Skeletal system
Structure of the skeletal system Schematically, let's recall the structure of the skeletal system, which mostly consists of bone tissue and cartilage tissue. This system is made up of about 206 bones, including long, short, flat, and irregular bones. The human skeleton can be divided into the axial skeleton and the appendicular skeleton. (Fig.1) The presented structure of the skeletal system will help us better understand and illustrate the effect of BPC-157 on its functioning.

Figure 1. Schematic representation of the musculoskeletal system structure
Functions of the skeletal system
The primary, well-known function of the skeletal system is to create a specific framework for our body, providing an upright posture and protection for all internal organs. Additionally, the system supports the muscles, with which it cooperates to form the locomotor system.
Muscular system
Structure of the muscular system The types of cells that make up the muscular system are striated muscle cells, i.e., skeletal muscles, striated heart cells, and smooth muscle cells without striation. Additionally, skeletal muscles are made up of myocytes or fibers consisting of myofibrils. Considering the morphological structure of the muscular system, the following are distinguished: the belly made of muscle fibers, the initial and final tendon, and the initial and final attachment. A schematic representation of the muscular system structure allows us to better understand the therapy with the BPC-157 peptide on this system.
Functions of the muscular system
The function of the muscular system includes the ability to move while performing precise movements simultaneously. Through its proper functioning, it is possible to maintain correct body posture and keep internal organs in a specific, fixed position. Injuries and dysfunctions of the bone-joint system, muscles, and tendons, which are influenced by BPC-157 therapeutic treatment Bone and joint injuries Any physical activity, especially in the world of sports and excessive physical exertion, can result in bone or joint injury. Bone and joint injuries include fractures, dislocations, or sprains. Each injury is accompanied by increasing pain, swelling, bruising, or limited mobility, which is why quick and effective therapy is so important to restore our freedom of movement and quality of life. One of the therapies helpful in such injuries is treatment with the BPC-157 peptide.
Muscle and joint injuries
The BPC-157 peptide is primarily recognized for its regenerative function, which is why it is used for muscle and tendon injuries. Just like in the case of bone and joint injuries, these injuries mostly occur in athletes, and the most common condition is muscle strain. Injuries are accompanied by pain and the inability to return to training or competition. Proper diagnosis and therapy can optimize the injury and speed up recovery. Therapy with the BPC-157 peptide is also part of this treatment.
Therapeutic BPC-157 treatment for selected injuries of the musculoskeletal system, muscles, and tendons based on research
- Bone fracture
Bone fractures most often occur as a result of injury but also during weakening of the bone tissue structure in disease processes, including infections or hereditary diseases. Almost any bone can fracture, and the most dangerous fracture is a compression fracture of the vertebrae. Bone fractures are accompanied by symptoms such as pain, inability to move, swelling, or puffiness.
a. BPC-157 Therapy The BPC-157 peptide allows for twice as fast healing of a broken bone. Fibroblasts forming at the fracture site, which create a scaffold structure made of calcium, cartilage, and collagen, develop faster in the presence of the peptide. During bone fracture healing, the new tissue is characterized by high fragility and delicacy, and BPC-157 supporting this process leads to greater strength and hardness, resulting in faster regeneration and bone union.
b. Conducted experimental studies
Study 1
Material Male rabbits subjected to appropriate preoperative nutrition.
Examination procedure On the left front paws of rabbits, under deep anesthesia, an incision was made on the surface of the radius shaft. The wound was rinsed with saline and closed. To obtain and compare results, an X-ray of the injured paw was taken immediately after the procedure. Then the paw was immobilized with a plaster splint. The rabbits were given antibiotics. Some rabbits were assigned to the control group, while the second group was given an intramuscular injection of the BPC-157 peptide at a dose of 10 mg/kg body weight. The results are presented based on X-ray images taken after the injury healed. Unmineralized, isolated bone specimens are observed under a microscope for damage analysis. Results The surface area of the callus formed during bone healing in the group treated with the BPC-157 peptide is twice as large as in the control group during the same recovery period.
Conclusions In the case of bone fractures, therapy with the BPC-157 peptide is a very effective method. The peptide accelerates the healing of fractures as well as various bone defects and losses. It should be noted that this therapy allows achieving the effect of bone union, which simultaneously become stronger and less susceptible to injuries that may occur in the future.
- Tendon damage/rupture
Muscle damage or rupture is one of the most serious and common soft tissue injuries. This condition is encountered both in professional athletes and in people who engage in sports only recreationally or sporadically. The concept of tendon rupture is described as a complete disruption of the continuity of the tendon fibers connecting the muscle to the bone. The most frequently torn and damaged tendons are the Achilles tendon and the knee tendon. The direct cause of tendon rupture is considered to be excessive force acting on the muscle at a given moment. It most often occurs as a result of an indirect injury, when a sudden contraction of the tendon happens, for example during a sudden jump or exertion without prior preparation. A previous inflammatory condition of the tendon is also considered a cause of tendon rupture. Symptoms accompanying muscle rupture include sudden and severe pain, swelling, immobilization, and subcutaneous hemorrhages.
a. BPC-157 Therapy
A damaged tendon, for the proper functioning of the muscular system and the body, requires regeneration and reconstruction. The regeneration process without any therapy is long and tedious. For better regenerative effects in a shorter period of time, therapy with the BPC-157 peptide is used. The peptide supports the damaged tendon for faster remodeling to enable reconstruction. Thanks to the action of BPC-157, the recovery period after tendon injury is significantly shorter.
b. Conducted experimental studies
Study 2
Material Male albino rats weighing between 280-320 g.
