Long time reader, first post (besides my intro). I've been on TRT cream since Thanksgiving. Two clicks in the AM. Just got my latest labs from Quest and looking for feedback.
Specific questions:
Total T is 434 ng/dL (MS, 250-1100 ng/dL). Free T is 68.4 pg/mL (46.0-224.0 pg/mL). The labs were...
Thinking about this more... If the goal is to test testosterone at trough levels, shouldn't it best tested when testosterone would be at the lowest level which would be immediately prior to the first application of the day?
When is the correct time to get blood drawn when using testosterone cream?
After reading a few threads, I believe it is five hours following the application but am hoping someone can confirm.
Many thanks in advance!
Hi, everyone. Adam here from the Los Angeles area - specifically, south of the Pasadena area.
I joined to learn more about optimizing male hormones overall. I've lurked for a while and have already learned a lot. Looking forward to learning from everyone.

Understanding Your Hormones
Estradiol (E2)
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.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
