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
The thymosin beta-4 17–23 fragment is a seven-amino-acid region. The TB-500 material characterized in the cited analytical paper is its N-acetylated form, acetyl-LKKTETQ.[1]
Identity checks
A fragment is not full-length, 43-amino-acid thymosin beta-4. Verify whether a listing specifies the same sequence and acetylation as the cited material.[1][2]
Analytical study; human evidence gap
The reviewed study identified and measured the fragment in equine doping-control research. It was not a human treatment trial. FDA reports that it has not identified human-exposure data for this fragment in its compounding assessment.[1][3]
Regulatory context
The FDA compounding safety assessment specifically names the LKKTETQ fragment. It does not establish product approval or import permission.[3]
