Has anyone seen any updates on Kyzatrex approval by Health Canada? All I can find is approval was expected by the end of 2025 Q2 and we are closing in on Q4
Do we understand the mechanism as to why the oral delivery methods do not result in the same rise in HCT as the IM injection pathway?At the 81st Annual Meeting of the Canadian Urological Association (CUA) Dr. Yafi briefly mentions that oral Tlando should be available in 2026 but nothing regarding Kyzatrex.
There is no titration needed with oral Tlando as it is a fixed dose 225 mg BID.

I frequently read comments stating that one of the benefits of transdermal is that it's less likely to push up HCT. Definitely not the case for me. I have more trouble with HCT using cream than anything else. I sometimes wonder what the most important variable is: rapid swings in levels vs. highest level achieved in a given time frame vs. high levels for a certain amount of time?
In any case, high HCT with cream is real.
I'm looking forward to trying oral T to deal with my high HCT. Right now I've reduced my dose and increased frequency to EOD. Coming down from 57% to 54.9% at first blood test post change. My next draw is at the start of October so I hope to see the trend continue downward. However, my baseline was 50% so I don't know how much lower I will go. Right now HCT is my only out of spec parameter.It comes down to the PK as the daily peaks are short-lived followed by much lower T levels returning close to or even baseline.
Your 2 daily peaks are short-lived and more importantly T levels are not high/very high 24/7.
Tmax is achieved 4 hrs post-dose followed by much lower levels returning close to or even baseline 8 hrs later.

If you are using a sensible dose and not pushing your FT too high and we are not just talking peak--->trough here as steady-state levels will have a big...

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.
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.
The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