Study procedure Male rats were subjected to light anesthesia. The Achilles tendon was transversely cut to create a defect on its surface. BPC-157 at doses of 10 ug, 10 ng, or 10 pg, along with saline, was applied 30 minutes after the procedure. The results were analyzed using computer imaging by observing the spread of the rats' toes, where their total spread indicated significant tendon damage. During the histological study, samples of the damaged tendon were taken, cut into smaller pieces, and changes were observed under a microscope in the presence of the peptide BPC-157 and without it. Results In untreated rats, a large defect appeared between the cut ends of the Achilles tendon. Administration of the peptide BPC-157 after injury brought positive results, initiating faster, more intense, and advanced regeneration of the Achilles tendon. Collagen fibers with peptide therapy are denser and regularly arranged. The defect disappears several days earlier compared to the untreated group and other possible supportive therapies.
Conclusions
During BPC-157 therapy, improvement in healing and tissue strength was observed during Achilles tendon regeneration, demonstrating the ability for faster and more effective regeneration of all tendons.
- Muscle injury
Muscle injury can be defined in various ways. The most important of these concerns acute damage caused by excessive and sudden pressure on the muscles, most often during physical exertion. Muscle fibers are torn, and accompanying symptoms such as pain, loss of strength, swelling, or bleeding eliminate us from sports activities as well as proper, normal functioning. Most often, tendons around the thigh or knee are injured. Meanwhile, muscle tension over a longer period causes injury in the area of the back, groin, legs, or arms. a.Therapy with BPC-157 As with tendons, a damaged muscle, for the proper functioning of the muscular system and the body, requires regeneration and rebuilding. The regeneration process without any therapy is long and tedious. For better regenerative effects in a shorter period, therapy with the peptide BPC-157 is used. The peptide supports the damaged muscle for faster remodeling to rebuild. Thanks to the action of BPC-157, the recovery period after tendon injury is significantly shorter.
b. Conducted experimental studies
Study 3
Material Male albino rats weighing from 230 to 320 g.
Examination procedure Rats experienced mechanical crushing of the muscle. After the injury, the BPC-157 peptide was administered intraperitoneally at doses of 10 µg/kg and 10 ng/kg. Effectiveness was assessed on days 1, 2, 4, 7, and 14 after the injury. The circumference of the swelling as well as hematomas and erythema resulting from the injury were observed on a scale from 0 to 3, where 0 means no injury and 3 means severe injury. The control group of rats was not given the BPC-157 peptide. Results In muscles regenerated with BPC-157, rapid reconstruction and restoration of their function were observed. The proliferation process is restored, inflammation is alleviated. There is an absence of unwanted muscle spasms. In the control group, no regenerative processes were observed in the near term, which was evident in the impaired gait of the subjects. Conclusions BPC-157 therapy is helpful in injuries concerning the muscular system. All muscle damage, including strains or muscle injuries, is regenerated more effectively during peptide therapy.
Therapeutic BPC-157 therapy after undergone procedures and surgeries of the musculoskeletal system in relation to studies
Surgical procedures
Surgical procedures related to the skeletal system involve significant intervention in the structure of bones and soft tissues. Increasingly, less invasive techniques are being used, which are equally precise and effective. Every procedure and operation aims for a quick repair of the injury, a short hospitalization time, a return to fitness, and minimizing postoperative scars. The recovery time after surgery ranges from three to six months. Through certain actions, the convalescence period can be shortened or alleviated. One of these actions is therapy with the BPC-157 peptide. a. BPC-157 Therapy It has been observed that postoperative therapy using the BPC-157 peptide yields satisfactory results and can lead to a faster return to physical fitness, reduce pain, and shorten the recovery period due to its regenerative abilities. The peptide alleviates the effects of intervention in the structure of bones and soft tissue.
b. Conducted experimental studies
Study 4
Material Female albino rats were studied under temperature conditions of 22.4 °C, humidity ranging from 40-70%, for a period of 5 days while maintaining fluorescent lighting for 12 hours daily.
