BB (BPC-157 + TB-500) Dosing Guide
The Wolverine stack in one vial — dosed by the BPC-157 number, with TB-500 riding along 1:1.
BB is BPC-157 and TB-500 together in one vial, 10 mg of each. Because the ratio is fixed, you cannot dose the two separately — every source handles this the same way: pick the BPC-157 dose you want, and accept the matching amount of TB-500 that comes with it. That means the TB-500 is spread out daily instead of in the big twice-weekly shots used on its own.
At a glance
- Typical dose
- 1 mg of blend per injection = 500 mcg BPC-157 + 500 mcg TB-500
- How often
- Once a day; some use 5 days on / 2 off
- Route
- Subcutaneous — near the injury or in the abdomen
- Timing
- Morning on an empty stomach is the common suggestion
- How long
- 6–12 weeks (8–12 most cited), then 2–4 weeks off
- Vial size
- 20 mg (10 mg BPC-157 + 10 mg TB-500)
How much
The convention is 1 mg of blend per injection — 500 mcg of BPC-157 and 500 mcg of TB-500 — once a day. The range is 0.5–2 mg of blend a day (250 mcg to 1 mg of each).
The daily TB-500 works out to about 3.5 mg a week, which roughly matches the weekly total of a solo TB-500 loading phase. Several sources note that a 1:1 blend delivers less TB-500 per shot than the solo 2.5 mg convention; if you want a true TB-500 loading dose, they suggest adding a separate TB-500 vial rather than pushing the blend higher (which would overshoot the BPC-157).
How often & when
Once daily is the most common; 5 days on / 2 off is the main alternative. Some guides run a heavier first week or two (for example 20 units) before settling at 10 units.
Inject subcutaneously, either near the injury or in the abdomen. Morning on an empty stomach is the frequent suggestion.
How long
6–12 weeks, with 8–12 weeks the most-cited course, followed by a 2–4 week break.
Mixing the vial
Doses below are for a standard U-100 insulin syringe (100 units = 1 mL). The formula: units = dose in mg ÷ concentration in mg/mL × 100. Bacteriostatic water is the usual diluent. A standard peptide vial holds about 3 mL of liquid at most — the store’s vials included — so every row below stays at or under 3 mL. Guides elsewhere that call for 4–5 mL will not fit.
| Vial | Water added | Concentration | Doses in units |
|---|---|---|---|
| 20 mg blend | 2 mL | 10 mg/mL total (5 mg/mL of each) | 10 units = 1 mg blend = 500 mcg BPC + 500 mcg TB-500 · 5 units = 250 mcg of each · 20 doses of 10 units |
| 20 mg blend | 3 mL | 6.67 mg/mL total | 10 units ≈ 333 mcg of each · 15 units = 500 mcg of each |
With 2 mL, one unit is 50 mcg of each peptide — the same clean math as a solo 10 mg BPC-157 vial. At 10 units a day the vial lasts 20 days.
How to reconstitute
Not sure how to mix the vial? Our free Reconstitution Calculator walks you through it: enter the vial size, how much bacteriostatic water you're adding and the amount you want per dose, pick your syringe, and it tells you exactly what mark to draw to, the concentration, and how many doses the vial holds — with a syringe diagram and a step-by-step worked example. For a multi-peptide vial like this one, the Blend Reconstitution tool shows how much of each peptide lands in a single draw.
Practical tips
- Refrigerate after mixing and use within about 30 days. TB-500 is considered the less stable of the two, so do not stretch it.
- Rotate sites; the volume is small (0.1–0.2 mL).
- You cannot adjust the ratio. Dose to the BPC-157 target and let the TB-500 follow.
- For a TB-500-heavy protocol (big twice-weekly loading shots), add a separate TB-500 vial rather than increasing the blend.
What the evidence looks like
Evidence level
No trial has tested the combination. The individual compounds are supported mainly by animal data (see the BPC-157 and TB-500 guides), so blend dosing is pure community convention.
For what the compound is and how it is studied — mechanism, research history and the primary literature — read the reference entries: BPC-157, TB-500.

Common questions
How many units of BB do I take?
10 units a day is the standard with 20 mg mixed in 2 mL — that is 500 mcg of BPC-157 and 500 mcg of TB-500.
Is the TB-500 dose too low in a 1:1 blend?
Per shot, yes, compared with the 2.5 mg solo convention — but daily dosing adds up to roughly a loading-phase weekly total. Sources that want more TB-500 add a separate vial.
How long does a 20 mg BB vial last?
20 days at 10 units a day; 40 days at 5 units.
