BPC-157
BPC-157 is a regenerative peptide that supports tissue repair, recovery and gut health. It is designed to accelerate the healing of tendons, muscles and the digestive tract, and it helps reduce inflammation.
At the clinic, BPC-157 comes in two forms:
BPC-157 injectable (5 mg vial) for tissue and injury recovery, injected under the skin once a day.
BPC-157 oral (30 capsules) for gut and tissue repair, with no needles needed.
Both are USA-sourced with a batch Certificate of Analysis (COA) and are prescribed only after an in-person consultation, where your doctor decides which form, and which dose, suits your condition.
What it is and how it works
BPC-157 (Body Protection Compound-157) is based on a protective peptide (a small protein) found in the stomach; the BPC-157 we use is a synthetic peptide made from this sequence. Think of it as a "repair signal" that tells your body to heal faster and better. It has been studied by researchers around the world for its role in tissue repair and recovery, and because of its gastric origin it has also been explored in gastrointestinal research.
BPC-157 helps your body repair itself in several ways:
Speeds up healing. Whether you have a muscle tear, tendon injury or ligament damage, BPC-157 tells your repair cells to work faster and smarter.
Repairs the gut. If you suffer from stomach problems, IBS, bloating or leaky gut, BPC-157 repairs the lining of the digestive system, so you absorb nutrients better.
Reduces pain and inflammation. It acts like a natural anti-inflammatory, calming swelling and discomfort without harsh side effects.
Protects your organs. It shields the liver, heart and digestive organs from damage, especially from alcohol, medications or stress.
Helps the brain. It supports brain health, mood and recovery from head injuries.
Supports recovery after surgery. It shortens healing time and reduces post-surgery inflammation.
Unlike cortisone or anti-inflammatory drugs (NSAIDs), which reduce inflammation in the short term but can slow healing in the long term, BPC-157 works with your body's own repair system to heal properly and reduce inflammation.
Injectable or oral?
Injectable (more targeted): suited to specific injuries, such as the knee, elbow, shoulder or Achilles tendon, with faster results for localized problems. It is injected under the skin (subcutaneously), which gives full absorption.
Oral capsules (easiest): great for stomach problems and overall healing, and no needles are needed.
Please note that research on BPC-157 in humans is limited. Much of the available evidence comes from preclinical (animal and laboratory) studies and reviews, and BPC-157 is considered investigational in many settings.
What it is for

Anyone supporting liver health
Who should not have it
Do not use BPC-157, or seek medical advice first, if you have:
A history of cancer, active cancer, or ongoing cancer treatment
Von Hippel-Lindau disease (a rare genetic condition)
Pregnancy or breastfeeding
A known allergy to any component
Significant uncontrolled medical conditions
Competitive athletes: BPC-157 is on the World Anti-Doping Agency (WADA) Prohibited List (S0: non-approved substances) and is prohibited in sport. Do not use it if you compete in drug-tested sports.
There is no well-established interaction profile for BPC-157 in humans because clinical data are limited. Please tell your doctor if you use:
Blood thinners or antiplatelet medicines
Steroids or immunosuppressants
Diabetes medications
Any other injectable therapies or "peptide stacks"
The treatment
Every peptide starts with an in-person doctor consultation. Your doctor reviews your medical history, your current medicines and your injury or gut problem, then recommends the injectable or oral form and a personalized dose.
With the injectable form, you inject yourself at home once a day. The nurse teaches your first injection in clinic, and every peptide comes with a complete injection kit. With the oral form, you simply take your capsules at home. The length of your treatment is always set by your doctor after an in-person assessment, and several treatments can be combined on the same day, as your doctor advises.
How long to take it
Short-term, acute injuries: about 4–6 weeks in total.
Recovery after surgery: about 6–8 weeks in total.
One-time healing goals: take it daily until healed, then stop. No cycling is needed for these.
Serious injuries: some people take it for 3–6 months for complete recovery.
Cycling for longer-term use
For longer-term use, we follow a strategic pause protocol based on recent peptide research and clinical experience: 2 months on, 1 month off. Your body's repair receptors work best when given periodic breaks. Continuous daily use can reduce effectiveness over time, and pauses allow the receptors to "reset" and respond strongly when you resume treatment.
What results to expect
Most people notice:
Less pain and swelling within 1–2 weeks
Better digestion and less bloating
Faster recovery from workouts
Improved energy and mood
Noticeably faster healing of injuries
Better overall mobility and flexibility
Results vary with your condition, but consistent use over 4–8 weeks shows the best outcomes.

