BPC-157 Dosage Guide
Evidence-based protocols for Body Protection Compound-157 — subcutaneous and oral dosing, reconstitution, injection technique, stacking with TB-500, cycling, and safety.
In This Guide
What Is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide (15 amino acids) derived from a naturally occurring protein found in human gastric juice. It was first isolated and characterized by researchers studying the protective mechanisms of the gastrointestinal tract. Unlike most peptides used in research, BPC-157 is remarkably stable in stomach acid — a property that allows it to be administered both by injection and orally.
BPC-157's primary research interest centers on its tissue-protective and regenerative properties. Animal studies have demonstrated accelerated healing of tendons, ligaments, muscles, nerves, the GI tract, and even bone. Its mechanism of action involves upregulation of growth factor expression (particularly VEGF and EGF), promotion of angiogenesis (new blood vessel formation), modulation of the nitric oxide (NO) system, and interaction with the dopaminergic and GABAergic systems. This guide covers dosing protocols for subcutaneous injection and oral administration, reconstitution, injection technique, stacking with TB-500, cycling, and safety considerations.

Key Characteristics:
- Pentadecapeptide — 15 amino acids, sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
- Gastric juice-derived — isolated from human gastric juice proteins; stable in stomach acid, which is unusual for peptides
- Multi-route administration — active both by subcutaneous/intramuscular injection and oral administration, unlike most research peptides
- Tissue repair and protection — promotes healing of tendons, ligaments, muscles, gut lining, nerves, and bone in animal models
- Angiogenesis promotion — upregulates VEGF (vascular endothelial growth factor), promoting new blood vessel formation at injury sites
- NO system modulation — interacts with the nitric oxide system, which plays a key role in blood flow, inflammation, and tissue repair signaling

How BPC-157 Dosage Is Determined
BPC-157 dosing — expressed in micrograms (mcg) per injection or per day — is derived from animal studies, allometric scaling from rodent models to estimated human equivalent doses, and extensive community experience. No human clinical trials have established an official dosing regimen. The commonly used 200–300 mcg range is based on a combination of translated research data and years of anecdotal reporting.
Animal Studies
The majority of BPC-157 research has been conducted in rodent models. Doses in these studies typically range from 10 mcg/kg to 10 mg/kg, administered intraperitoneally, subcutaneously, intragastrically, or applied topically to wounds. Positive results on tendon healing, gastric ulcer repair, and nerve regeneration have been observed across a wide dose range, with most studies using 10–50 mcg/kg.
Allometric Scaling to Human Doses
Community dosing protocols are loosely based on allometric scaling from effective rodent doses. A commonly cited rat dose of 10 mcg/kg, when scaled to a 75 kg human using standard surface area conversion factors, yields approximately 200–300 mcg as a reasonable starting point. This is a rough estimate — not a precise pharmaceutical calculation.
Community & Practitioner Experience
Over the past decade, BPC-157 has become one of the most widely used research peptides for injury recovery. The 250 mcg once or twice daily protocol has emerged as the de facto standard based on thousands of user reports. Some practitioners use weight-based dosing (2.5–5 mcg/kg) for more individualized protocols. Oral protocols for gut healing use higher doses (500–750 mcg/day) to account for reduced bioavailability.

Calculate Your BPC-157 Dose
BPC-157 is supplied as a lyophilized (freeze-dried) powder, typically in 5 mg or 10 mg vials. You reconstitute it with bacteriostatic water, then draw your dose using an insulin syringe. The concentration depends on how much water you add to the vial.
Worked Example:
- Vial size: 5 mg (5,000 mcg) of BPC-157
- Bacteriostatic water added: 2 mL
- Concentration: 5,000 mcg ÷ 2 mL = 2,500 mcg per mL
- Target dose: 250 mcg
- Volume to draw: 250 ÷ 2,500 = 0.1 mL = 10 units on an insulin syringe
Quick Reference — 5 mg Vial
| Bac Water Added | Concentration | 250 mcg Dose | Doses per Vial |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 5 units (0.05 mL) | 20 doses |
| 2 mL | 2,500 mcg/mL | 10 units (0.1 mL) | 20 doses |
| 2.5 mL | 2,000 mcg/mL | 12.5 units (0.125 mL) | 20 doses |
| 5 mL | 1,000 mcg/mL | 25 units (0.25 mL) | 20 doses |

How to Reconstitute BPC-157
BPC-157 comes as a lyophilized (freeze-dried) powder that must be reconstituted with bacteriostatic water before injection. This process is straightforward but requires clean technique to maintain sterility and peptide integrity.
