BPC-157, Thymosin beta-4 (TB-500), and related peptides studied for soft-tissue repair, wound healing, and recovery from connective-tissue injury.
Research peptides in this class act on the shared machinery of wound healing rather than on a single receptor: angiogenesis, fibroblast and keratinocyte migration, extracellular-matrix turnover, and resolution of local inflammation. The evidence base is overwhelmingly preclinical, built on rodent models of tendon, ligament, muscle and gastrointestinal injury, and the thinness of the human literature is the central fact about the category.
Two compounds anchor the category: BPC-157, a synthetic fragment of a protein found in human gastric juice, and thymosin beta-4, the actin-binding peptide vendors sell as TB-500.
Vendors stock BPC-157 and TB-500 side by side and sell them as a fixed pair, which obscures that they share no sequence, no origin and no mechanism. BPC-157 is a gastric-protein fragment acting largely on angiogenic and nitric-oxide signaling, whereas thymosin beta-4 is a cytoskeletal regulator. The pairing is purely a market convention.
The naming around thymosin beta-4 is itself a source of confusion. "TB-500" was originally the code for a seven-residue fragment of thymosin beta-4 carrying the actin-binding motif, but the label migrated to the full-length peptide as vendors moved to the full chain. PeptideScouter indexes the full-length peptide under TB-500 and thymosin beta-4 and keeps the short TB-500 Frag 17-23 as a separate row, because a per-milligram price on one is not comparable to the other.
Nothing in this category is an FDA-approved drug, and the July 2026 news did not change that. What moved was compounding access. On April 15, 2026 the FDA announced the removal of twelve peptides from Category 2 of its Section 503A bulk drug substances list, the bucket for substances raising significant safety concerns, effective seven days later. BPC-157 and TB-500 were both on that list.
The Pharmacy Compounding Advisory Committee then voted to recommend adding both to the 503A bulks list, though on the TB-500 side the substance FDA reviewed was the short fragment, not the full chain. It voted the same way on KPV, catalogued under Immune and Anti-inflammatory.
Two qualifiers carry most of the weight. The vote is advisory and does not bind the FDA, which changes the list only through notice-and-comment rulemaking. And it ran against the agency's own scientific review staff, whose briefing documents recommended against adding all seven substances on the agenda, partly on the grounds that several are not characterized well enough to assess. Research-grade material sold by the vendors indexed here is not a compounded prescription and is labeled for laboratory use only.
In October 2026 HHS issued a policy under which it does not intend to take enforcement action against pharmacies compounding BPC-157 or the TB-500 fragment under set conditions until a final rule settles each listing, and our post on the HHS policy covers its terms.
Three multi-peptide blends carry trade names consistent enough across sellers to work as a decoder:
Some vendors append the combined milligram load to the name, so "GLOW-70" and "KLOW-80" are the same formulas at a stated total strength. Vendors also sell the BPC-157 plus TB-500 plus KPV tri-blend without the copper component, or BPC-157 plus KPV alone.
Pentadeca Arginate, sold as PDA, is described by vendors as the BPC-157 sequence supplied as an arginate salt. The published research is on BPC-157 itself rather than on the arginate salt as a distinct entity, and PeptideScouter carries no CAS number for it.
ARA-290, also called cibinetide, is a synthetic peptide modeled on part of erythropoietin's surface and studied for tissue-protective effects in animal models of nerve, kidney and wound injury.
GHK, glycyl-histidyl-lysine, is a copper-binding tripeptide present in human plasma and studied for extracellular-matrix remodeling. The copper-chelated form GHK-Cu is catalogued under Skin and Cosmetic.
B7-33 is a single-chain analog of the relaxin-2 B-chain studied in rodent models of heart and lung fibrosis.
These three trade names are used consistently enough across vendors to act as a decoder. Wolverine is BPC-157 plus TB-500. GLOW is GHK-Cu plus BPC-157 plus TB-500. KLOW is GHK-Cu plus BPC-157 plus TB-500 plus KPV, which is GLOW with the anti-inflammatory tripeptide added. Some vendors append the combined milligram load to the name, so GLOW-70 and KLOW-80 are the same formulas sold at a stated total strength rather than different products.
Not always. Vendors sell both the full peptide and a short fragment as TB-500, and the name did not start out that way. TB-500 was originally the code for a seven-residue fragment of thymosin beta-4, residues 17 to 23, which carries the actin-binding motif. As vendors moved to selling the full 43-amino-acid peptide, the TB-500 label came with them. PeptideScouter indexes the full-length peptide and the short 17-23 fragment as separate rows, because they are different molecules and a per-milligram price on one tells you nothing about the other. The CAS number or molecular formula on a certificate of analysis is the only reliable way to tell which one a listing is selling.
No. On July 23, 2026 the FDA Pharmacy Compounding Advisory Committee voted to recommend adding BPC-157 and TB-500 to the Section 503A bulk drug substances list. That vote is advisory only. It does not make either compound an FDA-approved drug, and it does not by itself authorize compounding: the FDA changes the bulks list through notice-and-comment rulemaking and is not bound by the committee.
Vendors describe Pentadeca Arginate as the same 15-amino-acid sequence as BPC-157 supplied as an arginate salt, and market that form as more stable. The published research is on BPC-157 itself rather than on the arginate salt as a separately characterized entity. PeptideScouter carries no CAS number for it, and it is indexed as its own row so its pricing does not get mixed into BPC-157 pricing.
47 vendors tracked by PeptideScouter sell Healing & Repair peptides, across 500 listings covering 12 compounds. The widest Healing & Repair catalogs belong to EZ Peptides (9 peptides), ION Peptide (9 peptides), Disguised Alpha (8 peptides). Prices are normalized to USD per milligram and refreshed daily.
Healing & Repair peptides indexed on PeptideScouter have a median price of $4.66/mg, ranging from $0.55/mg to $9.70/mg across the 12 peptides in the category. Pricing is normalized across vendors and refreshed daily.
GHK carries the lowest median price in the Healing & Repair category at $0.55/mg across 1 listing. Its cheapest in-stock listing is $0.55/mg at Optima Chemical Supply. Per-milligram price varies widely between compounds in a category, so the cheapest per mg is not necessarily the cheapest vial or the right compound for a given experiment.
The most widely sold Healing & Repair peptides on PeptideScouter (by vendor count) are: BPC-157, Wolverine Blend, TB-500 Thymosin Beta-4, GLOW Blend, KLOW Blend. Each peptide page shows current pricing across every tracked vendor, normalized to USD per milligram.
