Guides
Two pieces written to be useful to someone who never buys anything from us. Both are methods rather than opinions, and both work on any product in this category.
Reading a quantified label — what to do when a label does publish every figure, which is rarer and more checkable than a blend.
Comparing two supplements — a method for putting two products side by side that does not depend on anything either one tells you about itself.
The two guides
Reading a quantified label
Most label guides teach you to work around a proprietary blend. This one is about the better case: what to do when the numbers are all there, and the four checks that take ninety seconds.
Comparing two supplements
Cost per studied dose, not cost per bottle. A method for putting two products side by side using only their panels and the literature.
Why these two
Almost every question a buyer asks reduces to two things: what is actually in this bottle, and how does it compare with the alternatives. The first is a label-reading skill and the second is a comparison method.
Neither guide argues for this product. Applied to this label, the first one produces the capsule count page, which is the least flattering document on this site. That is the test of whether a method is honest: it has to be allowed to reach an inconvenient answer.
| Guide | The question it answers | How long it takes |
|---|---|---|
| Reading a quantified label | What is physically in this capsule, once salts are converted? | About ninety seconds per label |
| Comparing two supplements | Which of these two delivers more of what I actually want, per dollar? | About five minutes |

The test of an honest method
It has to be allowed to reach an inconvenient answer. Applied here, the first guide produces a page saying it would take sixty capsules a day to reach one studied dose. We published it.
What the guides deliberately leave out
- Manufacturing quality
- Contamination, identity substitution and potency variance are real problems and none of them is visible from a label. A guide cannot teach a reader to detect them; only a test document can, which is the subject of the testing page.
- Whether any of it works at all
- The guides answer whether a product can deliver a studied dose. Whether that dose does anything useful is a separate question, answered by the literature on each ingredient.
- What you should take instead
- Not our place, and a seller's recommendation on that subject is worth nothing anyway. The comparison method is deliberately product-agnostic.
Keeping those out is what allows the guides to be short enough to use. A method that tried to settle everything would settle nothing in ninety seconds.
Three shorter pieces
Each post takes a single question further than a product page allows.
What a salt weight hides
Why 200 mg of an amino acid salt is not 200 mg of the amino acid, and how to do the conversion in two minutes.
Why grams, not milligrams
Some substances work at micrograms and some need grams. What decides which, and why amino acids are firmly in the second group.
The word “clinical”
One word on a label, two regulators, and what it commits a seller to under the FTC's own guidance.

See the VapoCept packs
Two, three or six bottles, priced plainly, with a 60-day window that runs from purchase. Read the capsule count first, then decide.
Shipping is calculated at checkout. This site publishes no figure it was not given.
A worked example, on this label
Rather than describe the first method twice, here it is run against the VapoCept panel with a stopwatch.
Seconds 0 to 5 — does the arithmetic close?
One capsule a serving, 30 servings, 30 capsules in the bottle. 1 × 30 = 30. It closes.
Seconds 5 to 20 — add the amounts
7.5 + 18 + 200 + 200 + 100 + 100 + 40 = 665.5 mg. Write it down. The front of a bottle never tells you this number.
Seconds 20 to 30 — names against substances
Seven names. Two are arginine, two are citrulline, so five substances. And no proprietary blend, which means everything that follows is possible.
Seconds 30 to 60 — convert the salts
AKG 2:1 is 70.5% arginine, citrulline HCl is 82.8% citrulline, the malate is 72.3% at its nominal ratio. 640 mg of amino acid entries becomes 536 mg of amino acid.
Seconds 60 to 90 — compare
Arginine 341 mg against a 3.32 g trial. Citrulline 155 mg against 2.4 g. Beta-alanine 40 mg against 2.4 g. Ten, sixteen and sixty capsules.
And the nutrients, separately
Niacin 7.5 mg NE against a 16 mg NE Daily Value is 47%, which is fine. Calcium 18 mg against 1,300 mg is 1.4%, which is not a nutritional contribution.
Ninety seconds, one division per substance, and no product page required. The capsule count page does the same thing at length and with citations, but the answer arrives in the first ninety seconds.
Using the guides on a competing product
A seller publishing a method that works against its own product invites an obvious question: what happens when you run it on the competition?
Usually one of two things. If the competitor uses a proprietary blend, the method stops at step one and you learn that the product cannot be assessed — which is itself worth knowing. If it quantifies its ingredients, you get a number you can put next to this one.
In this specific category the comparison is often unflattering to capsules generally, because the studied doses are in grams and gram doses are sold as powders. A buyer who works through the method frequently ends up looking at a tub rather than a bottle, and that is a legitimate outcome of an honest method.
We are not going to name competitors, run their numbers or publish a comparison table, because a seller's assessment of a rival is worth nothing and everybody knows it. Run the method yourself. It takes ninety seconds and the answer belongs to you rather than to us.

Who these are written for
Someone holding this bottle
The worked example above is your ninety seconds. Then read the capsule count page, which is the same method run to completion with citations.
Someone comparing two products
Run the label method on both, then the comparison method on the results. Cost per studied dose is the number that settles it.
Someone who will never buy anything from us
Take the method and go. That is a legitimate use of these pages and the reason they are written as methods rather than as arguments.
The third reader is the one that keeps these guides honest. A guide written only for a buyer quietly stops being a guide.
Corrections to the guides
A method with an error in it propagates that error into every label somebody runs it against, which makes these two pages the ones we would most want to be told about. If a step does not work or a conversion is wrong, write to the editorial inbox and name the step.
Where each method came from
Neither guide is original. Both assemble things that are already public into a sequence short enough to remember.
- The salt conversion is a ratio of molecular weights. NIST publishes the weights, PubChem publishes the stoichiometry of the 2:1 salt, and the arithmetic is one division.
- The label arithmetic check — serving size times servings equals the container — follows from the labelling rules themselves.
- The evidence hierarchy is the standard one used in any evidence review, compressed to seven rows.
- The instruction to use the lowest reported effective dose is ordinary best-case reasoning: if the most favourable comparison fails, the typical one does not need checking.
- The advice to establish a baseline before starting is from ordinary trial design, and it is the part most people skip.
Everything above is checkable, which is the property that matters. A method a reader cannot verify is an opinion wearing a numbered list.
The one piece of judgement in either guide is the instruction to check whether a trial measured the outcome you care about. That is not mechanical and it is where most of the mistakes in this category get made, including by people acting in good faith.
If you only remember one thing
Convert the salt, find the lowest studied dose, divide.
If the answer is that you would need ten servings a day, the product cannot deliver what the ingredient is known for, and no amount of ingredient count, seal artwork, delivery format or marketing language changes it.
That test takes two minutes, it requires no trust in any website, and it settles a large fraction of this market. Everything else on this site is a longer version of it.
What the guides deliberately do not cover
Neither guide tells you whether to take a supplement at all, and that is not modesty. It is that the question has a better answer elsewhere: sleep, hearing, blood pressure, exercise and a medication review all have larger evidence bases for cognition than anything in this category, and a seller is the worst possible source of advice on that comparison.
What these two methods do is stop a buyer from being misled about what is in a bottle. That is a smaller job and it is one we can do honestly.
Who made and checked this VapoCept page
Written from the seller’s panel, the front of the bottle and the sources cited on the page, then reviewed before publication. It is general information for adults and does not replace a conversation with your own clinician.
If your memory or concentration is changing, or you are on medicine for blood pressure or the heart, the first conversation is with your clinician, before the first VapoCept capsule.
