@SpiralusSancti
How much time do you have before you go in and get your blood drawn?
Basically taking AAS that are not Testosterone will shut you down and not come up in the test.
I'm not sure is any AAS will come up as Testosterone in a blood test, maybe
@CFC can help us out there?
I'm thinking Dianabol (AKA Metandienone) or NPP (Nandrolone Phenylpropionate) should massively lower your testosterone production given a week or 2 and at high enough dosages, but there is no way we can guarantee that you'll then quickly bounce back to normal production while you wait for your results and Test script.
It's highly likely that you will, and there's meds you can take to stimulate Test production, such as Gonadorellin, HCG and SERMs, but you'll be taking a bet.
Some people just don't come back to normal quickly, even though a very time limited exposure makes it very unlikely.
There would be no real liver or kidney toxicity risk involved in this and no cardiovascular damage risk, in fact the only consequence you'd risk would be long term reduction of your Testosterone production.
You could experience mood disturbances, difficulty sleeping, changes in appetite, acne, increase or decrease in libido, difficulty getting an erection or teenager style random erections and a few more things due to the quick hormonal changes you'd be causing, until you either recuperate your current production or you get on your Test script.
Other than these issues, you'd be breaking the law by buying steroids on the black market (not in all countries but in most), and running risks associated with buying non pharmaceutical quality drugs.
Not sure how the clinic/practice you will go to handles giving TRT scripts, but one test might not be enough for you to get one.
They might want you to make lifestyle and dietary changes and then get tested again in a few months, meaning you'd need to go through this more than once.
This is just a generical outline and I can elaborate further if you think you will go this route.
