What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic peptide comprising 15 amino acids, thus making it a pentadecapeptide.
It was first developed in 1991 as a derivative of Body Protection Compound, a peptide naturally found in human gastric juices [1, 2].
BPC-157 was initially investigated for preventing and managing stomach ulcers, and further research delved into its potential for improving wound and injury healing in test subjects [3].
Researchers posit that there are multiple mechanisms through which BPC-157 promotes healing effects when administered to test subjects:
- BPC-157 is notably thought to work by stimulating the formation of blood vessels, in a process known as angiogenesis. It may achieve this by upregulating vascular endothelial growth factor (VEGF), an endogenous protein responsible for stimulating the growth of new blood vessels [4].
- BPC-157 may also upregulate the expression of early growth response gene-1 (EGR-1), which is a growth factor with potential benefits for the nervous system, having been suggested to aid in early extracellular matrix (collagen) formation [5].
- Researchers also suggest that BPC-157 increases blood flow in the body by increasing the production and release of nitric oxide (NO). In fact, animal studies into the effects of BPC-157 on nitric oxide have shown that it can accelerate recovery rates in a wide variety of injuries [6].
As of writing, no clinical studies are available on the effects and safety of BPC-157. Thus, it remains classed as a research chemical that is available for laboratory experimentation.
Research Application and Potential Benefits of BPC-157
BPC-157 has been studied for its potential benefits in various tissue and healing models.
Researchers have demonstrated its potential to reduce inflammation, speed up wound healing, and hasten recovery from various injuries.
BPC-157 and Musculoskeletal Injuries
Below we detail some of the more notable animal experiments that report on the healing potential of BPC-157.
- Animal studies indicate BPC-157 may aid in healing injuries—particularly of tendons, muscles, and bones—by promoting angiogenesis and fibroblast growth [7].
- In vitro research on cut tendons suggests that BPC-157 may enhance the migration of tendon fibroblasts to sites of injury [8].
- Research shows improved healing in animal models of crushed muscles treated with BPC-157 [4].
- Studies on the effects of BPC-157 on early Achilles tendon-to-bone recovery in rats demonstrate reduced inflammation and enhanced angiogenesis, collagen organization, and vascularity. The peptide was shown to counteract the negative effects of methylprednisolone [9, 10].
- Studies in rabbits with partially healed bone defects show significant improvement with BPC-157 injections, yielding effects comparable to bone marrow or cortical graft procedures [11].
- Additional animal injury models highlight the anti-inflammatory and pain reduction properties of BPC-157 [12, 13].
BPC-157 and Neuroprotection
Preliminary experiments also suggest that BPC-157 may have protective effects on nervous tissue, particularly in laboratory models of toxicity and traumatic brain injury.
- A 2014 study showed that BPC-157 reduced methamphetamine-induced neurotoxicity in rats, preserving more normal neurons compared to the control group [14].
- In a mouse model of traumatic brain injury (TBI), BPC-157 administration significantly lowered damage and mortality rates. Further, prophylactic use prior to TBI decreased the risk of unconsciousness or death [15].
BPC-157 and Wound Healing
BPC-157 has shown potential for the recovery of various injuries and wounds affecting the digestive system and the skin. Here are some notable findings to date:
- A rat study demonstrated that BPC-157 at high doses significantly boosted ileoileal anastomosis healing with minimal adhesions and increased granulation tissue and collagen [16].
- In rats with short bowel syndrome, BPC-157 caused immediate weight gain and improved intestinal features following oral and intraperitoneal administration [17].
- Reviews indicate the protective effects of BPC-157 on stomach cells following application of non-steroidal anti-inflammatory drugs (NSAIDs), as well as its role in maintaining gastric mucosa integrity [3, 18, 19].
- Studies also suggest that BPC-157 speeds up skin wound healing, as seen in rats with alkali burns treated topically with the peptide [20].
BPC-157 Dosage Calculator
There is currently a lack of clinical research that offers specific dosing guidelines for BPC-157.
As a result, the existing recommendations on how to dose this compound largely stem from animal studies and anecdotal reports.
Based on current information, we’ll outline how to estimate BPC-157 dosage in various experimental settings.
Dosing BPC-157 For Healing
Animal research exploring the healing capabilities of BPC-157 has mostly involved rodents, with doses reaching up to 10mcg/kg daily [21]. To calculate a comparable dosage to apply in clinical settings, researchers may refer to the dose conversion guidelines established by Nair et al. (2016).
Based on this publication, the conversion rate from rat to human doses is about 1:6.2. Therefore, a rat dosage of 10mcg/kg translates to roughly 1.61mcg/kg for human subjects [22]. This equates to approximately 0.73mcg/lb, or about 146mcg for an individual weighing 200lb.
Additionally, animal studies have administered BPC-157 for periods exceeding 14 days without observing any significant safety concerns or adverse effects [16]. Nevertheless, it is important to recognize that these findings may not directly translate to clinical settings.
Dosing BPC-157 Oral Capsules
Preclinical experiments reveal that BPC-157 may also be administered orally, such as in the form of BPC-157 capsules, especially during research related to gut healing. Yet, it is unknown if this formulation would exert primarily local effects on the digestive system, or if it would work systemically.
