Four days after last test prop pin. Still have hard on and can masturbate.

39 yo
6'2. 205lbs
9 week test prop cycle 50 mgs Ed.
Week 9 started igf lr3 40mcg pwo, mgf peg 200mcg on weekends.
PCT 50/50/50/50 CLOMID, 20/20/20/20 NOLV.
Continue peps until post pct.

This is my first test cycle... I lost so much fat and transformed my body from overweight fatty to ripped and big. Gained maybe 5 lbs but the mirror transformation starting week 2 was insane and only got better.

I'm currently on day 4 after my last pin. Last night I took my clomid and Nolvadex. Hoping today wouldn't be depressing and painful. I woke up energized and with a hard on. This afternoon I even jerked it just to see if I could.
What do you think is happening. Genuinely curious. I know it's test prop because it started working day 2-3.
Maybe it's just weak as it expired 1 year ago. But my transformation says otherwise.

You're forearms are gonna get jacked with super wrist strength - it's important you control the masturbation. Think of it like playing a violin symphony using a feather from a virgin red-breasted swallow. Delicate but precise.

Did someone brainwash you into thinking you're wiener would fall off during PCT or something ?
