Description
What Is BPC-157 + TB-500? (In Plain English)
This listing is two different repair-research peptides packed together as one kit. BPC-157 is a short chain copied from a protein found in stomach juice, while TB-500 comes from a protein that helps cells build and move their internal scaffolding. Researchers pair them in animal studies to see whether two different repair signals add up to more than either one on its own.
BPC-157 + TB-500 — Research Overview
The stack combines two separately characterized compounds. BPC-157 is a synthetic pentadecapeptide (GEPPPGKPADDAGLV) derived from Body Protection Compound in gastric juice, and the literature associates it with VEGFR2–Akt–eNOS signaling and the nitric oxide system in rodent soft tissue and gastrointestinal models. TB-500 is supplied as a synthetic form of thymosin beta-4 or its active N-terminal region, and is studied primarily through G-actin sequestering, actin polymerization dynamics, and cell migration in vitro; combining the two is a common preclinical design because the associated pathways are distinct.
Primary Research Areas
- Combination study design — investigated in rodent models comparing single-compound and paired arms
- Soft tissue repair models — studied in tendon, ligament, and muscle injury preparations in animals
- Cell migration and actin dynamics — the primary in vitro research area for the TB-500 component
- Angiogenesis — examined for VEGFR2-associated vessel formation attributed to the BPC-157 component
- Gastrointestinal mucosal models — a long-standing rodent research area for BPC-157
Specifications

- Storage: Store lyophilized vials cold and protected from light. Reconstituted material is stored refrigerated per standard laboratory practice.
Related Research Peptides
Each component of this stack is also sold on its own, which is what laboratories choose when a study design needs one compound isolated: BPC-157 and TB-500. Researchers comparing presentations also look at BPC/TB Blend 20mg and KPV 10mg.
Why Researchers Source BPC-157 + TB-500 from Dissolv Labs
Dissolv Labs is a research-supply company based in Southern California. Orders are picked, packed, and shipped domestically from our SoCal facility, so most U.S. laboratories see short transit times and no international customs delay.
Every vial ships as a complete kit. Each BPC-157 + TB-500 vial is paired with its own bacteriostatic water reconstitution vial, so the material arrives ready to prepare in the lab without a separate diluent order. Compounds are supplied lyophilized in sealed, labeled vials with lot identification, and analytical documentation is available on request.
BPC-157 + TB-500 — Frequently Asked Questions
What is BPC-157 + TB-500 used for?
BPC-157 + TB-500 is supplied strictly as a research chemical stack for in vitro and laboratory research applications. The literature studies the two compounds in rodent soft tissue and gastrointestinal repair models, both separately and in paired designs. It is not for human or veterinary use.
How does this combo stack differ from BPC/TB Blend 20mg?
This listing supplies the two compounds as a stack so each can be prepared independently, which suits designs that vary one component at a time. BPC/TB Blend 20mg is listed as a combined presentation instead. Check the fill weights stated on each listing before ordering, since they differ.
How does the BPC-157 + TB-500 kit ship?
Both compounds ship lyophilized in sealed, lot-labeled vials, packed together with bacteriostatic water for reconstitution. Vials are kept cold and shielded from light until prepared. Laboratories running larger preparation volumes often add BAC Water 10ml to the order.
Where can I buy the BPC-157 + TB-500 stack?
Dissolv Labs supplies the BPC-157 + TB-500 combo stack to qualified laboratories from our Southern California facility. Orders ship domestically as a complete kit with reconstitution vials and lot identification for each component. Analytical documentation is available on request.
Research Use Only
BPC-157 + TB-500 is sold exclusively as a Research Use Only (RUO) chemical. It is not a drug, supplement, cosmetic, or food, and it is not intended for human or veterinary use, ingestion, injection, topical application, or any form of consumption. It is intended solely for licensed laboratory research by qualified professionals. Dissolv Labs makes no medical, therapeutic, or diagnostic claims of any kind. By purchasing, the buyer confirms they are a qualified researcher and accepts full responsibility for lawful handling, use, and disposal.
Bacteriostatic (BAC) water is included free with every order.

Exact quantity and concentration are listed in the product title and variant options above. The figures above are release specifications — the measured result for your particular lot is stated on its Certificate of Analysis.
Documentation & Testing
Every batch is tested before release. Testing covers four checks: identity by mass spectrometry, purity by HPLC against a ≥99% release threshold, content verification against the labelled mass, and batch release tied to a specific lot number.
To request the Certificate of Analysis for your vial, email us with your order number or the lot number printed on the label. We do not gate documentation behind a form or a purchase.

Handling & Storage
Lyophilized peptides are relatively stable during transit. Arriving at room temperature is not cause for concern — the cold pack is a margin of safety rather than a pass/fail condition.
Sealed vials of lyophilized material are typically stored refrigerated or frozen and protected from light. Handling protocols for a specific compound are determined by the researcher and their institution; we supply the material and its documentation.
Shipping & Returns
Orders placed before the daily cut-off are dispatched the same business day from Southern California in insulated packaging with ice packs. Tracking is issued at dispatch.
If a shipment arrives damaged, if vial contents appear inconsistent with the specification, or if the lot number on your vial does not match the certificate we provide, contact us and we will resolve it.
Because these are temperature-sensitive laboratory materials, opened vials cannot be returned to stock.
