Point being stressed is extremely high levels of T are not needed to experience relief/improvement of low T symptoms period.
Healthy FT levels is what matters and the free unbound bioactive fraction of T of a male is 2-3% of TT.
Many can achieve a healthy FT with TT levels near or just above the top end of the physiological range and as was stated in cases of very high SHBG or possible AR resistance which would be if anything in older men or former steroid abusers than yes one would need to run a TT a lot higher (1500-1800 ng/dl).
Of course higher T levels up to a point is healthier compared to lower T levels but this higher T level is not to far off from what a normal healthy fit young male could naturally produce and yes we are talking about the top 2.5% of men which have TT levels in the 1000-1200 ng/dL range.
I will say that when looking at the main areas of low T symptoms sure higher T levels may enhance ones mood to a certain degree but running high T levels as in this greater than 1800+ range is not going to result in more energy, better mood, better libido, better erectile function and overall well being.
Even with healthy T levels many other factors can negatively effect ones energy levels and mood (thyroid/adrenal function, lack sleep, poor diet, excess stress (physical/mental), lack exercise and so on.....excess T is not going to cure this.
Even with healthy T levels as you know many other factors can negatively effect ones libido/erectile function (poor vascular/endothelial health, thyroid/adrenal dysfunction, lack of sleep, excess stress (physical/mental) and so on.....excess T is not going to cure this.
Again symptom relief is what truly matters but labs are still critical and we need to keep physiological levels in context here as reference ranges are guidance and sure we do not need to adhere to being in range but it is highly doubtful men need to be running around with 2000 ng/dL T levels in order to benefit from trt.
No healthy young males produces those kind of levels endogenously and to top it off there is a natural 24 hr circadian rhythm where testosterone levels peak in the am and decline (trough) in the late afternoon/early evening and we are not talking about peak levels 2000+ only to be followed by absurdly high trough levels.
At best most healthy young men have a TT of 600-800 ng/dL at peak only to be followed by a 25-40% reduction at trough and they function extremely well.
All hormones need to be kept in balance as testosterone is only one piece of the overall picture.
Sure you can use the analogy that well since my hpga is suppressed and I am now on trt.....might as well make the best of it and run the highest T levels because I feel best as you say.....but again one can say oh I feel best on 200 mg/week than all of a sudden I feel better on 250+ mg/week (which is not a replacement dose).
Call it what you may but 250+ mg/week is a low steroid dose.
Where is the line drawn between replacement doses when you know a good majority of men can achieve a healthy FT using trt doses in the 100-150 mg range.
Anytime we increase T----->e2 will follow and you very well know how many need to start tinkering with an aromatase inhibitor in order to run higher T levels without experiencing sides.
Any time we increase T as in 200 mg/week and higher it can negatively effect lipids.....mainly lowering HDL.
Anytime we increase T----->hemoglobin/hematocrit are increased and you very well know how common that is leading many to jump on the too frequent blood donation bandwagon
only to be followed by the all to common.....oops I crashed my ferritin/iron.
Sure hemo/hemato can be managed if done sensibly and even than most can let levels get a little higher than the reference range without issues but regardless if it leads to no immediate negative effects.....thicker blood is thicker blood and the heart has to work harder.
Big problem here is many are started on high doses of T 200 mg/week from the get go only to be followed by a negative experience in many cases or for the ones that tend to feel well never get a chance to realize that they could very well feel just as good on lower doses.
You see it all the time on the forums.....people thinking that more T is always better.
If you truly feel better running levels in the 1600-1800 ng/dL range so be it but do not come off as if these levels are needed to truly experience improvements in low T symptoms.