How to prepare and inject at home
This section applies to the injectable form. The nurse teaches your first injection in clinic, and your peptide comes with an injection kit containing everything you need. These are the steps you will follow at home.
1. Mix the peptide (once per vial)
Wash your hands and clean the tops of both vials (the sterile water and the peptide powder) with an alcohol swab. Draw the prescribed amount of sterile water into the syringe and inject it slowly down the inside wall of the peptide powder vial, rather than straight onto the powder. Gently swirl the vial until the solution is clear. Do not shake it.
2. Draw the dose
Clean the vial top with an alcohol swab and let it dry. Draw air into the syringe equal to your prescribed dose and inject that air into the vial. Turn the vial upside down and draw the correct number of units. Remove any air bubbles and recheck the dose.
3. Inject
Choose an injection site on the abdomen, staying 2–3 cm away from the navel, and rotate sites each time. Clean the skin with an alcohol swab and let it dry. Pinch a small fold of skin, insert the needle at 90° (or at 45° if you are very lean), and inject slowly. Wait 2–3 seconds, then remove the needle.
4. Store and dispose safely
Never reuse needles or syringes. Place used needles and syringes into a sharps container, or a hard plastic bottle with a secure lid.
Storage
Injectable: once mixed, keep the vial in the refrigerator at 2–8 °C. Label it with the date and time you mixed it, and use it within 30 days of mixing.
Oral capsules: keep them at room temperature (20–25 °C) in a cool, dry place away from direct sunlight, in the original sealed bottle or an airtight container, away from heat, humidity, moisture and light. The refrigerator is not needed and can cause moisture.
Before and aftercare
Tell your doctor about all the medicines you take, so we can check for interactions. We review your full medical history before you start.
Take oral capsules on an empty stomach; rotate injection sites if you use the injectable form.
Possible side effects are usually mild and can include redness, tenderness, swelling or itching at the injection site; headache, fatigue or dizziness (reported anecdotally or in observational reports); digestive discomfort in some people; and slight weight gain from better nutrient absorption. Report any unusual or persistent symptoms to your doctor.
Quality and safety
An in-person doctor consultation first. Your treatment plan and follow-up are overseen by the doctors, to reduce the risks of incorrect dosing, contamination or poor injection technique, and to find the best dose for your condition.
USA-sourced, with a batch Certificate of Analysis. We use USA-sourced BPC-157 from carefully selected suppliers that meet strict quality standards, tested for purity and quality. Each batch is supported by a COA from an independent third-party laboratory confirming identity and purity by HPLC. To protect the documents from copying or misuse, COAs are not sent electronically; you can review the originals in person at your consultation.
The nurse teaches your first injection in clinic.
Injection kit included. For the injectable form we prepare the full set: vial, sterile water, a mixing syringe, insulin syringes with needles, alcohol swabs and written instructions, with the number of supplies your protocol needs plus 2 extra kits as a backup. Additional injection sets are available if needed.
Medical cold chain. Peptides are fragile proteins that break down in heat, so we keep them in a medical cold chain until they reach you. Black-market peptides are often shipped without temperature control and have been found to contain heavy metals, bacterial endotoxins, residual solvents or incorrect sequences and doses.
Follow-up. Our peptide therapy is run by a dedicated peptide department with its own communication and follow-up system, under the guidance of the medical team.
Please note that orders of several vials may need up to 3 days before pick-up, depending on stock.
The science
Tendon and musculoskeletal healing
Laboratory studies show that BPC-157 promotes tendon healing and enhances growth hormone receptor expression in tendon fibroblasts. Reviews in orthopaedic sports medicine describe its emerging use for musculoskeletal healing but note that the evidence is mainly preclinical and clinical safety data are lacking.

Frequently asked questions
What is the difference between injectable and oral BPC-157?
The injectable form (5 mg vial, one injection under the skin daily) is more targeted and suits specific injuries such as the knee, elbow, shoulder or Achilles tendon. The oral form (30 capsules) is the easiest option, needs no needles, and is especially good for stomach problems and overall healing. Your doctor recommends the right form for you.
How long does it take to see results?
Most people notice improvements within 1–2 weeks: less pain, better digestion or reduced swelling. The real healing happens over 4–8 weeks of consistent use. Think of it like physical therapy: you see small improvements quickly, but major results take time. For serious injuries, some people take it for 3–6 months for complete recovery.
Is it safe?
BPC-157 has a good safety record, with serious side effects reported very rarely. Occasionally people experience mild itching or redness at the injection site or slight weight gain. By comparison, NSAIDs can cause stomach ulcers and bleeding, cortisone can weaken bones and suppress the immune system, and surgery means weeks of recovery. Human research is still limited, however, which is why BPC-157 is prescribed only after a doctor consultation and with follow-up.
Can I take BPC-157 with other medications?
Yes, BPC-157 can be taken with most medications, and it may even help protect your stomach from the side effects of painkillers and other drugs. Always tell us what medicines you take, especially blood thinners, steroids, immunosuppressants or diabetes medicines, so we can check for interactions. We review your full medical history before you start.
Will I gain weight on BPC-157?
Some people do gain a little weight. Because BPC-157 repairs the gut lining, you absorb nutrients better than before. If you were losing nutrients through leaky gut or digestive problems, you will now build more muscle and retain more of what you eat. This is a sign it is working. If you are concerned, we can adjust your nutrition plan.
Can I combine BPC-157 with other peptides?
Yes. BPC-157 works well with other peptides such as TB-500 (Thymosin Beta-4) for systemic healing, or IGF-1 for muscle growth. Many of our patients use BPC-157 as their "foundation" peptide and add others for specific goals, and we create a personalized peptide stack based on your needs.
How is BPC-157 different from cortisone or anti-inflammatory drugs?
Cortisone and NSAIDs reduce inflammation in the short term but can slow healing in the long term. BPC-157 works with your body's repair system to heal properly and reduce inflammation. It can even be combined with corticosteroids: BPC-157 prevents the steroid from slowing your healing, while the steroid handles the acute inflammation.
Do I need to take it continuously?
Not always. For acute injuries or post-surgery recovery, take it daily until healed, then stop. For longer-term use, we recommend cycling: 2 months on, 1 month off.
What is a COA?
A Certificate of Analysis is a laboratory document that reports key quality checks, such as identity and purity testing, for a batch. You can review the original COA in person at the clinic.
Do you provide injection supplies?
Yes. For the injectable form we prepare a complete kit (vial, sterile water, syringes and needles, alcohol swabs and instructions), with 2 extra kits as a backup. Additional injection sets are available if needed.