Supplies Needed:
- BPC-157 lyophilized vial (5 mg or 10 mg)
- Bacteriostatic water (BAC water) — contains 0.9% benzyl alcohol as preservative
- Insulin syringes (29–31 gauge, 0.5 mL or 1 mL) for injection
- Alcohol swabs (70% isopropyl alcohol)
- Clean, flat workspace
- Optional: larger syringe (1–3 mL) for drawing bacteriostatic water if using a separate drawing needle
Steps
Wash Hands & Prepare Workspace
Wash hands thoroughly with soap and water. Lay out supplies on a clean surface: BPC-157 vial, bacteriostatic water, insulin syringe, and alcohol swabs.
Remove the Vial Caps
Flip off the plastic caps from both the BPC-157 vial and the bacteriostatic water vial. Swab both rubber stoppers with alcohol pads and let them air-dry for 10–15 seconds.
Draw Bacteriostatic Water
Using a fresh insulin syringe, draw your desired volume of bacteriostatic water. For a 5 mg vial, 2 mL is standard (yields 250 mcg per 0.1 mL / 10 units).
Add Water to the Peptide Calculator Vial
Insert the needle into the BPC-157 vial through the rubber stopper. Angle the needle so the water runs down the inside glass wall — never squirt directly onto the powder cake. Release the plunger slowly.
Dissolve Gently
Remove the syringe. Let the vial sit for 1–2 minutes, then gently swirl or roll between your palms until the powder is fully dissolved. The solution should be clear and colorless. Never shake.
Label & Refrigerate
Write the reconstitution date and concentration on the vial. Store refrigerated at 2–8°C. Use within 28–30 days.
Storage
- Unreconstituted (powder): Store refrigerated (2–8°C) for maximum shelf life; room temperature is acceptable for short periods (weeks) but reduces potency over time
- Reconstituted (in bacteriostatic water): Must be refrigerated at 2–8°C; use within 28–30 days
- Do not freeze: Freezing reconstituted BPC-157 can damage the peptide structure through ice crystal formation
- Protect from light and heat — keep the vial in its box or wrapped in foil, away from direct sunlight and temperatures above 25°C

BPC-157 Dosage by Goal
While BPC-157's core mechanism — tissue protection and repair through growth factor upregulation and angiogenesis — is consistent, the optimal dosing protocol varies by the type and severity of the condition being targeted.
Tendon & Ligament Injuries
The most researched and common use case. Animal studies show BPC-157 accelerates tendon-to-bone healing, increases collagen organization, and promotes angiogenesis at the injury site. Commonly used for tendonitis (Achilles, patellar, rotator cuff), ligament sprains, and chronic tendinopathy.
- Dose: 250–500 mcg per day (SubQ)
- Frequency: Once or twice daily
- Injection site: Subcutaneously as close to the injury as practical
- Duration: 4–8 weeks; chronic injuries may need up to 12 weeks
Gut Health & GI Healing
BPC-157's origin in gastric juice makes it particularly relevant for gastrointestinal conditions. Animal studies demonstrate healing of gastric ulcers, protection against NSAID-induced gut damage, and repair of intestinal inflammation (colitis models). Oral dosing is preferred for this application.
- Dose: 500–750 mcg per day (oral preferred)
- Frequency: Once or twice daily on an empty stomach
- Timing: 20–30 minutes before meals
- Duration: 4–8 weeks
Joint Pain & Arthritis
BPC-157 has shown anti-inflammatory and chondroprotective effects in animal models of joint damage. Users report benefits for osteoarthritis-related pain, joint stiffness, and cartilage-related complaints. Injection near the affected joint is standard.
