    Nandrolone Experiences

    Thanks, @Gman86, My heart rate elevation is relatively minor, and I'm rethinking how much of it is likely due to Nandrolone. I know from experience that alcohol, eating too much before bedtime, and overtraining will all result in a noticeable change in my sleeping heart rate. I'll try to...

    Gene's Nitric Oxide Stack

    It's commonly recommended to supplement Arginine with Lysene to avoid adverse effects from Epstein Barr, Shingles, and Herpes viruses. Does the alternate pathway of Citrulline to Arginine mitigate this risk? Or would additional Lysene be beneficial? If so, in what amounts/proportions? What...

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.
