Curious madman where you get the comments of absurdly high? In most optimized communities TT of 30-50 is recommended. We all now the lab ranges are a complete joke. Based solely on my on knowledge of watching them over the last 13 yrs of being on Trt and through this site. Yes i give blood regularly every 8-10 weeks and have since i was 18 and had just donated a week before this test. Im truly interested in what you think i should be looking for numbers wise and where you get that info from. I increased my vitamin d 5,000iu daily after this also. Yes im big guy but according to dexa i have 227 lbs lean mass and 22.4% body fat. I look forward to more info you have and research to follow up on.
I stated that your trough FT (7 days post-injection) is going to be high with a robust trough TT 776 ng/dL and low SHBG 16.2 nmol/L which means that your peak TT and more importantly FT will be absurdly high (almost double) 8-12 hrs post-injection during the first 2-3 days every week!
If we calculated your trough FT using the linear law-of-mass action cFTV you would be in the low 20 ng/dL which is high!
A trough FT 30-30+ ng/dL is absurdly high compared to where a healthy young male would sit 12 ng/dL
(paper posted thread below post #23) and this is tested using the most accurate assay, gold standard direct state of the art ED LC-MS/MS assay in healthy men, blood drawn in the early AM!
Again outliers are the ones that would be hitting the 90-95 th percentile and this would be far and few.
We present 95% mFT age-stratified reference ranges
Age category (years) |
Median mFT (ng/dl) |
95% mFT reference range (ng/dl) |
18-29 (n=140)
30-39 (n=252) |
12.0
9.8 |
6.7-25.3
4.9-18.5 |
Even if you took a natty outlier hitting a high FT 20-25ng/dL this is a short-lived daily peak we are talking about here not a trough let alone trough 24 hrs (daily), 48 hrs (EOD), 72 hrs (M/W/F), 84 hrs (every 3.5 days) let alone 168 hrs (7 days) post-injection!
You get the point here!
Top it off that there is no such thing as a natty healthy young male running around with a peak let alone trough TT 1000+ng/dL and more importantly absurdly high FT with low/lowish SHBG, such does not exist!
Most healthy young males are hitting a TT 500-600 ng/dL (peak), even going back to the 70s when testing was first available you would be looking at 600-800 ng/dL.
Take those TT 500-800 ng/dL (daily short-lived peak) and thrown in for shits sake a normal SHBG and calculate their FT using the go to linear law-of-mass action cFTV and none of these men would be hitting a peak FT of 20 ng/dL.
Top it off that cFTV tends to overestimated slightly compared against a standardized direct state of the art ED assay so FT would be slightly lower than the cFTV value given!
There is a reason we have a natural 24 hr circadian rhythm with T levels peaking in the early AM.
T was never meant to be elevated let alone amped up 24/7!
Bottomline here is if one feels great overall, minus any sides and blood markers are healthy than I see no issue running a high-end/high trough within reason.
You are clearly trying to manage elevated hematocrit if you are donating every 8-10 weeks as your RBCs and hematocrit are still sitting close to the top-end on your most recent labs and judging by your other CBC results you most likely crashed your iron/ferritin due to the frequent donations which can open up another can of worms.
Those knumbskulls pushing this so called magical optimal trough FT 30-50 ng/dL is pure nonsense.
Even than big difference between one hitting an absurdly high trough FT 30-50 ng/dL injecting daily vs twice-weekly vs once weekly!
A natty outlier hitting a top-end FT 20-25 ng/dL is high and again this is a short-lived daily peak we are talking about here!
You would be hitting a cFTV trough in the low 20 ng/dL and this is 7 f**king days post-injection!
So yes your trough FT is high and your peak FT will be absurdly high plain and simple!
Look over post #19/21/23!
Pay attention to post #23!
I've been on TRT for close to four months and am on 200mg/ wk of test cyp. I am doing ED injections. I am thinking of dropping my dosage by 20%. Any feedback would be greatly appreciated!! Thank you!