Study procedure Female rats were deeply anesthetized using 3% isoflurane and 50 mg/kg ketamine. A procedure was performed involving the removal of the vertebral arches along with the ligamentum flavum (laminectomy) at the lumbar level corresponding to the spinal cord segment. In one group, only saline solution was administered after the procedure, forming the control group. In the second group, the peptide BPC-157 was injected intraperitoneally at a dose of 200 μg/kg b.w. or 2 μg/kg b.w. along with 0.9% NaCl 5 ml/kg b.w. The animals were observed to detect secondary spinal cord injury or other trauma. The observation focused on tail motor functions, assessing their loss on a scale of 1-5, where 1 indicates complete loss of function and 5 normal, preserved tail functions. Observations were made from 10 minutes up to 360 days after BPC-157 administration. The next stage of the study involved euthanizing the rat and collecting a segment of its spine. The part used for analysis was the gray and white matter of the spinal cord. Before analysis, the material was subjected to histological processing, including fixation in 4% formaldehyde in phosphate buffer, deparaffinization of sections in xylene, hydration in ethanol solutions, staining with hematoxylin and toluidine blue. Changes were observed under a light microscope. The evaluation scale in this case ranged from 0-3, where 0 meant no changes and 3 numerous changes within the spinal cord. Results In rats that were injected only with saline solution after the procedure, tail motor functions were significantly weakened. In the group of female rats given the peptide BPC-157, improved tail motor function was noticeable, especially after longer peptide therapy (180 days). Additionally, spasticity, i.e., abnormal, excessive muscle tension, was observed in the control group, whereas in the group undergoing BPC-157 therapy this symptom was inhibited.
In the microscopic image, we observed visible swelling that developed within 30 days from mechanical injury caused during the examination. In control animals not qualified for BPC-157 therapy, these swellings are of significant size. In animals subjected to BPC-157 therapy at a dose of 2 μg/kg, minimal swelling changes are noticeable, while at a dose of 200 μg/kg, no changes are observed compared to healthy individuals.
Conclusions
Therapy with the BPC-157 peptide stimulates the regeneration of injuries within the spine, reduces spinal swelling, eliminating redness at the site of its occurrence and lowering the temperature there, thereby relieving pain. BPC-157 supports post-surgical treatment after procedures or operations of the musculoskeletal system, simultaneously improving and restoring motor functions for better quality of life.
Therapeutic BPC-157 therapy in the treatment of skin injuries and burns with reference to research
- Skin burns
A burn is a type of skin injury and, using it as an example, the assistance provided by BPC-157 peptide therapy will also be discussed in the case of cuts, scars, and wounds. A burn is a skin injury that can affect only the epidermis but also deeper tissues. This damage occurs due to heat, chemicals, electric shock, or thermal factors. Increased vascular permeability in burns leads to tissue necrosis and loss of bodily fluids. Burns are primarily accompanied by severe pain and discomfort. a. BPC-157 Therapy Thanks to BPC-157 peptide therapy, new tissue forms faster with a simultaneously higher level of collagenase, which causes wounds, cuts, or burns to heal more quickly. As is known, the peptide promotes the action of vascular endothelial growth factor VEGF, which causes the formation of new blood vessels supporting skin regeneration processes. Cell proliferation is accelerated, making wound healing faster and more effective, and scars resulting from such injuries are smaller and flattened.
b.Experimental study conducted
Study 5
Material Male rats of specified weight and breed, under temperature conditions of 25 °C and humidity between 50-60%.
Study procedure Rats were deeply anesthetized using pentobarbital at a dose of 50mg/kg. Anesthesia was administered via intraperitoneal injection. Additionally, the hair on the backs of the rats was removed. The skin burn was performed mechanically, using alkalis that are oxides exhibiting strongly basic properties. For 75 seconds, filter paper soaked in 2M NaOH was placed on the previously prepared, shaved skin of the rat. Rats in the control group were given only saline solution and hydrogel was applied, while the subjects tested for BPC-157 peptide therapy were given appropriate doses of 200 ng/ml, 400 ng/ml, and 800 ng/ml. To assess wound healing, an acetate sheet was used, placing it daily on the resulting wound. The rate of wound closure was expressed as a percentage. Results According to the results, it was found that BPC-157 accelerates wound healing, applying to both burns and cuts. BPC-157 promotes fibroblast proliferation and increases collagenase synthesis. The higher the dose, the faster and less painful the wound closure process. After 18 days, wound closure with the help of the BPC-157 peptide reached about 80%. Compared to untreated control wounds, this is almost twice as fast. Increased collagenase synthesis is characterized by good organization of the epidermal and suprabasal layers, whereas in the control group, during healing, a thin and immature epithelium can be observed for a longer period. Conclusions Any skin injury results in a convalescence period and later one may struggle with scars formed as a result. In both cases, therapy with the BPC-157 peptide is used to alleviate symptoms both immediately after injury and during treatment and mitigation of its effects.
Summary
Proper functioning of the musculoskeletal system, muscles, as well as the elasticity and continuity of our skin is essential for the comfort of our lives. The presented broad spectrum of regenerative action of BPC-157 allows it to be classified as a substance with therapeutic effects. Systematic use of the peptide will enable the recovery of the motor system, which is necessary for movement. A significant number of studies show that BPC-157 in the form of gastric administration (through capsules or dissolving the substance in water) exhibits equally effective action on our musculoskeletal system and skin as injection administration. It can be stated that BPC-157 in the form of a stable salt is a precursor in regenerative treatment after surgeries and injuries of the musculoskeletal system, muscles, and skin injuries.
