How long does testosterone drop after stopping

I have been taking 200mg of cypionate twice weekly for 12 weeks.
I am "supposed" to be take 200mg bi-weekly.
My doctor wants a blood test. How long after stopping the injections will my levels drop.
Should I do PCT or just slowly go back to bi-weekly?

There are plotters you can search for that will in theory tell when the cypionate is out of your system (3-4 weeks probably) but it may take longer for your actual blood levels to drop. If you are concerned about testing high I would test yourself through DiscountedLabs.com and then get your official test done when you are in the right range at which point you could resume biweekly (although some on here would argue that you should split the dose up to at least weekly) but that really depends on how you feel which will take time to determine. PCT only makes sense if you are coming off completely, so I'm not sure what you're asking there.

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.
