PCT is very misunderstood. Working with endos in the hospital, I saw patients labs. Hundreds if not over a thousand of them.
I lost count.
It takes 2-12 months for HPTA to return. Age, health, metabolism, organ function, cycle history, etc, are all variables in how fast your natural levels will return.
As for Covid, there's so much unknown. We really don't know all the drugs and compounds that may interact with the virus.
You could easily wait until your major symptoms pass to start. Even if it's a week or more its' not going to hurt you to delay PCT.
And you really should be doing a longer PCT then 1-2 months.
My guys stay on Clomid at 25mgs for 3-4 months MINIMUM. We then take them off, give a few weeks and test labs to see if they are close to within range. If they are not, we resume Clomid use.
