    New blood tests. High estrogen? The reason I’m having low libido?

    My last post can be found here: Very high libido when I miss a dose... In that post I promised new lab results from Quest taken at trough (actually one day beyond my normal injection time, so “super trough” you could say). Here they are pictured below. Possible remarkable results/questions...

    Very high libido when I miss a dose...

    I inject 20 mg Test-C, 250 IU HCG, and 11.25 IU urofollitropin every other day. Been doing this now for at least a year. Probably closer to two. I consistently notice that if I miss a day, my libido seems to peak. But after 2.5 to 3 miss days I feel like I start to crash. Any idea what this...

    New here. Lurking for a while. Pretty sure my E2 is shot. Shitty docs. Here's my history.

    I've been on some sort of protocol for years now, and frankly I don't think it's ever been right. Started just after turning 26. I am now 30. I'll try my best to be short and sweet. I really just want help understanding why I feel so shitty. Also, any insights on why my acne was so bad would be...

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.
