Wolverine Stack Dosage Chart: Daily and Weekly Doses
The Wolverine stack is the forum nickname for BPC-157 plus TB-500, and most dosage charts for it assume two gray-market vials and a loading phase. The prescribed version is simpler: one blend vial, 20 units, Monday through Friday. This page puts the circulating protocols and the prescribed numbers side by side, answers the per-day and per-week questions in plain milligrams, and shows why you do not need a calculator for any of it.

Key Takeaways
- The Wolverine stack is not a product, so it has no official dosage. It is a forum nickname for combining BPC-157 and TB-500, and every chart you find online is one community's convention, not a validated protocol.
- Circulating research protocols typically run BPC-157 at 250 to 500 mcg daily and TB-500 at 2 to 2.5 mg once or twice a week, often with a front-loaded "loading phase". None of those numbers come from human dose-finding trials.
- The prescribed equivalent at PeRx is a single blend vial at 3 mg BPC-157 and 3 mg TB-500 per mL. The dose is 20 units (0.2 mL) subcutaneously, Monday through Friday: 0.6 mg of each peptide per injection, 3 mg of each per week.
- The cycle is 6 weeks on, 6 weeks off, with no loading phase and no ramp. Day one and day thirty are the same 20 units. A capsule version exists at 500 mcg of each peptide, one every morning, seven days a week.
- You do not need a dosage calculator for the prescribed vial. At this concentration, milligrams of each peptide equal units times 0.03, and the prescription is a fixed 20 units. Your label governs over any chart, this one included.

Your Label Governs
The prescribed numbers on this page describe the protocol as written through PeRx, where a licensed provider reviews your intake before anything ships. The directions on your own prescription label outrank any chart on the internet, including this one. If your label says something different, follow the label and message your provider.
The Wolverine Stack Dosage Chart
First, the naming problem. "Wolverine stack" is not a drug, a brand, or a regulated product. It is the nickname forums attached to running BPC-157 and TB-500 together, and because the name has no owner, it has no official dose. What the stack is and where the name came from is covered in the Wolverine stack peptides guide; how it differs from the GLOW and KLOW blends is decoded in GLOW vs KLOW vs Wolverine stack. This page is only about the numbers.
The chart below shows the stack as it is actually prescribed through PeRx: both peptides compounded into one vial at 3 mg of each per mL, dosed at 20 units on a U-100 insulin syringe. Every row follows from those two facts.
| Measure | BPC-157 | TB-500 | Combined |
|---|---|---|---|
| Per injection (20 units, 0.2 mL) | 0.6 mg | 0.6 mg | 1.2 mg |

| Per day, Saturday and Sunday | 0 | 0 | 0 |

That is the whole chart, and its shortness is the point. One concentration, one draw, one schedule. If you want the deeper arithmetic behind these rows, vial contents, doses per vial, unit-to-milligram conversions at every syringe marking, cost per injection, all of the full units math lives in the BPC-157/TB-500 dosage chart. This page stays focused on what people searching for the Wolverine stack actually ask: how the forum numbers map onto the prescribed ones.
Forum Protocols vs the Prescribed Version
Most Wolverine stack charts circulating online assume two separate gray-market vials, because that is how the research-chemical market sells the peptides. The protocol shape that repeats across forums looks roughly like this: BPC-157 at 250 to 500 mcg injected once or twice daily, and TB-500 at 2 to 2.5 mg once or twice a week, often front-loaded for the first four to six weeks in what forums call a loading phase, then dropped to a smaller maintenance shot every week or two. Cycle lengths of four to eight weeks are typical.
To be clear about what those numbers are: community conventions built for unregulated products, not doses derived from human trials. Neither peptide has published human dose-finding data, so no forum chart can claim a clinical basis; this page describes those protocols so you can translate them, not run them. They also carry a hidden variable. A research-chemical powder has whatever concentration the buyer creates when they add water to the vial, so two people following the same chart can be injecting meaningfully different amounts.

| Vials | Two separate vials, mixed by the buyer | One blend vial, ships fully reconstituted and ready to use |
| BPC-157 | 250 to 500 mcg, once or twice daily | 0.6 mg once daily, Monday through Friday |
| TB-500 | 2 to 2.5 mg, once or twice weekly | 0.6 mg once daily, Monday through Friday |
| Loading phase | Often, for TB-500 | None; every dose is the same 20 units |
| Weekly TB-500 total | Roughly 2 to 5 mg | 3 mg |

