BPC-157 5mg Research Peptide Overview
BPC-157 5mg is a research-material designation referring to a nominal 5 mg quantity of BPC-157 intended for laboratory and scientific investigation. For researchers evaluating peptide materials, the quantity alone is only one part of the quality assessment. Chemical identity, sequence, molecular weight, analytical purity, HPLC results, mass-spectrometry data, and batch-specific documentation can all contribute to a more complete evaluation.
BPC-157 is commonly identified as a synthetic 15-amino-acid peptide. The current PubChem record identifies BPC-157 with the molecular formula C₆₂H₉₈N₁₆O₂₂, molecular weight 1419.5 g/mol, exact mass 1418.70415882 Da, and sequence GEPPPGKPADDAGLV.
For research documentation, the exact chemical form should also be verified. BPC-157 free base and BPC-157 salt forms are not interchangeable for molecular-weight calculations. PubChem, for example, lists BPC-157 TFA salt separately at 1647.6 g/mol.
This makes analytical transparency particularly important for a BPC-157 5mg product page.
What Is BPC-157?
BPC-157 is a 15-residue peptide that appears in biochemical and preclinical research literature under names including BPC-157 and BPC 157.
According to PubChem, its principal chemical identifiers include:
| Property | BPC-157 |
|---|---|
| Peptide length | 15 amino acids |
| Sequence | GEPPPGKPADDAGLV |
| Molecular formula | C₆₂H₉₈N₁₆O₂₂ |
| Molecular weight | 1419.5 g/mol |
| Exact mass | 1418.70415882 Da |
| CAS | 137525-51-0 |
| PubChem CID | 9941957 |
These identifiers provide a useful foundation for laboratory characterization.
A researcher’s evaluation should go beyond the compound name, however. The name “BPC-157” does not independently establish the identity, purity, quantity, or analytical quality of a particular batch.
That is where HPLC, LC-MS, COA documentation, and lot-specific testing become relevant.
BPC-157 5mg Molecular Weight
The molecular weight listed by PubChem for BPC-157 is 1419.5 g/mol. Its exact mass is 1418.70415882 Da.
These values are useful when reviewing analytical data or comparing a research material with established chemical-reference information.
BPC-157 Molecular Data
Molecular formula: C₆₂H₉₈N₁₆O₂₂
Molecular weight: 1419.5 g/mol
Exact mass: 1418.70415882 Da
Sequence: GEPPPGKPADDAGLV
Length: 15 amino acids
The molecular-weight value should be interpreted according to the chemical form being tested.
Why Chemical Form Matters
Researchers should not automatically apply the free-base molecular weight to every BPC-157 product.
For example, PubChem lists BPC-157 TFA salt as:
Molecular formula: C₆₆H₁₀₀F₆N₁₆O₂₆
Molecular weight: 1647.6 g/mol
The sequence is still represented as GEPPPGKPADDAGLV, but the salt components change the total molecular composition and molecular weight.
Therefore, a high-quality research page should identify the chemical form whenever analytical molecular-weight information is presented.
BPC-157 Peptide Sequence
The BPC-157 sequence is:
GEPPPGKPADDAGLV
It contains 15 amino-acid residues. PubChem provides the sequence as well as the corresponding condensed representation H-Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val-OH.
Why the Sequence Is Important
Sequence information is a fundamental component of peptide identity.
For analytical research, the sequence can be compared with:
- molecular formula;
- expected molecular weight;
- exact mass;
- LC-MS results;
- peptide characterization data;
- reference materials; and
- certificate-of-analysis information.
However, sequence information by itself does not prove that a particular batch contains only the intended peptide.
That requires appropriate analytical testing.
BPC-157 5mg Purity
BPC-157 purity is one of the most important supporting topics for this product page.
Researchers should distinguish between:
- nominal quantity;
- chromatographic purity;
- peptide content;
- molecular identity;
- related impurities;
- residual materials;
- microbiological testing where applicable; and
- batch documentation.
A product described as “high purity” should ideally have supporting analytical information rather than relying solely on marketing language.
What Does HPLC Purity Mean?
High-performance liquid chromatography, or HPLC, separates components of a sample according to their chromatographic behavior.
For peptide research, an HPLC result can provide information about the relative chromatographic profile of a material under the specified analytical conditions.
A reported HPLC percentage should not automatically be interpreted as proof of:
- molecular identity;
- absolute peptide content;
- sterility;
- endotoxin status;
- biological activity; or
- suitability for a specific experimental system.
These are different analytical questions.
BPC-157 HPLC Analysis
HPLC is commonly used as part of analytical characterization for peptide materials.
A useful BPC-157 HPLC report may identify:
Product
The tested material should be clearly identified.
Lot Number
A lot or batch number provides traceability.
Test Date
The date connects the analytical result to a particular testing event.
Analytical Method
The methodology should be identified where appropriate.
Purity Result
The report should provide the analytical purity result generated by the stated method.
