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: 2. 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
Full-length thymosin beta-4 is a 43-amino-acid peptide. Its chemical identity differs from the short fragment characterized as TB-500 in the cited analytical literature.[1][2]
Identity checks
Confirm that a source specifies full-length thymosin beta-4; a TB-500 nickname is insufficient. The human study cited here used a defined ophthalmic formulation.[1][2][3]
Human phase 2 study of an ophthalmic formulation
A randomized dry-eye trial enrolled 72 participants. Neither primary endpoint differed significantly at the specified final visit; some secondary endpoints favored the study formulation. These findings concern an eye-drop formulation and do not establish benefit or safety for research vials or other routes.[3]
Regulatory context
This review does not establish approval of a particular full-length thymosin beta-4 product. FDA’s separate TB-500 safety entry names a short fragment; it should not be treated as a full-length product assessment.[4][1]

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.

Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price, except that the labelled featured partner, LA Peptides, is pinned first; “Cheapest” always marks the lowest price.
