I've been popping half a gram of l-tyrosine with my t4 each morning, temperature rises much faster. Reading 98.x most mornings by 7:30. Any drawbacks to this?
I'm almost 50 now and have been training - running, weight lifting for 25 years. I'm fit, probably 12% BF.
I don't run long distances. I do a 20 minute trail run once per week and a few hill sprints at max effort on another day.

Mine sits around 96.3

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.