Chromatogram
A chromatogram can provide additional visual information about the separation profile.
Laboratory
Where applicable, the testing laboratory should be identified.
This creates an important documentation chain:
BPC-157 → specific lot → analytical test → result → COA
For research environments where reproducibility and traceability matter, this is more useful than an unsupported generic purity statement.
BPC-157 LC-MS and Mass Spectrometry
LC-MS, or liquid chromatography–mass spectrometry, provides complementary information to HPLC.
HPLC primarily addresses chromatographic separation, while mass spectrometry can provide evidence related to molecular mass and chemical identity.
The PubChem exact mass for BPC-157 is 1418.70415882 Da.
When evaluating mass-spectrometry results, researchers should consider:
- charge state;
- ionization;
- adduct formation;
- salt form;
- instrument calibration;
- sample preparation;
- analytical method; and
- expected molecular species.
This is particularly important when comparing measured mass with a database value.
A measured LC-MS signal should be interpreted in the context of the complete analytical method rather than as an isolated number.
BPC-157 5mg Certificate of Analysis
A Certificate of Analysis (COA) is an important quality-documentation component for research peptide materials.
A useful BPC-157 5mg COA may include:
- Product name
- Product code
- Lot number
- Batch number
- Nominal quantity
- HPLC purity
- Identity testing
- LC-MS or MS data
- Testing date
- Analytical laboratory
- Analytical method
- Additional quality-control results
Why a Batch-Specific COA Matters
A generic specification tells a researcher what a product is intended to meet.
A batch-specific COA connects analytical results to a particular lot.
For example:
Product: BPC-157 5mg
Lot: Specific production lot
Test: HPLC / LC-MS
Result: Batch-specific analytical data
Date: Recorded test date
That traceability can be particularly valuable for laboratories documenting experimental materials.
BPC-157 Research Applications
BPC-157 has been studied extensively in preclinical research, with literature covering a range of biological and experimental contexts.
A 2025 systematic review of BPC-157 in orthopedic sports-medicine literature identified 36 included studies, of which 35 were preclinical and one was clinical. The authors emphasized that clinical safety data remained unavailable in their review.
More recent review literature similarly describes BPC-157 as scientifically interesting but notes substantial pharmaceutical-development and translational barriers.
For a research product page, appropriate laboratory-oriented categories can include:
- peptide characterization;
- analytical chemistry;
- HPLC method development;
- mass-spectrometry research;
- peptide stability studies;
- molecular research;
- biochemical experimentation; and
- comparative analytical testing.
These are research contexts and should not be converted into claims that BPC-157 is an established medical treatment.
BPC-157 Research Evidence: Preclinical vs. Clinical
One of the most important distinctions for accurate SEO content is the difference between preclinical evidence and clinical evidence.
BPC-157 has a substantial preclinical literature. Animal and laboratory studies have investigated biological effects across several experimental models.
However, the existence of preclinical findings does not establish a validated human therapeutic use.
The 2025 systematic review cited above found 35 preclinical studies and only one clinical study among the included literature. The authors specifically noted the absence of clinical safety data.
A 2026 review also reported that available clinical data remain very limited and that standardized pharmaceutical formulations and validated pharmacokinetic development have not been established.
Therefore, responsible content should use terms such as:
- “preclinical research”;
- “experimental research”;
- “laboratory investigation”; and
- “under investigation.”
It should avoid presenting experimental findings as established human outcomes.
BPC-157 and Current U.S. Regulatory Context
For a U.S.-targeted page, regulatory wording should be especially precise.
FDA’s current materials state that it has identified limited or insufficient clinical safety information for BPC-157 in the context of proposed compounded drug uses. FDA has also identified concerns related to immunogenicity and peptide-related impurities/API characterization.
A July 2026 FDA advisory-committee briefing specifically addressed BPC-157 free base and BPC-157 acetate in the context of proposed compounding uses. FDA’s briefing concluded that available clinical safety information was insufficient to characterize the safety profile for those substances.
Accordingly, a research-peptide product page should not describe BPC-157 as an FDA-approved medication.
It should also avoid suggesting that a “research use only” label automatically establishes legal or regulatory compliance for human use. FDA has recently emphasized that marketing intent and actual intended use matter when evaluating peptide products.
BPC-157 5mg Quality Evaluation Checklist
Researchers evaluating BPC-157 research material can use the following checklist.
1. Verify Identity
Confirm that the material is clearly identified as BPC-157.
2. Confirm Chemical Form
Determine whether documentation identifies the material as free base, acetate, TFA salt, or another form.
3. Verify Quantity
Confirm that the stated quantity is 5 mg and that the documentation corresponds to the relevant product.
4. Review HPLC
Look for a documented chromatographic purity result and, where available, the associated chromatogram.
5. Review Mass Spectrometry

Testing
Are HPLC and LC-MS results available?
COA
Is there batch-specific analytical documentation?
Traceability
Can the result be connected to a specific lot?
This framework supports a more transparent research-material evaluation.
