BPC-157 + KPV + TB-500 Stack Guide

The Inflammation & Recovery Protocol — a comprehensive 3-peptide stack combining gut repair, molecular anti-inflammation, and systemic tissue healing for chronic inflammatory conditions and autoimmune support.

Stack Overview

The BPC-157 + KPV + TB-500 stack is the most comprehensive anti-inflammation and recovery peptide combination available. It pairs BPC-157's localized tissue repair and gut mucosal healing with KPV's potent molecular anti-inflammation (NF-κB inhibition) and TB-500's systemic cell migration and tissue remodeling — addressing inflammation from molecular, local, and systemic levels simultaneously.

Why This Stack Works

This stack is effective because it attacks inflammation and tissue damage from three fundamentally different angles. Rather than relying on a single mechanism, the combination provides molecular-level, localized, and systemic coverage for comprehensive inflammatory management.

KPV: The Molecular Anti-Inflammatory

  • NF-κB inhibition: directly suppresses NF-κB signaling, the master transcription factor that drives inflammatory cytokine production (TNF-α, IL-6, IL-1β)
  • Alpha-MSH fragment: a tripeptide (Lys-Pro-Val) derived from the C-terminal of alpha-melanocyte-stimulating hormone, retaining its anti-inflammatory properties without melanogenic effects
  • Antimicrobial activity: demonstrates direct antimicrobial properties against common gut pathogens, supporting gut microbiome balance
  • Mucosal protection: reduces inflammatory infiltration in intestinal mucosa, with demonstrated benefit in colitis models

BPC-157: The Local Repair Agent

  • Angiogenesis: upregulates VEGF (vascular endothelial growth factor), promoting new blood vessel formation to deliver nutrients and oxygen to damaged tissue
  • Gut mucosal healing: protects and repairs gastrointestinal mucosa, with demonstrated benefit in ulcer, fistula, and inflammatory bowel models
  • Growth factor expression: increases EGF, FGF, and other factors that stimulate cell proliferation and tissue remodeling
  • Nitric oxide modulation: interacts with the NO system to regulate blood flow, inflammation, and repair signaling

TB-500: The Systemic Healer

  • Actin regulation: sequesters G-actin to promote cell migration, allowing repair cells to reach damaged tissue throughout the body
  • Systemic anti-inflammation: reduces inflammation throughout the body, creating a favorable healing environment beyond any single injury site
  • Tissue remodeling: promotes tissue remodeling and reduces scar tissue formation, improving functional recovery
  • Blood cell production: stimulates new blood cell formation and improves endothelial cell function

The Triple Synergy

KPV suppresses the inflammatory cascade at its molecular root (NF-κB), reducing the production of inflammatory cytokines that perpetuate tissue damage. BPC-157 then creates a favorable local healing environment with new blood vessels, growth factors, and mucosal protection. TB-500 complements both by driving systemic cell migration and tissue remodeling. The result: inflammation is addressed at the source (KPV), damaged tissue is actively repaired (BPC-157), and healing cells are mobilized throughout the body (TB-500).

1

Wash Hands & Prepare Workspace

Wash hands thoroughly. Lay out supplies: peptide vials, bacteriostatic water, insulin syringes, and alcohol swabs on a clean surface.

2

Swab All Vial Stoppers

Remove plastic caps and swab the rubber stoppers of each peptide vial and the bacteriostatic water vial with alcohol pads. Let air-dry for 10–15 seconds.

3

Add Water to Each Peptide Vial

Draw the appropriate volume of bacteriostatic water for each vial. Insert needle and direct the stream down the inside glass wall — never squirt directly onto the powder. Release slowly. Reconstitute each vial separately.

4

Dissolve Gently

Let each vial sit for 1–2 minutes, then gently swirl or roll between palms until fully dissolved. Solution should be clear and colorless. Never shake.

5

Label & Refrigerate

Write the reconstitution date and concentration on each vial. Store all vials refrigerated at 2–8°C. Use within 28–30 days.

Timing & Daily Schedule

BPC-157 and KPV are dosed daily, while TB-500 follows a different schedule. Here is how a typical week looks during the loading phase (weeks 1–4):

DayBPC-157KPVTB-500
Monday250 mcg AM + 250 mcg PM500 mcg AM2.5 mg
Tuesday250 mcg AM + 250 mcg PM500 mcg AM
Wednesday250 mcg AM + 250 mcg PM500 mcg AM
Thursday250 mcg AM + 250 mcg PM500 mcg AM2.5 mg
Friday250 mcg AM + 250 mcg PM500 mcg AM
Saturday250 mcg AM + 250 mcg PM500 mcg AM
Sunday250 mcg AM + 250 mcg PM500 mcg AM

Timing Notes

  • BPC-157: Split doses 8–12 hours apart (e.g., 8 AM and 8 PM). For oral dosing, take on an empty stomach 30 minutes before food.
  • KPV: Take once daily in the morning. For oral dosing, take with oral BPC-157 on an empty stomach. For SubQ, inject at any convenient time.
  • TB-500: Can be injected at any time of day. Space injections 3–4 days apart during loading (e.g., Monday/Thursday or Tuesday/Friday).
  • Same session: All three peptides can be administered in the same session. Use separate syringes for each injectable. No waiting period between injections.
  • Injection sites: BPC-157 near the injury or abdomen; KPV in the abdomen; TB-500 works systemically from any SubQ site (abdomen is most convenient).

