Thanks for the shoutout. I’m continuing to summarize published research and evidence-based stories on testosterone on my blog https://tparty.org/. My last post was on Semen Retention for increasing T, which I will be replicating with others.

In terms of the supplements not doing anything, it may be just be the brand, as I talked to another person who used the same brand and also didn’t see increases in T. Apparently Amazon supps suck!

Interesting Re: the supps efficacy

Thanks for the comment!

After >year of weightlifting and >1/2 year of carnivore diet my T is "abnormally high": 30.4 nmol/l = 877 ng/dl. But I see you managed to get it even higher, so I'm quite interested how.

How old are you? Ultimately I think it is pretty personal to the individual and their baseline.

I'm much more inclined to believe in someone like Bryan Johnson who is as transparent as it gets over David Sinclair who is trying to sell books/pills/companies. Really nice observation about the vegetable oil rather than the meat itself as a possible cause for an upset stomach. I personally like to use avocado oil to fry food, it's neutral tasting with high-quality fats and has a very high smoke point.

As smart and well credentialed as some of these researchers are, I think they could all read some Nassim Taleb and admit that we don't understand how complex of a system the human body is. They can find all sorts of associations but that does not imply causation. It's very upsetting that even scientists with PhD's will go out of their way to make stuff up to promote/defend their ideas. I think it's human instinct and very difficult to overcome. I was reminded of this tendency just a while ago when my wife texted me one of her vegan friends lamenting that movie theater popcorn is loaded with butter. Then her other vegan friend texted back with "most movie theaters use coconut oil to cook popcorn". Literally just trying to justify their behavior so that it was not inconsistent with their strongly held beliefs rather than admitting they love the taste of butter. These same vegan friends are also eating some of the most heavily processed food and snacking on things loaded with sugar throughout the day to stave off hunger while admitting to having certain nutrient deficiencies. All for the sake of a misguided belief that their behavior is somehow better for the planet (a huge thank you for all the great content you've posted on this topic).

The world would be so much better off if people could just be okay with eating whatever tastes good to them instead of thinking they need to prove to others they are correct. I personally have been almost exclusively on animal products for the past few months and feel amazing. Pretty sure you can get all the nutrients the body needs regardless of the source but as Bryan Johnson has said in his videos he eats 70lbs of vegetables per month, which is impractical for most people. Like you mentioned with spinach iron having only a 2% absorption rate, the bioavailability for plant source nutrients is just a lot lower.

Exactly! Proper long term studies are impossible anyway, so rather than focusing on the length of my life I focus on current health.

I'm also a carnivore for more than 1/2 of a year and felt amazing for a while, then got some rare deficiencies which I'm addressing and already feel better.

Very much looking forward to you reading and looking into David Sinclair's Lifespan. Would love to read/watch a deep dive from you into NMN, whether it is all it's cracked up to be and worth taking, especially since it can be expensive.

Again it is just so frustrating to see how poorly done most nutrition science is with how it constantly contradicts itself. Which I get, it's complicated and the body is complicated but to have people like Sinclair and Rhonda Patrick promote vegetables and such but then have other dismiss it and promote something like carnivore it just gets more and more difficult to assess what is good and what isn't. What is being promoted through a desire to make money and be famous and what is someone just trying to promote what they feel is right?

I think what can be agreed though is current food guidelines are terrible and we're in the worst generation for overall human health. So something has to change.

For example, just the length alone of the human digestive tract has been found to be on average around 8m, with a variability of ±1.3m.

https://pubmed.ncbi.nlm.nih.gov/12497219/

Meaning the shortest one was almost 30% shorter than the longest one. But, short or long, I would expect the easily digestible carnivore diet to be superior as long as you listen to your body and don't just check off some list.

I’ve stumbled upon Dr.Sinclair’s work before although I believe his work has substance to it the evidence is just not supplemented to be grounded in realism. Every person has a different parameters for resveratol.

The mention of the dye being the active ingredient rather than reservitol reminds me of the promising effects of Methylene Blue. Originally a dye, it penetrates cells super well for staining (why it's such a good dye) and seems to help mitochondria health tremendously.

When you mentioned spinach's iron absorption of 2%, that reminded me of the age old theory my dad used to say of how "calcium and iron compete for absorption", and thus, should not be taken together.

Would be cool if there's an article or video debunking (or approving) this.

Also, this is my first time commenting on your blog post, i just gotta say, thanks a lot for all the information you provide; it's by far the most accurate I've seen. Most of the information other articles/videos provide seems quite misleading and it's hard to trust what's accurate and what's not these days.

In relation to your second point it would be interesting to know if those Chinese programmer motivators paid off or if they ended up being mere distractions. Sadly, the only available data points appears to be in the form of American outrage.
