I've been on TRT for around 7 months total, the last few months on an increased dose of 200mg cypionate per week (100mg 2x per week.)  I just had my DHT tested for the first time.  Result:


DHT  816  (Range: 112-955 pg/ml)


So I'm within the reference range, but right near the top. I have noticed a big increase in body hair, particularly on my back and upper arms, since increasing my testosterone dosage.  I also think (but am not 100% sure yet) that I'm noticing some thinning along the front of my hairline. Obviously I don't want this to happen.


To complicate matters, I've recently (after the blood was drawn for this DHT test) added HCG to my protocol. I understand this can increase test and e2. I assume it also increases DHT?


Could a DHT level of 816 cause hair loss?


Would cutting down my testosterone dose be the best move here to reduce DHT and stop hair loss?

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.
