    They used Quest for the Free T and it clocked in at 76.2 with a reference range of 46 - 224. And total T at 524 with a range of 241 - 827. Thoughts?

    Whey Protein

    I really like the java mocha and the cake batter flavor is awesome! I typically use the 1/2 flavor option and think it offers enough taste without being over done. The owner, Dante, is the person responsible for the DoggCrapp training protocol and he formed the company to try to offer legit...

    Gene's Nitric Oxide Stack

    Testosterone levels by age

    Are the charts accurate? I've been reading here a lot and trying to educate myself on TRT. I have all of the symptoms that are indicative of low testosterone but I'm not sure if it's just part of getting older, in my head, or if it's a legit problem that could be helped by TRT. I'm 41 and just...

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.
