BPC-157 and TB-500 are the dominant healing-and-recovery peptide combination in research-vendor catalogs. The mechanism rationale is straightforward: BPC-157 promotes angiogenesis and gut/tendon healing through a different pathway than TB-500 (thymosin beta-4), which accelerates dermal and corneal wound healing through actin-binding and cell migration mechanisms (Philp et al. 2013). Stacking the two compounds covers both healing axes simultaneously.
Research-context information only. Both BPC-157 and TB-500 are research peptides not approved by the FDA. Both are on the FDA 503A bulks Category 2 list (2023). Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
The buying problem is per-component verification — vendors must test BPC-157 (1,419.5 Da) and TB-500 (4,963 Da) independently to confirm both peptides actually shipped at labeled mass. Vendors that publish only "blend purity" without separate certificates have failed basic disclosure.
This guide covers documented per-mg pricing, blend COA verification, ratio selection, and red flags. For dosing context, see the BPC-157/TB-500 stack guide.

Understanding BPC-157/TB-500 Blend Pricing
The blend ships as a single lyophilized vial containing both peptides at a fixed ratio. Most vendors offer 10mg + 10mg (20mg total) as the standard size, with 5mg + 5mg (10mg total) as a smaller option. Three factors drive price: total mg in the vial, vendor markup, and whether the COA verifies both compounds separately.
Current Market Pricing (2026)
Vial Size Typical Price Range Price Per Total mg Best For 10mg blend (5+5) $50-90 $5-9/mg Tolerance testing, short cycles 20mg blend (10+10) $80-160 $4-8/mg Standard 8-12 week cycles — best all-around 30mg blend (15+15) $130-230 $4.30-7.70/mg Extended cycles 20mg × 5 (kit) $360-700 $3.60-7/mg Long protocols
The pattern: 20mg blends are the most-cited size in vendor sales data. Per-total-mg cost is typically 30-40% cheaper than buying BPC-157 and TB-500 separately.
Cost Per Cycle at Common Doses
Daily Dose Each Total Daily Days Per 20mg Vial 12-Week Cycle Cost (singles) 12-Week Cycle Cost (kit) 250mcg + 250mcg 0.5mg 40 days $260-450 $200-360 500mcg + 500mcg 1.0mg 20 days $520-900 $400-720 250mcg BPC + 500mcg TB 0.75mg ~27 days $400-700 $300-540

How to Verify BPC-157/TB-500 Blend Quality
A blend COA is harder to verify than a single-peptide COA because each peptide must be tested independently. The most common counterfeit pattern documented in community discussions: vendors substitute a smaller fragment for TB-500 (which costs more to synthesize at 43 residues) while keeping real BPC-157 in the vial.
What a Blend COA Should Include
Identity Confirmation — Both Peptides
Mass spectrometry confirming BPC-157 at 1,419.5 Da Mass spectrometry confirming TB-500 (Tβ4) at 4,963 Da Per-peptide amino acid sequence verification
Purity Testing — Both Peptides
HPLC purity at 98%+ for each peptide individually Two HPLC chromatograms (one per peptide), each showing a single dominant peak Water content (Karl Fischer) under 8%
Contamination Testing
Endotoxin levels Residual solvent analysis Heavy metals screening
How to Verify a Blend COA Is Legitimate
Two separate test reports — Per-peptide HPLC and mass spec, not a combined chromatogram. Third-party lab — Janoshik, MZ Biolabs, Colmaric most-cited. Verifiable task number at the lab's website. Recent date (within 6 months). Both molecular weights confirmed — 1,419.5 Da (BPC-157) AND 4,963 Da (TB-500).
Red Flags to Avoid
Single combined COA without per-peptide HPLC and mass spec Only in-house testing Prices below $3/mg total — likely substituted TB-500 fragment (TB-4 fragment at residues 17-23 costs much less to synthesize than full TB-500) No mass spec at all Vague "BPC/TB" labeling without confirming whether full TB-500 (43 residues) or a TB-4 fragment is shipping No contact information or cryptocurrency only No return or reship policy
Choosing the Right Vial Size
The 28-Day Stability Rule
Both BPC-157 and TB-500 reconstituted with bacteriostatic water and refrigerated are documented stable for roughly 28 days in published peptide-stability literature. With sterile water (no preservative), the window collapses to ~24 hours.
Vial Size At 250+250 mcg/day At 500+500 mcg/day At 250+250 mcg 5×/wk 10mg blend 20 days 10 days ~28 days 20mg blend 40 days ⚠️ 20 days ~56 days ⚠️ 30mg blend 60 days ⚠️ 30 days ⚠️ ~84 days ⚠️
⚠️ = exceeds 28-day reconstitution stability window
Practical implication: A 20mg blend at 500mcg+500mcg/day fits the 28-day window cleanly. At lower doses (250mcg+250mcg/day), the 20mg vial exceeds the window — staged reconstitution or smaller 10mg vials are commonly used.
Vial Size by Protocol
Tolerance testing context:
A 10mg blend vial (5mg + 5mg) is the smallest unit cited 10-20 days at standard doses
Standard 250+250 mcg/day community loading:
20mg blend vial with staged reconstitution at lower doses Or 10mg blend vial for the first 20 days 1-2 vials per month
Loading then maintenance (500mcg+500mcg loading, then 250mcg+250mcg maintenance):
20mg blend during 4-week loading phase (covers 20 days at full loading) Then 1× 20mg vial covers ~40 days of maintenance
Buying Multiple Smaller vs Kit
Factor Multiple 20mg Singles Kit (5× 20mg) Cost per total mg Higher ($4-8/mg) Lower ($3.60-7/mg) Freshness Same (lyophilized storage) Same Flexibility Can stop mid-cycle Committed to full kit Storage Easier (smaller volumes) Requires fridge space Shipping More frequent orders Single shipment
Common community pattern: 1-2× 20mg singles to validate source and assess loading phase, with kit purchases reserved for confirmed responders running 12+ week cycles.
Why the Blend Costs Less Than Buying Singles
A common question: how does a 20mg blend save 30-40% over buying 10mg BPC-157 + 10mg TB-500 separately? Three reasons:
1. Synthesis efficiency. TB-500 is the more expensive component (43 residues at $5-8/mg). Vendors batching TB-500 synthesis with BPC-157 capture economies of scale.
2. Single-vial packaging. One vial, one sterile fill, one COA cycle (sort of) is cheaper than two vials. Some vendors pass that savings to buyers.
3. Marketing — the blend is a higher-volume product. BPC-157/TB-500 is one of the top-selling research-peptide blends. Vendors compete on per-blend pricing more aggressively than on single-peptide pricing.
When a "20mg blend" is paid for at premium prices but mass spec doesn't show full TB-500 (4,963 Da), the buyer paid for a TB-4 fragment that synthesizes at 1/3 the cost. The COA is the mechanism that surfaces this.
