BPC-157 Dosage Guide: Tendon Repair, Gut Health & Injury Recovery
BPC-157 is the most researched repair peptide with 50+ published studies.[5] Standard dosing is 250-500mcg per injection. Whether you inject locally or systemically -- and whether you use acetate or arginate -- depends on what you are treating.

What Is the Right BPC-157 Dosage?
The most commonly referenced dose range is 250-500mcg per injection. For acute injury recovery, 500mcg twice daily is the standard loading approach, exploiting BPC-157's short 4-6 hour half-life to maintain consistent tissue concentrations.
For maintenance, general recovery, or gut health protocols, 250mcg once daily is widely used and better tolerated for longer cycles.
On higher doses: No strong evidence that doses above 500mcg produce proportionally better outcomes. The dose-response curve flattens above 500mcg in available data. More is not better here.
Should You Inject BPC-157 Locally or Systemically?
This is the most debated aspect of BPC-157 protocols. The answer depends on what you are treating.
Local Injection (at or near the injury)
Best for: tendon tears, ligament sprains, joint injuries, localized muscle damage.
- •Inject SubQ directly over or adjacent to the injury site
- •Higher local concentration where healing is needed
- •Promotes VEGF upregulation and angiogenesis locally
- •Intra-articular (into the joint) requires sterile technique
- •Close proximity is sufficient -- does not need to be exact
Systemic SubQ (abdomen or thigh)
Best for: gut healing, systemic anti-inflammatory effects, nerve injuries, inaccessible sites.
- •Standard insulin syringe into abdomen fat
- •Circulates systemically -- reaches gut, brain, all tissues
- •Preferred for IBD, leaky gut, GERD protocols
- •Easier to execute consistently
- •Some research suggests systemic is sufficient for musculoskeletal injuries too
The combined approach: Many injury protocols use both -- local injection near the site in the morning and systemic SubQ in the evening. No evidence this is required, but it is the most common high-effort protocol in the community.
BPC-157 Acetate vs Arginate: Which Form Should You Use?
- •Used in virtually all published BPC-157 research
- •Stable in bacteriostatic water for 4-6 weeks refrigerated
- •Standard choice for all injectable protocols
- •Poor oral bioavailability -- degrades in gastric acid
- •What most peptide suppliers sell as BPC-157
- •Salt form with significantly improved oral bioavailability
- •Resists gastric acid -- survives the stomach
- •Preferred for IBD, GERD, leaky gut, colitis protocols
- •Also injectable but less commonly used that way
- •Also called BPC-157 stable or BPC-157 oral form
Bottom line: Injectable injury protocol = acetate. Oral gut healing = arginate. SubQ for gut health = acetate works. Swallowing a capsule for gut health = arginate only.
BPC-157 Dosing Reference by Indication
| Indication | Dose | Frequency | Route | Cycle Length |
|---|---|---|---|---|
| Tendon / Ligament Repair | 500mcg | 2x daily | Local near injury + SubQ | 6-8 weeks |
| Joint Injury / Arthritis | 250-500mcg | 1-2x daily | Local or SubQ | 6-12 weeks |
| Muscle Tear / Strain | 500mcg | 2x daily | Local near injury | 4-6 weeks |
| Gut Healing (IBD, Leaky Gut) | 250-500mcg | 2x daily | Oral (arginate) or SubQ | 4-8 weeks |
| Nerve Injury | 250mcg | 1-2x daily | SubQ near site | 8-12 weeks |
| General Recovery / Maintenance | 250mcg | 1x daily | SubQ abdomen | 4-6 weeks |
| Wolverine Stack (+ TB-500) | 250mcg BPC + 2.5mg TB-500 | BPC 2x daily / TB-500 2x weekly | SubQ | 6-8 weeks |

How to Reconstitute BPC-157 for Injection
BPC-157 comes as lyophilized (freeze-dried) powder, typically in 5mg vials. Add bacteriostatic water (BAC water) to dissolve and achieve your target concentration.
Common example: 5mg vial + 2ml BAC water
Concentration
2,500mcg/ml
2ml added to 5mg vial
500mcg dose
20 units
on U-100 insulin syringe
250mcg dose
10 units
on U-100 insulin syringe
Add BAC water slowly along the vial wall. Do not inject directly onto the powder. Do not shake -- swirl gently. Store refrigerated, use within 4-6 weeks.
Calculate Your Exact Draw UnitsHow Long Should You Run a BPC-157 Cycle?
BPC-157 does not suppress the HPTA and does not require post-cycle therapy. Cycle length is driven by the healing goal, not suppression concerns.
Acute muscle strains, minor tendon irritation, short gut healing protocols
Moderate tendon tears, ligament sprains, chronic tendinopathy, IBD flares
Severe tendon ruptures, nerve injuries, chronic gut conditions, joint repair
Stacked with TB-500 (Wolverine Protocol), the same cycle structure applies. See the Stack Planner for the full evidence-graded protocol.
What Stacks Well with BPC-157?
BPC-157 + TB-500 (Wolverine Protocol)
The most evidence-backed repair stack. BPC-157 heals locally through VEGF and angiogenesis. TB-500 heals systemically through actin regulation and cell migration. Complementary mechanisms. Standard: 250-500mcg BPC-157 daily + 2-2.5mg TB-500 twice weekly.
BPC-157 + GHK-Cu (Skin & Collagen)
GHK-Cu drives collagen synthesis through a different pathway than BPC-157. Particularly relevant for connective tissue repair and skin integrity. Can be injected in separate SubQ sites or mixed in the same syringe.
Frequently Asked Questions
What is the standard BPC-157 dosage?
250-500mcg per injection. For acute injury, 500mcg twice daily during loading. For maintenance, 250mcg once daily. No strong evidence that doses above 500mcg produce better results.
Should I inject BPC-157 locally near the injury or systemically?
Local injection is preferred for musculoskeletal injuries. Systemic SubQ is preferred for gut healing. Many protocols combine both: local in the morning, systemic SubQ in the evening.
Does BPC-157 require post-cycle therapy (PCT)?
No. BPC-157 does not suppress the HPTA, does not affect testosterone, and is not androgenic. No PCT needed. Cycling off is common as precaution, not because of documented suppression.
Can I inject BPC-157 and TB-500 in the same syringe?
Yes. Both store in bacteriostatic water and are commonly mixed. Draw BPC-157 first, then TB-500. Use immediately after mixing. Separate injections are also fine for precision dosing.
