BPC-157
Body Protection Compound-157
BPC-157 is a synthetic pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. It has been extensively studied in animal models for tissue repair, gut healing, tendon and ligament recovery, and neuroprotection. While no FDA-approved human trials exist, it is one of the most widely used research peptides in the biohacking and peptide therapy communities.
Quick Reference
Dosing Protocols
Dosing varies by goal. Most users inject subcutaneously near the injury site when targeting a specific area, or in the abdomen for systemic/gut applications.
Conservative / Beginner
250 mcg/day
Once daily
4–6 weeks
Standard starting point. Inject subcutaneously. Good for general healing and gut support.
Standard / Moderate
500 mcg/day
Once daily or split 250 mcg 2x/day
4–6 weeks
Most common protocol. Split dosing may maintain more stable levels. Inject near injury site if targeting a specific area.
Aggressive / Acute Injury
500–750 mcg/day
Split 2x/day
2–4 weeks
Used for acute injuries or post-surgical recovery. Higher doses for shorter durations. Monitor closely.
Oral / Gut-Focused
500 mcg/day
Once daily, on empty stomach
4–8 weeks
For gut healing (IBS, leaky gut, NSAID damage). Oral BPC-157 targets the GI tract directly. Some users combine oral + injectable.
Reconstitution Guide
BPC-157 comes as a lyophilized (freeze-dried) powder. You need to add bacteriostatic water (BAC water) before injecting.
Example: 5 mg vial + 2 mL BAC water
Concentration: 5,000 mcg ÷ 2 mL = 2,500 mcg/mL
For a 250 mcg dose: 250 ÷ 2,500 = 0.10 mL = 10 units on a 100-unit syringe
For a 500 mcg dose: 500 ÷ 2,500 = 0.20 mL = 20 units on a 100-unit syringe
Doses per vial: 5,000 ÷ 250 = 20 doses at 250 mcg
Steps to reconstitute
- Clean the vial stopper and BAC water stopper with alcohol swabs.
- Draw your desired amount of BAC water (typically 1–2 mL) into an insulin syringe.
- Insert the needle into the peptide vial at an angle, aiming at the glass wall — not directly onto the powder.
- Slowly release the water, letting it trickle down the side of the vial.
- Gently swirl the vial until the powder is fully dissolved. Do not shake.
- Store reconstituted vial in the refrigerator. Use within 4–6 weeks.

Injection Sites
BPC-157 is injected subcutaneously (into the fat layer just under the skin). Common injection sites:
- Near the injury — for localized tendon/ligament/muscle injuries, inject as close to the injury site as practical
- Abdomen (belly fat) — for systemic use or gut healing. Rotate injection sites to avoid lipodystrophy
- Love handles / flanks — alternative systemic site with good subcutaneous fat
Use a 29–31 gauge insulin syringe. Pinch the skin, insert the needle at a 45-degree angle, inject slowly, and hold for 5–10 seconds before withdrawing.
Side Effects
BPC-157 has a favorable safety profile in animal studies, with no reported organ toxicity at therapeutic doses. Reported side effects in the community are generally mild:
Injection site redness
Nausea
Dizziness
Headache
Fatigue / drowsiness
Increased appetite (oral)
Common Stacks
BPC-157 + TB-500
— Enhanced healingThe most popular healing stack. BPC-157 and TB-500 work through different mechanisms — BPC-157 promotes angiogenesis and growth factor expression, while TB-500 reduces inflammation and promotes cell migration. Often used for tendon, ligament, and joint injuries.
Typical dosing: BPC-157 250–500 mcg + TB-500 2–5 mg, 2x/week for TB-500, daily for BPC
BPC-157 + GHK-Cu
— Tissue remodelingCombines BPC-157's healing properties with GHK-Cu's collagen synthesis and skin remodeling effects. Used for post-surgical recovery and anti-aging protocols.
Typical dosing: BPC-157 250–500 mcg/day + GHK-Cu 1–2 mg/day
Cycling
Most users run BPC-157 in 4–6 week cycles. While there is no established evidence of receptor desensitization, cycling is a common precautionary practice.
Common patterns
- 4 weeks on / 2 weeks off — standard cycle for maintenance or minor injuries
- 6 weeks on / 4 weeks off — extended cycle for more significant injuries
- Until healed — some users run continuously for acute injuries, then stop when symptoms resolve
Research Summary
BPC-157 has been studied in over 100 animal studies across multiple tissue types. Key findings from published research:
Accelerated tendon-to-bone healing and improved biomechanical properties in rat Achilles tendon transection models
Chang et al., 2011, J Orthop Res
Counteracted NSAID-induced gut damage, healed esophageal and intestinal lesions, and reduced inflammatory markers in multiple GI models
Sikiric et al., 2018, Curr Pharm Des (review)
Improved functional recovery and reduced muscle atrophy following crush injuries in rat models
Pevec et al., 2010, J Physiol Pharmacol
Demonstrated neuroprotective effects in traumatic brain injury models and improved recovery of dopaminergic neurons
Tudor et al., 2010, J Physiol Pharmacol
Promoted new blood vessel formation (angiogenesis), supporting tissue repair through improved blood supply
Hsieh et al., 2017, Life Sci
Note: All cited studies are animal models. No FDA-approved human clinical trials have been completed for BPC-157 as of 2026.
FAQ
How long does it take for BPC-157 to work?
Most users report noticeable improvement within 1–2 weeks for acute injuries. Chronic conditions may take 3–4 weeks. Gut healing protocols typically show results within 2–3 weeks.
Can I take BPC-157 orally?
Yes. Oral BPC-157 (capsules or dissolved in water) is specifically effective for GI conditions. For injuries outside the gut, subcutaneous injection provides more targeted delivery.
Do I need to inject near the injury?
It helps but isn't strictly required. BPC-157 has systemic effects regardless of injection site. Injecting near the injury may provide faster local tissue repair, but abdominal injections are effective for general healing.
How should I store reconstituted BPC-157?
Refrigerate at 2–8°C (36–46°F). Reconstituted BPC-157 is stable for approximately 4–6 weeks when stored properly. Do not freeze reconstituted solution. Unreconstituted powder can be stored at room temperature or frozen.
Can I stack BPC-157 with TB-500?
Yes. BPC-157 + TB-500 is the most common healing peptide stack. They work through complementary mechanisms and are generally well-tolerated together.
Is BPC-157 legal?
BPC-157 is not FDA-approved for human use. It is classified as a research chemical. Legality varies by jurisdiction. It is not a controlled substance in the US but cannot be marketed for human consumption.
