Filter suppliers by testing, delivery and payment
Filters hide suppliers; the order is always by price. Testing counts the core test categories printed on each supplier’s newest certificate for this exact product. A count is not a quality rating, and vendor claims such as “8x tested” are not used. Destinations and payment methods are those recorded on each supplier’s profile.
What the filters mean
The core 7 are identity, purity, net content, endotoxin, sterility, heavy metals, multi-vial conformity. Identity counts once whether it is shown by mass spectrometry or by HPLC retention time. Sterility counts for a 14-day USP <71> culture or a rapid PCR sterility test, which are labelled apart. Microbial-limit counts and bioburden are not sterility tests. Multi-vial conformity means two or more vials or bottles from one lot measured on the certificate.
Vendors describe batches as “6x”, “7x” or “8x tested” to mean the number of assays on one batch report, and they count differently. Those labels are not used here; only the categories printed on the certificate count.
A supplier without a product-specific certificate is hidden by any testing filter, and so is a certificate that does not state which package size it covers when the supplier sells several. Certificates are vendor documents read by PeptideTech on Oct 7, 2026; the samples are not independently authenticated.
Ships to and payment method use the destinations and methods each supplier publishes, as recorded on its PeptideTech profile. A supplier whose shipping or payment coverage is not recorded is hidden by that filter rather than assumed to qualify. Confirm both at checkout. In stock only hides offers that were out of stock or stale when last checked.

Selected sources reviewed
Retatrutide, also identified as LY3437943, is an investigational agonist at GIP, GLP-1 and glucagon receptors. A peer-reviewed phase 2 trial and a later sponsor-described phase 3 program are different levels of source evidence.[1][2]
Identity checks
“Triple agonist” names the three receptor targets; it does not identify a separate “GLP-3” receptor or authenticate a product sold under that nickname.[1][2]
Published phase 2 evidence; phase 3 sponsor updates
The published randomized phase 2 trial enrolled 338 adults. Lilly’s current information describes an investigational phase 3 development program. Sponsor updates are identified as sponsor information, not substituted for a peer-reviewed paper or regulatory approval.[1][2]
Regulatory context
Drugs@FDA lists no NDA, BLA or ANDA with retatrutide as an active ingredient (names searched: RETATRUTIDE, LY3437943; checked October 7, 2026). Research-labelled Retatrutide listings are not FDA-approved drugs.
Sources: Drugs@FDA active-ingredient search: RETATRUTIDE, LY3437943 · checked
FDA states that retatrutide is not a component of an FDA-approved drug. Lilly describes it as investigational. This review does not infer regulatory status for every country.[3][2]

Research searches — not supporting citations
Search results may include unrelated records. A search link does not establish that a matching study exists.
These selected sources describe named substances and studied formulations. They do not authenticate a supplier, a certificate of analysis or the contents of a particular lot, and do not provide instructions for use. “Healing” and other catalogue categories are navigation labels, not evidence of efficacy or treatment recommendations.
