What Is BPC-157?

There has been a lot of excitement around BPC-157 over the last couple of years, particularly among Laboratory Researchers, Sports Science Professionals, Researchers in Regenerative Medicine and Peptide Analytical Experts. Examples of this growing interest include search terms such as; ‘What is BPC-157?’, ‘BPC-157 Research Peptide UK‘, ‘BPC-157 Certificate of Analysis’ and ‘Where to buy BPC-157 Research Grade UK’ reflecting the growing demand for evidence-based information regarding peptides.

This guide follows an evidence-first approach for the presentation of the content. The information includes a Definition of BPC-157, a Mechanism of Action of BPC-157 both in Experimental Models and Published Scientific Publications, how UK Researchers typically acquire Scientific Analytical Quality BPC-157, and how to validate Product Quality from Batch Specific Laboratory Documents.

BPC-157 is an acronym for Body Protection Compound 157. BPC-157 is made up of 15 amino acids and it is a synthetic peptide. During gastrointestinal peptide research conducted in Croatia, scientists discovered BPC-157 as a naturally occurring protective agent of the stomach. While the BPC-157 used in laboratories today is produced using peptide synthesis, it was originally derived from an isolated biological source.

At the present time, researchers are examining BPC-157 for applications in:

• Experimental models of tissue regeneration
• Research on how soft tissues recover from injury
• Studies looking at repairing tendons and ligaments after injury
• Experimental models of vascular regeneration
• Protecting the gastric mucosa
• Pathways of cellular migration
• Mechanisms to support neuromuscular recovery

In the UK, BPC-157 is generally only available in the scientific community for research/analytical purposes.

Instead of working through one isolated mechanism, researchers believe BPC-157 might simultaneously influence, for example, vascular signalling pathways, inflammatory pathways, cellular migration, and tissue remodelling.

Angiogenesis and Microvascular Repair

One of the most commonly encountered mechanisms is angiogenesis, or the biological development of new blood vessels.

The formation of healthy vascular structures is critical to healing tissue; in order for the tissue to regenerate, blood vessels must supply it with:

• Oxygen
• Nutrients
• Growth factors
• Immune cells

Preclinical studies demonstrated BPC-157 may have an effect on three primary pathways related to angiogenesis:

• VEGF signalling pathways
• Activation of VEGFR2
• Akt signalling pathway
• Regulation of eNOS

Preclinical tendon and/or muscle injury models indicated an increase in the amount of vascular density following treatment with BPC-157.

Nitric Oxide Pathway Regulation

BPC-157 may also have an effect on nitric oxide (NO) signaling.

Nitric oxide has a significant role in:

• Regulation of blood flow
• Maintenance of endothelial structure
• Delivery of oxygen to the tissue
• Promotion of an inflammatory balance
• Communication between cells

Currently available in an animal model, BPC-157 may facilitate the recovery of endothelial cells through the modulation of nitric oxide; however, there is no human confirmation at this time.

Fibroblast Movement and Collagen Remodelling

Fibroblasts are cells that manufacture structural proteins, like collagen.

Preclinical studies suggest that BPC-157 may influence:

• Fibroblast movement from one area to another
• Aligning collagen
• Reorganizing the extracellular matrix
• Fusing tendons to bones
• Remodelling ligaments

This is why BPC-157 is frequently found in orthopaedic and musculoskeletal studies.

Anti-Inflammatory Signalling

Chronic inflammation can delay healing of tissue.

BPC-157 may affect:

• Cytokines
• Inflammation
• Oxidative stress
• Recovery processes for cells

The effects of BPC-157 on humans are still being evaluated.

Cytoprotection of the Gastrointestinal Tract

Research began on BPC-157 with the goal of establishing a protective mechanism.

Animal studies were conducted to assess:

• Gastric ulcers
• Intestinal inflammation
• The rebuilding of mucous membranes
• The restoration of intestinal barriers

These studies are some of the earliest and most thorough analyses of BPC-157.

What Does Current Research Show?

Current BPC-157 research has expanded rapidly in the last ten years. Current research primarily focuses on the effects of BPC-157 on the following areas:

• Musculoskeletal repair
• Tendon regeneration
• Ligament repair
• Gastrointestinal healing
• Nerve recovery models
• Vascular repair

Most of the current published evidence has come from:

• animal studies
• cell culture studies
• preclinical biological models

There is little evidence available on human subjects.

Musculoskeletal Research

Current studies show that tendon and ligament studies offer the strongest evidence in regards to BPC-157’s efficacy. Animal studies suggest that BPC-157 may:

• Increase the tendon loading capacity
• Improve collagen organization
• Enhance mechanical stability
• Decrease inflammatory marker levels
• Increase the rate of structural recovery

BPC-157 has produced some interesting initial findings in animal studies studying rotator cuff injuries, Achilles tendon models, and disruption of ligaments. As with any animal-based research, these findings may or may not hold true when applied to human clinical studies.

