What's sold here, and who decides the evidence?
Material here is sold and labelled as lab stock. No prescriber or pharmacy stands in front of it. What evidence sits beside a batch is the seller's choice, not a regulator's rule.
You're the only checker in this lane. So the useful question isn't who vouched for the seller. It's which document opens without an account, and what it actually measures.
What record can this lane produce?
Our one worked example is the published certificate record. The supplier says its batches are tested by Titreon Analytical, a third-party lab whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited.
A certificate there shows identity by HPLC retention-time matching and by LC-MS, purity by HPLC against a release criterion of not less than 95.0 percent, net peptide content, sterility, bacterial endotoxin, a heavy metals panel and a fentanyl immunoassay screen. Across the published batches, arsenic, cadmium, chromium, mercury and lead each returned Not Detected.
Measured purity across the published catalog falls between 98.6 and 99.6 percent. Certificates are published on the certificates page, and a few items, such as Epithalon and Glutathione, show as Pending, meaning in testing. The full shape of the record is on what a per-batch record contains.
Who is the supplier?
The supplier behind that record is Peptara Labs LLC, registered in the United States, in Wyoming, under Filing ID 2026-002031026, at 30 N Gould St Ste 66115, Sheridan, WY 82801. It calls itself a newer platform on the supplier's entity and testing statement.
It operates as a strategic partner of Sheer Skincare International Corporation, registered in the Philippines. That partner holds a Philippine FDA License to Operate as a cosmetic trader, LTO-3000014576518, and a Philippine SEC certificate of incorporation, Reg. No. 2024120182028-11.
Both registrations belong to the partner, not Peptara Labs, and neither approves any product. A License to Operate like this is a facility licence for a cosmetic trader. It doesn't mean the FDA has evaluated any product for safety or effectiveness.
What does the paperwork promise?
The same statement offers a 60 day money back guarantee. The 60 days run from delivery. In that window a vial may go to an outside lab, and you get a full refund if it doesn't test as its certificate states, or if the order was mishandled.
The guarantee is about the quality of the document and the material, never a health outcome, which keeps it within what this lane can promise. The supplier also calls itself a seller of research-grade compounds and educational material, not a medical provider. It doesn't prescribe or supervise anyone's care, and says what it sells isn't a medicine any regulator has signed off.
Why cite this supplier but not list it?
We cite the supplier for its record and testing method, but list no row for it in this lane. Its own catalog file, read on 2026-09-01, says its tirzepatide is discontinued and not being restocked, with ordering ending August 31, 2026. That date has passed.
A discontinued item isn't a route. So we give no buying path to it for this compound, and point every mention to the certificate record instead. The second signature on one measurement of that record is on the second signature. The filed rows are on the home page, back to the lane table.
What do we cover?
We report two things and no third: which lane a route belongs to, and what paperwork it can produce. Material in the research supply lane is lab stock, not a licensed medicine. The supplier we cite says on its own pages that it sells research-grade material, not a medicine any regulator has signed off.
We don't assess any person or call anything safe or effective. Questions about a person belong with a licensed clinician.