- Dose: 250–300 mcg per day (SubQ)
- Frequency: Once or twice daily
- Injection site: Subcutaneously near the affected joint
- Duration: 4–8 weeks; may be repeated after a break
Post-Surgical Recovery
Some practitioners incorporate BPC-157 into post-surgical recovery protocols to support tissue healing, reduce inflammation, and potentially accelerate return to function. Dosing tends to be on the higher end and is typically started shortly after surgery (once cleared by the surgeon).
- Dose: 250–500 mcg per day (SubQ)
- Frequency: Twice daily
- Injection site: Near the surgical site (if accessible) or abdominal SubQ
- Duration: 4–8 weeks or as guided by the treatment provider
General Recovery & Wellness
Some users take BPC-157 at lower doses for general recovery support — reduced soreness from training, faster recovery from minor strains, and overall tissue maintenance. This is the least studied application and relies primarily on community reports.
- Dose: 150–250 mcg per day (SubQ)
- Frequency: Once daily
- Injection site: Abdominal subcutaneous (general systemic effect)
- Duration: 4–6 weeks, followed by a break
BPC-157 Injection Guide
Subcutaneous (SubQ) Injection — Step by Step
Wash Hands
Wash hands thoroughly with soap and water. Prepare a clean workspace with your syringe, alcohol swab, and reconstituted BPC-157 vial.
Swab the Vial Stopper
Wipe the rubber stopper of the BPC-157 vial with an alcohol swab. Let it air-dry for 10–15 seconds.
Draw Your Dose
Pull back the plunger to draw air equal to your dose volume. Insert the needle into the vial, push in the air, invert the vial, and slowly draw out your calculated dose. Tap out any air bubbles.
Choose the Injection Site
For local effect: inject subcutaneously as close to the injury as practical (e.g., next to the Achilles tendon, near the shoulder for rotator cuff). For systemic effect: the lower abdomen (2–3 inches from the navel) or upper thigh.
Clean the Injection Site
Swab the chosen injection site with a fresh alcohol pad. Allow to air-dry completely before injecting.
Inject
Pinch a fold of skin between your thumb and forefinger. Insert the needle at a 45-degree angle into the pinched skin fold. Push the plunger slowly and steadily. Withdraw the needle and apply light pressure with the alcohol swab if needed.
Dispose Safely
Place the used syringe immediately into a sharps container. Never recap or reuse needles.
Intramuscular (IM) Injection Notes
Some users prefer intramuscular injection, particularly when the injury involves deep muscle tissue. IM injection uses a slightly longer needle (typically 25–27 gauge, 1 inch) and is injected at a 90-degree angle directly into the muscle belly. Common IM sites include the deltoid, vastus lateralis (outer thigh), and gluteus. IM injection provides faster absorption but may be more uncomfortable than SubQ.
Local vs. Systemic Injection
- Local (near-injury): Preferred for targeted tissue repair. Delivers higher local concentrations to the injury site. Most common for tendon, ligament, joint, and muscle injuries.
- Systemic (abdominal SubQ): Used when the injury site is difficult to access, for general recovery, or for conditions that are not site-specific. BPC-157 has demonstrated systemic effects even when injected at distant sites.
- Both approaches work — local injection is generally preferred when feasible, but systemic injection remains effective.
BPC-157 Cycle Duration & Timing
BPC-157 is typically used in defined cycles rather than continuously. Most protocols run 4–8 weeks, with some users taking breaks between cycles. There is no established evidence of tolerance with BPC-157, but cycling is standard practice in the community.
| Protocol | Duration | Frequency | Notes |
|---|---|---|---|
| Standard cycle | 4–6 weeks | Once or twice daily | Most common; suitable for acute and moderate injuries |
| Extended cycle | 8–12 weeks | Once or twice daily | For chronic tendinopathy, old injuries, or post-surgical recovery |
| Repeat cycle | 4–6 weeks on, 2–4 weeks off, repeat | Once or twice daily during on-phase | For stubborn or recurring injuries; the break allows assessment of progress |
| Gut healing cycle | 4–8 weeks (oral) | Once or twice daily, empty stomach | Oral protocol for GI conditions; reassess after one cycle |
Time of Day
- Once daily: Morning is most common; some users prefer evening. Consistency matters more than the specific time of day.
