tested my levels 3 times within a year. For those 3 tests my lab's were as follows: Total T was between 200-250...

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.
