Tadalafil [off-label uses]

I have never looked this up but have heard all my competitive life about "deca dick." I have always heard that deca causes the sex drive to hit the floor. I believe what I have heard is may cause high prolactin. Of course this is based strictly on gym talk, never looks at any research in this area.

Vince did post this in 2020, I think the video pretty accurately explains deca dick.

Thanks dude! Yea I never researched it either. I didn't believe in "Deca Dick" mainly because lots of side effects that guys warn of, I never experience.

My Defy bloodwork [baseline before they took me as a patient] showed my test at 80ng/dl and prolactin high, out of range. And no boner issues at all, not even once.

[PS] I just remembered there was one time, with Adderall, before I was into lifting. I took an extra to help me on some huge paper. My junk was cold and definitely wasn't fully hard w/ my GF...like we still managed to do it but it was at 70% normal. So I did experience an issue once. Always meant to research what that was all about, this was 2008.

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.
