What's the story here? How much onion did he eat?

>>141682

I am not inclined to believe that interpretation of the hormonal measurements outright. "Free testosterone" is a meme, and I have heard testosterone will actually enter cells more often when attached to a protein. I'm assuming that is a measurement of serum 17-beta oestradiol, and my concern is that his tissues have taken up that estrogen and that is why there is less in his blood. I have heard that prolactin is a good correlate of tissue estrogen. Here's a couple references that highlight the possibility that he's made a mistake:

Benassayag, C., et al. Potentiation of estradiol binding to human tissue proteins by unsaturated nonesterified fatty acids. Endocrinology 118.1 (1986): 1-7.

https://doi.org/10.1210/endo-118-1-1

>Unsaturated NEFAs induced a 2- to 10-fold increase (P less than 0.001) in E2 binding to cytosol from normal, fibromatous, and neoplastic uteri, while saturated NEFAs had a slight inhibitory effect (P less than 0.05).

Bruning, P. F., and J. M. G. Bonfrer. Possible relevance of steroid availability and breast cancer. Annals of the New York Academy of Sciences 538.1 (1988): 257-268.

https://doi.org/10.1111/j.1749-6632.1988.tb48870.x

>We demonstrated that sex steroid protein binding is decreased by free fatty acids.

Nonesterified fatty acids = free fatty acids. So in other words it is possible that his SHBG has decreased due to an increase in free fatty acids, and such an increase in free fatty acids is likely to cause his estrogen to attach to tissues more frequently rather than make its way out of the body. Serum measurements of hormones are potentially very misleading. Sometimes observing the physiological state of the body provides a more accurate picture of the direction it is taking. This means I find it likely that he could have taken before and after pictures of his face and body and a change in bloat or water retention would more accurately reflect a change in physiologically important estrogen levels than "divining his blood".

I took a quick scan of onion and related topics research. I'm far from making conclusions, but I found a couple items that are fuel for skepticism for now. (Everything is fuel for skepticism.)

Alrefaie, Zienab A., Hanan A. Amin, and Sabah H. Elgayed. Estrogenicity of outer scales of onion on uteri of immature mice. Canadian journal of physiology and pharmacology 89.11 (2011): 829-835.

>This estrogenic activity could be attributed to the quercetin and daidzein content, and activation of estrogenic receptors, as these effects disappeared after blockage of E2 receptors. Our results support the possible estrogenic properties of the onion extract, which could be attributed to quercetin and daidzein, but not that of garlic extract.

van der Woude, Hester, et al. The stimulation of cell proliferation by quercetin is mediated by the estrogen receptor. Molecular nutrition & food research 49.8 (2005): 763-771.

https://doi.org/10.1002/mnfr.200500036

I caution against setting conclusions in stone. I saw many papers that seem on the surface to attribute many seemingly positive qualities to both onions and its commonly studied flavonoid, quercetin. However, onions are a whole food containing many compounds with quercetin being only one whose nature is not adequately characterized in my opinion. I don't think studies which measure narrow parameters instead of taking in the whole physiological result get to the heart of the matter but that doesn't stop people from running with the first answer they find. It's always important to ask why things happen, and the absence of mechanistic explanations or the parroting of lazy ideas is often a clue that promoters of substance or food haven't fully assessed what it does.

Maca root powder really works.

But pair it with some L-theanine so you aren't bouncing off the walls.

I've currently got some fish oil, biotin, calcium/magnesium/iron, vitamin C, melatonin, allegra allergy, and a general multivitamin. I feel like an old man when I have to swallow 6 fucking pills. They seem to be doing me well at this time. I did however buy the female kind of biotin, so I don't know what the consequences will be.

Will report back findings. Whey, creatine, and fiber powders are all pluses of course. That fancy chemical compound stuff is a little too much for me, personally. Both in price, and strength.

Shrek is all the proof I need.

If you ate enough red meat in a day those supplements you listed wouldn't do anything.

Good point, at least in chicken breast there are amounts of those amino acids close to the daily dosage recommendations. That doesn't mean that having more of that amino acid would hurt, or that the dosage recommendation alone is enough though.

1 raw onion a day, or maybe two, can't recall exactly. Another relevant detail is that the guy used to be a professional bodybuilder who competed and roided, but long ago.

Listen effortfag, you're using literature references wrong, you don't just vomit them into fulltext hoping someone reads through all your shit. You make a statement or quote something, then provide a direct reference to that statement in case the reader wants to verify the claim or get additional information. The references should be numbered and grouped beneath the text, in a footnote.

>Creatine has been shown to increase ATP retention in muscles by X%[1], which in turn increases muscle performance[2].

>…

>[1] URL to some study that shows this

>[2] another study or literature

If you had ever finished your bachelor's degree, you would know this.

Works in what way, what does it do?

>>141725

Im currently taking a multivitamin, 1-2g of vitamin C powder after training, one 5000IU vitamin D pill, and 5g of creatine each day. I find it practically impossible to really measure the effects of the exact components on yourself, except for maybe vitamin D.

Partaking in activities that one enjoys does not call for effort, but—lol—are you for real? I enjoy questioning these topics for myself because I enjoy learning instead of licking up every bit of bullshit broscience vomited on my screen. I then write it out to help myself solidify the knowledge and post it here because it's fun to see what response I'll get and it doesn't matter if I don't get one because all I did was copy/paste. If they get butthurt, it's hilarious sticking it in everyone's noses to contradict them time and time again. If they get interested, it's fun watching someone else learn, or if it helps them, that would make me happy.

I don't consider myself a troll, but your response dictates whether you will be harassed, helped, or something else, and I'm more than content to follow along with whatever direction you take it. Looks like you're wanting to get your jimmies rustled over my writing style. Good choice. Let's see how that goes. But I do sometimes use citations when the posts get much longer than that. If you don't have time to read titles and quotes that immediately follow the relevant paragraph, oh well.
