Dosages in Relation to Blood Results

Hi guys,

I was wondering if we could collect some data on what your weekly T dose is and what your corresponding serum and free T numbers are?

I started TRT a few months ago at 12.5 mg Test Cyp & 100 IU HCG every day. I wasn’t expecting anything as 87.5 mg a week seems very low to the typical numbers I hear about online (150-200ish), but my blood work showed I had a serum T of 1154 ng/dL and a free T of 44 ng/DL

I’d expect that if I had 150 mg that i’d be at near 2000, but I’m not sure if it’s a linear relationship between dosage and actual blood numbers.

Fifty random patients.

Wow that’s crazy. It’s almost like every human is a little different and we all react differently to different things.

Of course, we know that’s not true, but super cool chart.

Two guys that both feel great.

This is great to see. Helps paint a good picture of the many faces of TRT. Many thanks for this!

Are these bloods taken at nadir?

Yes, except where indicated otherwise.
