BPC-157 & TB-500 Blend
The BPC-157 & TB-500 Blend is a pre-filled research pen containing both compounds — the gastric-derived pentadecapeptide BPC-157 and the thymosin β4 fragment TB-500 — in a single lot-tracked format, 40 mg total. It exists for laboratories that evaluate the two compounds together and want a pre-measured, no-reconstitution presentation. Each component is tested to ≥99% by HPLC/MS and the batch COA reports both. Research use only.

What is in the blend?
Two compounds, each with its own research literature: BPC-157, studied in tendon, ligament and gut-lining models [1][2], and TB-500, a thymosin β4 fragment studied in actin-regulation and cell-migration models [3]. Neither is altered by being combined; the blend is a convenience format, not a new molecule.
Why researchers pair them
The two peptides appear in overlapping areas of the recovery-model literature but through different studied pathways — one gastric-derived, one an actin-binding fragment. Laboratories comparing or combining them can use the pen to hold the ratio constant across a series. For the mechanism-level comparison see BPC-157 vs TB-500; for the format decision see vial vs pen.
Specifications, purity and documentation
Identity and purity are tested per component by HPLC/MS. The COA lists both. Store refrigerated and away from light; keep capped between uses. How to read the COA →

- BPC-157 vs TB-500: What the Research Actually Compares — The two most-requested recovery-category peptides are structurally unrelated and studied through different pathways. Here is the side-by-side, with sources.
- Lyophilized Vial vs Pre-Filled Pen: Choosing a Research Format — Nine catalog compounds ship as vials, five as pens. The choice is about flexibility versus consistency, not quality.
- Multi-Peptide Research Blends Explained — A blend is not a new molecule. It is two or more compounds held at a fixed ratio so a series can vary one thing at a time.
