The Thehorsefuel blog
The Thehorsefuel blog covers the questions the order desk hears most, at more length than a product page allows: why a microgram is not a milligram, what a supplement’s name is allowed to imply, and why this site publishes no star rating. Written and reviewed by the Horse Fuel Editorial Desk.

The three posts, in more detail
Micrograms are not milligrams
The most useful post here if you are comparing supplements at all. It explains the three weight units on a Supplement Facts panel, why the step from mg to mcg is a factor of a thousand and one letter wide, what a 10:1 extract ratio lets you work backwards to, and three physical comparisons to keep in your head. It ends on our own product, because the arithmetic applies there too.
What a supplement name is allowed to say
About the element that does the most persuading and carries the least accountability. Claims are regulated; brand names are trademarks. The post explains why the rules stop where they do, what a medical prefix imports in four letters, and what happens when a brand moves its persuasion from words into icons that nobody has to substantiate. It uses our own product as the worked example — a case that passes the name test and then fails a step later, when the claims turn out to be made in pictures rather than words.
Why this site publishes no star rating
The decision behind our reviews page, written up because the reasoning generalises. It covers why ratings do unusually heavy lifting in supplements, the five ways supplement reviews go wrong, the five conditions a rating has to meet before it means anything, and what we publish in its place.
How these posts are written
Every quote is from a source we opened
Memorial Sloan Kettering, NCCIH and the FDA. If we could not open it, it is not quoted.
No invented studies
No reference numbers we did not check, no "a 2019 study found" without a link.
Posts may argue against the product
All three of these do, in places. That stays in.
A visible last-updated date
Equal to the dateModified in the page's structured data.

Why read a seller's blog sceptically
Including this one. Most supplement blogs exist to occupy search results for questions buyers ask on the way to a purchase, and the articles are written backwards from the answer the seller wants.
So here is the test we would apply to any of them. Does the post ever reach a conclusion that costs the seller money? Does it quote sources you can open? Does it name a specific weakness in the product being sold, rather than only in other people's products?
On this blog: the first post ends by showing that our own four botanicals weigh 0.4 mg between them, the second uses our own packaging as its example of persuasion moving into pictures, and the third explains why the most persuasive element on a product page is missing from ours. Those are the passages to weigh when deciding how much of the rest to trust.
Product pages, if that is what you came for
| If you want | Read |
|---|---|
| What is in the bottle | Ingredients |
| What the label shows | Label facts |
| Whether it suits you | Who it is for |
| Safety and interactions | Side effects |
| Packs and value | Pricing |
| Category background | Guides |
Four ideas that run through all three posts
The unit is the finding
Nearly every result in supplement research is a result about an amount. A label that names an ingredient without a unit you have read carefully has shown you the research and withheld the part that makes it mean anything.
Transparency and adequacy are different questions
An itemised panel is more honest than a proprietary blend. What it then reveals may be worse. Both things can be true and it is worth holding them apart.
Persuasion moves to wherever it is least accountable
Claims are regulated. Names are trademarks. Icons are graphics. Push on one and the work migrates to the next, and the last one carries no obligation at all.
Absence is information
No other-ingredients list, no allergen statement, no standardisation, no return window, no verified reviews. Five absences tell you more about a product's paperwork than any claim on its front.
All four are uncomfortable for the product this site sells, which is why they appear here rather than only in the pages nobody reads.
What we will not publish here
A short list, so the shape of this blog is clear from its edges as well as its contents.
- No “natural ways to boost testosterone” post. It would collect readers with a symptom worth investigating and send them to a bottle instead of a blood test.
- No ranked list of competing products. We sell one of them; a ranking published by a seller is an advertisement with a table in it.
- No single-ingredient enthusiasm piece. That genre is how this category talks itself into claims the research does not carry.
- No invented case studies. No composite customers, no illustrative journeys, no “Leon K., 54, Phoenix AZ” — which is, as it happens, exactly what was in the review pack we declined to publish.
- No before-and-after photographs. There is nothing to measure and nothing was measured.
If one of those is what you came for, the honest answer is that a clinician will serve you better than an article, and that the articles promising otherwise are written to rank rather than to help.
How these three posts fit together
They were written in the order they appear, and each one came out of a question the previous one left open. Read end to end they make a single argument about where to look on a package and in what order.
Start with the unit
The first post is about micrograms, milligrams and grams, and about what a 10:1 extract ratio lets you work backwards to. It is the most mechanical of the three and the most immediately useful, because reading the unit before the number takes five seconds and changes what you see.
Then ask where the persuasion is
The second post is about names, claims and icons — the elements that do the convincing and the wildly different obligations attached to each. It ends somewhere we did not expect: with a product whose name is clean and whose front label carries no sentence at all.
Then decide what to trust
The third post is about ratings: why they carry so much weight in a category where nothing can be evaluated at the point of sale, the five conditions one would have to meet before it meant anything, and what this site publishes in place of one.
None of the three requires you to trust this desk about anything. Every quotation is linked to a page you can open, and every calculation is one you can repeat on a phone.
Corrections and updates
Every post here carries a last-updated date, and it is the same date that appears in the page’s structured data. When a source revises its position, the post changes and the date moves; we do not leave a quotation in place because it was accurate in 2026.
Corrections go to the site desk and are acted on before anything else in the queue. If a quotation here does not match the page it claims to come from, that is the most serious kind of error this blog can make, and we want to hear about it the same day rather than at some later point when the mistake has been quietly repeated elsewhere.
Who writes these posts
The Horse Fuel Editorial Desk, an internal team, writes them, and Dr. Jonathan Clavell, MD, a physician, reviews each one before it is published. There is no invented author, no stock photograph of a clinician and no fabricated credential attached to anything here, because a byline nobody can verify is worth less than a citation everybody can open.
Each post is built the same way: read the label photographs, open every source, do the arithmetic against a published reference table, and write down what survived. Where a figure could not be verified the post says so rather than reaching for a weaker source. Where a finding runs against the product this site sells, it stays in.
That is the entire method, and it is deliberately unimpressive. The value of these posts is not expertise; it is that every step in them is one you could have taken yourself, and that where we took a step you can check it.
Read the label, then the blog
Both are on this site, and neither is trying to hurry you.
