Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
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.

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.
