Body Protection Compound-157
Also known as: BPC 157, Pentadecapeptide BPC 157, Bepecin

Updated 2026-03-18
BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It has generated extraordinary interest for its broad cytoprotective and regenerative effects observed in preclinical studies across virtually every organ system studied. Despite this promise, it remains one of the most controversial peptides due to the near-complete absence of human clinical trial data.
Class
Tissue Repair & Regeneration
Routes
Subcutaneous, Oral, Intramuscular
Half-Life
<30 minutes (estimated from animal studies)
BPC-157 is proposed to activate the FAK-paxillin pathway, modulate nitric oxide (NO) synthesis, upregulate growth factor expression (VEGF, EGF), and interact with the dopaminergic and serotonergic systems. It appears to promote angiogenesis, reduce inflammation through multiple pathways, and accelerate wound healing. The exact molecular targets remain incompletely characterized.
Half-Life
<30 minutes (estimated from animal studies)
Bioavailability
Not established in humans. Animal data suggests rapid absorption via subcutaneous and oral routes.
No approved human indications. Preclinical research areas: gastrointestinal healing, tendon/ligament repair, muscle injury recovery, neuroprotection, liver protection, cardiac protection.
A 2025 systematic review identified 36 total studies: 35 conducted entirely in animals, and only one human study — a retrospective case series of 12 individuals with knee pain and no control group. No randomized controlled trials exist. Animal data is remarkably consistent in showing regenerative effects across tissues, but translation to human outcomes is completely unvalidated.
Human Studies
1
Animal Studies
35
No human safety data from controlled studies. Animal studies report minimal adverse effects at studied doses. Key concerns: unknown immunogenicity in humans, potential for contamination in unregulated products, unknown long-term effects, potential interaction with angiogenic pathways relevant to cancer progression (theoretical). WADA temporarily banned BPC-157 in 2022.
FDA Category 2 (September 2023) — cannot be compounded for human use. Not FDA-approved for any indication. Products sold online as "research chemicals" carry no guarantee of purity, dosing accuracy, or safety. DEA: not a scheduled substance. RFK Jr./HHS have publicly discussed potential reclassification (February 2026), but no formal regulatory action has been taken.
Recent Regulatory Activity
Drug Interactions: Theoretical — BPC-157 may influence NO pathways and blood flow; caution with anticoagulants. No clinical interaction data exists. Research Gaps: The gulf between preclinical promise and clinical evidence is the defining feature of BPC-157. No standardized dosing, no validated safety profile, no human efficacy data from controlled trials.

Important Note
IMPORTANT: BPC-157 is not FDA-approved and cannot be legally compounded. These dosing ranges are from preclinical research and clinical anecdotes only — not validated in human trials.

Tissue Repair & Regeneration
TB-500 is a synthetic version of thymosin beta-4, a naturally occurring 43-amino acid protein fragment that plays critical roles in tissue repair, cell migration, and anti-inflammatory processes. Combined with BPC-157, it forms what is colloquially known as "the Wolverine stack" in regenerative wellness circles. Like BPC-157, its clinical evidence base is limited to preclinical data.
Tissue Repair / Anti-Aging
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Levels decline significantly with age (from ~200 ng/mL at age 20 to ~80 ng/mL at age 60). It has gained attention for its broad biological activities including wound healing, anti-inflammatory effects, collagen synthesis, and potential gene expression modulation.
