I've been tempted to try such a protocol but have had negative experiences with nandrolone in the past. I've tried adding it to a test base, and every time I experience negative mental side effects.


Also, adding it to a test base seems to exacerbate my acne/folliculitis.


My E2 is generally high even when using a moderate, test only protocol. I've actually never had in range E2 the entire time I've been on TRT. Getting it that low requires me to adjust my test dose so low that there is no longer any benefit to being on TRT. Perhaps adding nandrolone to that high E2 environment is what causes my issues whenever I try it.


Curious as to whether or not trying the nandrolone base with a tiny dose of test would still produce the same negative side effects...

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.
