I never said his hair formula is the best. Although, if you can point to some specific thing in his hair formula that is bad I'm all ears. As far as I can tell, it's a pretty solid formulation especially considering that first and foremost, hair is not his primary concern.
Yes that is the primary thing. However, it's like saying minoxidil (being the best thing for regrowth we have at the moment) 2% is just as good as minoxidil 5%. We know it isn't. If you're comfortable leaving potential results on the table by not caring about stuff like SHBG, I'm not stopping you. Just don't pretend like you're doing all you can be, because you aren't. All I'm trying to say is to go as far as you have, but chicken out by looking at things through a very narrow lens of "Low T, High E = hair" is kind of a deluded half measure that leaves a lot of potential benefits on the table for no good reason. The good thing about the Powers method is that even if it doesn't work, it doesn't hurt you either. Literally nothing to lose except the potential gains and a VERY miniscule amount of money that boron costs you and the slight inconvenience of dosing twice as frequently as you currently do.
How is it nonsense? If you are blocking all of your androgen receptors in your body, it shouldn't matter what your testosterone level is because it can't do anything in your body due to bica blocking all of its potential receptor sites. The only way you wouldn't experience menopause symptoms is if a significant amount of T aromatizes into E as a result of your bica usage (which at that point, again what is the point of bica monotherapy? Are you starting to see why he recommends against it yet? I don't know how much clearer it can be made for you). I don't really know how you're coming to the conclusion that blocking all the ARs in your body with bica is any different than nuking T entirely through something like CPA.
You know what menopause is, right? And that it causes decreased bone density? It shouldn't matter whether or not your T is nuked from something like CPA, or just rendered useless from something like Bica. Either way, if you are not supplementing with E you will run into the issue of not having any sex hormones, resulting in menopause symptoms. I feel like I'm going on like a broken record at this point but the only way Bica in a sufficient dose to block all ARs through monotherapy wouldn't cause this is through aromatase into E. If you're already aromatizing E, you're still going to feminize. Additionally, with the doses required for this (200-300mg) you are talking about a much higher incidence of liver problems. Why would anyone ever choose to use bica mono only to end up still feminizing (with worse results than if supplemental E was used) while also putting their general health at risk? There's very little benefit to it and a lot of risk. Hence Dr Powers recommending against it. This isn't rocket science.
