10mg boron daily has been shown to lower shbg as well as Stinging Nettle, divanil specifically though I wouldn't use nettle and any 5AR blocker at the same time. Boron is fine to add anytime.
Joe. Boron can't not decrease SHBG , since boron lowers 2 enzymes. one CYP24A1 remember the one , which breaks down active vitamin D into inactive.
and also boron decreases hydroxylase which breaks down estrogen, and thus it raises estrogen and SHBG goes up.
Thus running boron solo in most cases will INCREASE SHBG since it will increase your calcium and estrogen.
This is why when you take magnesium , in a situation with either strong cortisol or HIGH cortisol which stops calcium intestinal absorption.
Body in those cases asks for boron and it always goes down on hairtest when you take magnesium., to kill vitamin D destruction and to kill estrogen destruction. So you can get some calcium. but this calcium comes from the bone.
Thus in high cortisol states, when you take magnesium , you get screwed with calcium since you lose it from the bone.
High cortisol or too strong cortisol, stops calcium intestional absorbtion, by killing potassium.
and if people in that condition take magnesium. they get huge calcium losses from teeth and bone. Since magnesium asks for more calcium , but calcium is not there. since cortisol is stopping the absorption of calcium from the intestine.
This is why I had a friend with bone cancer, who had huge problems with calcium absorption and utilization.
And he had a huge hole in his bone due to cancer. He tried all of this stuff , K2 , magnesium calcium. boron etc. and all of that stuff was making him worse.
but the minute I gave him potassium, the bone filled in right away. Since potassium allowed calcium to get absorbed from the intestine. his high cortisol was lowering potassium, and thus not allowing calcium to get absorbed. and if you increased magnesium then boom , you lower ventilation and PH goes down, this allows calcium into blood. Body increases boron, which increases estradiol which increases active vitamin D
This is why if people take potassium. boron goes up on the hairtest, since it is needed less. Boron is the thing that stops D1.25 break down, and stop estrogen breakdown. and therefore increasing both levels of estro and active vitamin D.
So for people who want more estro , boron is cool, and as I mentioned, some folks could get cured with estrogen.
I am not saying the case with high cortisol is your case of Jack17 case. in Jack17 case it is not. since he is a slow oxidizer probably with low cortisol levels.
This is just to show the regulations of boron, and what it does.
Here is the explanations of what i was saying so you can read it.

Of course I could assume, may be a snap back when you end taking boron is different. I don't know that.
it would be nice if you tested yourself finally with the hairtest and blood to see what case you are.
PFS is not the same for everyone so advising some people what works for you sometimes can cause major problems for the others as we clearly saw this on propecia forum. Good example soy, one case- out of PFS, another case in PFS.
