Class of Compound:
Mechanism of Action:
BPC-157 is known to stimulate vascular endothelial growth factor, which triggers the formation of blood vessels. Also, it blocks the growth-inhibiting action of 4‐hydroxynonenal. Further, it upregulates multiple growth receptors in the body and stimulates the production of fibroblasts, vital to the synthesis of collagen.

What is BPC-157?
BPC-157 refers to Body Protection Compound-157, a naturally occurring peptide found in human stomach juices. Composed of a sequence of 15 amino acids, the peptide can also be found in trace amounts in the gastric fluids of other mammals.
The peptide plays a fundamental role in preserving the lining of the GI tract. However, researchers are interested in its application in other areas of the body—particularly in regards to wound healing, neuroprotection, and muscle and tissue growth.
Much of the research on BPC-157 to date has been done in animals, but researchers are now using the findings to date to help direct further research into the ways BPC-157 may be beneficial for human subjects.
It’s important to understand the potential side effects and risks of BPC-157 - along with dosing considerations, and legal status of the peptide - before purchasing it for research.
Our research team covers all of these questions below, before providing our top recommendation on where qualified researchers can buy BPC-157 online.
What Does BPC-157 Do?
BPC-157 was first isolated from body protection compound (BPC), which is found in the gastric juices and is part of the digestive process . It is composed of 15 amino acids, with the following chemical composition:
The role of BPC in the gastric juice is an important one. As a compound that can promote healing, it helps protect the gastrointestinal tissues from damage and can help prevent and heal stomach ulcers or other injuries to the intestinal lining.
It also promotes angiogenesis, or the formation of new blood vessels, allowing for increased oxygenation to the tissues.
Because of these properties, isolated BPC-157 is of great interest to researchers. The peptide shows potential in a number of applications outside of the GI tract, including in its promotion of healing, muscle growth and repair, and injury recovery.
BPC-157 Benefits | Clinical Trials
Researchers have identified numerous potential benefits of BPC-157 in both animal and human studies, although the evidence available in humans is extremely limited at this time.
Here are some of the potential benefits of BPC-157:
Connects the brain and the digestive system: BPC-157 may play a role in the gut-brain axis, or the direct line of communication between the nervous system and the digestive system. Perhaps surprisingly, the two are deeply interconnected—with digestive health playing a significant role in neurological health and cognitive function .
Neuroprotection: BPC-157 has been shown to provide some neuroprotective effects in rats, helping to protect against harmful free radical damage or protect the brain and preserve brain function after exposure to harmful substances .
Improved memory: BPC-157 may help improve and preserve memory as a result of its neuroprotective effects.
Mood regulation: Its neuroprotective effects may also help with mood regulation.
Blood flow and angiogenesis: One of the most promising potential benefits of BPC-157 is its angiogenic effect, or its ability to promote the formation of new blood vessels, which may help improve vasculature and blood flow. This effect has been noted in rat studies .
Blood pressure regulation: Because of its angiogenic effect, researchers have noted that BPC-157 also helps to regulate blood pressure in rat studies. BPC-157 may also activate nitric oxide pathways in the body, which causes vasodilation (blood vessel relaxing) that promotes both reduced blood pressure and better blood flow [4, 5, 6].
Reduced physical discomfort: Some early animal research suggests that BPC-157 may have nociceptive (pain relieving) properties. This effect was actually noted in a small chart review in humans—one of the few uses of BPC-157 that has human evidence at this time .
Increased energy: Because it can activate NO pathways, BPC-157 may help provide an energy boost. NO activators are a common ingredient in preworkout supplements .
Wound healing: The angiogenic properties of BPC-157 may also promote faster wound healing. It naturally occurs in the gastric juice and helps to prevent gastric ulcers, and researchers have found that it also helps promote faster healing of wounds in rats .
Liver protection: In animal studies, BPC-157 may be able to help protect the stomach, liver, and other tissues from NSAID medication overdoses. Researchers theorize it may offer similar protective benefits against alcohol and other toxins .
Muscle and tissue growth: In test-tube studies, BPC-157 stimulates growth hormone receptor expression—signaling the body to create new tendon tissue. It may also offer similar effects for bone, skin, and muscle .

BPC-157 Side Effects
There is little scientific documentation of BPC-157 side effects in humans, so most potential side effects are extrapolated from animal studies and anecdotal reports of human use.
The most common side effects appear to be related to the method of administration, which is typically intramuscular or subcutaneous injection. Common side effects of injections include redness, swelling, itching or skin reactions at the injection site. When these reactions are mild, they typically aren’t cause for concern.
In addition, because BPC-157 is a gastric peptide, there have been some informal reports of digestive side effects like nausea, diarrhea, gas and bloating related to its administration.
As an angiogenic agent, it’s theoretically possible for BPC-157 to have negative effects on blood pressure or heart rhythm in certain individuals.
Finally, there have been other anecdotal reports of dizziness, fatigue, headaches and appetite changes related to BPC-157. We reiterate that there have been no definitive human studies investigating BPC-157 side effects.
BPC-157 administration and dosing should be handled by a researcher who is familiar with BPC-157. Under no circumstances should it be purchased for self-administration or unauthorized experimentation.
Is BPC-157 Safe?
The peptide BPC-157 has not been evaluated for safety as part of the drug review process of the United States Food and Drug Administration (FDA), nor has it been formally evaluated for safety by any international regulatory counterpart of the FDA. Therefore, any claims or insinuations that BPC-157 is “safe” must be taken with a grain of salt.
However, in published research to date, BPC-157 administration has produced minimal side effects in both animals and humans. Specifically, a review of clinical trials on the use of BPC-157 has characterized it as safe both in treating inflammatory bowel disease and wound healing, noting that no events of toxicity had been reported throughout those trials .
In fact, the peptide has actually been shown to prevent severe side effects associated with medications for diabetes and psychiatric conditions, including catalepsy, somatosensory disturbance, and QTc prolongation in the heart—which can lead to fatal arrythmia [13, 14].
As with any research involving peptides, prudence and caution are required when administering BPC-157 to test subjects.
BPC-157 Dosage Calculator
Again, there is little research available in humans on BPC-157, so most dosage recommendations are loosely based on equivalent doses used in animal studies and anecdotal reports of human use.
In general, the most widely agreed upon daily dose of BPC-157 is about 250 mcg, delivered via intramuscular injection. A general rule of thumb that may be utilized by researchers is 2-4 mcg per kg of body weight.
However, there are other forms of BPC-157 available - in particular, sublingual tablets which are dissolved under the tongue.
Regardless, most research applications utilize the injected version, and this is also the form that is most often used in both research and clinical settings.
