Repair+ Stack (BPC-157 · TB-500 · KPV vials)
Three-vial repair kit: BPC-157, TB-500 and KPV supplied unmixed
- FormLyophilized powder in each vial, individually capped
- Research areasTendon and gastrointestinal models, cell migration, NF-κB inflammatory signalling
Overview
The Repair+ Stack supplies BPC-157, TB-500 and KPV as three individually sealed lyophilized vials. It covers the same three compounds as the co-formulated 30 mg blend, but leaves them unmixed, which is the decisive difference for any study that needs to vary one component against the others.
Two of the three are repair-model peptides. BPC-157 is a synthetic 15-residue sequence corresponding to a partial region of a protein found in human gastric juice, studied in rodent tendon, ligament and gastrointestinal models. TB-500 reproduces the actin-binding domain of thymosin beta-4 and appears throughout cell-migration research. The third, KPV, comes from a different direction entirely: it is the lysine-proline-valine tripeptide forming the C-terminus of alpha-melanocyte-stimulating hormone, and its literature concerns inflammatory signalling rather than structural repair.
Because KPV is by far the smallest molecule of the three — 342 g/mol against 1,420 for BPC-157 — molar equivalence and mass equivalence diverge sharply, and separate vials let a protocol choose which of the two to hold constant. Each vial carries its own lot number, HPLC assay at ≥99% purity and certificate of analysis. Sold for laboratory research only.

Working out the concentration
Reconstitution is where the arithmetic lives. The same vial made up with 1 mL or with 3 mL of diluent gives three-fold different numbers, which is why a reconstitution volume calculator is more use here than a fixed table: enter the vial mass and your diluent volume and read the concentration back.
Certificate of analysis
Every lot of Repair+ Stack (BPC-157 · TB-500 · KPV vials) is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Purity: ≥99% by HPLC per vial — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about Repair+ Stack (BPC-157 · TB-500 · KPV vials)
How does this differ from the BPC-157 + TB-500 + KPV blend?
The blend puts all three into one vial at a fixed 10/10/10 mg ratio. This kit keeps them in separate vials, so concentration, ratio and timing are decided by the researcher. Choose the blend for convenience, the kit for experimental control.
Are the vials tested separately?
Yes. Each is a distinct manufacturing lot released with its own certificate of analysis reporting HPLC identity and purity for that peptide. Three separate documents accompany the kit, and current lot COAs can be requested before you order.
Should any of the solutions be coloured?
No. This kit contains no copper complex, so all three peptides reconstitute to clear colourless solutions. Any tint, cloudiness or visible particulate is a reason to stop and set that vial aside rather than proceed with the preparation.
Why does KPV appear alongside two repair peptides?
Because it brings a different literature. BPC-157 and TB-500 are studied in tissue repair and cell migration; KPV, derived from alpha-MSH, is studied around inflammatory signalling and mucosal models. Together they cover repair and inflammatory arms in one panel.
Can one vial be used and the others stored?
Yes. Unopened lyophilized vials stored sealed at −20 °C and protected from light and moisture stay stable well beyond a year, so a protocol can work through the kit one component at a time as study phases require.
