Can testosterone "stop working" eg showing in blood results?

[gonzo6183]

Little background before my question gets written off...

I've been on trt 250mg a week for about 7 years now (prescribed) and have done cruise/blast during this time with a few blasts per year at 500-1000mg a week and occasionally adding other compounds.

The last time I had bloods done (on 750mg) a few years back my test came back at 220nmol/L (normal range 10-33nmol).

On my recent blasts results have diminished and I don't feel the test working, not even sex drive so got blood work done the other day for my current blast of 750mg/week with the following results:

Test: 28nmol/L
This is 1/8th of the results I had from the same dose I got tested at last time and explains a lot about how I feel and the results.

But my question is being pharma grade/prescribed test how is this even possible?

Can exogenous testosterone actually stop working/being taken up and utilised my the body?

What can I do?

I've had a few complete breaks even recently off completely for 3-4 months for a "rest".

At a complete loss and my doctor can't seem to explain it either.

Any help would be greatly appreciated.

When was the last cycle in regards to these symptoms? Maybe you are still suppressed.

Try to post this in the TRT sub forum, lots of smart people usually chime in

It's been the last 2 cycles including the current one. Have tried that section previously with other posts but not nearly as many people there to answer

I have to ask the basic question, is the current Test pharma grade? If it's from a UGL the advertised dose may be highly questionable.

That test doesn't give the same effects at the same dose (anabolic wise)
after long use, that's one thing.

But that it wouldn't be absorbed to the blood stream.. well...

ive heard it can be excreted a little faster, but just this is a disputed argument.
That it should change serum concentration by THAT much,
I think Scotchguards question seems the most plausible answer.

Even if supposed pharma grade, it can be fake.
I've bought fake gear in an Egyptian pharmacy.

Australian pharmacy on script, it's not fake or under dosed

That's 806 ng/dl it's clearly working. How long after your last pin did you run labs cause ya the number is low for the dose
