We're affiliated with Peptara Labs. If you follow a link from here to peptaralabs.io and place an order, Peptara Labs pays us a commission. Nothing else changes hands. It's also why the Peptara Labs line is the one whose pages we read.
Is Peptara Labs an actual supplier or just a website?
Links to Peptara Labs are affiliate links, and we may earn a commission when you buy through them.
Yes, there's a company behind it. Peptara Labs names itself as Peptara Labs LLC, registered in Wyoming, Filing ID 2026-002031026, at 30 N Gould St Ste 66115, Sheridan, WY 82801. That's on its trust page, which we read on 2026-09-01.
The same page calls it a newer platform. Whether that's enough is your call. We don't draw a conclusion. Peptara Labs' trust page
What doesn't the commission buy?
No box is written or changed for money. The sort is fixed and applies to the paying supplier like anyone else. Nobody is graded, and Not public is never used against anyone.
Does Peptara Labs give refunds if a vial does not match its certificate?
Yes, within 60 days of delivery, per its trust page (read 2026-09-01). If an outside laboratory's result disagrees with the certificate, or the order went wrong, you get a full refund. The supplier frames it around quality and says it covers no health outcome. the trust page at Peptara Labs
How are paid links marked?
Every link to peptaralabs.io carries rel nofollow sponsored noopener. One sentence saying links to Peptara Labs are affiliate links sits in every page footer, and just above the first such link on each page that has one.
The one link to the Federal Trade Commission carries rel noopener only, because it pays nothing. There are no other outbound links on the site.
What guidance do we follow?
We follow the Federal Trade Commission's endorsement guidance: the FTC's questions and answers on endorsements. See also the sheet the commission sits behind and the fixed sort key.
Which lab does Peptara Labs send its batches to?
Peptara Labs names Titreon Analytical as its testing laboratory. It describes Titreon as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited.
It also publishes four endotoxin reports from Janoshik, a second laboratory, each with a verification key. It says you can check the key at janoshik.com/verify. We haven't tested that. the Peptara Labs certificate page