Read across the weekly row and the two versions land closer than the schedules suggest. A mid-range forum protocol delivers 2 to 3.5 mg of BPC-157 and 2 to 5 mg of TB-500 per week; the prescribed blend delivers 3 mg of each. The real difference is rhythm. Separate vials let forums schedule TB-500 as a big infrequent shot while BPC-157 runs daily. A 1:1 blend cannot split the schedule, so both peptides arrive in smaller daily amounts on the same weekday clock. The reasoning behind putting them in one vial in the first place is laid out in why we pair BPC-157 and TB-500.
BPC/TB-500
The prescribed form of the Wolverine stack at PeRx is a single 5 mL vial carrying both peptides at 3 mg per mL each, prescribed by a licensed provider and compounded at a US-based 503A pharmacy. It ships fully reconstituted and ready to use, refrigerated, with insulin syringes in the box.
No mixing, no concentration math, no separate TB-500 schedule to manage. One 20-unit draw delivers both peptides in a fixed 1:1 ratio. $299 for the monthly vial, with an oral capsule version at $225 if needles are a dealbreaker.
Daily Dosage: What Per-Day Actually Means
Searches for Wolverine stack daily dosage stumble over a units mismatch: forum charts quote BPC-157 in micrograms and TB-500 in milligrams, and the two peptides run on different clocks. On the prescribed blend the per-day answer is one number. Dosing days deliver 0.6 mg of BPC-157 and 0.6 mg of TB-500, which is 1.2 mg of combined peptide. Saturday and Sunday deliver nothing, and that is the schedule working as written, not a missed dose.
Two translation traps are worth flagging. First, when a forum chart says "500 mcg per day", it means BPC-157 alone; the blend's 0.6 mg per dose sits just above that, with the TB-500 riding along in the same draw. Second, per-day figures do not transfer between products. A chart calling for 2.5 mg of TB-500 in one shot is describing a standalone vial at some other concentration; chasing it with the blend would mean drawing more than 80 units and taking 2.5 mg of BPC-157 along for the ride. The only per-day number that applies to your vial is the unit count on its label.
Units on an Insulin Syringe
The prescription is written in units because insulin syringes are marked in units. On a U-100 syringe, 100 units is 1 mL, so each unit is 0.01 mL and the prescribed 20 units is 0.2 mL. That mark sits at different heights on a 0.3, 0.5, or 1 mL barrel but means the same volume on all three, so draw to the printed marking rather than judging fill height by eye. The injection goes under the skin, close to the recovering area, rotating spots. Where to inject BPC-157 maps site selection, and How to Take Peptides walks the full sequence from swab to sharps container. A row-by-row units table at every syringe marking is in the full dosage chart.
The Capsule Version
The same peptide pair comes as an oral capsule for people who want the stack without a syringe: 500 mcg of BPC-157 and 500 mcg of TB-500 per capsule, one capsule every morning on an empty stomach with water only, waiting at least 30 minutes before food or coffee. Unlike the injectable, capsules run seven days a week, which puts the nominal weekly intake at 3.5 mg of each peptide against the injectable's 3 mg.
Nominal is the operative word. An injected milligram bypasses digestion; an oral milligram has to survive the gut first, and the two peptides fare very differently there. BPC-157 was isolated from gastric juice and is unusually stable in stomach acid, which is why an oral format exists at all. TB-500 is a larger molecule with poor oral survivability, so the capsule is best understood as a gut-directed BPC-157 product with a partial TB-500 contribution, not a milligram-for-milligram swap for the injection. The trade-offs between routes are laid out in oral vs injectable peptides. The capsules are $225 for a 30-day bottle.
Cycle Length and Frequency
The prescribed cycle is 6 weeks on, then 6 weeks off, and the prescription says in plain words not to use it continuously. Six weeks at five doses per week is 30 injections and 36 mg of combined peptide. Forum cycles of four to eight weeks orbit the same bounded shape. What the prescribed version adds is that restarting is a provider decision: if there is still a reason to continue after the off period, the next cycle goes back through review instead of rolling over automatically.
The off period is not decoration. BPC-157 has a large preclinical literature, nearly all rodent work, with essentially no controlled human trials behind the doses used in practice. TB-500 is thinner still: the human data that exists belongs to full thymosin beta-4, which reached early-phase wound-healing trials, and the TB-500 fragment itself has no published human dosing data. A bounded cycle caps cumulative exposure while that evidence gap stands. What the pair is used for and what the underlying evidence looks like week by week is covered in the main BPC-157 and TB-500 guide.

Two Rules That Ride With the Prescription
No NSAIDs during the cycle: no ibuprofen, naproxen, or aspirin, including the versions tucked inside combination cold and headache products. And brief lightheadedness after an injection is possible; sit down for your first several doses and stay seated a few minutes. If lightheadedness lasts past 15 to 20 minutes, if you faint, or if you have swelling of the face or throat, trouble breathing, or a racing heartbeat, treat it as an emergency.
The Dosage Calculator Question
People search for a Wolverine stack dosage calculator because the gray-market version genuinely needs one. When you buy powder and add your own water, the concentration is whatever you made it, and converting a chart's micrograms into syringe units requires arithmetic every single time. The formula, for the record, is simple: milligrams per injection equals units drawn, times 0.01 mL per unit, times the vial's mg-per-mL concentration.
The prescribed blend makes the calculator unnecessary. The pharmacy fixes the concentration at 3 mg of each peptide per mL, so milligrams always equal units times 0.03, and 20 units is 0.6 mg of each, every time. Because the prescription is a fixed 20 units rather than a weight-scaled or titrated dose, there is nothing to compute and nothing to adjust on your own. If a number on some other chart is tempting you toward a bigger draw, that is a conversation for your provider, not a calculation.

Wolverine Stack: BPC-157 and TB-500, Explained
The wolverine stack is two peptides, BPC-157 and TB-500, run together for injury recovery. This guide covers where the comic-book name came from, what each peptide contributes, what the research honestly supports, the side effects and open questions, what forum reports get right and wrong, and how the prescribed single-vial version differs from buying two research vials.
Is TB-500 FDA Approved? Parent in Phase 2 Trials
No. TB-500 is not FDA-approved. But its parent molecule, Thymosin Beta-4, has been studied in multiple human clinical trials for wound healing and cardiac repair. RegeneRx Biopharmaceuticals ran these trials through Phase 2 before pausing development. TB-500 is the synthetic version used in compounded peptide therapy.
KLOW Peptide Dosage: Chart, Frequency, Cycle
Nearly every KLOW dosage chart online describes an 80 mg research vial that someone mixes at their kitchen table. The KLOW a physician actually prescribes is a different product with different math. This is the dosing as written on the PeRx prescription: units on the syringe, days per week, weeks per cycle, and what the gray-market charts get wrong.
