BPC-157 + TB-500 5/5 blend
Last verified: 2026-05-01
At a glance
| Composition | 5 mg BPC-157 + 5 mg TB-500 in a single 10 mg vial |
| Class | Pre-mixed research-chemical blend; not an FDA-recognised combination |
| Typical route | Subcutaneous injection (IM possible; oral is BPC-157-only territory and the blend isn’t designed for it) |
| Typical dose | 250–600 mcg total daily, or 1.75–4 mg total weekly across split doses |
| UK and US status | Not approved as a medicine in any jurisdiction. Sold as a research chemical labelled “not for human consumption.” |
What it is
This is a pre-mixed blend containing equal masses of two of the most commonly stacked recovery / repair peptides: 5 mg BPC-157 and 5 mg TB-500 in a single vial. Many research-chemical vendors sell this as a convenience SKU because the two compounds are so frequently combined; the blend ships ready to reconstitute as a single solution rather than reconstituting two vials and drawing into the same syringe.
It is not a separate compound — it’s just BPC-157 and TB-500 sharing a vial. The full pharmacology, evidence base, sensitive-systems framing, and safety considerations are covered in the per-component pages:
- BPC-157 — gastric protective pentadecapeptide; tissue repair, gut, vasculature, mast-cell-active in some users
- TB-500 — thymosin β4 fragment; actin-binding, soft-tissue and vascular recovery, longer half-life
This page covers only what’s blend-specific: the math, when the convenience matters, and what the equal-mass formulation does and doesn’t change.
When the blend makes sense
The blend is mechanically convenient when:
- The user runs both compounds at the same dose and frequency
- They want one injection rather than two (or one syringe draw rather than two)
- Equal-component dosing is the right choice for the protocol — typically a recovery / orthopaedic phase rather than a sensitive-systems gut-protocol where BPC alone is more appropriate
The blend is not the right choice when:
- The user wants to titrate the two compounds independently (e.g. starting BPC at 100 mcg for sensitive-systems tolerance while running TB at full dose)
- BPC-only or TB-only use is the actual indication (gut healing → BPC alone; soft-tissue injury → TB-500 carries the bulk of the published evidence; combining is an additional choice)
- The user wants different routes or frequencies for the two components
For users in either of those situations, separate vials are better — same compounds, same protocol logic, more flexibility.
The math
The blend is straightforward to plan because both components are at the same mass concentration:
10 mg blend (5 mg BPC + 5 mg TB), 3 mL BAC water (the standard)
- Total concentration: 3.33 mg/mL (3,333 mcg/mL total = 1,667 mcg/mL of each component)
- 250 mcg total = 0.075 mL = 7.5 units (rounds to 7 or 8)
- 500 mcg total = 0.15 mL = 15 units
- 600 mcg total = 0.18 mL = 18 units (the most-cited daily dose)
10 mg blend, 2 mL BAC water (denser concentration for higher-dose protocols)
- Total concentration: 5 mg/mL (5,000 mcg/mL total)
- 500 mcg total = 0.1 mL = 10 units
- 1000 mcg total = 0.2 mL = 20 units
The Peptrax Vial Plan calculator handles both blend-aware presets — dose_basis: total for total-blend dosing, and dose_basis: component for users targeting a specific BPC or TB amount with the other component coming along for the ride.
Storage and stability
Same as the per-component peptides:
- Reconstituted with BAC water: ~28 days refrigerated (2–8°C). Conservative end of the spread is 14–21 days; middle is 28; some practitioners run vials longer with no obvious issue.
- Reconstituted with plain sterile water: single-use, discard within 24 hours.
- Do not freeze. Store at the back of the refrigerator where temperature is most stable.
For 600 mcg/day from a 10 mg blend at 3 mL BAC: ~16 doses → 16 days, comfortably within shelf life.
What the blend doesn’t change
The clinical picture, sensitive-systems framing, sourcing concerns, and safety considerations are the union of the BPC-157 and TB-500 profiles. The per-component pages cover:
- Mechanism for each compound
- Evidence base (and the genuine evidence gaps for both)
- Sensitive-systems profile, including the BPC-157 mast-cell signal that’s relevant for MCAS users
- Cancer / IGF-1 / mitogenic concerns where applicable
- Route-specific guidance (BPC-157 oral has its own profile; TB-500 is injection-only in practice)
- Quality and sourcing caveats common to research-chem peptide markets

What to track in Peptrax
The blend is one entry in the app, but the protocol is two compounds — log it that way. If the user is running the blend with the goal of orthopaedic recovery (the dominant use case), the per-week total dose, total weeks on, and the specific tissue / injury rated weekly on the same scale across the cycle is the read that lets the user decide whether the protocol worked. If sensitive-systems tolerability becomes an issue mid-cycle, the right move is usually splitting back into separate vials so BPC and TB can be titrated independently — the blend’s convenience disappears once the two components need different dose schedules.
