Question about DHT Levels and Propionate Peaks

I’ve been running daily 20 mg Testosterone Propionate (IM) along with 150 IU HCG (IM) every day.

At first, I was getting a lot of energy — even a bit of anxiety sometimes — but lately that energy seems to have faded. I’m not sure if there’s some kind of downregulation happening or if something else is going on. Cognitively I also feel a bit less sharp, maybe some working-memory issues.

Anyway, what I really want to understand now is:
How high does DHT actually rise with daily Propionate injections?

I’ve read that Propionate peaks around 4–6 hours, while some sources (and ChatGPT) say closer to 14–18 hours post-injection. But did anyone ever measure DHT along with those Propionate pharmacokinetic studies?

I’m curious if DHT follows the same timeline — like, does it peak slightly later, and by how much does it rise compared to total T?

Would love to hear if anyone here has lab data or personal bloodwork showing DHT values with Propionate (daily or EOD), and how it tracked with energy or mood.

Thanks!

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.
