BPC-157 and TB-500 Stack: The Healing Protocol

The BPC-157 and TB-500 pairing is one of the most searched peptide stacks online, often nicknamed the 'Wolverine stack' after the comic-book character known for fast repair. The name is internet shorthand, not a description of what the compounds do. This is a neutral, third-person look at how the stack is structured in research references: the common figures, the daily versus weekly timing, the cycle length, and why the two are discussed together.

Both BPC-157 and TB-500 are research compounds, not approved for human consumption, and nothing here is medical or dosing advice. Every number below is an arithmetic reference point you can verify yourself with the BPC-157 calculator. Any decision about use belongs with a licensed clinician. For the head-to-head profile, see BPC-157 vs TB-500.

Why the two get stacked

The synergy rationale comes down to reach. In research models, BPC-157 is usually described as localized or site-directed, which is why some protocols place an injection near an area of interest. TB-500 is more often described as systemic, distributing more broadly regardless of where it is injected. Pairing them is framed as covering both a local and a body-wide profile at once.

• BPC-157: framed as localized, daily-frequency figures.
• TB-500: framed as systemic, larger weekly figure split across the week.
• Stack logic: two different reach profiles studied side by side, not a combined potency claim.

Common reference figures

Across the literature, BPC-157 figures are commonly discussed in a 250 to 500 mcg range on a daily frame. TB-500 figures are commonly discussed as 2 mg to 5 mg per week, often split into one or two administrations. These are reference points, not recommendations.

• BPC-157: typically a 5 mg or 10 mg vial, figures often in the 250 to 500 mcg range.
• TB-500: typically a 2 mg, 5 mg, or 10 mg vial, figures often 2 mg to 5 mg per week.
• Both ship as freeze-dried powder and must be reconstituted with bacteriostatic water before any volume can be drawn.

Worked reconstitution math

Concentration is vial strength divided by water volume. Draw volume is the target figure divided by concentration. A worked BPC-157 example: a 5 mg vial in 2 mL of bacteriostatic water gives 2.5 mg/mL. A 250 mcg (0.25 mg) figure at 2.5 mg/mL is 0.1 mL, which reads as 10 units on a U-100 insulin syringe. A 500 mcg figure is 0.2 mL, or 20 units.

A worked TB-500 example: a 10 mg vial in 2 mL gives 5 mg/mL. A 2 mg figure at 5 mg/mL is 0.4 mL, or 40 units. The same 2 mg from a 5 mg vial in 2 mL (2.5 mg/mL) is 0.8 mL, or 80 units. More water lowers concentration and raises the unit count for the same milligram figure.

• BPC-157, 5 mg in 2 mL (2.5 mg/mL): 250 mcg = 0.1 mL = 10 units; 500 mcg = 0.2 mL = 20 units.
• TB-500, 10 mg in 2 mL (5 mg/mL): 2 mg = 0.4 mL = 40 units; 5 mg = 1.0 mL = 100 units.
• Recompute from scratch any time you change vial size, water volume, or target figure.

Timing and frequency

The two peptides usually run on different schedules inside the same stack. BPC-157 references tend toward a daily frame because of its shorter, more localized profile. TB-500 references tend toward a larger weekly total split into one or two administrations, since it is framed as longer-reaching. A common structure pairs a small daily BPC-157 draw with a one-or-two-times-weekly TB-500 draw.

On whether to combine them in a single syringe, some protocols describe mixing compatible reconstituted peptides, but that is a handling question with stability and sterility tradeoffs. Read can you mix two peptides in one syringe before assuming it applies.

Cycle length and phases

Reference protocols often describe the stack over a span of several weeks. TB-500 in particular is sometimes split into a higher-frequency loading phase followed by a lower-frequency maintenance phase, where the per-draw figure stays the same and only the number of draws per week changes. For example, a loading week with two 2 mg draws totals 4 mg (80 units of liquid across the week at 5 mg/mL), while a maintenance week with one draw totals 2 mg (40 units).

These are arithmetic illustrations of how frequency changes the weekly total, not a schedule to follow. For the per-compound detail, see the TB-500 dosage guide and the BPC-157 dosage guide, and check how long to cycle peptides for general cycle framing.

Handling both vials

General references describe reconstituted peptides as kept refrigerated and used within roughly a few weeks. Bacteriostatic water is the usual diluent for multi-draw vials because the preservative limits microbial growth between draws. Aim the water down the vial wall and swirl rather than shake to avoid foaming. With two vials running at once, label each one clearly so the concentrations never get mixed up. The broader peptide dosage calculator isolates the same steps for any vial. See the disclaimer for the full research-use framing.
