    How potent is old Anastrazole?

    I ran out of my current prescription for Anastrazole and every day since Tuesday, I've been taking some three year old Anastrazole I had left over from another medical provider. I've read that medications generally lose potency as they age but most don't go bad. Does anyone know if three...

    Has anyone used T cream to the scrotum along with injections and how much did it raise your scores.

    I've been doing the following: 60mg T cypionate M-W-F 350 HCG M-W-F .25 Anastrazole Monday thru Friday I wasn't getting goods results, especially in the areas of libido and sexual function. My doctor added what I think is 25 mg of T cream (2 clicks on a 50 mg/ml) applied daily to the scrotum...

    New lab results

    Moving from M-W-F Test Cyp to daily injections. How to calculate dose?

    Time frame for changes in Estradiol

    I'm currently taking 60mg of T M-W-F along with .25 Anastrazole on the same days. My current weight is 380 so I assume I convert T to E on a large scale. A couple of months ago I reached a point where I was sure I had high or low Estradiol so I called Defy for labwork and my Total T came...

    Quick question on TRT injection vs blood draw

    I'm currently on a 50mg T, .3 units HCG and .25mg Anastrozole, all M-W-F. I had T and E checked last week and they came back: Total T 845 Free T 22.7 Estradiol 20.0 I injected my 50mg of T about 6-8 hours before the blood draw. Are my T scores likely to reflect that or does it take...

    Estradiol - How Long to Recover After a Crash?

    I just started a protocol of 50mg T M-W-F, 300iu HCG M-W-F and .25mg Anastrazole M-W-F. My starting total T was 1200, Free T was 31 and Estradiol was 45. This was on 250mg T per week and 1mg of Anastrazole per week. My first few days on the new protocol I could feel that I was starting to...

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.
