Identity, composition and analytical documentation
Each released lot is tested by an independent laboratory (Horizon Analytical for the current lot). The certificate reports identity by mass spectrometry, purity by UPLC/MS, and net content measured against the labeled amount. A separate endotoxin report accompanies the certificate for this lot. The certificate does not include heavy-metal, sterility, residual-solvent or microbial testing. The lot number on the certificate is the lot number on the vial, so a certificate can be matched to the material in hand. Certificates for every lot released on this site remain available on the COA page.
Research overview
Findings below are from the cited laboratory and animal studies; nothing here describes effects in people.
Research Overview
Body Protection Compound 157 is a synthetic pentadecapeptide derived from a protein found in human gastric juice. It consists of 15 amino acids in a specific sequence that gives the peptide its characteristic stability in acidic environments — a property that has made it one of the most widely studied peptides in tissue repair and cytoprotective research.
Researchers investigate Body Protection Compound 157 for its interactions with multiple biological systems, including nitric oxide (NO) signaling, growth factor modulation, and angiogenesis pathways. Preclinical studies have examined its effects on endothelial cell proliferation, collagen deposition, and inflammatory mediator regulation in various tissue models. The peptide's proposed mechanisms involve FAK-paxillin pathway activation and VEGF expression modulation.
Body Protection Compound 157 is frequently studied alongside other recovery-focused peptides. Comparative research with TB (Thymosin-B) examines differences in actin-binding versus cytoprotective mechanisms, while comparisons with GHK explore complementary tissue remodeling pathways.
Body Protection Compound 157 vs TB: Complementary Tissue Repair Mechanisms
Body Protection Compound 157 and TB (Thymosin-B) are the two most studied peptides in tissue repair research, operating through fundamentally different mechanisms. Body Protection Compound 157 engages intracellular signaling — nitric oxide synthase, VEGF-mediated angiogenesis, and FAK-paxillin pathway activation — while TB acts through extracellular actin sequestration and cytoskeletal modulation. Because these pathways are non-overlapping, researchers frequently study both to map the full signaling landscape of tissue repair. The pre-mixed Wolverine Blend combines both for combination protocol research. See our Body Protection Compound 157 vs TB comparison for detailed analysis.
Laboratory applications include wound healing models, gastrointestinal mucosal studies, tendon and ligament cell culture assays, and neurotrophic signaling research. The peptide's gastric stability makes it a useful tool for studying oral bioavailability of peptide compounds. For sourcing guidance, see our Where to Buy Body Protection Compound 157 resource.

Frequently asked questions
- Which lot will I receive, and how do I check it?
- The lot shown on this page (DPS-9628420) is the one currently shipping; when a new lot is released, this page and the COA page update together. The lot number is printed on the vial label and matches the certificate.
- What does the certificate of analysis cover?
- Identity and purity by UPLC/MS from an independent laboratory (Horizon Analytical), measured net content against the labeled amount, and appearance, with a separate endotoxin report; both documents are linked above as PDFs. The certificate does not include heavy-metal, sterility, residual-solvent or microbial testing.
- What identifiers should match the certificate?
- The compound name, molecular formula and molecular weight in the compound information block are the values PubChem lists for this compound; the certificate reports identity by mass spectrometry against the same molecular weight.
- How should the vial be stored on receipt?
- Sealed lyophilised vials are kept cold, dry and away from light; long-term storage is frozen. The handling notes on this page and the storage guide give the laboratory practice in more detail.
- When does an order ship?
- Orders placed before the daily cutoff shown above ship the same business day from Austin, Texas, with tracking. Delivery estimates and the free-shipping threshold are shown in the order summary.
