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.
Suppliers hidden by the filters: 0. Suppliers shown: 4. Reset filters
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
TB-500 requires an identity check: an analytical study uses that name for an acetylated seven-amino-acid fragment, while full-length thymosin beta-4 has 43 amino acids. These are different substances.[1][2]
Identity checks
The studied TB-500 fragment is acetylated LKKTETQ, corresponding to thymosin beta-4 residues 17–23. Confirm sequence and modification instead of equating every TB-500 label with full-length thymosin beta-4.[1][2]
Identity and analytical evidence reviewed
The fragment paper describes detection in equine samples. A separate human eye-drop trial studied full-length thymosin beta-4. Analytical detection is not evidence of therapeutic benefit; findings for full-length ophthalmic thymosin beta-4 cannot validate a fragment sold under the same informal name.[1][3]
Regulatory context
FDA’s compounding safety entry concerns the LKKTETQ fragment, also called TB-500, and identifies a human-exposure evidence gap.[4]

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.
