PARTICIPATION NEEDED!

Of those EM members that have taken nandrolone or are currently taking nandrolone alongside their TRT, we are conducting a small ExcelMale study to help determine the effect that nandrolone has on Total Testosterone, E2, Prolactin, SHBG, free T, and DHT while taking TRT.

Here is what is needed:

Simply post the following information...

(1) Pretest Labs (Labs taken before adding nandrolone to TRT):
TT
Free T
SHBG
E2
Prolactin
DHT
Blood Assay Methodology
RX Protocol

(2) Posttest Labs (Labs taken during nandrolone treatment):
TT
Free T
SHBG
E2
Prolactin
DHT
Blood Assay Methodology
RX Protocol

Let's move our knowledge forward!

By the way, @DS3, Thank you for the poll and interesting question!
I was prescribed nandrolone last year for my achy joints, it definitely increased my HCT and HGB, bummer I had to stop using because my HCT was at 57 and my hct was at 19, i did donate but within 4 weeks i was right back to beinh thick again, used a low dose, just 40mgs a week. I would love to use some again, sure helps woth qaulity of life....would it benefit me to lower the test dose from 100mg a week to 80 mg a week and add 40mg of nandrolone?

What would benefit u way more is to be better hydrated. HGB and HCT has a ton to do with hydration. I’m using doses of both test and nandrolone much higher than u were, as well as using primo on top, and my HCT has been running around 48-50ish. I believe it’s cuz I’ve learned how to optimize hydration pretty good. Here’s a vid that made a huge difference for me in regards to hydration. Been drinking mineral water with added Celtic salt and liquid magnesium chloride added into each bottle ever since I watched it. Has made a huge difference

I would say yes a lower dose would have a lower impact on HCT.

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.
