BPC-157

BPC-157 is a synthetic peptide made up of 15 amino acid units, sometimes referenced in laboratory literature under alternate designations such as PL 14736. It is referenced in laboratory research on tissue repair and is not approved by any drug regulator for human or animal use.

BPC-157 is a synthetic peptide - a short chain of amino acids - made up of 15 amino acid units. In laboratory literature it is sometimes referenced under alternate designations, including PL 14736, though naming varies by source. It belongs to a broader class of peptides referenced in laboratory research on tissue repair. It is not sold here as a drug, supplement, or finished consumable product, and it is not approved by any drug regulator for use in people or animals.

Quick facts

• Structure: a synthetic peptide built from 15 amino acid units, not a naturally occurring hormone.
• Alternate names: sometimes listed in literature as PL 14736; conventions vary by source and study.
• Category: referenced in laboratory literature on tissue-repair research.
• Regulatory status: not approved by any drug regulator for human or animal use.
• Form supplied: lyophilized (freeze-dried) research material intended strictly for laboratory reconstitution workflows.
• Scope of this page: identity reference and reconstitution-hardware notes only - not dosing, protocol, or usage guidance.

All of our reusable peptide pens (V1, V2, V3 and Gansulin) are compared on one page.

BPC-157 is typically supplied to researchers in lyophilized form inside a standard 3 ml glass cartridge and reconstituted before use in laboratory workflows. Cartridge and pen compatibility questions come up often, so here is what we can confirm from our own specifications.

Cartridge and pen compatibility

• Our reusable pens accept universal 28G to 33G screw-on pen needles.
• Our pens take standard 3 ml (300-unit) glass cartridges with the 11 mm long plunger (stopper), the cartridge we sell. 3 ml cartridges are also made with a shorter, about 8 mm plunger, and a pen is built for one height, so check that a cartridge from another source has the 11 mm long plunger before loading it; the glass looks identical from the outside.
• We can only speak to our own hardware specifications above; we have not tested compatibility with pens or cartridges from other manufacturers, so we cannot confirm fit with third-party equipment.

Always check stopper length and cartridge diameter against your specific pen before assembly, and handle all materials strictly within a research setting.

What it is

BPC-157, short for Body Protection Compound 157, is a synthetic (lab-made) peptide referenced in laboratory research. A peptide is a short chain of amino acids — the small building blocks that link together to form larger proteins. BPC-157's chain contains exactly 15 amino acids, making it a comparatively small research peptide.

Its published sequence is modeled on a partial fragment of a protein found in human gastric (stomach) juice. Despite that biological reference point, BPC-157 as supplied is produced entirely through laboratory peptide synthesis — it is not extracted, purified, or derived from animal or human tissue.

Like most research peptides, BPC-157 is typically supplied as a lyophilized (freeze-dried) powder sealed in a glass vial or cartridge. This form keeps it stable for storage and transit, but it must be reconstituted with an appropriate diluent before laboratory use — a workflow step covered later in this article.

Research context and categorization

BPC-157 is categorized within the healing and tissue-repair class of research peptides used in laboratory settings. This classification is used for organizing research literature, not as a statement of approved use.

Published research has examined it in laboratory models involving:

• Wounds, tendons, ligaments, muscles, and bones
• Gut injury and bowel inflammation
• New blood vessel formation (angiogenesis)
• Cell protection in internal organs

Key point: Nearly all BPC-157 research has been conducted in animals, not people. Reported findings are not confirmed or approved.

• Most research comes from animal studies, primarily in small rodents
• A limited number of research groups account for much of this work
• Human data remains very limited

These research applications are investigational — still under study and not proven. Reported findings are not confirmed or approved outcomes in people, and nothing here should be read as an established benefit.

Status

• Regulatory status: Research-only. BPC-157 is not approved by the FDA, or by any other drug regulator, for any use in people, and it is not a recognized dietary ingredient. Regulators have flagged it as an unapproved drug substance with unresolved safety and characterization questions.
• Sport status: Prohibited under the WADA Prohibited List, the global anti-doping rulebook for sport. BPC-157 sits under class S0 (Non-Approved Substances) and is banned at all times, both in and out of competition; it is also classed as a Specified Substance. Anti-doping bodies have stated that a Therapeutic Use Exemption (a special medical permit) would not be granted for it, and athletes have been sanctioned over products containing it.

Reconstitution notes (general)

Lyophilized (freeze-dried) peptides are mixed with bacteriostatic water before lab use. Bacteriostatic water is simply water with a small amount of preservative added to stop bacteria from growing in the vial.

Working out the concentration is straightforward. Think of it like a drink mix: concentration equals the amount of peptide (in milligrams) divided by the amount of water added (in millilitres). For example, 5 mg of powder mixed into 2 mL of water gives a concentration of 2.5 mg/mL.

A reconstitution calculator is available at peptide calculator to check the math for a given vial and fill volume.

Dilution and handling notes (compound-specific)

BPC-157 is supplied as a freeze-dried powder, typically in 5 mg or 10 mg vials, and is reconstituted with a diluent before laboratory use.

Diluent volume is chosen based on the working concentration a protocol calls for. As a reference point, roughly 2 mL added to a 5 mg vial yields about 2.5 mg/mL, and roughly 3 mL added to a 10 mg vial yields about 3.3 mg/mL. A larger diluent volume produces a more dilute solution that is easier to measure in small increments; a smaller volume produces a more concentrated solution in less liquid.

Diluent selection

Sterile water and bacteriostatic water (sterile water with added benzyl alcohol) are the two diluents most commonly referenced in reconstitution protocols. Benzyl alcohol is a preservative, and published peptide-stability literature notes it can interact with some peptide backbones over time, so diluent choice is a variable worth recording and controlling for alongside temperature and light exposure when comparing results.

Mixing and solubility

BPC-157 powder dissolves readily in solution, typically within a few minutes, producing a clear, colorless liquid at normal working concentrations. It does not typically clump or leave visible precipitate at these concentrations. A solution that stays cloudy, develops floating particles, or changes color after mixing indicates an atypical result and should not be treated as usable material.

Handling best practices

To support clean dissolution, add diluent slowly down the interior glass wall of the vial rather than directly onto the powder cake, then swirl gently instead of shaking. Shaking introduces foam, and the air-liquid interface created by agitation is a known site of peptide degradation. After mixing, confirm the solution is fully clear before further use, and store the vial away from direct light.

Handling and storage

Proper storage habits protect a reconstituted vial from the two things that degrade it fastest: heat and light.

• Store the reconstituted vial in a refrigerator at 2 to 8 degrees Celsius, away from light. Avoid the freezer, direct sunlight, and windowsills.
• Wipe the rubber stopper with a fresh alcohol swab before every puncture to limit contamination each time the vial is accessed.
• Label the vial with the reconstitution date right after mixing, so its age is tracked at a glance rather than estimated later.
• A refrigerated working window of roughly four weeks (about 28 days) is commonly cited for solutions prepared with bacteriostatic water; treat this as a general reference point, not a fixed rule for every mix.
• Discard any vial that turns cloudy or discolored, or that shows floating particles or sediment - these are visual cues the solution should not be used further.
