Testosterone volatility
My testosterone was measured @ 490 in 2014 when I was DX with PCa Gleason 6, it was measured again in 2016 at 463. It was not measured again until after I started on ADT and it has been >7 ever since. Is there a way for me to extrapolate what it would have been in 2021 when I was DX with Gleason

Should the dose of Dutasteride be increased?
The plot above shows the residual (nadir) level of DHT in men as a function of the daily Dutasteride dose (mg/day). The DHT nadir numbers shown in this plot are: 23.8 pg/mL for 0.5 mg daily dose; 10.2 pg/mL for 2.5 mg daily dose; and 7.3 pg/mL for 5 mg daily dose. Ref: Clark (2004) [see Table

Low testosterone is associated with extremely poor survival metrics, post-ADT.
These companion plots compare: (A) median survival times, (B) PSA doubling times, and (C) Time to PSA Failure for two different levels of testosterone: Low and Normal. The low testosterone has a median value of 162 ng/dL [120-236] and the average normal T = 680 ng/dL. The cohort is 58 men with unfavorable

Low Testosterone reduces Survival by a huge amount.
This plot compares prostate cancer specific mortality probability versus time for two different levels of testosterone: Low and Normal. The low testosterone has a median value of 162 ng/dL [120-236] and the average normal T = 680 ng/dL. The cohort is 58 men with unfavorable intermediate risk who underwent

My own PSA values over time: 70% drop in just 3 months on Dutasteride and no ADT
Here are my own PSA values versus time plot. You can see there is an exponential rise in PSA starting at around 6/1/23, and doubling from PSA = 5 to 10 in about 8 months. My MRI at PSA = 10 showed a T3a tumor about 1.3 cm long (PIRADS 5). A subsequent targeted biopsy showed Gleason 3+4 in 4 cores,

Doubling Times and PSA acceleration - Part II
This is a more realistic schematic plot of PSA levels increasing over time at an ever faster rate (acceleration). What could cause this? My theory is that as the tumor grows, the number of androgen receptors (ARs) increases proportionally. That makes sense...more PCa cells inside a tumor...more ARs

Non metastasis castrate resistant
When you are on ADT and become Non metastatic Castrate resistant and your testosterone levels are below zero, what is the cancer feeding off to cause the PSA to still rise? Hoping for your replies so as to give me some understanding. Thank you.

low levels of T4 & T3 on 3 grains of NDT
Dear all, Again I need some help with my blood tests interpretation and further steps. I’m currently on 3 grains of thyroid-s and my results are as shown on the table below. Both FT3 & FT4 levels are not satisfactory. Could this be because of the low levels of ferritin, D3 and B12? Or do I need to

Increasing Gut Issues
Hiya.I am currently having increasing gut type issues with my current batch of NDT. When I increase the dose, which I need to for my levels to be optimum, I am getting increased belly swelling, painful trapped wind which runs from my throat down my oesophagus and abdomen. The last few days, my belly

Sourcing THYROID-S NDT
I am coming to the end of my supply of Thyroid-S NDT.It is batch no.TA21089,expiry date 12.24. From reading posts on here,I can see there are now supply issues. Been through this before with THIROID then TR Mann over the years . Please pm me reliable functional supplier information.

Revised Plot of PSA vs Testosterone: Estrogen vs Lupron ADT
Ugh...I made a BIG mistake on the previous posting! I just realized that Dr. Morgentaler had listed the Testosterone level in unusual units (

), not the usual units of (
ng/dL)
. So, my X-axis was off by a factor of 10. Here is the revised plot. The exciting discovery is that the

Another brother passes
My friend, George, passed this morning after a two year battle. He was DX'd at 85 with prostate cancer (PSA of 1200) behind his eye which spread to his brain. Failed ADT, chemo and Pluvicto. He was not on this forum. He was very active, skied 120 days a year, biked the rest. He and his wife went to

PSMA Scan to be scheduled - thank you Tall Allen
I want to thank Tall Allen for his suggestion that I see an oncologist. I had a RP followed by radiation in 2013. My PSA was undetectable until 2021, when it started to rise. This week I saw a radiation oncologist (whom I found through a friend) to ask him a lot of questions and to get his advice.

T3 only worth another PROPER go?
Okay so I made a post last year about being unable tolerate t3 only but I’m actually wondering if I jumped onto t3 mono too quickly and gave up too fast? (Which many others pointed out but at the time I was so unwell I could barely think straight) Prior to starting T3 only back then I was on a too
