Too soon to test?

Hey guys,

I restarted TRT after a break of a few months due to circumstances. My protocol was a weekly injection. The break was a cold-turkey stop. During that time my levels tanked to TT 140 / FT 8.5 / E 12.

I've been back on since August but the only value I got back from testing was TT at 693. My previous tests on treatment normally came back a little higher than this and with E values around 8.

My doctor was open to upping my dosage which I now split into a bi-weekly injection schedule. It has been a bit over 4 weeks and I am wondering:

Is it too soon to test at this higher dose?

I know relying on previous values is not ideal, so I'm eager to get bloodwork to see where I am. My doctor told me to test the day before my next injection due to my bi-weekly dosing schedule. I plan on testing through discountedlabs from now on to ensure that at a minimum my TT, FT, and E values are tested. With the added benefit of directly receiving my labwork, I'm eager to get going.

Initially .5 cc dose weekly shot.
Now .75 cc dose which I split into a bi-weekly shot.

My eagerness to test is due to the 50% increase in my dose.
Also, I have HCG on the way so I'd like to test before I introduce that variable into my protocol.

You have indicated a volume, not a dose. Dosage is expressed in milligrams. Are you injecting testosterone at 200mg/ml? Four weeks will give you a sound number to review.
 
I get labs on my injection day, but before I inject. I think you should wait at least six week before getting new labs after starting a new protocol.

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.