The BPC-157 oral doses used in preclinical studies is similar to those given in studies with injections at 10mcg/kg [21].
Anecdotal reports also suggest that research with oral formulations of BPC-157 may be conducted with similar dosages to the ones estimated via the aforementioned calculations. More specifically, the most widely speculated daily dosage for BPC-157 oral capsules is around 250mcg, typically administered 1-3 times daily.
Yet, more research is needed to evaluate and confirm the safety and effectiveness of such dosing regimes.
Dosing BPC-157 Nasal Spray
BPC-157 as a nasal spray may be a valuable tool for researchers interested in investigating the potential of BPC-157 for neuroprotection. Yet, similar to other BPC-157 formulations, there is no data on the proper dosing of BPC-157 nasal spray in research settings.
Therefore, researchers may consider using doses similar to those administered as BPC-157 injections or BPC-157 oral capsules.
BPC-157 + TB-500 Blend Dosage Calculator
BPC-157 is also commonly sold as a blend with TB-500.
TB-500 is a synthetic version of the endogenous protein called thymosin beta-4, which is found in most human and animal cells. Thymosin beta-4 promotes a variety of essential biological functions such as [22]:
- Reducing inflammation
- Angiogenesis
- Immune support
- Faster wound healing
Combining this compound with BPC-157 is thought to lead to synergistic healing effects, which has led to the development of peptide blends for use in such experiments. BPC-157 + TB-500 blends typically contain the two peptides in a ratio ranging from 1:1 to 1:5 in favor of TB-500.
This is because TB-500 research suggests that it can be applied in daily doses starting from 0.5mcg/kg of body weight up to considerably higher doses for 10-14 days [23, 24].
Based on this, anecdotal sources report a dose of 10-20mcg/kg, which would be equal to 1-2mg for a 200lb test subject.
Considering this information, dosing a 1:1 blend of BPC-157 + TB-500 at 1mcg/kg daily (0.5mcg/kg each) may be a decent starting point for most researchers.
How to Mix and Reconstitute BPC-157
BPC-157 for injection is typically shipped as a lyophilized powder that needs to be reconstituted using a sterile solvent such as bacteriostatic water.
This solvent contains 0.9% benzyl alcohol—a preservative that suppresses microbial growth and ensures a 4-week shelf-life of the peptide when refrigerated at 35-46°F (2-8°C).
Here is a short guide on how researchers can successfully reconstitute BPC-157.
Step 1: Collection of Required Materials
For the preparation process, researchers will need to gather several items, including:
- Bacteriostatic water
- Insulin syringes
- Alcohol pads
- Sterile storage vial
- 3cc syringe with needle
Step 2: Calculating Correct Volumes
Researchers may refer to this calculator tool to ascertain the precise volume of bacteriostatic water needed. This calculation is essential to achieve the desired concentration when mixed with BPC-157 powder.
Step 3: Combining Bacteriostatic Water and BPC-157 Powder
The process involves using a 3cc syringe and needle. Firstly, draw an amount of air equivalent to the required volume of bacteriostatic water. Then, insert the needle into the bacteriostatic water vial and release the air to prevent a vacuum effect. Next, withdraw the necessary volume of diluent. While mixing, angle the needle into the BPC-157 vial and carefully depress the plunger, guiding the water along the inner surface of the vial. After the syringe is emptied, remove it from the vial.
Step 4: Dissolution of the Peptide
It's crucial to avoid agitating the vial, whether by shaking or tapping. Instead, let the vial rest for 10 to 20 minutes or use sonication if available. This period allows the BPC-157 peptide to dissolve completely. In case any particles remain undissolved, gently roll the vial to aid in completing the reconstitution process.
This methodical approach ensures a precise and effective preparation of the peptide solution for research purposes, maintaining the integrity and effectiveness of the BPC-157.
How Much Bacteriostatic Water to Mix With 5mg of BPC-157?
Researchers aiming to reconstitute 5mg vials of BPC-157 may wonder how much bacteriostatic water to use during the process.
When reconstituting 5mg of BPC-157, scientists must note that the volume of solvent used can vary depending on the desired concentration. A common approach is to use a 1mL syringe for precision.
Thus, for a concentration of 1mg/mL, which is often used for ease of calculation, researchers can mix 5mg of BPC-157 with 5mL of bacteriostatic water. This allows for easy dosing where 0.25mL of the solution contains 250mcg of BPC-157.
Further, researchers should always use aseptic techniques to ensure the purity and sterility of the mixture and refer to the label of the peptide for accurate information on reconstitution, handling, and storage.
How Much Bacteriostatic Water to Mix With 10mg of BPC-157?
For reconstituting a 10mg vial of BPC-157, researchers can follow a similar approach. For example, scientists can use 10mL of bacteriostatic water and aim for a concentration of 1mg/mL, thus making calculations considerably easier.
Consequently, 0.25mL of the solution will again contain 250mcg of BPC-157.
This method ensures a precise concentration, facilitating accurate dosing for research purposes. The reconstituted peptide should be stored per recommended guidelines to maintain its stability and efficacy.
