    New here

    Just joined the forum. I was looking for something gear more towards trt than bodybuilding, and it looks like this might fit the bill. I'm 26 and am on trt, but I'm still fairly new to trt so I'm hoping to get the help I'm looking for.

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.