- Twice daily: Split doses 8–12 hours apart (e.g., morning and evening) to maintain more stable peptide levels.
- Oral dosing: Take on an empty stomach, 20–30 minutes before a meal, for best GI tract exposure.
- No strict timing requirement — BPC-157 does not need to be timed around meals, workouts, or sleep (except for oral dosing).
BPC-157 Stacking Protocols
BPC-157 is frequently combined with other peptides to target multiple healing pathways simultaneously. The most popular stacks leverage complementary mechanisms — pairing BPC-157's localized tissue repair with systemic anti-inflammatory or growth-promoting peptides.
BPC-157 + TB-500 — “Wolverine Stack” (Tissue Repair + Systemic Healing)
The most widely used peptide stack for injury recovery. BPC-157 promotes localized tissue repair, angiogenesis, and growth factor expression, while TB-500 (Thymosin Beta-4) reduces systemic inflammation, promotes cell migration, and enhances flexibility. Together they address injury from both a local and systemic perspective.
BPC-157 + GH Secretagogues (Tissue Repair + Growth Hormone Support)
Pairing BPC-157 with a growth hormone secretagogue like Ipamorelin or CJC-1295 adds systemic growth hormone elevation to the localized repair effects of BPC-157. Elevated GH and IGF-1 levels support broader tissue recovery, collagen synthesis, and reduced recovery time.
| Compound | Dose | Frequency | Purpose |
|---|---|---|---|
| BPC-157 | 250 mcg SubQ | Once or twice daily (near injury) | Localized tissue repair and angiogenesis |
| Ipamorelin / CJC-1295 | 200–300 mcg each SubQ | Once daily (before bed) | GH pulse, IGF-1 elevation, systemic recovery support |
GH secretagogues are typically injected before bed on an empty stomach (fasted for 2–3 hours) to synergize with the natural nocturnal GH pulse. BPC-157 can be injected at any time and does not need to coincide with the GH secretagogue injection.

Safety, Side Effects & Contraindications
Common Side Effects
Mild and generally transient (reported by a minority of users):
- Nausea — more common with oral dosing, usually resolves within days
- Dizziness or lightheadedness — typically mild and short-lived
- Injection site redness, soreness, or minor swelling
- Headache — occasionally reported in the first few days of use
- Fatigue or mild lethargy — uncommon and usually temporary
Rare:
- Hot or cold flashes — reported anecdotally, mechanism unclear
- Changes in blood pressure — BPC-157 interacts with the NO system, which modulates vascular tone
Contraindications
- Active cancer or history of cancer — BPC-157 promotes angiogenesis (new blood vessel formation). While no studies have demonstrated tumor-promoting effects, the theoretical concern exists that enhanced angiogenesis could support tumor growth. Avoid use with active malignancies.
- Pregnancy and breastfeeding — no safety data exists for BPC-157 during pregnancy or nursing. Avoid use entirely.
- Active infections at the injection site — do not inject through infected, inflamed, or broken skin.
- Anticoagulant therapy — BPC-157 may interact with the NO system and platelet function. Exercise caution if taking blood thinners and consult your healthcare provider.
Drug Interactions
- NSAIDs: BPC-157 has shown protective effects against NSAID-induced gastric damage in animal studies. Some users specifically combine BPC-157 with NSAIDs to mitigate gut side effects, though this is not clinically validated.
- Blood thinners (warfarin, heparin, DOACs): Potential interaction via the NO system. Use with caution and medical supervision.
- Dopaminergic drugs: BPC-157 interacts with the dopamine system in animal models. If taking dopamine agonists or antagonists, consult your healthcare provider.
When to Stop
- Persistent nausea, vomiting, or GI distress that does not resolve within 3 days
- Signs of infection at the injection site (increasing redness, heat, pus, fever)
- Unexplained swelling, rash, or allergic-type reaction
- Any symptom that feels unusual or concerning — err on the side of caution
