If you’re struggling with high hemoglobin (185+) then you need to do 2 things: spread your dose out over 2-3 injections not one, and likely lower your dose for a while (ie 150 down to 100) and monitor for a few months. If it normalizes slowly increase your dose 10mg every month and watch to...
Forget about Hematorcrit. Its a percentage that can change with dehydration. Watch your HEMOGLOBIN levels. If they get too high (above 185) you are at risk of clots. Hematocrit is a useless reading.

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.
