New Blood Test After Starting Injections: Free T Through the Roof!

This was done through my PCP. Tomorrow I go in for my Defy labs that will be a different lab with different ranges. I'm kind of surprised my free T was so high and regular T is mediocre.

T 766ng/di 129-767
SHBG 23nmo/l 10-57
T free 208pg/ml 20-135

Any thoughts?
 
Your SHBG is low(ish), could account for the high Free T, your TT is nothing to write home about...was that a trough? How much Cyp do you use and how often?
 
Feeling a little weird actually, but better then Saturday. Hard to explain but maybe hypersensitive or anxious but I'm also taking many sups. Sometimes I feel fine so I probably have some added anxiety thrown in. I drank a lot of alcohol last Thursday and Friday so could be why I felt like crap Saturday. I was taking too much creatine so I backed off it and a few other sups. I go in tomorrow morning for more labs and E2 is one of them.

You're sure on the total testosterone range? 129-767. If that's correct, you're at the top of that lab's range. I had a number of very high free testosterone readings at the three or four month mark of therapy, then it resolved. No answer.
 
Hey thanks CW, yea that's the range I double checked. I know it's different then what I normally see. So I don't know if I would be at the top of other labs as well.

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.