Neurological Research

Like many of the research areas studied with BPC-157, new studies on the neurological system are also emerging. Currently, the following effects have been noted:

• Enhanced peripheral nerve recovery
• Improved neuromuscular signalling
• Enhanced spinal cord recovery
• Protective action on the neurovasculature

Again, this area is still in the early phases of research and no conclusive evidence has been found using human subjects.

Gastrointestinal Research

Current preclinical gastrointestinal research has explored the following potential effects:

• Restoration of gastric mucosa
• Decreased formation of gastric ulcers
• Support of the intestinal barrier
• Recovery of the inflammatory bowel

These experiences were amongst the earliest pieces of scientific evidence that generated interest in BPC-157.

What Is Currently Lacking in Human Clinical Evidence?

Scientific caution must apply here.

At this time:

• There is a limitation on human clinical trials
• Very small participant numbers have been published
• No large randomized controlled trials are available
• No trials involving long-term safety have been completed

Therefore, due to the current limitations in human evidence, BPC-157 should not be described as:
• Clinically validated
• Therapeutically established
• Medically approved

There is currently insufficient clinical evidence to support statements such as ‘guaranteed healing,’ ‘clinically valid recovery,’ and ‘proven injury repair.’

Is BPC-157 Legal to Purchase in the UK?

BPC-157 is not an officially recognized medicine by the MHRA in the UK and therefore does not have a license as such.

What this means is:

• BPC-157 cannot be sold legally in the UK, as a treatment or cure for any medical condition.
• All products claiming therapeutic effects must hold regulatory approvals to sell those products
• Suppliers of BPC-157 may label their product simply for ‘laboratory use only’

While all suppliers of BPC-157 may list the information above, it is important to ensure compliance from suppliers before making a purchase.

Where to Get BPC-157 in the UK

When sourcing BPC-157 you should do more than simply select the lowest cost supplier.

A responsible research supplier should demonstrate clear batch traceability, analytical verification and transparent documentation.

Batch Traceability

Each vial should have:

• A batch number
• A date of manufacture
• An expiry date
• Storage conditions required
• Peptide concentration

The absence of any of these points is a reliable sign of an unreliable supplier.

Independent Laboratory Testing

Responsibly operated suppliers will carry out independent 3rd party testing for:

• HPLC purity
• LC-MS identity confirmation
• Microbial contamination
• Residual solvents
• Endotoxin screening

Without analytical testing it is impossible to determine whether a product is what it purports to be.

Research Documentation

Suppliers who provide detailed documentation regarding their laboratory testing of their products include:

• Downloadable lab reports
• Documentation supporting your product batch
• Transparency of all testing methodologies as applied to the tested products
• Connections between testing dates and your products batch

Generic laboratory reports should be considered with caution.

How to Verify a BPC-157 COA

A COA or Certificate of analysis verifies that a product has been tested and gives you the information about how to read a COA and how to source peptides.

Step 1: Confirm Compound Identity

The BPC-157 COA must include:

• Molecular weight
• Amino acid sequence.
• LC-MS Confirmation of Results.

If the values do not match, then there is a problem with the sample.

Step 2: Determine HPLC Purity

The HPLC Purity will be used by the research lab for acceptance, but they prefer ≥98% purity. If the purity is lower, then the integrity of the compound may have been compromised due to incomplete synthesis, storage conditions, or the manufacturer being inconsistent with their finished product. Purity is only one indicator; it is a vital one.

Step 3: Verify Batch Numbers

The COA will include:

• Lot number
• Batch ID
• The date the batch was manufactured.
• When the Batch will be tested.

If the numbers do not match the BPC-157 you received, then it means that the COA does not apply to your product.

Step 4: Verify Laboratory Credentials

The COA must identify the laboratory that performed the test, what method of testing was used, and must be signed or have a stamp showing validation from the testing laboratory. If the COA is missing any of, the information reflects that the report should not be trusted.

Step 5: Verify Proper Storage Conditions

Peptides are sensitive compounds and can lose their stability. Proper storage information should always be included on the COA, such as:

• The proper temperature for storage.
• If the product is light sensitive or requires protection from light.
• The proper procedure for reconstituting the peptide.
• Storage stability of the reconstituted peptide.

If BPC-157 is not stored correctly, the integrity of the product may be compromised.

Red Flags When Sourcing BPC-157 for Research

Researchers should steer clear of suppliers who:

• Claim to cure any disease
• Will not allow a supplier to produce lab test results
• Will not disclose batch number
• Provides poor quality COA documents
• Market their products through influencers and not science
• Provide unreasonably priced products

Transparency is much more important than product branding.

Safety Issues

There are no clear long-term human trials conducted with BPC-157, thus no evidence for the long-term safety of this peptide; currently there is insufficient information on BPC-157 in relation to the following questions:

• How does it affect the vascular system in the long-term?
• Does it have an effect on cancer biology?
• What are the outcomes of chronic use?
• What are the risks of interaction with other drugs?
• Will there be any cardiovascular implications of use?

Until better human evidence becomes available on the effects of BPC-157, it should only be used in a controlled research setting.