Cycling & Duration

This stack is typically run for 6–8 weeks, with the option to extend to 12 weeks for chronic inflammatory conditions. Periodic reassessment is important for longer cycles.

When to Extend to 12 Weeks

  • Chronic inflammatory bowel conditions: Long-standing IBD, Crohn's-related inflammation, or chronic colitis may require extended duration for meaningful mucosal remodeling
  • Autoimmune-related tissue damage: When inflammation is driven by autoimmune processes, longer suppression of the inflammatory cascade allows more complete tissue repair
  • Multiple inflammatory sites: When addressing both gut inflammation and systemic joint/tissue inflammation simultaneously, a longer cycle provides adequate healing time for all affected areas

Why Take a Break?

The break period is particularly important for this stack due to KPV's immune-modulating effects. It serves to: (1) assess healing progress without peptide support, (2) confirm that improvement is structural rather than just symptomatic, (3) allow the immune system to return to baseline signaling, and (4) monitor for any signs of excessive immunosuppression from prolonged KPV use.

Safety, Side Effects & Contraindications

Common Side Effects

  • Injection site redness, soreness, or minor swelling — the most common report for all injectable peptides
  • Mild skin flushing — more common with KPV due to its alpha-MSH origin; typically transient
  • Mild nausea — more common with BPC-157, especially oral dosing; usually resolves within days
  • Transient fatigue or lethargy — occasionally reported
  • Headache — may occur in the first few days of use
  • Dizziness or lightheadedness — rare, typically mild and short-lived

Contraindications

  • Active cancer or history of cancer: BPC-157 promotes angiogenesis and TB-500 promotes cell migration, which could theoretically support tumor growth. Avoid use with active malignancies.
  • Pregnancy and breastfeeding: No safety data exists for any of these peptides during pregnancy or nursing. Avoid entirely.
  • Active immunosuppressive therapy: KPV modulates immune signaling. Combining it with immunosuppressive medications may lead to excessive immune dampening. Consult your healthcare provider.
  • Active infections at injection site: Do not inject through infected, inflamed, or broken skin.
  • Anticoagulant therapy: BPC-157 interacts with the NO system and may affect platelet function. Consult your healthcare provider if taking blood thinners.

Stack-Specific Safety Notes

  • No known negative interaction: BPC-157, KPV, and TB-500 have not been shown to interfere with each other. They operate through different mechanisms and pathways.
  • KPV immunomodulation: KPV's NF-κB inhibition is beneficial for reducing inflammation but may dampen the immune response with prolonged use. Monitor for increased frequency of minor infections during extended cycles.
  • Increased angiogenic load: Both BPC-157 and TB-500 promote aspects of tissue repair involving vascularization. This reinforces the theoretical concern about use with active cancers.
  • Separate syringes: Use dedicated syringes for each injectable peptide to avoid any potential compatibility issues in solution.

Common Inflammation Stack Mistakes

Avoid these common errors to get the most out of your BPC-157 + KPV + TB-500 protocol:

Not using the oral route for gut-focused protocols

When targeting gut inflammation (IBD, leaky gut, colitis), oral administration of BPC-157 and KPV delivers the peptides directly to the GI mucosa. SubQ injection provides systemic benefits but misses the direct local action on gut tissue. For gut-focused goals, oral dosing on an empty stomach is essential.

Expecting quick results with chronic inflammation

Chronic inflammatory conditions (autoimmune disorders, long-standing gut inflammation) develop over months or years. Peptides will not reverse this in days. Allow 4–6 weeks minimum for meaningful improvement and complete the full 6–8 week cycle before assessing whether the protocol is working.

Stopping the protocol too early

Symptom improvement after 2–3 weeks does not mean the underlying inflammation is resolved. Inflammatory tissue remodeling takes 6–8 weeks minimum. Stopping early risks relapse and incomplete healing. Complete the full cycle duration.

Using only one or two peptides when the full stack is needed

Each peptide in this stack addresses a different aspect of the inflammatory cascade: KPV targets molecular NF-κB signaling, BPC-157 handles localized tissue repair, and TB-500 provides systemic cell migration and healing. For comprehensive chronic inflammation, all three mechanisms work together. Omitting one leaves a gap in coverage.

Skipping the TB-500 loading phase

TB-500 requires a loading phase (2–2.5 mg twice weekly for 4–6 weeks) to build up systemic levels. Starting at the maintenance dose provides inadequate tissue saturation and delays the systemic anti-inflammatory benefit that complements BPC-157 and KPV.

Mixing all three peptides in the same syringe

Stability and compatibility data for combining reconstituted BPC-157, KPV, and TB-500 in one syringe is not established. Use separate syringes for each peptide to ensure integrity and accurate dosing. For oral peptides, BPC-157 and KPV capsules can be taken together.

Not monitoring for immunosuppression with prolonged KPV use

KPV is a potent anti-inflammatory that modulates immune signaling pathways. Extended use beyond 8–12 weeks without breaks may lead to excessive dampening of the immune response. Watch for increased frequency of minor infections, slow wound healing, or unusual fatigue as potential signs.

Neglecting to refrigerate reconstituted vials

All three peptides must be refrigerated at 2–8°C after reconstitution. Room temperature storage accelerates degradation. Use within 28–30 days of reconstitution. This applies to BPC-157, KPV, and TB-500 equally.
