How do we make money?
We link one company for money: Peptara Labs. When a purchase follows one of those links, we earn a commission. That's the whole commercial relationship.
We're a publisher. We don't stock anything we name, run a basket, set prices, take orders or sell anything. We're paid for a link you might follow, not for a sale, because we make none.
How is each kind of link marked?
Every link is marked for what it is, so you don't have to guess:
- A link to the company that pays us carries rel="nofollow sponsored noopener" and opens in a new tab. We mark it as paid whether or not that particular link earns anything, so paid and unpaid commercial links look the same to a crawler.
- The regulator's page and every public research record carry rel="noopener" only, and open in a new tab. Nobody pays us for those.
- Links within this site carry no rel marking. We never link to a sister site, or to any seller, marketplace, pharmacy, clinic or directory.
Commercial links only ever go to one of the two supplier pages we cite. We don't build links to certificate files by guessing; we link the certificates page, where the store publishes them.
What doesn't payment buy?
Payment buys the link, and nothing next to it. We didn't soften any state, move any mark, or write anything to order. Our one mark shows what the index printed on the day we read it. Payment didn't stop us recording that this compound's certificate was in testing on 2026-09-01. As of 2026-10-01 it is published, and we say that too.
If the paid relationship ended tomorrow, the mark would read the same. It comes from the index, not the invoice.
Which rule do we follow?
We follow the US Federal Trade Commission's endorsement guidance, written as questions and answers: the Federal Trade Commission's own endorsement guidance. Who we are, and how we assign and correct a state, is on who keeps this tray.
What does research use mean here?
We record the state of documents: what an index published on a given day, and what a research pack counts and leaves open. We make no claim about what any material does for anybody, and name no use for it.
Anything the supplier calls research grade, we treat as research material with no approved human use. Nothing here is medical advice or an instruction. We don't tell anyone to take or avoid anything.
Glutathione is research-grade material with no approved human use. Where another product on the same list has an approved label, it covers one indication in one defined group. It never shows a compound is approved, safe or reviewed for anything else.
About the supplier we name
Three questions people ask about the one company we link, answered from facts. You draw the conclusion. We score nothing.
Is Peptara Labs paid to appear on this site?
It's the other way round. We're paid a commission when a purchase follows one of our links to Peptara Labs. The payment buys the link, and nothing next to it.
Does payment from a purchase change what this site records about Peptara Labs?
No. We didn't soften any state or move any mark. Our one mark shows what the index printed on the day we read it.
What marking does a paid link to Peptara Labs carry?
Every commercial link carries rel="nofollow sponsored noopener", whether or not that link earns a commission.
