The label
Four entries, read one at a time
Three of the four are amino acids or amino-acid forms. The fourth is not, and it is the one entry this site cannot break down any further, because the product does not break it down either.
Entry one · amino acid
L-Arginine
Named first on the label. The product describes it as a direct building block for nitric oxide, which it in turn describes as a molecule that helps blood vessels relax. That description belongs to the product; see the note on how this site handles it below.
Entry two · amino-acid form
L-Arginine HCL
The same amino acid as entry one, presented as a hydrochloride salt. The product describes this form as more readily absorbed. It is still L-Arginine, in a different form, not a second and separate ingredient.
Entry three · amino-acid form
L-Citrulline DL-Malate
Described by the product as converting into L-Arginine once absorbed, which it frames as a slower, longer route to the same raw material as the first two entries.
Entry four · not an amino acid
Vasoactive Nitric Oxide Support Blend
Printed as a single line on the label, with no sub-ingredients listed anywhere this site could find. Unlike the first three entries, this one is not itemized, so nothing further can be said about what it contains.
What is missing, stated plainly
A milligram figure for any of the four entries. A Supplement Facts panel anywhere online. Neither is published in the product's material, and this site does not estimate either one to fill the gap.
Where the missing figures do exist
On the physical bottle. A Supplement Facts panel is printed there, on the label in hand, which is a different thing from a page on a website. Until a bottle is in front of you, those numbers are not available to check.
How the nitric-oxide account is handled here
Wherever this site repeats the product's explanation of how the four entries are meant to work together, it is captioned as the product's own account of itself — a claim the product makes, not a finding this site has verified or a result to expect. That caption is not decorative; it is the accurate description of what the explanation is.
Sixty capsules make up a bottle. At one capsule a day that is sixty days; at two, thirty. More on amounts and timing is on the dosage page, and the return terms if a bottle doesn't suit are on the returns page.
